+* All binaries should be built inside the bin/ folder.
+* All hardcoded variables should be defined in a central place and accessed from there directly, so that the amount of work needed to change a config is significantly less.
+* Log files should be written into the logs/ folder.
+* All protobuf and grpc service file definitions should be in the proto/ folder.
+* Always check whether the test cases pass from a cold start -- without having previously built containers, volumes, and pods.
+* A sample experiment file is in tests/sample_experiment.yml. This file should be used with the CLI to test whether the system can actually run experiments. If the experiment works and all results are generated and they can be listed, viewed, and downloaded, and is organized according to the project it was grouped under.
+* Always keep the docs/ and README.md files up to date with the current state of the code. This is a must. Out of sync docs and README is unacceptable.

+# Airavata Scheduler
+
+A production-ready distributed task execution system for scientific computing experiments with a crystal-clear hexagonal architecture, cost-based scheduling, and comprehensive data management.
+
+## 🎯 Conceptual Model
+
+The Airavata Scheduler is built around **6 core domain interfaces** that represent the fundamental operations of distributed task execution, with a **gRPC-based worker system** for task execution:
+
+```
+┌─────────────────────────────────────────────────────────────────┐

+│ • Register storage │ • Unix permissions │ • Generate tasks │
+│ • Validate access │ • Encrypt/decrypt │ • Submit for exec│

+│ TaskScheduler │ DataMover │ WorkerLifecycle │
+│ • Cost optimization │ • 3-hop staging │ • Spawn workers │
+│ • Worker distrib │ • Persistent cache │ • gRPC workers │

+│ • gRPC client │ • K8s manifests │ • Execute tasks │
+│ • Auto-deployment │ • Bare metal scripts│ • Report results │
+└─────────────────────────────────────────────────────────────────┘
+```
+
+### 🏗️ Hexagonal Architecture
+
+The system implements a **clean hexagonal architecture** (ports-and-adapters) with a `core/` directory structure:

+
+**Production Ready - Clean hexagonal architecture**
+
+## 🚀 Quick Start
+
+### Cold Start (Recommended for Testing)
+
+For a complete cold start from scratch (no existing containers or volumes):
+
+```bash
+# Complete cold start setup - builds everything from scratch
+./scripts/setup-cold-start.sh
+
+# This script automatically:
+# 1. Validates prerequisites (Go, Docker, ports)
+# 2. Downloads Go dependencies
+# 3. Generates protobuf files
+# 4. Creates deterministic SLURM munge key
+# 5. Starts all services with test profile
+# 6. Waits for services to be healthy
+# 7. Uploads SpiceDB schema
+# 8. Builds all binaries
+```
+
+### Integration Tests
+
+Run comprehensive integration tests across all compute and storage types:
+
+```bash
+# Run integration tests (includes cold start)
+./scripts/test/run-integration-tests.sh
+
+# This validates:
+# - SLURM clusters (both cluster 1 and cluster 2)
+# - Bare metal compute nodes
+# - Storage backends (S3/MinIO, SFTP, NFS)
+# - Credential management via SpiceDB/OpenBao
+# - Workflow execution and task dependencies
+# - Worker system and scheduler recovery
+# - Multi-runtime experiments
+```
+
+### Manual Setup
+
+Get up and running quickly with the Airavata Scheduler:
+
+```bash
+# 1. Build all binaries (scheduler, worker, CLI)
+make build
+
+# 2. Start services (PostgreSQL, SpiceDB, OpenBao)
+# Production mode (default)
+docker compose up -d postgres spicedb spicedb-postgres openbao
+
+# Or explicitly use production profile
+docker compose --profile prod up -d postgres spicedb spicedb-postgres openbao
+
+# 3. Upload SpiceDB schema
+make spicedb-schema-upload
+
+# 4. Run your first experiment
+./build/airavata-scheduler run tests/sample_experiment.yml \
+ --project my-project \
+ --compute cluster-1 \
+ --storage s3-bucket-1 \
+ --watch
+```
+
+For detailed setup instructions, see the [Quick Start Guide](docs/guides/quickstart.md).

+
+### Cold-Start Testing (Fresh Clone)
+
+For testing on a fresh clone with only Docker and Go:
+
+```bash
+# Clone and enter directory
+git clone <repo-url>
+cd airavata-scheduler
+
+# Run cold-start setup
+chmod +x scripts/*.sh
+./scripts/setup-cold-start.sh
+
+# Run all tests
+make cold-start-test
+
+# Or run individual test suites
+make test-unit
+make test-integration
+```
+
+**Prerequisites**: Docker and Go 1.21+ must be in PATH.
+
+## 🔐 Credential Management Architecture
+
+The Airavata Scheduler implements a **three-layer credential architecture** that separates authorization logic from storage for maximum security and scalability:
+
+```
+┌─────────────────────────────────────────────────────────────┐
+│ Application Layer │
+│ (Experiments, Resources, Users, Groups) │
+└────────────┬────────────────────────────────────────────────┘
+ │
+ ├──────────────────┬──────────────────┐
+ │ │ │
+┌────────────▼─────┐ ┌────────▼────────┐ ┌─────▼──────────┐
+│ PostgreSQL │ │ SpiceDB │ │ OpenBao │
+│ │ │ │ │ │
+│ Domain Data │ │ Authorization │ │ Secrets │
+│ - Users │ │ - Permissions │ │ - SSH Keys │
+│ - Groups │ │ - Ownership │ │ - Passwords │
+│ - Experiments │ │ - Sharing │ │ - Tokens │
+│ - Resources │ │ - Hierarchies │ │ (Encrypted) │
+└──────────────────┘ └─────────────────┘ └────────────────┘
+```
+
+### Key Benefits
+
+- **🔒 Separation of Concerns**: Authorization (SpiceDB) separate from secret storage (OpenBao)
+- **🛡️ Fine-grained Permissions**: Read/write/delete permissions with hierarchical group inheritance
+- **📋 Complete Audit Trail**: All operations logged across all three systems
+- **🔄 Credential Rotation**: Support for automatic key rotation with zero downtime
+- **👥 Group Management**: Groups can contain groups with transitive permission inheritance
+- **🔗 Resource Binding**: Credentials bound to specific compute/storage resources
+
+### Quick Start
+
+```bash
+# 1. Start all services including SpiceDB and OpenBao
+make docker-up
+make wait-services
+make spicedb-schema-upload
+
+# 2. Verify services
+curl -s http://localhost:8200/v1/sys/health | jq # OpenBao
+curl -s http://localhost:50052/healthz # SpiceDB
+
+# 3. Create and share credentials via API
+curl -X POST http://localhost:8080/api/v1/credentials \
+ -H "Authorization: Bearer $TOKEN" \
+ -d '{"name": "cluster-ssh", "type": "ssh_key", "data": "..."}'
+
+# 4. Share with group
+curl -X POST http://localhost:8080/api/v1/credentials/cred-123/share \
+ -H "Authorization: Bearer $TOKEN" \
+ -d '{"principal_type": "group", "principal_id": "team-1", "permission": "read"}'
+
+# 5. Bind to resource
+curl -X POST http://localhost:8080/api/v1/credentials/cred-123/bind \
+ -H "Authorization: Bearer $TOKEN" \
+ -d '{"resource_type": "compute", "resource_id": "cluster-1"}'
+```
+
+### Credential Resolution Flow
+
+When an experiment runs, the system automatically:
+
+1. **Identifies Required Resources**: Determines compute and storage resources needed
+2. **Finds Bound Credentials**: Queries SpiceDB for credentials bound to each resource
+3. **Checks User Permissions**: Verifies user has read access to each credential
+4. **Retrieves Secrets**: Decrypts credential data from OpenBao
+5. **Uses for Execution**: Provides credentials to workers for resource access

+
+## 🔧 Development
+
+### Prerequisites
+
+- Go 1.21+
+- PostgreSQL 15+
+- Docker (for testing)
+
+### Setup
+
+```bash
+# Clone repository
+git clone https://github.com/apache/airavata/scheduler.git
+cd airavata-scheduler
+
+# Install dependencies
+go mod download
+
+# Generate proto code
+make proto
+
+# Or manually
+protoc --go_out=core/dto --go-grpc_out=core/dto \
+ --go_opt=paths=source_relative \
+ --go-grpc_opt=paths=source_relative \
+ --proto_path=proto \
+ proto/*.proto
+
+# Build binaries
+make build
+
+# Setup database
+createdb airavata_scheduler
+psql airavata_scheduler < db/schema.sql
+
+# Run scheduler server
+./build/scheduler --mode=server
+
+# Run worker (in separate terminal)
+./build/worker --server-address=localhost:50051
+```
+
+### Docker Compose Profiles
+
+The project uses a single `docker-compose.yml` file with profiles to support different environments:
+
+```bash
+# Production mode (default) - Core services only
+docker compose up -d
+
+# Test mode - Full test environment with compute services
+docker compose --profile test up -d
+```
+
+**Test Profile (`test`):**
+- 2 SLURM clusters with controllers and compute nodes
+- 2 baremetal SSH servers for direct execution
+- Kubernetes-in-Docker (kind) cluster
+- Standard healthcheck intervals and timeouts
+- Used for integration testing with production-like environment
+
+### Testing
+
+```bash
+# Run all tests
+make test
+
+# Run unit tests
+make test-unit
+
+# Run integration tests
+make test-integration
+
+# Run performance tests
+make test-performance
+
+# Run tests with coverage
+make test-coverage
+
+# Run cold start test with CSV report (destroys containers/volumes)
+make cold-start-test-csv
+```
+
+#### Cold Start Testing with CSV Reports
+
+For comprehensive testing from a clean state with detailed reporting:
+
+```bash
+# Full cold start test with CSV report generation
+make cold-start-test-csv
+
+# Or run directly with options
+./scripts/test/run-cold-start-with-report.sh [OPTIONS]
+
+# Options:
+# --skip-cleanup Skip Docker cleanup
+# --skip-cold-start Skip cold start setup
+# --unit-only Run only unit tests
+# --integration-only Run only integration tests
+# --no-csv Skip CSV report generation
+```
+
+This will:
+1. **Destroy all containers and volumes** for a true cold start
+2. **Recreate environment from scratch** using `scripts/setup-cold-start.sh`
+3. **Run all test suites** (unit + integration) with JSON output
+4. **Generate CSV report** with detailed test results in `logs/cold-start-test-results-[timestamp].csv`
+
+**CSV Report Format:**
+```
+Category,Test Name,Status,Duration (s),Warnings/Notes
+Unit,TestExample,PASS,0.123,
+Integration,TestE2E,FAIL,45.67,Timeout waiting for service
+```
+
+**Status Types:**
+- `PASS`: Test passed without issues
+- `FAIL`: Test failed with errors
+- `SKIP`: Test skipped (service unavailable, etc.)
+- `PASS_WITH_WARNING`: Test passed but had warnings
+
+**Generated Files:**
+- `logs/cold-start-test-results-[timestamp].csv` - Detailed test results
+- `logs/unit-tests-[timestamp].json` - Unit test JSON output
+- `logs/integration-tests-[timestamp].json` - Integration test JSON output
+- `logs/cold-start-setup-[timestamp].log` - Cold start setup log

+## ⚠️ Known Issues & Troubleshooting
+
+### Cold Start Testing
+
+When running cold-start tests from a fresh clone, ensure:
+
+1. **SLURM Munge Key**: Run `./scripts/generate-slurm-munge-key.sh` to generate the shared authentication key
+2. **Kubernetes Cluster**: The kind-cluster service may take 2-3 minutes to fully initialize
+3. **Service Dependencies**: All services have proper health checks and startup dependencies
+
+### Service Health Checks
+
+All services now include health checks:
+- **Scheduler**: HTTP health check on `/api/v2/health`
+- **SLURM**: Munge authentication with shared key
+- **Kubernetes**: Node readiness check
+- **Storage**: Connection and availability checks
+
+### Common Issues
+
+- **SLURM Authentication Failures**: Regenerate munge key if nodes can't register
+- **Kubernetes Cluster**: Kind cluster initialization is complex and may require manual setup
+- **Port Conflicts**: Ensure ports 8080, 50051-50053, 5432, 8200, 9000-9001, 2222, 2049 are available
+

+# Building Guide
+
+## Overview
+
+This guide covers building the Airavata Scheduler system, including both the scheduler server and worker binaries, protocol buffer code generation, and deployment strategies.
+
+## Prerequisites
+
+### Required Software
+
+- **Go 1.21+**: For building Go binaries
+- **Protocol Buffers Compiler**: For generating gRPC code
+- **Make**: For build automation (optional but recommended)
+
+### Installation
+
+#### Go
+```bash
+# Install Go 1.21+
+wget https://go.dev/dl/go1.21.0.linux-amd64.tar.gz
+sudo tar -C /usr/local -xzf go1.21.0.linux-amd64.tar.gz
+export PATH=$PATH:/usr/local/go/bin
+```
+
+#### Protocol Buffers
+```bash
+# Install protoc
+wget https://github.com/protocolbuffers/protobuf/releases/download/v21.12/protoc-21.12-linux-x86_64.zip
+unzip protoc-21.12-linux-x86_64.zip -d /usr/local
+
+# Install Go plugins
+go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
+go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
+```
+
+## Build Process
+
+### Quick Start
+
+```bash
+# Clone repository
+git clone https://github.com/apache/airavata/scheduler.git
+cd airavata-scheduler
+
+# Install dependencies
+go mod download
+
+# Generate proto code
+make proto
+
+# Build both binaries
+make build
+
+# Verify build
+ls -la build/
+# Should show: scheduler, worker
+```
+
+### Build Targets
+
+The Makefile provides several build targets:
+
+```bash
+# Build both binaries
+make build
+
+# Build scheduler only
+make build-server
+
+# Build worker only
+make build-worker
+
+# Generate proto code
+make proto
+
+# Clean build artifacts
+make clean
+
+# Run tests
+make test
+
+# Run all checks (lint, test, build)
+make ci
+```
+
+### Manual Build
+
+If you prefer to build manually:
+
+```bash
+# Create build directory
+mkdir -p build
+
+# Build scheduler
+go build -o build/scheduler ./core/cmd
+
+# Build worker
+go build -o build/worker ./cmd/worker
+
+# Verify binaries
+./build/scheduler --help
+./build/worker --help
+```
+
+## Protocol Buffer Generation
+
+### Proto Files
+
+The system uses Protocol Buffers for gRPC communication:
+
+```
+proto/
+├── worker.proto # Worker service definition
+├── scheduler.proto # Scheduler service definition
+├── common.proto # Common message types
+├── data.proto # Data transfer messages
+├── experiment.proto # Experiment messages
+├── research.proto # Research messages
+└── resource.proto # Resource messages
+```
+
+### Generation Process
+
+```bash
+# Generate all proto code
+make proto
+
+# Or manually
+protoc --go_out=core/dto --go-grpc_out=core/dto \
+ --go_opt=paths=source_relative \
+ --go-grpc_opt=paths=source_relative \
+ --proto_path=proto \
+ proto/*.proto
+```
+
+### Generated Code
+
+Proto generation creates Go code in the `core/dto/` directory:
+
+```
+core/dto/
+├── worker.pb.go # Generated message types
+├── worker_grpc.pb.go # Generated gRPC service
+├── common.pb.go # Common types
+├── data.pb.go # Data transfer types
+├── experiment.pb.go # Experiment types
+├── research.pb.go # Research workflow types
+├── resource.pb.go # Resource types
+└── scheduler.pb.go # Scheduler types
+```
+
+## Binary Details
+
+### Scheduler Binary
+
+**Location**: `build/scheduler`
+**Source**: `core/cmd/main.go`
+**Purpose**: Main scheduler server with HTTP API and gRPC services
+
+```bash
+# Run scheduler
+./build/scheduler --mode=server
+
+# Available flags
+./build/scheduler --help
+```
+
+**Configuration**:
+- HTTP server port (default: 8080)
+- gRPC server port (default: 50051)
+- Database connection string
+- Worker binary configuration
+
+### Worker Binary
+
+**Location**: `build/worker`
+**Source**: `cmd/worker/main.go`
+**Purpose**: Standalone worker for task execution
+
+```bash
+# Run worker
+./build/worker --server-address=localhost:50051
+
+# Available flags
+./build/worker --help
+```
+
+**Configuration**:
+- Scheduler server address
+- Worker ID
+- Working directory
+- Heartbeat interval
+- Task timeout
+
+## Development Builds
+
+### Local Development
+
+For local development, use the development build process:
+
+```bash
+# Install development dependencies
+go mod download
+
+# Generate proto code
+make proto
+
+# Build with debug symbols
+go build -gcflags="all=-N -l" -o build/scheduler ./core/cmd
+go build -gcflags="all=-N -l" -o build/worker ./cmd/worker
+
+# Run with debug logging
+./build/scheduler --log-level=debug --mode=server
+./build/worker --log-level=debug --server-address=localhost:50051
+```
+
+### Hot Reloading
+
+For rapid development, use hot reloading:
+
+```bash
+# Install air for hot reloading
+go install github.com/cosmtrek/air@latest
+
+# Run scheduler with hot reload
+air -c .air.toml
+
+# Or use go run for simple cases
+go run ./core/cmd --mode=server
+go run ./cmd/worker --server-address=localhost:50051
+```
+
+## Production Builds
+
+### Optimized Builds
+
+For production deployment, use optimized builds:
+
+```bash
+# Build with optimizations
+CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -ldflags '-w -s' -o build/scheduler ./core/cmd
+CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -ldflags '-w -s' -o build/worker ./cmd/worker
+
+# Verify binary size
+ls -lh build/
+```
+
+### Static Builds
+
+For maximum portability, build static binaries:
+
+```bash
+# Build static binaries
+CGO_ENABLED=0 go build -ldflags '-w -s -extldflags "-static"' -o build/scheduler ./core/cmd
+CGO_ENABLED=0 go build -ldflags '-w -s -extldflags "-static"' -o build/worker ./cmd/worker
+
+# Verify static linking
+ldd build/scheduler # Should show "not a dynamic executable"
+ldd build/worker # Should show "not a dynamic executable"
+```
+
+## Cross-Compilation
+
+### Target Platforms
+
+Build for different platforms:
+
+```bash
+# Linux AMD64
+GOOS=linux GOARCH=amd64 go build -o build/scheduler-linux-amd64 ./core/cmd
+GOOS=linux GOARCH=amd64 go build -o build/worker-linux-amd64 ./cmd/worker
+
+# Linux ARM64
+GOOS=linux GOARCH=arm64 go build -o build/scheduler-linux-arm64 ./core/cmd
+GOOS=linux GOARCH=arm64 go build -o build/worker-linux-arm64 ./cmd/worker
+
+# macOS AMD64
+GOOS=darwin GOARCH=amd64 go build -o build/scheduler-darwin-amd64 ./core/cmd
+GOOS=darwin GOARCH=amd64 go build -o build/worker-darwin-amd64 ./cmd/worker
+
+# macOS ARM64 (Apple Silicon)
+GOOS=darwin GOARCH=arm64 go build -o build/scheduler-darwin-arm64 ./core/cmd
+GOOS=darwin GOARCH=arm64 go build -o build/worker-darwin-arm64 ./cmd/worker
+
+# Windows AMD64
+GOOS=windows GOARCH=amd64 go build -o build/scheduler-windows-amd64.exe ./core/cmd
+GOOS=windows GOARCH=amd64 go build -o build/worker-windows-amd64.exe ./cmd/worker
+```
+
+### Build Script
+
+Create a build script for multiple platforms:
+
+```bash
+#!/bin/bash
+# build-all.sh
+
+set -e
+
+PLATFORMS=(
+ "linux/amd64"
+ "linux/arm64"
+ "darwin/amd64"
+ "darwin/arm64"
+ "windows/amd64"
+)
+
+for platform in "${PLATFORMS[@]}"; do
+ IFS='/' read -r os arch <<< "$platform"
+
+ echo "Building for $os/$arch..."
+
+ # Build scheduler
+ GOOS=$os GOARCH=$arch go build -o "build/scheduler-$os-$arch" ./core/cmd
+
+ # Build worker
+ GOOS=$os GOARCH=$arch go build -o "build/worker-$os-$arch" ./cmd/worker
+
+ # Add .exe extension for Windows
+ if [ "$os" = "windows" ]; then
+ mv "build/scheduler-$os-$arch" "build/scheduler-$os-$arch.exe"
+ mv "build/worker-$os-$arch" "build/worker-$os-$arch.exe"
+ fi
+done
+
+echo "Build complete!"
+ls -la build/
+```
+
+## Docker Builds
+
+### Multi-Stage Dockerfile
+
+```dockerfile
+# Build stage
+FROM golang:1.21-alpine AS builder
+
+# Install dependencies
+RUN apk add --no-cache git make protoc
+
+# Set working directory
+WORKDIR /app
+
+# Copy go mod files
+COPY go.mod go.sum ./
+RUN go mod download
+
+# Copy source code
+COPY . .
+
+# Generate proto code
+RUN make proto
+
+# Build binaries
+RUN make build
+
+# Runtime stage
+FROM alpine:latest
+
+# Install runtime dependencies
+RUN apk add --no-cache ca-certificates
+
+# Copy binaries
+COPY --from=builder /app/build/scheduler /usr/local/bin/

+
+# Expose ports
+EXPOSE 8080 50051
+
+# Default command
+CMD ["scheduler", "--mode=server"]
+```
+
+### Build Docker Images
+
+```bash
+# Build scheduler image
+docker build -t airavata-scheduler:latest .
+
+# Build worker image
+docker build -f Dockerfile.worker -t airavata-worker:latest .
+
+# Build multi-arch images
+docker buildx build --platform linux/amd64,linux/arm64 -t airavata-scheduler:latest .
+```
+
+## Binary Distribution
+
+### HTTP Endpoint
+
+The scheduler provides an HTTP endpoint for worker binary distribution:
+
+```bash
+# Download worker binary
+curl -O http://scheduler:8080/api/worker-binary
+
+# Or with authentication
+curl -H "Authorization: Bearer $TOKEN" -O http://scheduler:8080/api/worker-binary
+```
+
+### Configuration
+
+Configure worker binary distribution in the scheduler:
+
+```go
+// In core/app/bootstrap.go
+config := &app.Config{
+ Worker: struct {
+ BinaryPath string `json:"binary_path"`
+ BinaryURL string `json:"binary_url"`
+ DefaultWorkingDir string `json:"default_working_dir"`
+ }{
+ BinaryPath: "./build/worker",
+ BinaryURL: "http://localhost:8080/api/worker-binary",
+ DefaultWorkingDir: "/tmp/worker",
+ },
+}
+```
+
+### Environment Variables
+
+```bash
+# Worker binary configuration
+export WORKER_BINARY_PATH="./build/worker"
+export WORKER_BINARY_URL="http://localhost:8080/api/worker-binary"
+export WORKER_WORKING_DIR="/tmp/worker"
+```
+
+## Testing Builds
+
+### Unit Tests
+
+```bash
+# Run unit tests
+make test-unit
+
+# Run with coverage
+make test-coverage
+
+# Run specific test
+go test ./tests/unit/core -v -run TestSpecific
+```
+
+### Integration Tests
+
+```bash
+# Start test services
+docker compose --profile test up -d
+
+# Run integration tests
+make test-integration
+
+# Clean up
+docker compose --profile test down
+```
+
+### Build Verification
+
+```bash
+# Verify binaries work
+./build/scheduler --help
+./build/worker --help
+
+# Test gRPC connectivity
+grpcurl -plaintext localhost:50051 list
+
+# Test HTTP API
+curl http://localhost:8080/health
+```
+
+## Troubleshooting
+
+### Common Build Issues
+
+#### Proto Generation Fails
+
+**Error**: `protoc: command not found`
+**Solution**: Install Protocol Buffers compiler
+
+```bash
+# Install protoc
+wget https://github.com/protocolbuffers/protobuf/releases/download/v21.12/protoc-21.12-linux-x86_64.zip
+unzip protoc-21.12-linux-x86_64.zip -d /usr/local
+export PATH=$PATH:/usr/local/bin
+```
+
+#### Go Modules Issues
+
+**Error**: `go: cannot find main module`
+**Solution**: Initialize Go module
+
+```bash
+# Initialize module
+go mod init github.com/apache/airavata/scheduler
+
+# Download dependencies
+go mod download
+
+# Tidy dependencies
+go mod tidy
+```
+
+#### Build Failures
+
+**Error**: `undefined: grpc.Server`
+**Solution**: Install gRPC dependencies
+
+```bash
+# Install gRPC dependencies
+go get google.golang.org/grpc@latest
+go get google.golang.org/grpc/codes@latest
+go get google.golang.org/grpc/status@latest
+```
+
+### Debug Builds
+
+#### Enable Debug Symbols
+
+```bash
+# Build with debug symbols
+go build -gcflags="all=-N -l" -o build/scheduler ./core/cmd
+go build -gcflags="all=-N -l" -o build/worker ./cmd/worker
+```
+
+#### Enable Race Detection
+
+```bash
+# Build with race detector
+go build -race -o build/scheduler ./core/cmd
+go build -race -o build/worker ./cmd/worker
+```
+
+#### Verbose Build Output
+
+```bash
+# Build with verbose output
+go build -v -o build/scheduler ./core/cmd
+go build -v -o build/worker ./cmd/worker
+```
+
+## Performance Optimization
+
+### Build Performance
+
+#### Parallel Builds
+
+```bash
+# Build with parallel jobs
+go build -p 4 -o build/scheduler ./core/cmd
+go build -p 4 -o build/worker ./cmd/worker
+```
+
+#### Build Cache
+
+```bash
+# Enable build cache
+export GOCACHE=/tmp/go-cache
+export GOMODCACHE=/tmp/go-mod-cache
+
+# Build with cache
+go build -o build/scheduler ./core/cmd
+go build -o build/worker ./cmd/worker
+```
+
+### Binary Performance
+
+#### Optimize for Size
+
+```bash
+# Build with size optimization
+go build -ldflags '-w -s' -o build/scheduler ./core/cmd
+go build -ldflags '-w -s' -o build/worker ./cmd/worker
+```
+
+#### Optimize for Speed
+
+```bash
+# Build with speed optimization
+go build -ldflags '-w -s' -o build/scheduler ./core/cmd
+go build -ldflags '-w -s' -o build/worker ./cmd/worker
+```
+
+## Best Practices
+
+### Build Process
+
+1. **Use Makefile**: Leverage build automation
+2. **Generate Proto**: Always generate proto code before building
+3. **Test Builds**: Verify binaries work after building
+4. **Clean Builds**: Use clean build directories
+5. **Version Control**: Tag releases with version numbers
+
+### Binary Management
+
+1. **Static Linking**: Use static builds for portability
+2. **Size Optimization**: Strip debug symbols for production
+3. **Cross-Compilation**: Build for target platforms
+4. **Distribution**: Use HTTP endpoints for binary distribution
+5. **Verification**: Verify binary integrity and functionality
+
+### Development Workflow
+
+1. **Hot Reloading**: Use air or similar tools for development
+2. **Debug Builds**: Use debug symbols for debugging
+3. **Test Coverage**: Maintain high test coverage
+4. **CI/CD**: Automate builds in continuous integration
+5. **Documentation**: Keep build documentation up to date

+# Credential Management Guide
+
+## Overview
+
+The Airavata Scheduler implements a secure, scalable credential management system that separates authorization logic from storage, using best-in-class open-source tools for each concern. This guide covers architecture, quick start examples, deployment, and best practices.
+
+## Architecture
+
+### Three-Layer Design

+**Purpose:** Stores non-sensitive business domain entities.
+
+**Data Stored:**
+- User profiles (name, email, UID, GID)
+- Group definitions (name, description)
+- Compute resources (name, type, endpoint)
+- Storage resources (bucket, endpoint, type)
+- Experiments and tasks (state, config, results)
+
+**What it DOES NOT store:**
+- ❌ Credentials (SSH keys, passwords, tokens)
+- ❌ Permission relationships
+- ❌ Access control lists
+
+#### 2. **SpiceDB** - Fine-Grained Authorization
+**Purpose:** Manages all permission relationships and access control.
+
+**Capabilities:**
+- Owner/reader/writer relationships for credentials
+- Hierarchical group memberships with transitive inheritance
+- Resource-to-credential bindings
+- Permission checks using Zanzibar model
+- Real-time relationship updates
+
+**Schema:**
+```zed
+definition user {}
+
+definition group {
+ relation member: user | group
+ relation parent: group
+
+ // Recursive permission inheritance through group hierarchy
+ permission is_member = member + parent->is_member
+}
+
+definition credential {
+ relation owner: user
+ relation reader: user | group#is_member
+ relation writer: user | group#is_member
+
+ // Permissions with inheritance
+ permission read = owner + reader + writer
+ permission write = owner + writer
+ permission delete = owner
+}
+
+definition compute_resource {
+ relation bound_credential: credential
+}
+
+definition storage_resource {
+ relation bound_credential: credential
+}
+```
+
+#### 3. **OpenBao** - Secure Credential Storage
+**Purpose:** Encrypts and stores sensitive credential data.
+
+**Features:**
+- KV v2 secrets engine for credential storage
+- AES-256-GCM encryption at rest
+- Transit engine for encryption key management
+- Audit logging for all operations
+- Secret versioning and rotation support
+
+**Storage Structure:**
+```
+secret/data/credentials/{credential_id}
+├── data/
+│ ├── name: "cluster-ssh-key"
+│ ├── type: "ssh_key"
+│ ├── data: "-----BEGIN OPENSSH PRIVATE KEY-----..."
+│ ├── owner_id: "user-123"
+│ └── created_at: "2024-01-15T10:30:00Z"
+├── metadata/
+│ ├── created_time: "2024-01-15T10:30:00Z"
+│ ├── current_version: 1
+│ └── versions: {...}
+```
+
+### Credential Resolution Flow
+
+When an experiment is submitted, the system follows this flow:
+
+```
+1. User submits experiment
+ ↓
+2. System identifies required resources (compute, storage)
+ ↓
+3. SpiceDB: Find credentials bound to each resource
+ ↓
+4. SpiceDB: Check user has read permission on each credential
+ ↓
+5. OpenBao: Decrypt and retrieve credential data
+ ↓
+6. System: Provide credentials to workers for execution
+```
+
+### Permission Model
+
+```
+credential owner → Full control (read/write/delete/share)
+credential reader → Read-only access (can be user or group)
+credential writer → Read + write (can be user or group)
+```
+
+**Hierarchical groups**: If Group B is a member of Group A, and a credential is shared with Group A, members of Group B automatically inherit access through the `is_member` permission.
+

+## Authentication
+
+All API endpoints require authentication using JWT tokens.
+
+### Getting an Authentication Token
+
+```javascript
+// Login endpoint
+const response = await fetch('/api/v1/auth/login', {
+ method: 'POST',
+ headers: {
+ 'Content-Type': 'application/json',
+ },
+ body: JSON.stringify({
+ username: 'your-username',
+ password: 'your-password',
+ }),
+});
+
+const { token } = await response.json();
+```
+
+### Using the Token
+
+```javascript
+// Include token in all API requests
+const apiCall = async (endpoint, options = {}) => {
+ const token = localStorage.getItem('authToken');
+
+ return fetch(endpoint, {
+ ...options,
+ headers: {
+ 'Authorization': `Bearer ${token}`,

+
+### Subscribing to Updates
+
+```javascript
+const wsManager = new WebSocketManager();
+
+// Subscribe to experiment updates
+const subscribeToExperiment = (experimentId) => {
+ const endpoint = `/ws/experiments/${experimentId}`;
+
+ wsManager.connect(endpoint, (message) => {
+ switch (message.type) {
+ case 'experiment_updated':
+ updateExperimentDisplay(message.data);
+ break;
+ case 'experiment_progress':
+ updateProgressBar(message.data);
+ break;
+ case 'task_updated':
+ updateTaskDisplay(message.data);
+ break;
+ case 'task_progress':
+ updateTaskProgress(message.data);
+ break;
+ }
+ }, (error) => {
+ console.error('WebSocket error:', error);
+ });
+
+ // Send subscription message
+ wsManager.sendMessage(endpoint, {
+ type: 'system_status',
+ data: {
+ action: 'subscribe',
+ resourceType: 'experiment',
+ resourceId: experimentId,
+ },
+ });
+};
+
+// Subscribe to user-wide updates
+const subscribeToUserUpdates = (userId) => {
+ const endpoint = '/ws/user';
+
+ wsManager.connect(endpoint, (message) => {
+ // Handle user-specific updates
+ updateUserDashboard(message.data);
+ }, (error) => {
+ console.error('WebSocket error:', error);
+ });
+};
+```
+
+## Real-time Updates
+
+### Progress Tracking
+
+```javascript
+class ProgressTracker {
+ constructor(experimentId) {
+ this.experimentId = experimentId;
+ this.progress = {
+ totalTasks: 0,
+ completedTasks: 0,
+ failedTasks: 0,
+ runningTasks: 0,
+ progressPercent: 0,
+ };
+ }
+
+ updateProgress(data) {
+ this.progress = { ...this.progress, ...data };
+ this.renderProgress();
+ }
+
+ renderProgress() {
+ const progressBar = document.getElementById('progress-bar');
+ const progressText = document.getElementById('progress-text');
+
+ progressBar.style.width = `${this.progress.progressPercent}%`;
+ progressText.textContent = `${this.progress.completedTasks}/${this.progress.totalTasks} tasks completed`;
+ }
+
+ getETA() {
+ if (this.progress.runningTasks === 0) return null;
+
+ // Simple ETA calculation
+ const avgTimePerTask = 300; // 5 minutes
+ const remainingTasks = this.progress.totalTasks - this.progress.completedTasks - this.progress.failedTasks;
+ return remainingTasks * avgTimePerTask;
+ }
+}
+```
+
+### Task Status Updates
+
+```javascript
+class TaskStatusManager {
+ constructor() {
+ this.tasks = new Map();
+ }
+
+ updateTask(taskData) {
+ this.tasks.set(taskData.taskId, taskData);
+ this.renderTask(taskData);
+ }
+
+ renderTask(taskData) {
+ const taskElement = document.getElementById(`task-${taskData.taskId}`);
+ if (taskElement) {
+ taskElement.className = `task task-${taskData.status.toLowerCase()}`;
+ taskElement.querySelector('.status').textContent = taskData.status;
+ taskElement.querySelector('.progress').textContent = `${taskData.progressPercent}%`;
+ }
+ }
+
+ getTasksByStatus(status) {
+ return Array.from(this.tasks.values()).filter(task => task.status === status);
+ }
+}
+```
+
+## State Management
+
+### Redux Store Structure
+
+```javascript
+const initialState = {
+ experiments: {
+ items: [],
+ loading: false,
+ error: null,
+ filters: {
+ projectId: null,
+ status: null,
+ dateRange: null,
+ },
+ pagination: {
+ limit: 20,
+ offset: 0,
+ total: 0,
+ },
+ },
+ currentExperiment: {
+ data: null,
+ summary: null,
+ tasks: [],
+ timeline: [],
+ loading: false,
+ error: null,
+ },
+ websocket: {
+ connections: {},
+ messages: [],
+ },
+ ui: {
+ sidebarOpen: true,
+ theme: 'light',
+ notifications: [],
+ },
+};
+```
+
+### Actions
+
+```javascript
+// Experiment actions
+export const fetchExperiments = (filters) => async (dispatch) => {
+ dispatch({ type: 'FETCH_EXPERIMENTS_START' });
+
+ try {
+ const response = await searchExperiments(filters);
+ dispatch({

+ dispatch({
+ type: 'WEBSOCKET_MESSAGE',
+ payload: message,
+ });
+ };
+
+ dispatch({
+ type: 'WEBSOCKET_CONNECTED',
+ payload: { endpoint, ws },
+ });
+};
+```
+
+## Error Handling
+
+### API Error Handling
+
+```javascript
+const handleApiError = (error) => {
+ if (error.status === 401) {
+ // Unauthorized - redirect to login
+ window.location.href = '/login';
+ } else if (error.status === 403) {
+ // Forbidden - show permission error
+ showNotification('You do not have permission to perform this action', 'error');
+ } else if (error.status === 429) {
+ // Rate limited - show retry message
+ showNotification('Rate limit exceeded. Please try again later.', 'warning');
+ } else if (error.status >= 500) {
+ // Server error - show generic error
+ showNotification('Server error. Please try again later.', 'error');
+ } else {
+ // Other errors - show specific message
+ showNotification(error.message || 'An error occurred', 'error');
+ }
+};
+
+const apiCall = async (endpoint, options = {}) => {
+ try {
+ const response = await fetch(endpoint, options);
+
+ if (!response.ok) {
+ const error = await response.json();
+ throw { status: response.status, message: error.message };
+ }
+
+ return response.json();
+ } catch (error) {
+ handleApiError(error);
+ throw error;
+ }
+};
+```
+
+### WebSocket Error Handling
+
+```javascript
+const handleWebSocketError = (error) => {
+ console.error('WebSocket error:', error);
+
+ // Show user-friendly error message
+ showNotification('Connection lost. Attempting to reconnect...', 'warning');
+
+ // Implement reconnection logic
+ setTimeout(() => {
+ reconnectWebSocket();
+ }, 5000);
+};
+```
+
+## Performance Considerations
+
+### Caching
+
+```javascript
+class ApiCache {
+ constructor(ttl = 300000) { // 5 minutes default
+ this.cache = new Map();
+ this.ttl = ttl;
+ }
+
+ get(key) {
+ const item = this.cache.get(key);
+ if (!item) return null;
+
+ if (Date.now() - item.timestamp > this.ttl) {
+ this.cache.delete(key);
+ return null;
+ }
+
+ return item.data;
+ }
+
+ set(key, data) {
+ this.cache.set(key, {
+ data,
+ timestamp: Date.now(),
+ });
+ }
+
+ clear() {
+ this.cache.clear();
+ }
+}
+
+const cache = new ApiCache();
+
+const cachedApiCall = async (endpoint, options = {}) => {
+ const cacheKey = `${endpoint}-${JSON.stringify(options)}`;
+
+ // Check cache first
+ const cached = cache.get(cacheKey);
+ if (cached) return cached;
+
+ // Make API call
+ const data = await apiCall(endpoint, options);
+
+ // Cache the result
+ cache.set(cacheKey, data);
+
+ return data;
+};
+```
+
+### Debouncing
+
+```javascript
+const debounce = (func, wait) => {
+ let timeout;
+ return function executedFunction(...args) {
+ const later = () => {
+ clearTimeout(timeout);
+ func(...args);
+ };
+ clearTimeout(timeout);
+ timeout = setTimeout(later, wait);
+ };
+};
+
+// Debounce search input
+const debouncedSearch = debounce((query) => {
+ searchExperiments({ query });
+}, 300);
+```
+
+### Virtual Scrolling
+
+```javascript
+import { FixedSizeList as List } from 'react-window';
+
+const ExperimentList = ({ experiments }) => (
+ <List
+ height={600}
+ itemCount={experiments.length}
+ itemSize={80}
+ itemData={experiments}
+ >
+ {({ index, style, data }) => (
+ <div style={style}>
+ <ExperimentItem experiment={data[index]} />
+ </div>
+ )}
+ </List>
+);
+```

+- PostgreSQL 13 or higher (or MySQL 8.0+)
+- Docker and Docker Compose (for containerized deployment)
+- SpiceDB (for fine-grained authorization)
+- OpenBao (for secure credential storage)
+- Access to compute resources (SLURM cluster, Kubernetes, or bare metal servers)
+- Access to storage resources (S3, NFS, or SFTP)
+
+## Database Setup
+
+### PostgreSQL
+
+1. **Install PostgreSQL**
+```bash
+# Ubuntu/Debian
+sudo apt-get install postgresql-13
+
+# macOS
+brew install postgresql@13
+```
+
+2. **Create Database**
+```sql
+CREATE DATABASE airavata_scheduler;
+CREATE USER airavata WITH PASSWORD 'your_secure_password';
+GRANT ALL PRIVILEGES ON DATABASE airavata_scheduler TO airavata;
+```
+
+3. **Initialize Schema**
+```bash
+psql -U airavata -d airavata_scheduler -f db/schema.sql
+```
+
+## Credential Management Services
+
+The Airavata Scheduler requires SpiceDB for authorization and OpenBao for secure credential storage.
+
+### SpiceDB Deployment
+
+SpiceDB provides fine-grained authorization using the Zanzibar model.
+
+#### Docker Compose (Recommended for Development)
+
+```yaml
+# docker-compose.yml

+cluster_addr = "https://0.0.0.0:8201"
+ui = true
+```
+
+#### Initialize OpenBao
+
+```bash
+# Initialize OpenBao (production)
+vault operator init
+
+# Enable KV v2 secrets engine
+vault secrets enable -path=secret kv-v2
+
+# Enable transit engine for encryption
+vault secrets enable transit
+
+# Create encryption key
+vault write -f transit/keys/credentials
+```
+
+### MySQL
+
+1. **Install MySQL**
+```bash
+# Ubuntu/Debian
+sudo apt-get install mysql-server
+
+# macOS
+brew install mysql
+```
+
+2. **Create Database**
+```sql
+CREATE DATABASE airavata_scheduler;
+CREATE USER 'airavata'@'localhost' IDENTIFIED BY 'your_secure_password';
+GRANT ALL PRIVILEGES ON airavata_scheduler.* TO 'airavata'@'localhost';
+FLUSH PRIVILEGES;
+```
+
+3. **Initialize Schema**
+```bash
+mysql -u airavata -p airavata_scheduler < db/schema.sql
+```
+
+## Credential Management Services Setup
+
+The Airavata Scheduler uses **OpenBao** for secure credential storage and **SpiceDB** for fine-grained authorization. These services are essential for the credential management system.
+
+### OpenBao Setup
+
+OpenBao provides secure credential storage with enterprise-grade encryption.
+
+#### Docker Compose Setup
+
+Add to your `docker-compose.yml`:
+
+```yaml
+services:
+ openbao:
+ image: openbao/openbao:1.15.0
+ container_name: openbao
+ ports:
+ - "8200:8200"
+ environment:
+ VAULT_DEV_ROOT_TOKEN_ID: "root-token-change-in-production"
+ VAULT_DEV_LISTEN_ADDRESS: "0.0.0.0:8200"
+ volumes:
+ - openbao_data:/vault/data
+ cap_add:
+ - IPC_LOCK
+ restart: unless-stopped
+
+ # For production, use a proper OpenBao configuration
+ openbao-prod:
+ image: openbao/openbao:1.15.0
+ container_name: openbao-prod
+ ports:
+ - "8200:8200"
+ environment:
+ VAULT_ADDR: "http://0.0.0.0:8200"
+ volumes:
+ - openbao_data:/vault/data
+ - ./config/openbao.hcl:/vault/config/openbao.hcl
+ cap_add:
+ - IPC_LOCK
+ restart: unless-stopped
+ command: ["vault", "server", "-config=/vault/config/openbao.hcl"]
+
+volumes:
+ openbao_data:
+```
+
+#### Production OpenBao Configuration
+
+Create `config/openbao.hcl`:
+
+```hcl
+storage "file" {
+ path = "/vault/data"
+}
+
+listener "tcp" {
+ address = "0.0.0.0:8200"
+ tls_disable = true # Enable TLS in production
+}
+
+api_addr = "http://0.0.0.0:8200"

+```
+
+#### Initialize OpenBao
+
+1. **Start OpenBao**
+```bash
+# Production mode (default)
+docker compose up -d openbao
+
+# Or explicitly use production profile
+docker compose --profile prod up -d openbao
+```
+
+2. **Initialize OpenBao (Development)**
+```bash
+# For development, OpenBao auto-initializes with root token
+export VAULT_ADDR="http://localhost:8200"
+export VAULT_TOKEN="root-token-change-in-production"
+
+# Verify OpenBao is running
+vault status
+```
+
+3. **Initialize OpenBao (Production)**
+```bash
+# Initialize OpenBao
+vault operator init -key-shares=5 -key-threshold=3
+
+# Unseal OpenBao (repeat 3 times with different keys)
+vault operator unseal <unseal-key-1>
+vault operator unseal <unseal-key-2>
+vault operator unseal <unseal-key-3>
+
+# Login with root token
+vault auth <root-token>
+```
+
+4. **Enable Required Secrets Engines**
+```bash
+# Enable KV secrets engine for credential storage
+vault secrets enable -path=credentials kv-v2
+
+# Enable transit secrets engine for encryption
+vault secrets enable -path=transit transit
+
+# Create encryption key
+vault write -f transit/keys/credentials
+```
+
+5. **Create Application Policy**
+```bash
+# Create policy for Airavata Scheduler
+vault policy write airavata-scheduler - <<EOF
+# Allow read/write access to credentials
+path "credentials/data/*" {
+ capabilities = ["create", "read", "update", "delete", "list"]
+}
+
+# Allow encryption/decryption operations
+path "transit/encrypt/credentials" {
+ capabilities = ["update"]
+}
+
+path "transit/decrypt/credentials" {
+ capabilities = ["update"]
+}
+
+# Allow key operations
+path "transit/keys/credentials" {
+ capabilities = ["read", "update"]
+}
+EOF
+
+# Create token for application
+vault token create -policy=airavata-scheduler -ttl=24h
+```
+
+### SpiceDB Setup
+
+SpiceDB provides fine-grained authorization using the Zanzibar model.
+
+#### Docker Compose Setup
+
+Add to your `docker-compose.yml`:
+
+```yaml

+
+# Update SpiceDB configuration
+command: ["spicedb", "serve", "--grpc-preshared-key", "somerandomkeyhere", "--tls-cert-path", "/certs/spicedb.crt", "--tls-key-path", "/certs/spicedb.key"]
+```
+
+3. **Network Security**
+```yaml
+# Restrict network access
+networks:
+ internal:
+ driver: bridge
+ internal: true
+
+services:
+ openbao:
+ networks:
+ - internal
+ ports:
+ - "127.0.0.1:8200:8200" # Only bind to localhost

+```
+
+## Kubernetes Deployment
+
+### Prerequisites
+
+For Kubernetes deployments, the following components are required:
+
+#### Metrics Server
+
+The Airavata Scheduler requires the Kubernetes metrics-server for worker performance monitoring. Install it using:
+
+```bash
+# Install metrics-server
+kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml
+
+# Verify installation
+kubectl get deployment metrics-server -n kube-system
+```
+
+**Note:** If metrics-server is not available, worker metrics will show as 0% but the system will continue to function normally.
+
+### Scheduler Deployment
+
+```yaml
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+ name: airavata-scheduler
+spec:
+ replicas: 2
+ selector:
+ matchLabels:

+ resources:
+ requests:
+ memory: "256Mi"
+ cpu: "500m"
+ limits:
+ memory: "1Gi"
+ cpu: "2"
+```
+
+### Service
+
+```yaml
+apiVersion: v1
+kind: Service
+metadata:
+ name: airavata-scheduler
+spec:
+ selector:
+ app: airavata-scheduler
+ ports:
+ - port: 8080
+ targetPort: 8080
+ type: LoadBalancer
+```
+
+## Production Considerations
+
+### Security
+
+1. **Use HTTPS**
+ - Enable TLS/SSL for all API endpoints
+ - Set `REQUIRE_HTTPS=true`
+ - Use proper certificates (Let's Encrypt, etc.)
+
+2. **Secure Secrets**
+ - Use secret management (Vault, AWS Secrets Manager, etc.)
+ - Rotate JWT secrets regularly
+ - Never commit secrets to version control
+
+3. **Database Security**
+ - Use strong passwords
+ - Enable SSL for database connections
+ - Restrict database access by IP
+
+4. **Network Security**
+ - Use firewalls to restrict access
+ - Deploy behind reverse proxy (Nginx, Traefik)
+ - Enable rate limiting
+
+### Performance
+
+1. **Database Optimization**
+ - Enable connection pooling
+ - Add appropriate indexes
+ - Regular VACUUM (PostgreSQL) or OPTIMIZE (MySQL)
+
+2. **Horizontal Scaling**
+ - Run multiple scheduler instances behind load balancer
+ - Scale workers based on workload
+ - Use Redis for shared state (optional)
+
+3. **Monitoring**
+ - Set up Prometheus metrics
+ - Configure log aggregation (ELK, Loki)
+ - Set up alerts for failures
+
+### Backup and Recovery
+
+1. **Database Backups**
+```bash
+# PostgreSQL
+pg_dump -U airavata airavata_scheduler > backup.sql
+
+# MySQL
+mysqldump -u airavata -p airavata_scheduler > backup.sql
+```
+
+2. **Restore**
+```bash
+# PostgreSQL
+psql -U airavata -d airavata_scheduler < backup.sql
+
+# MySQL
+mysql -u airavata -p airavata_scheduler < backup.sql
+```
+
+3. **Automated Backups**
+ - Schedule daily backups via cron
+ - Store backups in S3 or remote location
+ - Test restore procedures regularly
+
+## Monitoring
+
+### Health Checks
+
+```bash
+# API health
+curl http://localhost:8080/api/v1/health
+
+# Database connectivity
+curl http://localhost:8080/api/v1/health/db
+```
+
+### Logs
+
+```bash
+# View scheduler logs
+journalctl -u airavata-scheduler -f
+
+# View worker logs
+journalctl -u airavata-worker -f
+
+# Docker logs
+docker compose logs -f scheduler
+docker compose logs -f worker
+```
+
+### Metrics
+
+The scheduler exposes Prometheus metrics at `/metrics`:
+
+```bash
+curl http://localhost:8080/metrics
+```
+
+Key metrics:
+- `scheduler_tasks_total` - Total tasks processed
+- `scheduler_tasks_duration_seconds` - Task execution duration
+- `scheduler_workers_active` - Active workers
+- `scheduler_api_requests_total` - API request count
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Database Connection Failed**
+ - Check DATABASE_URL format
+ - Verify database is running
+ - Check network connectivity
+
+2. **Worker Not Receiving Tasks**
+ - Verify API_URL is correct
+ - Check worker is registered
+ - Verify network connectivity
+
+3. **Tasks Stuck in Queue**
+ - Check worker availability
+ - Verify compute resources are accessible
+ - Review scheduler logs
+
+### Debug Mode
+
+Enable debug logging:
+```bash
+export LOG_LEVEL=debug
+./bin/scheduler both
+```
+
+## Upgrade Guide
+
+1. **Backup Database**
+2. **Stop Services**
+3. **Deploy New Binaries**
+4. **Start Services**
+5. **Verify Health**
+
+```bash
+# Example upgrade
+systemctl stop airavata-scheduler
+pg_dump -U airavata airavata_scheduler > backup_$(date +%Y%m%d).sql
+cp bin/scheduler /opt/airavata-scheduler/bin/
+systemctl start airavata-scheduler
+systemctl status airavata-scheduler
+```
+
+**Note**: The system uses a single comprehensive schema file (`db/schema.sql`) with all production features ready for immediate deployment.

+# Development Guide
+
+## Overview
+
+This guide explains the development workflow, patterns, and best practices for the Airavata Scheduler. The system follows a clean hexagonal architecture that promotes maintainability, testability, and extensibility.
+
+**For practical setup instructions, see [Testing Guide](../tests/README.md)**
+
+## Development Philosophy
+
+### Hexagonal Architecture
+
+The Airavata Scheduler follows a hexagonal architecture (ports-and-adapters pattern):
+
+1. **Core Domain Layer** (`core/domain/`): Pure business logic with no external dependencies
+2. **Core Services Layer** (`core/service/`): Implementation of domain interfaces
+3. **Core Ports Layer** (`core/port/`): Infrastructure interfaces that services depend on
+4. **Adapters Layer** (`adapters/`): Concrete implementations of infrastructure ports
+5. **Application Layer** (`core/app/`): Dependency injection and application wiring
+
+### Key Principles
+
+- **Dependency Inversion**: Core domain depends on abstractions, not concretions
+- **Interface Segregation**: Small, focused interfaces over large, monolithic ones
+- **Single Responsibility**: Each component has one clear purpose
+- **Testability**: All components are easily testable in isolation
+- **Extensibility**: New features added through new adapters without modifying core logic
+
+## Package Structure
+
+### Core Domain Layer (`core/domain/`)
+
+Contains pure business logic with no external dependencies:
+
+```
+core/domain/
+├── interface.go # 6 core domain interfaces
+├── model.go # Domain entities (Experiment, Task, Worker, etc.)
+├── enum.go # Status enums and types (TaskStatus, WorkerStatus, etc.)
+├── value.go # Value objects
+├── error.go # Domain-specific error types
+└── event.go # Domain events for event-driven architecture
+```
+
+**Key Files:**
+- `interface.go`: Defines the 6 core domain interfaces
+- `model.go`: Contains domain entities like `Experiment`, `Task`, `Worker`
+- `enum.go`: Contains status enums like `TaskStatus`, `WorkerStatus`
+- `value.go`: Contains value objects
+- `error.go`: Domain-specific error types and constants
+- `event.go`: Domain events for event-driven architecture
+
+### Services Layer (`services/`)
+
+Implements the domain interfaces with business logic:
+
+```
+services/
+├── registry/ # ResourceRegistry implementation
+│ ├── service.go # Core resource management logic
+│ └── factory.go # Service factory
+├── vault/ # CredentialVault implementation
+│ ├── service.go # Credential management logic
+│ └── factory.go # Service factory
+├── orchestrator/ # ExperimentOrchestrator implementation
+│ ├── service.go # Experiment lifecycle management
+│ └── factory.go # Service factory
+├── scheduler/ # TaskScheduler implementation
+│ ├── service.go # Cost-based scheduling logic
+│ └── factory.go # Service factory
+├── datamover/ # DataMover implementation
+│ ├── service.go # Data staging and caching logic
+│ └── factory.go # Service factory
+└── worker/ # WorkerLifecycle implementation
+ ├── service.go # Worker management logic
+ └── factory.go # Service factory
+```
+
+**Key Patterns:**
+- Each service implements one domain interface
+- Services depend only on ports (infrastructure interfaces)
+- Factory functions for service creation with dependency injection
+- No direct dependencies on external systems
+
+### Ports Layer (`ports/`)
+
+Defines infrastructure interfaces that services depend on:
+

+ports/

+└── metrics.go # Metrics collection interface
+```
+
+**Key Patterns:**
+- Each port defines one infrastructure concern
+- Ports are implemented by adapters
+- Services depend on ports, not concrete implementations
+- Ports enable easy testing with mocks
+
+### Adapters Layer (`adapters/`)
+
+Provides concrete implementations of the ports:
+
+```
+adapters/
+├── primary/ # Inbound adapters (driving the system)
+│ └── http/ # HTTP API handlers
+│ └── handlers.go
+├── secondary/ # Outbound adapters (driven by the system)
+│ └── database/ # PostgreSQL implementation
+│ ├── adapter.go
+│ └── repositories.go
+└── external/ # External system adapters
+ ├── compute/ # SLURM, Kubernetes, Bare Metal
+ │ ├── slurm.go
+ │ ├── kubernetes.go
+ │ └── baremetal.go
+ └── storage/ # S3, NFS, SFTP
+ ├── s3.go
+ ├── nfs.go
+ └── sftp.go
+```
+
+**Key Patterns:**
+- Primary adapters drive the system (HTTP, CLI, etc.)
+- Secondary adapters are driven by the system (Database, Cache, etc.)
+- External adapters integrate with third-party systems
+- Each adapter implements one or more ports
+
+### Application Layer (`app/`)
+
+Handles dependency injection and application wiring:
+
+```
+app/
+└── bootstrap.go # Application bootstrap and dependency injection
+```
+
+**Key Patterns:**
+- Single bootstrap function that wires all dependencies
+- Configuration-driven setup
+- Clean separation of concerns
+- Easy to test and mock
+
+## Development Workflow
+
+### 1. Understanding the Codebase
+
+**Start with Domain**: Begin by understanding the core business logic:
+- `domain/interfaces.go`: The 6 core interfaces
+- `domain/models.go`: Domain entities and their relationships
+- `domain/value_objects.go`: Value objects and enums
+- `domain/errors.go`: Domain-specific error handling
+
+**Study Services**: Understand the business logic implementations:
+- `services/*/service.go`: Core business logic
+- `services/*/factory.go`: Service creation and dependency injection
+
+**Examine Ports**: Understand the infrastructure interfaces:
+- `ports/*.go`: Infrastructure interfaces that services depend on
+
+**Review Adapters**: See how external systems are integrated:
+- `adapters/primary/`: HTTP API handlers
+- `adapters/secondary/`: Database and cache implementations
+- `adapters/external/`: Third-party system integrations
+
+### 2. Adding New Features
+
+#### Adding a New Domain Service
+
+1. **Define the interface** in `domain/interfaces.go`:
+```go
+type NewService interface {
+ DoSomething(ctx context.Context, req *DoSomethingRequest) (*DoSomethingResponse, error)
+}
+```
+
+2. **Create the service implementation** in `services/newservice/`:
+```go
+// services/newservice/service.go
+type Service struct {
+ repo ports.RepositoryPort
+ cache ports.CachePort
+}
+
+func (s *Service) DoSomething(ctx context.Context, req *domain.DoSomethingRequest) (*domain.DoSomethingResponse, error) {
+ // Business logic implementation
+}
+```
+
+3. **Create the factory** in `services/newservice/factory.go`:
+```go
+func NewFactory(repo ports.RepositoryPort, cache ports.CachePort) domain.NewService {
+ return &Service{
+ repo: repo,
+ cache: cache,
+ }
+}
+```
+
+4. **Wire the service** in `app/bootstrap.go`:
+```go
+newService := newservice.NewFactory(repo, cache)
+```
+
+#### Adding a New Adapter
+
+1. **Implement the port interface**:
+```go
+// adapters/secondary/newsystem/adapter.go
+type Adapter struct {
+ client *NewSystemClient
+}
+
+func (a *Adapter) DoSomething(ctx context.Context, req *ports.DoSomethingRequest) (*ports.DoSomethingResponse, error) {
+ // External system integration
+}
+```
+
+2. **Register the adapter** in `app/bootstrap.go`:
+```go
+newSystemAdapter := newsystem.NewAdapter(config)
+```
+
+### 3. Testing Strategy
+
+#### Unit Testing
+
+Test services in isolation using mocks:
+
+```go
+func TestExperimentService_CreateExperiment(t *testing.T) {
+ // Arrange
+ mockRepo := &MockRepository{}
+ mockCache := &MockCache{}
+ service := orchestrator.NewFactory(mockRepo, mockCache)
+
+ // Act
+ result, err := service.CreateExperiment(ctx, req)
+
+ // Assert
+ assert.NoError(t, err)
+ assert.NotNil(t, result)
+}
+```
+
+#### Integration Testing
+
+Test with real infrastructure:
+
+```go
+func TestExperimentService_Integration(t *testing.T) {
+ // Setup test database
+ db := setupTestDatabase(t)
+ defer cleanupTestDatabase(t, db)
+
+ // Create real services
+ app := app.Bootstrap(testConfig)
+
+ // Test with real infrastructure
+ result, err := app.ExperimentService.CreateExperiment(ctx, req)
+ assert.NoError(t, err)
+}
+```
+
+#### Adapter Testing
+
+Test adapters with real external systems:
+
+```go
+func TestSlurmAdapter_Integration(t *testing.T) {
+ if !*integration {
+ t.Skip("Integration tests disabled")
+ }
+
+ adapter := slurm.NewAdapter(slurmConfig)
+
+ // Test with real SLURM cluster
+ result, err := adapter.SpawnWorker(ctx, 1*time.Hour)
+ assert.NoError(t, err)
+}
+```
+
+### 4. Code Organization
+
+#### File Naming Conventions
+
+- **Services**: `service.go` for implementation, `factory.go` for creation
+- **Adapters**: `adapter.go` for main implementation, `repositories.go` for data access
+- **Tests**: `*_test.go` with descriptive names
+- **Configuration**: `config.go` or embedded in bootstrap
+
+#### Import Organization
+
+```go
+import (
+ // Standard library
+ "context"
+ "fmt"
+
+ // Third-party packages
+ "github.com/gorilla/mux"
+ "gorm.io/gorm"
+
+ // Internal packages
+ "github.com/apache/airavata/scheduler/domain"
+ "github.com/apache/airavata/scheduler/ports"
+ "github.com/apache/airavata/scheduler/services/orchestrator"
+)
+```
+
+#### Error Handling
+
+Use domain-specific errors:
+
+```go
+// In domain/errors.go
+var (
+ ErrExperimentNotFound = errors.New("experiment not found")
+ ErrInvalidParameter = errors.New("invalid parameter")
+)
+
+// In service
+func (s *Service) GetExperiment(ctx context.Context, id string) (*domain.Experiment, error) {
+ experiment, err := s.repo.GetExperimentByID(ctx, id)
+ if err != nil {
+ if errors.Is(err, gorm.ErrRecordNotFound) {
+ return nil, domain.ErrExperimentNotFound
+ }
+ return nil, fmt.Errorf("failed to get experiment: %w", err)
+ }
+ return experiment, nil
+}
+```
+
+### 5. Performance Considerations
+
+#### Database Optimization
+
+- Use connection pooling
+- Implement proper indexing
+- Use batch operations for bulk data
+- Monitor query performance
+

+
+## Common Patterns
+
+### Service Pattern
+
+```go
+type Service struct {
+ repo ports.RepositoryPort
+ cache ports.CachePort
+ events ports.EventPort
+}
+
+func (s *Service) DoSomething(ctx context.Context, req *domain.Request) (*domain.Response, error) {
+ // 1. Validate input
+ if err := s.validateRequest(req); err != nil {
+ return nil, err
+ }
+
+ // 2. Check cache
+ if cached, err := s.cache.Get(ctx, req.ID); err == nil {
+ return cached, nil
+ }
+
+ // 3. Business logic
+ result, err := s.repo.DoSomething(ctx, req)
+ if err != nil {
+ return nil, err
+ }
+
+ // 4. Cache result
+ s.cache.Set(ctx, req.ID, result, time.Hour)
+
+ // 5. Publish event
+ s.events.Publish(ctx, &domain.Event{Type: "SomethingDone", Data: result})
+
+ return result, nil
+}
+```
+
+### Adapter Pattern
+
+```go
+type Adapter struct {
+ client *ExternalClient
+ config *Config
+}
+
+func (a *Adapter) DoSomething(ctx context.Context, req *ports.Request) (*ports.Response, error) {
+ // 1. Transform request
+ externalReq := a.transformRequest(req)
+
+ // 2. Call external system
+ externalResp, err := a.client.DoSomething(ctx, externalReq)
+ if err != nil {
+ return nil, fmt.Errorf("external system error: %w", err)
+ }
+
+ // 3. Transform response
+ response := a.transformResponse(externalResp)
+
+ return response, nil
+}
+```
+
+### Factory Pattern
+
+```go
+func NewFactory(repo ports.RepositoryPort, cache ports.CachePort, events ports.EventPort) domain.Service {
+ return &Service{
+ repo: repo,
+ cache: cache,
+ events: events,
+ }
+}
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Import cycles**: Ensure domain doesn't import from services or adapters
+2. **Missing interfaces**: Define ports for all external dependencies
+3. **Test failures**: Check that mocks implement the correct interfaces
+4. **Performance issues**: Profile and optimize database queries and caching
+
+### Debugging Tips
+
+1. **Use structured logging** to trace request flows
+2. **Enable debug mode** for detailed error information
+3. **Use distributed tracing** to track external system calls
+4. **Monitor metrics** to identify performance bottlenecks
+
+### Getting Help
+
+1. **Check the logs** for error messages and stack traces
+2. **Review the architecture** to understand the flow
+3. **Test in isolation** to identify the problematic component
+4. **Use the test suite** to verify expected behavior
+
+## CLI Development
+
+The Airavata Scheduler includes a comprehensive command-line interface built with Cobra.
+
+### CLI Architecture
+
+The CLI follows a modular structure with separate command groups:
+
+```
+cmd/cli/
+├── main.go # Root command and experiment management
+├── auth.go # Authentication commands
+├── user.go # User profile and account management
+├── resources.go # Resource management (compute, storage, credentials)
+├── data.go # Data upload/download commands
+├── project.go # Project management commands
+└── config.go # Configuration management
+```
+
+### Adding New Commands
+
+To add a new command group:
+
+1. **Create command group function**:
+```go
+func createNewCommands() *cobra.Command {
+ newCmd := &cobra.Command{
+ Use: "new",
+ Short: "New command group",
+ Long: "Description of new command group",
+ }
+
+ // Add subcommands
+ newCmd.AddCommand(createSubCommand())
+
+ return newCmd
+}
+```
+
+2. **Add to root command** in `main.go`:
+```go
+rootCmd.AddCommand(createNewCommands())
+```
+
+3. **Implement command functions**:
+```go
+func executeNewCommand(cmd *cobra.Command, args []string) error {
+ // Command implementation
+ return nil
+}
+```
+
+### CLI Patterns
+
+#### Authentication Check
+All commands should check authentication:
+```go
+configManager := NewConfigManager()
+if !configManager.IsAuthenticated() {
+ return fmt.Errorf("not authenticated - run 'airavata auth login' first")
+}
+```
+
+#### API Communication
+Use consistent HTTP client patterns:
+```go
+ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
+defer cancel()
+
+req, err := http.NewRequestWithContext(ctx, "GET", url, nil)
+if err != nil {
+ return fmt.Errorf("failed to create request: %w", err)
+}
+
+req.Header.Set("Authorization", "Bearer "+token)
+```
+
+#### Error Handling
+Provide clear, actionable error messages:
+```go
+if resp.StatusCode != http.StatusOK {
+ return fmt.Errorf("failed to %s: %s", operation, string(body))
+}
+```
+
+#### Progress Feedback
+Show progress for long-running operations:
+```go
+fmt.Printf("📤 Uploading %s...\n", filename)
+// ... operation ...
+fmt.Printf("✅ Upload completed successfully!\n")
+```
+
+### CLI Testing
+
+Test CLI commands with:
+```bash
+# Test command help
+./bin/airavata --help
+./bin/airavata experiment --help
+
+# Test command execution
+./bin/airavata auth status
+./bin/airavata resource compute list
+```
+
+### CLI Documentation
+
+Update documentation when adding new commands:
+1. Add to `docs/reference/cli.md`
+2. Include examples and usage patterns
+3. Update README.md if adding major features
+
+## Building the Worker Binary
+
+### Proto Code Generation
+
+The system uses Protocol Buffers for gRPC communication. Generate proto code before building:
+
+```bash
+# Install protoc and Go plugins
+go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
+go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
+
+# Generate proto code
+make proto
+
+# Or manually
+protoc --go_out=core/dto --go-grpc_out=core/dto \
+ --go_opt=paths=source_relative \
+ --go-grpc_opt=paths=source_relative \
+ --proto_path=proto \
+ proto/*.proto
+```
+
+### SLURM Munge Key Generation
+
+For integration testing with SLURM clusters, the system uses a deterministic munge key to ensure reproducible authentication across all SLURM nodes:
+
+```bash
+# Generate deterministic munge key for SLURM clusters
+./scripts/generate-slurm-munge-key.sh
+
+# This creates tests/docker/slurm/shared-munge.key with:
+# - Deterministic content based on fixed seed "airavata-munge-test-seed-v1"
+# - 1024-byte binary key generated from SHA256 hashes
+# - Same key used across all SLURM containers for consistent authentication
+```
+
+**Key Features:**
+- **Deterministic**: Same key generated every time from fixed seed
+- **Shared**: All SLURM containers (controllers and nodes) use identical key
+- **Secure**: 1024-byte binary key suitable for production use
+- **Reproducible**: Enables consistent cold-start testing
+
+**Verification:**
+```bash
+# Verify all containers share the same munge key
+docker exec airavata-scheduler-slurm-cluster-01-1 sha256sum /etc/munge/munge.key
+docker exec airavata-scheduler-slurm-cluster-02-1 sha256sum /etc/munge/munge.key
+docker exec airavata-scheduler-slurm-node-01-01-1 sha256sum /etc/munge/munge.key
+docker exec airavata-scheduler-slurm-node-02-01-1 sha256sum /etc/munge/munge.key
+# All should output identical SHA256 hash
+```
+
+### Building Both Binaries
+
+```bash
+# Build both scheduler and worker
+make build
+
+# Or build individually
+make build-server # Builds build/scheduler
+make build-worker # Builds build/worker
+
+# Verify binaries
+./build/scheduler --help
+./build/worker --help
+```
+
+### Development Workflow
+
+```bash
+# 1. Generate proto code
+make proto
+
+# 2. Build binaries
+make build
+
+# 3. Run scheduler
+./build/scheduler --mode=server
+
+# 4. Run worker (in separate terminal)
+./build/worker --server-address=localhost:50051
+```
+
+## Testing Worker Communication
+
+### Unit Tests
+
+```bash
+# Test worker gRPC client
+go test ./cmd/worker -v
+
+# Test scheduler gRPC server
+go test ./adapters -v -run TestWorkerService

+
+### Integration Tests
+
+```bash
+# Start test services
+docker compose --profile test up -d
+
+# Test worker integration
+go test ./tests/integration -v -run TestWorkerIntegration

+```bash
+# Test gRPC connectivity
+grpcurl -plaintext localhost:50051 list
+grpcurl -plaintext localhost:50051 worker.WorkerService/ListWorkers
+
+# Test worker registration
+./build/worker --server-address=localhost:50051 --worker-id=test-worker-1

+ --endpoint localhost:50051 \
+ --token "somerandomkeyhere" \
+ --insecure \
+ --filter 'group:YOUR_GROUP_ID'
+```
+
+#### Secret Not Found Errors
+
+```bash
+# List all secrets
+vault kv list secret/credentials/
+
+# Check secret metadata
+vault kv metadata get secret/credentials/YOUR_CRED_ID
+
+# Verify token has correct policy

+```
+
+## Performance Testing
+
+### Load Testing Credentials
+
+```bash
+# Install k6
+brew install k6
+
+# Run load test
+k6 run tests/performance/credential_load_test.js
+
+# Test concurrent permission checks
+k6 run tests/performance/permission_check_load_test.js
+```
+
+### Profiling
+
+```bash
+# Enable pprof in scheduler
+./build/scheduler --mode=server --pprof=true
+
+# Capture CPU profile
+go tool pprof http://localhost:6060/debug/pprof/profile?seconds=30
+
+# Capture memory profile

+# Quick Start Guide
+
+This guide will get you up and running with the Airavata Scheduler in minutes.
+
+## Prerequisites
+
+- Go 1.21 or higher
+- Docker and Docker Compose
+- PostgreSQL 13+ (or use Docker)
+- Access to compute resources (SLURM, Kubernetes, or bare metal)
+- Access to storage resources (S3, NFS, or SFTP)
+
+## 1. Build Binaries
+
+```bash
+# Clone the repository
+git clone https://github.com/apache/airavata/scheduler.git
+cd airavata-scheduler
+
+# Build all binaries (scheduler, worker, CLI)
+make build
+
+# Or build individually
+make build-server # Builds bin/scheduler
+make build-worker # Builds bin/worker
+make build-cli # Builds bin/airavata
+```
+
+The CLI binary will be available at `./bin/airavata` and provides complete system management capabilities.
+
+## 2. Start Services
+
+### Cold Start (Recommended for Testing)
+
+For a complete cold start from scratch (no existing containers or volumes):
+
+```bash
+# Complete cold start setup - builds everything from scratch
+./scripts/setup-cold-start.sh
+
+# This script automatically:
+# 1. Validates prerequisites (Go, Docker, ports)
+# 2. Downloads Go dependencies
+# 3. Generates protobuf files
+# 4. Creates deterministic SLURM munge key
+# 5. Starts all services with test profile
+# 6. Waits for services to be healthy
+# 7. Uploads SpiceDB schema
+# 8. Builds all binaries
+```
+
+### Manual Service Start
+
+```bash
+# Start all required services (PostgreSQL, SpiceDB, OpenBao)
+docker compose up -d postgres spicedb spicedb-postgres openbao
+
+# Wait for services to be healthy
+make wait-services
+
+# Upload SpiceDB authorization schema
+make spicedb-schema-upload
+
+# Verify services are running
+curl -s http://localhost:8200/v1/sys/health | jq # OpenBao
+curl -s http://localhost:50052/healthz # SpiceDB
+```
+
+### Test Environment (Full Stack)
+
+For integration testing with compute and storage resources:
+
+```bash
+# Start all services including SLURM clusters, bare metal nodes, and storage
+docker compose --profile test up -d
+
+# Wait for all services to be healthy
+./scripts/wait-for-services.sh
+
+# Run integration tests
+./scripts/test/run-integration-tests.sh
+```
+
+## 3. Bootstrap Application
+
+```go
+package main
+
+import (
+ "log"
+ "github.com/apache/airavata/scheduler/core/app"
+)
+
+func main() {
+ config := &app.Config{
+ Database: struct {
+ DSN string `json:"dsn"`
+ }{
+ DSN: "postgres://user:password@localhost:5432/airavata?sslmode=disable",
+ },
+ Server: struct {
+ Host string `json:"host"`
+ Port int `json:"port"`
+ }{
+ Host: "0.0.0.0",
+ Port: 8080,
+ },
+ Worker: struct {
+ BinaryPath string `json:"binary_path"`
+ BinaryURL string `json:"binary_url"`
+ DefaultWorkingDir string `json:"default_working_dir"`
+ }{
+ BinaryPath: "./build/worker",
+ BinaryURL: "http://localhost:8080/api/worker-binary",
+ DefaultWorkingDir: "/tmp/worker",
+ },
+ }
+
+ application, err := app.Bootstrap(config)
+ if err != nil {
+ log.Fatal(err)
+ }
+
+ application.Start()
+}
+```
+
+## 4. Register Resources
+
+### Register Compute Resource
+
+```go
+// Register SLURM cluster
+computeReq := &domain.RegisterComputeResourceRequest{
+ Name: "SLURM Cluster",
+ Type: "slurm",
+ Endpoint: "slurm.example.com:22",
+ Credentials: "credential_id",
+}
+
+response, err := resourceRegistry.RegisterComputeResource(ctx, computeReq)
+```
+
+### Register Storage Resource
+
+```go
+// Register S3 bucket
+storageReq := &domain.RegisterStorageResourceRequest{
+ Name: "S3 Bucket",
+ Type: "s3",
+ Endpoint: "s3://my-bucket",
+ Credentials: "credential_id",
+}
+
+response, err := resourceRegistry.RegisterStorageResource(ctx, storageReq)
+```
+
+## 5. Using the Command Line Interface
+
+The Airavata Scheduler includes a comprehensive CLI (`airavata`) for complete system management.
+
+### Authentication
+
+```bash
+# Login to the scheduler
+./bin/airavata auth login

+```
+
+### Experiment Management
+
+```bash
+# Run experiment
+./bin/airavata experiment run experiment.yml --project proj-123 --compute slurm-1
+
+# Monitor experiment
+./bin/airavata experiment watch exp-456
+
+# Check experiment status
+./bin/airavata experiment status exp-456
+
+# List all experiments
+./bin/airavata experiment list
+
+# View experiment logs
+./bin/airavata experiment logs exp-456
+
+# Cancel running experiment

+
+# Download specific file
+./bin/airavata experiment download exp-456 --file task-789/output.txt --output ./output.txt
+```
+
+### Complete Workflow Example
+
+```bash
+# 1. Authenticate
+./bin/airavata auth login
+
+# 2. Create project
+./bin/airavata project create
+
+# 3. Upload input data
+./bin/airavata data upload input.dat minio-storage:/experiments/input.dat

+```
+
+For complete CLI documentation, see [CLI Reference](../reference/cli.md).
+
+## 6. Run Your First Experiment
+
+### Using the CLI (Recommended)
+
+```bash
+# Run experiment from YAML file with automatic credential resolution
+./build/airavata-scheduler run tests/sample_experiment.yml \
+ --project my-project \
+ --compute cluster-1 \
+ --storage s3-bucket-1 \
+ --watch
+
+# The CLI automatically:
+# 1. Resolves credentials bound to compute/storage resources
+# 2. Checks user permissions via SpiceDB
+# 3. Retrieves secrets from OpenBao
+# 4. Executes experiment with proper credentials
+# 5. Shows real-time progress
+```
+
+### Using the API
+
+```go
+// Create experiment with dynamic template
+experimentReq := &domain.CreateExperimentRequest{
+ Name: "Parameter Sweep",
+ Description: "Testing different parameters",
+ Template: "python script.py --param {{.param_value}}",
+ Parameters: []domain.ParameterSet{
+ {Values: map[string]interface{}{"param_value": "1"}},
+ {Values: map[string]interface{}{"param_value": "2"}},
+ {Values: map[string]interface{}{"param_value": "3"}},
+ },
+}
+
+experiment, err := experimentOrch.CreateExperiment(ctx, experimentReq)
+
+// Submit for execution (credentials resolved automatically)
+resp, err := experimentOrch.SubmitExperiment(ctx, &domain.SubmitExperimentRequest{
+ ExperimentID: experiment.ID,
+})
+```
+
+## 6. Credential Management
+
+### Create and Share Credentials
+
+```bash
+# Create SSH key credential
+curl -X POST http://localhost:8080/api/v1/credentials \
+ -H "Authorization: Bearer $TOKEN" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "name": "cluster-ssh-key",
+ "type": "ssh_key",
+ "data": "-----BEGIN OPENSSH PRIVATE KEY-----\n...",
+ "description": "SSH key for cluster access"
+ }'
+
+# Share credential with group
+curl -X POST http://localhost:8080/api/v1/credentials/cred-123/share \
+ -H "Authorization: Bearer $TOKEN" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "principal_type": "group",
+ "principal_id": "team-1",
+ "permission": "read"
+ }'
+
+# Bind credential to resource
+curl -X POST http://localhost:8080/api/v1/credentials/cred-123/bind \
+ -H "Authorization: Bearer $TOKEN" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "resource_type": "compute",
+ "resource_id": "cluster-1"
+ }'
+```
+
+## 7. Monitor Progress
+
+### CLI Real-time Monitoring
+
+```bash
+# Watch experiment progress in real-time
+./build/airavata-scheduler run experiment.yml --watch
+
+# Check experiment status
+./build/airavata-scheduler experiment status <experiment-id>
+```
+
+### API Monitoring
+
+```go
+// Get experiment status
+resp, err := orchestrator.GetExperiment(ctx, &domain.GetExperimentRequest{
+ ExperimentID: experimentID,
+ IncludeTasks: true,
+})
+
+// Monitor task progress
+for _, task := range resp.Experiment.Tasks {
+ fmt.Printf("Task %s: %s\n", task.ID, task.Status)
+}
+```

+# Airavata Scheduler Architecture
+
+## Overview
+
+The Airavata Scheduler is a distributed task execution system designed for scientific computing experiments. It implements a clean hexagonal architecture (ports-and-adapters pattern) that provides cost-based scheduling, intelligent resource allocation, and comprehensive data management with a focus on clarity, reliability, and performance.
+
+## Hexagonal Architecture
+
+The system follows the hexagonal architecture pattern, also known as ports-and-adapters, which provides:
+
+- **Clear separation of concerns**: Business logic is isolated from infrastructure
+- **Testability**: Core domain can be tested without external dependencies
+- **Flexibility**: Easy to swap implementations or add new adapters
+- **Maintainability**: Changes to external systems don't affect core business logic
+
+## Credential Management Architecture
+
+The Airavata Scheduler implements a **three-layer credential architecture** that separates authorization logic from storage for maximum security and scalability:
+
+### System Components
+
+```
+┌─────────────────────────────────────────────────────────────┐
+│ Application Layer │
+│ (Experiments, Resources, Users, Groups) │
+└────────────┬────────────────────────────────────────────────┘
+ │
+ ├──────────────────┬──────────────────┐
+ │ │ │
+┌────────────▼─────┐ ┌────────▼────────┐ ┌─────▼──────────┐
+│ PostgreSQL │ │ SpiceDB │ │ OpenBao │
+│ │ │ │ │ │
+│ Domain Data │ │ Authorization │ │ Secrets │
+│ - Users │ │ - Permissions │ │ - SSH Keys │
+│ - Groups │ │ - Ownership │ │ - Passwords │
+│ - Experiments │ │ - Sharing │ │ - Tokens │
+│ - Resources │ │ - Hierarchies │ │ (Encrypted) │
+└──────────────────┘ └─────────────────┘ └────────────────┘
+```
+
+### Component Responsibilities
+
+#### PostgreSQL - Domain Entity Storage
+- **Purpose**: Stores non-sensitive business domain entities
+- **Data**: Users, groups, experiments, resources, tasks
+- **What it DOES NOT store**: Credentials, permissions, or access control lists
+
+#### SpiceDB - Fine-Grained Authorization
+- **Purpose**: Manages all permission relationships and access control
+- **Capabilities**: Owner/reader/writer relationships, hierarchical groups, resource bindings
+- **Schema**: Zanzibar model with transitive permission inheritance
+
+#### OpenBao - Secure Credential Storage
+- **Purpose**: Encrypts and stores sensitive credential data
+- **Features**: KV v2 secrets engine, AES-256-GCM encryption, audit logging
+- **Storage**: Encrypted SSH keys, passwords, API tokens
+
+### Credential Resolution Flow
+
+When an experiment is submitted, the system follows this flow:
+
+```
+1. User submits experiment
+ ↓
+2. System identifies required resources (compute, storage)
+ ↓
+3. SpiceDB: Find credentials bound to each resource
+ ↓
+4. SpiceDB: Check user has read permission on each credential
+ ↓
+5. OpenBao: Decrypt and retrieve credential data
+ ↓
+6. System: Provide credentials to workers for execution
+```
+
+### Permission Model
+
+```
+credential owner → Full control (read/write/delete/share)
+credential reader → Read-only access (can be user or group)
+credential writer → Read + write (can be user or group)
+```
+
+**Hierarchical groups**: If Group B is a member of Group A, and a credential is shared with Group A, members of Group B automatically inherit access through the `is_member` permission.

+
+### Key Components
+
+#### 1. VaultService (Core Business Logic)
+The `VaultService` implements the `CredentialVault` domain interface and provides the main credential management functionality:
+
+**Core Operations:**
+- `StoreCredential()` - Securely store credentials with encryption

+type VaultPort interface {
+ StoreCredential(ctx context.Context, id string, credentialType CredentialType, data []byte, ownerID string) (string, error)
+ RetrieveCredential(ctx context.Context, id string, userID string) (*Credential, error)
+ UpdateCredential(ctx context.Context, id string, data []byte, userID string) error
+ DeleteCredential(ctx context.Context, id string, userID string) error
+ ListCredentials(ctx context.Context, userID string) ([]*Credential, error)
+}
+```
+
+#### 3. AuthorizationPort Interface
+Defines the contract for authorization operations:
+
+```go
+type AuthorizationPort interface {
+ CheckPermission(ctx context.Context, userID, objectID, objectType, permission string) (bool, error)
+ ShareCredential(ctx context.Context, credentialID, userID, objectType, permission string) error

+
+### Credential Lifecycle
+
+#### 1. Credential Creation
+```
+User Request → VaultService → OpenBao (Store) → SpiceDB (Owner Permission)
+ ↓ ↓ ↓ ↓
+ Validation → Business Logic → Encryption → Authorization Setup
+```
+
+#### 2. Credential Access
+```
+User Request → VaultService → SpiceDB (Check Permission) → OpenBao (Retrieve)
+ ↓ ↓ ↓ ↓
+ Validation → Business Logic → Authorization Check → Decryption
+```
+
+#### 3. Credential Sharing
+```
+User Request → VaultService → SpiceDB (Add Permission) → Audit Log
+ ↓ ↓ ↓ ↓
+ Validation → Business Logic → Permission Update → Compliance
+```
+
+### Security Model
+
+#### Encryption at Rest
+- **OpenBao Transit Engine**: All credentials encrypted with AES-256-GCM
+- **Key Derivation**: Argon2id for memory-hard key derivation
+- **Envelope Encryption**: Separate encryption keys for each credential
+- **Key Rotation**: Support for automatic key rotation
+
+#### Access Control
+- **Relationship-Based**: SpiceDB's Zanzibar model for fine-grained permissions
+- **Hierarchical Groups**: Support for nested group memberships
+- **Resource Binding**: Credentials can be bound to specific compute/storage resources
+- **Permission Inheritance**: Group permissions inherited by members
+
+#### Audit and Compliance
+- **Complete Audit Trail**: All credential operations logged
+- **Access Tracking**: Who accessed what credentials when
+- **Compliance Reporting**: Built-in reports for security audits
+- **Retention Policies**: Configurable audit log retention
+
+### Integration with Resource Management
+
+#### Credential-Resource Binding
+Credentials can be bound to specific resources for enhanced security:
+
+```go
+// Bind credential to compute resource
+err := authz.BindCredentialToResource(ctx, credentialID, resourceID, "compute_resource")
+
+// Get usable credentials for a resource
+credentials, err := authz.GetUsableCredentialsForResource(ctx, userID, resourceID, "compute_resource", "read")
+```
+
+#### Resource-Specific Access
+- **Compute Resources**: Credentials bound to specific SLURM clusters, Kubernetes namespaces, or bare metal systems
+- **Storage Resources**: Credentials bound to specific S3 buckets, NFS mounts, or SFTP servers
+- **Dynamic Binding**: Credentials can be dynamically bound/unbound from resources
+
+### Performance and Scalability
+
+#### Caching Strategy
+- **Permission Caching**: SpiceDB permission checks cached for performance
+- **Credential Caching**: Frequently accessed credentials cached in memory
+- **Cache Invalidation**: Automatic cache invalidation on permission changes
+
+#### High Availability
+- **OpenBao Clustering**: Multi-node OpenBao deployment for HA
+- **SpiceDB Clustering**: Distributed SpiceDB deployment for scalability
+- **Failover Support**: Automatic failover to backup services
+
+#### Monitoring and Observability
+- **Metrics Collection**: Comprehensive metrics for credential operations
+- **Health Checks**: Service health monitoring for OpenBao and SpiceDB
+- **Alerting**: Proactive alerting for security events and service issues
+
+### Migration from Legacy System
+
+The new credential management system replaces the previous in-memory ACL system with:
+
+#### Removed Components
+- **In-memory ACL maps**: Replaced with SpiceDB relationships
+- **Database ACL tables**: Simplified to basic credential metadata
+- **Custom encryption**: Replaced with OpenBao's enterprise-grade encryption
+
+#### Enhanced Features
+- **Enterprise Security**: OpenBao provides industry-standard security
+- **Fine-grained Permissions**: SpiceDB enables complex permission models
+- **Audit Compliance**: Built-in audit trails for regulatory compliance
+- **Scalability**: Distributed architecture supports large-scale deployments
+
+This credential management architecture provides a robust, secure, and scalable foundation for managing sensitive credentials in a distributed scientific computing environment.
+
+## gRPC Worker System
+
+The Airavata Scheduler uses a distributed worker architecture where standalone worker binaries communicate with the scheduler via gRPC. This design enables:
+
+- **Scalability**: Workers can be deployed across multiple compute resources
+- **Isolation**: Worker failures don't affect the scheduler
+- **Flexibility**: Workers can be deployed on different platforms (SLURM, Kubernetes, Bare Metal)
+- **Efficiency**: Direct binary deployment without container overhead
+
+### Worker Architecture

+│ ├── Data Staging │
+│ ├── Command Execution │
+│ └── Result Collection │
+└─────────────────────────────────────────────────────────────────┘
+```
+
+### Worker Lifecycle
+
+1. **Deployment**: Worker binary is deployed to compute resource via script generation
+2. **Registration**: Worker connects to scheduler gRPC server
+3. **Task Polling**: Worker continuously polls for available tasks
+4. **Task Execution**: Worker executes assigned tasks with proper isolation
+5. **Status Reporting**: Worker reports progress and completion status
+6. **Cleanup**: Worker cleans up resources and reports final status
+
+### Script Generation for Compute Resources
+
+The system generates runtime-specific scripts for deploying workers:
+
+#### SLURM Scripts
+```bash
+#!/bin/bash
+#SBATCH --job-name=worker_${WORKER_ID}
+#SBATCH --time=${WALLTIME}
+#SBATCH --cpus-per-task=${CPU_CORES}
+#SBATCH --mem=${MEMORY_MB}
+
+# Download and execute worker binary
+curl -L "${WORKER_BINARY_URL}" -o worker
+chmod +x worker
+./worker --server-address=${SERVER_ADDRESS}:${SERVER_PORT}
+```
+
+#### Kubernetes Manifests
+```yaml
+apiVersion: batch/v1
+kind: Job
+metadata:
+ name: worker-${WORKER_ID}
+spec:
+ template:
+ spec:
+ containers:
+ - name: worker
+ image: worker-binary:latest
+ command: ["./worker"]
+ args: ["--server-address=${SERVER_ADDRESS}:${SERVER_PORT}"]
+ resources:
+ requests:
+ cpu: "${CPU_CORES}"
+ memory: "${MEMORY_MB}Mi"
+```
+
+#### Bare Metal Scripts
+```bash
+#!/bin/bash
+# Download and execute worker binary
+curl -L "${WORKER_BINARY_URL}" -o worker
+chmod +x worker
+timeout ${WALLTIME_SECONDS} ./worker --server-address=${SERVER_ADDRESS}:${SERVER_PORT}
+```
+
+### Worker Configuration
+
+Workers are configured through environment variables and command-line flags:
+
+```bash
+# Required configuration
+--server-address=localhost:50051 # Scheduler gRPC server address
+--worker-id=worker_12345 # Unique worker identifier
+--working-dir=/tmp/worker # Working directory for tasks
+
+# Optional configuration
+--heartbeat-interval=30s # Heartbeat frequency
+--task-timeout=1h # Maximum task execution time
+--log-level=info # Logging level
+```
+
+### Task Execution Flow
+
+1. **Task Assignment**: Scheduler assigns task to available worker
+2. **Data Staging**: Required input files are staged to worker
+3. **Script Generation**: Task-specific execution script is generated
+4. **Execution**: Worker executes the task in isolated environment
+5. **Monitoring**: Scheduler monitors progress via heartbeats
+6. **Result Collection**: Output files are collected from worker
+7. **Cleanup**: Worker cleans up temporary files and reports completion
+

+
+## Key Design Principles
+
+### 1. Dependency Inversion
+- High-level modules don't depend on low-level modules
+- Both depend on abstractions (interfaces)
+- Abstractions don't depend on details
+
+### 2. Single Responsibility
+- Each service has one clear purpose
+- Each adapter handles one external system
+- Each port defines one infrastructure concern
+
+### 3. Interface Segregation
+- Clients depend only on interfaces they use
+- Small, focused interfaces over large, monolithic ones
+- Clear separation between different concerns
+
+### 4. Open/Closed Principle
+- Open for extension (new adapters)
+- Closed for modification (core domain logic)
+- New features added through new adapters
+
+### 5. Testability
+- Core domain can be tested in isolation
+- Adapters can be mocked for testing
+- Clear boundaries enable comprehensive testing
+
+## Technology Integration
+
+### Database Layer
+- **PostgreSQL 15+** with GORM v2 ORM
+- **Single schema file** approach (no migrations)
+- **Repository pattern** for data access
+- **Connection pooling** and transaction management
+
+### Caching Layer

+- **Audit logging** for compliance
+
+### Monitoring

+
+## Scalability Considerations
+
+### Horizontal Scaling

+- **Load balancing** across multiple instances
+- **Database sharding** for large datasets
+- **Caching strategies** to reduce database load
+
+### Performance Optimization

+- **Resource optimization** algorithms
+
+### Reliability
+- **Circuit breakers** for external system failures

+
+## Deployment Architecture
+
+### Container Deployment
+```yaml
+services:
+ scheduler:
+ image: airavata-scheduler:latest

+## Environment Variables
+
+The CLI respects the following environment variables:
+
+- `AIRAVATA_SERVER_URL` - Default server URL
+- `AIRAVATA_CONFIG_DIR` - Configuration directory (default: `~/.airavata`)
+
+## Configuration File
+
+The CLI stores configuration in `~/.airavata/config`:
+
+```yaml
+server_url: "http://localhost:8080"
+username: "myusername"
+token: "jwt-token-here"
+```
+
+## Exit Codes
+
+The CLI uses standard exit codes:
+
+- `0` - Success
+- `1` - General error
+- `2` - Authentication error
+- `3` - Configuration error
+- `4` - Network error
+- `5` - Resource not found
+
+## Examples
+
+### Example Experiment YAML
+
+```yaml
+name: "Hello World Experiment"
+description: "Simple hello world experiment"
+project: "proj-123"
+compute_resource: "slurm-1"

+ scheduler:
+ ports:
+ - "${PORT:-8080}:8080"
+ - "${GRPC_PORT:-50051}:50051"
+```
+
+## Configuration Validation
+
+### Required Configuration
+
+The following configuration is required for basic operation:
+
+- Database DSN or connection components
+- SpiceDB endpoint and token
+- Vault endpoint and token
+
+### Optional Configuration
+
+All other configuration has sensible defaults and is optional.
+
+### Configuration Validation
+
+The application validates configuration on startup and will fail with clear error messages if required configuration is missing or invalid.
+
+## Best Practices
+
+### Development
+
+1. Use `.env` file for local development overrides
+2. Never commit `.env` file to version control
+3. Use `config/default.yaml` for application defaults
+4. Use environment variables for deployment-specific values
+
+### Production
+
+1. Use environment variables for all sensitive configuration
+2. Use secrets management for tokens and passwords
+3. Validate all configuration before deployment
+4. Use configuration management tools (Ansible, Terraform, etc.)
+
+### Testing
+
+1. Use test-specific environment variables
+2. Override timeouts for faster test execution
+3. Use separate test databases and services
+4. Mock external services when possible
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Port conflicts**: Check that all configured ports are available
+2. **Connection timeouts**: Increase timeout values for slow networks
+3. **Authentication failures**: Verify tokens and credentials
+4. **Service discovery**: Ensure all service endpoints are reachable
+
+### Debug Configuration
+
+Enable debug logging to see configuration loading:
+
+```bash
+export LOG_LEVEL=debug
+```
+
+### Configuration Dump
+
+Use the CLI to dump current configuration:
+
+```bash
+airavata config show
+```

+# WebSocket Protocol Documentation
+
+This document describes the WebSocket protocol used by the Airavata Scheduler for real-time communication between the server and client applications.
+

+1. [Overview](#overview)
+2. [Connection Setup](#connection-setup)
+3. [Authentication](#authentication)
+4. [Message Format](#message-format)
+5. [Message Types](#message-types)

+8. [Error Handling](#error-handling)
+9. [Connection Management](#connection-management)
+10. [Examples](#examples)
+
+## Overview
+
+The Airavata Scheduler WebSocket protocol provides real-time updates for:
+
+- Experiment status changes
+- Task progress updates
+- Worker status changes
+- System health updates
+- User-specific notifications
+
+### Key Features
+
+- **Real-time Updates**: Instant notification of status changes
+- **Selective Subscriptions**: Subscribe to specific resources or events
+- **Authentication**: JWT-based authentication for secure connections
+- **Automatic Reconnection**: Built-in reconnection logic for reliability
+- **Message Acknowledgment**: Ping/pong mechanism for connection health
+
+## Connection Setup
+
+### WebSocket Endpoints
+
+The system provides several WebSocket endpoints for different types of subscriptions:
+
+```
+ws://localhost:8080/ws/experiments/{experimentId}
+ws://localhost:8080/ws/tasks/{taskId}
+ws://localhost:8080/ws/projects/{projectId}
+ws://localhost:8080/ws/user
+```
+
+### Connection URL Format
+
+```
+ws://host:port/ws/{resourceType}/{resourceId}?token={jwt_token}
+```
+
+**Parameters:**
+- `host`: Server hostname or IP address
+- `port`: Server port (default: 8080)
+- `resourceType`: Type of resource to subscribe to
+- `resourceId`: ID of the specific resource
+- `token`: JWT authentication token
+
+### Example Connections
+
+```javascript
+// Connect to experiment updates
+const experimentWs = new WebSocket('ws://localhost:8080/ws/experiments/exp-123?token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...');
+
+// Connect to user-wide updates
+const userWs = new WebSocket('ws://localhost:8080/ws/user?token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...');
+
+// Connect to project updates
+const projectWs = new WebSocket('ws://localhost:8080/ws/projects/proj-456?token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...');
+```
+
+## Authentication
+
+### JWT Token Authentication
+
+All WebSocket connections require a valid JWT token for authentication. The token can be provided in two ways:
+
+1. **Query Parameter** (Recommended):
+ ```
+ ws://localhost:8080/ws/experiments/exp-123?token=your_jwt_token
+ ```
+
+2. **Authorization Header** (Alternative):
+ ```javascript
+ const ws = new WebSocket('ws://localhost:8080/ws/experiments/exp-123', {
+ headers: {
+ 'Authorization': 'Bearer your_jwt_token'
+ }
+ });
+ ```
+
+### Token Validation
+
+The server validates the JWT token on connection and:
+
+- **Valid Token**: Connection established successfully
+- **Invalid Token**: Connection closed with error message
+- **Expired Token**: Connection closed with authentication error
+- **Missing Token**: Connection closed with authentication required error
+
+### Error Responses
+
+```json
+{
+ "type": "error",
+ "id": "error-123",
+ "timestamp": "2024-01-15T10:30:00Z",
+ "error": "Authentication required"
+}
+```
+
+## Message Format
+
+### Standard Message Structure
+
+All WebSocket messages follow a consistent JSON format:
+
+```json
+{
+ "type": "message_type",
+ "id": "unique_message_id",
+ "timestamp": "2024-01-15T10:30:00Z",
+ "data": {
+ // Message-specific data
+ },
+ "error": "error_message_if_applicable"
+}
+```
+
+### Message Fields
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `type` | string | Yes | Message type identifier |
+| `id` | string | Yes | Unique message identifier |
+| `timestamp` | string | Yes | ISO 8601 timestamp |
+| `data` | object | No | Message payload |
+| `error` | string | No | Error message (for error types) |
+
+### Message ID Format
+
+Message IDs follow a specific format for easy identification:
+
+- **Experiment Events**: `exp_{experimentId}_{timestamp}`
+- **Task Events**: `task_{taskId}_{timestamp}`
+- **Worker Events**: `worker_{workerId}_{timestamp}`
+- **System Events**: `system_{timestamp}`
+- **User Events**: `user_{userId}_{timestamp}`

+
+## Subscription Management
+
+### Subscription Request
+
+To subscribe to specific resources or events, send a subscription message:
+
+```json
+{
+ "type": "system_status",
+ "data": {
+ "action": "subscribe",
+ "resourceType": "experiment",
+ "resourceId": "exp-123"
+ }
+}
+```
+
+### Unsubscription Request
+
+To unsubscribe from resources or events:
+
+```json
+{
+ "type": "system_status",
+ "data": {
+ "action": "unsubscribe",
+ "resourceType": "experiment",
+ "resourceId": "exp-123"
+ }
+}
+```
+
+### Subscription Response
+
+The server responds to subscription requests:
+
+```json
+{
+ "type": "system_status",
+ "id": "sub-response-123",
+ "timestamp": "2024-01-15T10:30:00Z",
+ "data": {
+ "action": "subscribed",
+ "resourceType": "experiment",
+ "resourceId": "exp-123",
+ "status": "success"
+ }
+}
+```
+
+### Supported Resource Types
+
+| Resource Type | Description | Events |
+|---------------|-------------|---------|
+| `experiment` | Experiment-specific events | All experiment and task events |
+| `task` | Task-specific events | Task events only |
+| `project` | Project-wide events | All experiments in project |
+| `user` | User-specific events | All user's experiments |
+| `system` | System-wide events | System status and health |
+
+## Event Broadcasting
+
+### Broadcast Scope
+
+Events are broadcast to clients based on their subscriptions:
+
+1. **Resource-specific**: Events are sent to clients subscribed to the specific resource
+2. **User-specific**: Events are sent to clients subscribed to the user
+3. **Project-specific**: Events are sent to clients subscribed to the project
+4. **System-wide**: Events are sent to all connected clients
+
+### Event Routing
+
+```
+Experiment Event → Experiment Subscribers + Project Subscribers + User Subscribers
+Task Event → Task Subscribers + Experiment Subscribers + Project Subscribers + User Subscribers
+Worker Event → Worker Subscribers + System Subscribers
+System Event → All Subscribers
+```
+
+### Event Ordering
+
+Events are delivered in the order they occur, with timestamps to ensure proper sequencing:
+
+```json
+{
+ "type": "experiment_updated",
+ "id": "exp_exp-123_1642248600",
+ "timestamp": "2024-01-15T10:30:00Z",
+ "data": { ... }
+}
+```
+
+## Error Handling
+
+### Connection Errors
+
+#### Authentication Error
+```json
+{
+ "type": "error",
+ "id": "error-123",
+ "timestamp": "2024-01-15T10:30:00Z",
+ "error": "Authentication required"
+}
+```
+
+#### Invalid Token
+```json
+{
+ "type": "error",
+ "id": "error-124",
+ "timestamp": "2024-01-15T10:30:00Z",
+ "error": "Invalid or expired token"
+}
+```
+
+#### Rate Limit Exceeded
+```json
+{
+ "type": "error",
+ "id": "error-125",
+ "timestamp": "2024-01-15T10:30:00Z",
+ "error": "Rate limit exceeded"
+}
+```
+
+### Message Errors
+
+#### Invalid Message Format
+```json
+{
+ "type": "error",
+ "id": "error-126",
+ "timestamp": "2024-01-15T10:30:00Z",
+ "error": "Invalid message format"
+}
+```
+
+#### Unknown Message Type
+```json
+{
+ "type": "error",
+ "id": "error-127",
+ "timestamp": "2024-01-15T10:30:00Z",
+ "error": "Unknown message type"
+}
+```
+
+### Client Error Handling
+
+```javascript
+const ws = new WebSocket('ws://localhost:8080/ws/experiments/exp-123?token=your_token');
+
+ws.onerror = (error) => {
+ console.error('WebSocket error:', error);
+ // Handle connection errors
+};
+
+ws.onmessage = (event) => {
+ const message = JSON.parse(event.data);
+
+ if (message.type === 'error') {
+ console.error('Server error:', message.error);
+ // Handle server errors
+ } else {
+ // Handle normal messages
+ handleMessage(message);
+ }
+};
+```
+
+## Connection Management
+
+### Connection Lifecycle
+
+1. **Connect**: Client establishes WebSocket connection
+2. **Authenticate**: Server validates JWT token
+3. **Subscribe**: Client subscribes to desired resources
+4. **Receive**: Client receives real-time updates
+5. **Disconnect**: Connection closed by client or server
+
+### Heartbeat Mechanism
+
+The server sends periodic ping messages to maintain connection health:
+
+```json
+{
+ "type": "ping",
+ "id": "ping-123",
+ "timestamp": "2024-01-15T10:30:00Z"
+}
+```
+
+Clients should respond with pong messages:
+
+```json
+{
+ "type": "pong",
+ "id": "pong-123",
+ "timestamp": "2024-01-15T10:30:00Z"
+}
+```
+
+### Reconnection Strategy
+
+Clients should implement automatic reconnection:
+
+```javascript
+class WebSocketManager {
+ constructor() {
+ this.reconnectAttempts = 0;
+ this.maxReconnectAttempts = 5;
+ this.reconnectDelay = 1000; // 1 second
+ }
+
+ connect(url) {
+ this.ws = new WebSocket(url);
+
+ this.ws.onopen = () => {
+ console.log('Connected');
+ this.reconnectAttempts = 0;
+ };
+
+ this.ws.onclose = () => {
+ console.log('Disconnected');
+ this.handleReconnect(url);
+ };
+
+ this.ws.onerror = (error) => {
+ console.error('WebSocket error:', error);
+ };
+ }
+
+ handleReconnect(url) {
+ if (this.reconnectAttempts < this.maxReconnectAttempts) {
+ this.reconnectAttempts++;
+ const delay = this.reconnectDelay * Math.pow(2, this.reconnectAttempts - 1);
+
+ setTimeout(() => {
+ console.log(`Reconnecting... (attempt ${this.reconnectAttempts})`);
+ this.connect(url);
+ }, delay);
+ } else {
+ console.error('Max reconnection attempts reached');
+ }
+ }
+}
+```
+
+### Connection Limits
+
+- **Per User**: 10 concurrent connections
+- **Per IP**: 50 concurrent connections
+- **Global**: 1000 concurrent connections
+
+## Examples
+
+### Complete Client Implementation
+
+```javascript
+class AiravataWebSocketClient {
+ constructor(baseUrl, token) {
+ this.baseUrl = baseUrl;
+ this.token = token;
+ this.connections = new Map();
+ this.subscriptions = new Map();

+ };
+
+ ws.onmessage = (event) => {
+ const message = JSON.parse(event.data);
+ onMessage(message);
+ };
+
+ ws.onclose = () => {
+ console.log(`Disconnected from experiment ${experimentId}`);
+ this.connections.delete(experimentId);
+ };
+
+ this.connections.set(experimentId, ws);
+ return ws;
+ }
+
+ subscribe(ws, resourceType, resourceId) {
+ const message = {
+ type: 'system_status',
+ data: {
+ action: 'subscribe',
+ resourceType: resourceType,
+ resourceId: resourceId
+ }
+ };
+
+ ws.send(JSON.stringify(message));
+ }
+
+ disconnect(experimentId) {
+ const ws = this.connections.get(experimentId);
+ if (ws) {
+ ws.close();

+ }
+ }
+
+ sendPing(experimentId) {

+ type: 'ping',
+ id: `ping-${Date.now()}`,
+ timestamp: new Date().toISOString()
+ };
+
+ ws.send(JSON.stringify(message));
+ }
+ }
+}
+
+// Usage
+const client = new AiravataWebSocketClient('ws://localhost:8080', 'your_jwt_token');
+
+client.connectToExperiment('exp-123', (message) => {
+ switch (message.type) {

+ case 'task_updated':
+ console.log('Task updated:', message.data);
+ break;
+ case 'pong':
+ console.log('Pong received');
+ break;
+ }
+});
+```
+

+# Worker System Documentation
+
+## Overview
+
+The Airavata Scheduler uses a distributed worker architecture where standalone worker binaries communicate with the scheduler via gRPC. This design enables scalable, fault-tolerant task execution across multiple compute resources.
+
+## Architecture
+

+```
+
+### Key Benefits
+
+- **Scalability**: Workers can be deployed across multiple compute resources
+- **Isolation**: Worker failures don't affect the scheduler
+- **Flexibility**: Workers can be deployed on different platforms (SLURM, Kubernetes, Bare Metal)
+- **Efficiency**: Direct binary deployment without container overhead
+- **Fault Tolerance**: Automatic worker recovery and task reassignment
+
+## Worker Lifecycle
+
+### 1. Deployment
+
+Workers are deployed to compute resources using runtime-specific scripts:
+
+```bash
+# SLURM deployment
+sbatch worker_spawn_script.sh
+
+# Kubernetes deployment
+kubectl apply -f worker_job.yaml
+
+# Bare metal deployment
+ssh compute-node 'bash -s' < worker_script.sh
+```
+
+### 2. Registration
+
+Upon startup, workers connect to the scheduler gRPC server:
+
+```go
+// Worker registration
+conn, err := grpc.Dial("scheduler:50051", grpc.WithInsecure())
+client := workerpb.NewWorkerServiceClient(conn)
+
+// Register with scheduler
+resp, err := client.RegisterWorker(ctx, &workerpb.RegisterWorkerRequest{
+ WorkerId: workerID,
+ Capabilities: capabilities,
+ Status: workerpb.WorkerStatus_AVAILABLE,
+})
+```
+
+### 3. Task Polling
+
+Workers continuously poll for available tasks:
+
+```go
+// Poll for tasks
+for {
+ resp, err := client.PollForTask(ctx, &workerpb.PollForTaskRequest{
+ WorkerId: workerID,
+ Capabilities: capabilities,
+ })
+
+ if resp.Task != nil {
+ // Execute task
+ executeTask(resp.Task)
+ }
+
+ time.Sleep(pollInterval)
+}
+```
+
+### 4. Task Execution
+
+Workers execute assigned tasks with proper isolation:
+
+```go
+func executeTask(task *workerpb.Task) error {
+ // Update status to running
+ client.UpdateTaskStatus(ctx, &workerpb.UpdateTaskStatusRequest{
+ TaskId: task.Id,
+ Status: workerpb.TaskStatus_RUNNING,
+ })
+
+ // Stage input files
+ for _, input := range task.InputFiles {
+ stageFile(input)
+ }
+
+ // Execute command
+ cmd := exec.Command("bash", "-c", task.Command)
+ output, err := cmd.CombinedOutput()
+
+ // Update status
+ status := workerpb.TaskStatus_COMPLETED
+ if err != nil {
+ status = workerpb.TaskStatus_FAILED
+ }
+
+ client.UpdateTaskStatus(ctx, &workerpb.UpdateTaskStatusRequest{
+ TaskId: task.Id,
+ Status: status,
+ Output: string(output),
+ })
+
+ return err
+}
+```
+
+### 5. Status Reporting
+
+Workers report progress and completion status:
+
+```go
+// Send heartbeat
+client.SendHeartbeat(ctx, &workerpb.HeartbeatRequest{
+ WorkerId: workerID,
+ Status: workerpb.WorkerStatus_AVAILABLE,
+ Metrics: &workerpb.WorkerMetrics{
+ CpuUsage: cpuUsage,
+ MemoryUsage: memoryUsage,
+ ActiveTasks: activeTaskCount,
+ },
+})
+```
+
+### 6. Cleanup
+
+Workers clean up resources and report final status:
+
+```go
+// Cleanup on shutdown
+client.UpdateWorkerStatus(ctx, &workerpb.UpdateWorkerStatusRequest{
+ WorkerId: workerID,
+ Status: workerpb.WorkerStatus_TERMINATED,
+})
+
+conn.Close()
+```
+
+## Script Generation
+
+The system generates runtime-specific scripts for deploying workers to different compute resources.
+
+### SLURM Scripts
+
+```bash
+#!/bin/bash
+#SBATCH --job-name=worker_${WORKER_ID}
+#SBATCH --time=${WALLTIME}

+# Set up environment
+export WORKER_ID="${WORKER_ID}"
+export EXPERIMENT_ID="${EXPERIMENT_ID}"
+export COMPUTE_RESOURCE_ID="${COMPUTE_RESOURCE_ID}"

+export WORKER_BINARY_URL="${WORKER_BINARY_URL}"
+export SERVER_ADDRESS="${SERVER_ADDRESS}"
+export SERVER_PORT="${SERVER_PORT}"
+
+# Create working directory
+mkdir -p "${WORKING_DIR}"
+cd "${WORKING_DIR}"
+
+# Download worker binary
+echo "Downloading worker binary from ${WORKER_BINARY_URL}"
+curl -L "${WORKER_BINARY_URL}" -o worker

+
+## Task Execution
+
+### Task Assignment
+
+Tasks are assigned to workers based on:
+
+- **Capabilities**: CPU, memory, GPU requirements
+- **Availability**: Worker status and current load
+- **Affinity**: Data locality and resource preferences
+- **Priority**: Task priority and deadline constraints
+
+### Data Staging
+
+Input files are staged to workers before task execution:
+
+```go
+func stageInputFiles(task *workerpb.Task) error {
+ for _, input := range task.InputFiles {
+ // Download from storage
+ err := downloadFile(input.Source, input.Destination)
+ if err != nil {
+ return fmt.Errorf("failed to stage file %s: %w", input.Source, err)
+ }
+ }
+ return nil
+}
+```
+
+### Command Execution
+
+Tasks are executed in isolated environments:
+
+```go
+func executeCommand(command string, workingDir string) (*exec.Cmd, error) {
+ cmd := exec.Command("bash", "-c", command)
+ cmd.Dir = workingDir
+
+ // Set up environment
+ cmd.Env = append(os.Environ(),
+ "WORKING_DIR="+workingDir,
+ "TASK_ID="+taskID,
+ )
+
+ // Set resource limits
+ cmd.SysProcAttr = &syscall.SysProcAttr{
+ Setpgid: true,
+ }
+
+ return cmd, nil
+}
+```
+
+### Result Collection
+
+Output files are collected after task completion:
+
+```go
+func collectOutputFiles(task *workerpb.Task) error {
+ for _, output := range task.OutputFiles {
+ // Upload to storage
+ err := uploadFile(output.Source, output.Destination)
+ if err != nil {
+ return fmt.Errorf("failed to collect file %s: %w", output.Source, err)
+ }
+ }
+ return nil
+}
+```
+
+## Monitoring and Health Checks
+
+### Heartbeat System
+
+Workers send periodic heartbeats to the scheduler:
+
+```go
+func sendHeartbeat(client workerpb.WorkerServiceClient, workerID string) {
+ ticker := time.NewTicker(heartbeatInterval)
+ defer ticker.Stop()
+
+ for range ticker.C {
+ _, err := client.SendHeartbeat(ctx, &workerpb.HeartbeatRequest{
+ WorkerId: workerID,
+ Status: workerpb.WorkerStatus_AVAILABLE,
+ Metrics: &workerpb.WorkerMetrics{
+ CpuUsage: getCPUUsage(),
+ MemoryUsage: getMemoryUsage(),
+ ActiveTasks: getActiveTaskCount(),
+ Timestamp: time.Now().Unix(),
+ },
+ })
+
+ if err != nil {
+ log.Printf("Failed to send heartbeat: %v", err)
+ }
+ }
+}
+```
+
+### Health Monitoring
+
+The scheduler monitors worker health and handles failures:
+
+```go
+func monitorWorkerHealth(workerID string) {
+ ticker := time.NewTicker(healthCheckInterval)
+ defer ticker.Stop()
+
+ for range ticker.C {
+ if !isWorkerHealthy(workerID) {
+ // Mark worker as unhealthy
+ markWorkerUnhealthy(workerID)
+
+ // Reassign tasks to other workers
+ reassignWorkerTasks(workerID)
+ }
+ }
+}
+```
+
+## Error Handling
+
+### Worker Failures
+
+When workers fail, the scheduler:
+
+1. **Detects Failure**: Via missed heartbeats or connection errors
+2. **Marks Unhealthy**: Updates worker status in database
+3. **Reassigns Tasks**: Moves pending tasks to other workers
+4. **Cleans Up**: Removes worker from active pool
+
+### Task Failures
+
+Task failures are handled gracefully:
+
+```go
+func handleTaskFailure(taskID string, err error) {
+ // Update task status
+ updateTaskStatus(taskID, TaskStatusFailed, err.Error())
+
+ // Log failure
+ log.Printf("Task %s failed: %v", taskID, err)
+
+ // Retry if appropriate
+ if shouldRetry(taskID) {
+ scheduleTaskRetry(taskID)
+ }
+}
+```
+
+### Network Failures
+
+Network connectivity issues are handled with:
+
+- **Retry Logic**: Exponential backoff for failed requests
+- **Circuit Breaker**: Prevent cascading failures
+- **Graceful Degradation**: Continue with available workers
+
+## Security
+
+### Authentication
+
+Workers authenticate with the scheduler using:
+
+- **TLS Certificates**: Mutual TLS for gRPC connections
+- **API Keys**: Worker-specific authentication tokens
+- **Network Policies**: Firewall rules and network segmentation
+
+### Isolation
+
+Task execution is isolated through:
+
+- **Process Isolation**: Separate processes for each task
+- **Resource Limits**: CPU, memory, and disk quotas
+- **Network Isolation**: Restricted network access
+- **File System Isolation**: Sandboxed working directories
+
+## Performance Optimization
+
+### Connection Pooling
+
+gRPC connections are pooled for efficiency:
+
+```go
+type ConnectionPool struct {
+ connections map[string]*grpc.ClientConn
+ mutex sync.RWMutex
+}
+
+func (p *ConnectionPool) GetConnection(address string) (*grpc.ClientConn, error) {
+ p.mutex.RLock()
+ conn, exists := p.connections[address]
+ p.mutex.RUnlock()
+
+ if exists {
+ return conn, nil
+ }
+
+ // Create new connection
+ conn, err := grpc.Dial(address, grpc.WithInsecure())
+ if err != nil {
+ return nil, err
+ }
+
+ p.mutex.Lock()
+ p.connections[address] = conn
+ p.mutex.Unlock()
+
+ return conn, nil
+}
+```
+
+### Batch Operations
+
+Multiple operations are batched for efficiency:
+
+```go
+func batchUpdateTaskStatus(updates []TaskStatusUpdate) error {
+ req := &workerpb.BatchUpdateTaskStatusRequest{
+ Updates: make([]*workerpb.TaskStatusUpdate, len(updates)),
+ }
+
+ for i, update := range updates {
+ req.Updates[i] = &workerpb.TaskStatusUpdate{
+ TaskId: update.TaskID,
+ Status: update.Status,
+ Output: update.Output,
+ }
+ }
+
+ _, err := client.BatchUpdateTaskStatus(ctx, req)
+ return err
+}
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### Worker Not Connecting
+
+**Symptoms**: Worker fails to connect to scheduler
+**Causes**: Network issues, incorrect server address, firewall blocking
+**Solutions**:
+- Verify network connectivity: `telnet scheduler-host 50051`
+- Check firewall rules
+- Verify server address and port configuration
+
+#### Task Execution Failures
+
+**Symptoms**: Tasks fail to execute or complete
+**Causes**: Resource limits, permission issues, command errors
+**Solutions**:
+- Check worker logs for error messages
+- Verify resource limits and permissions
+- Test commands manually on worker node
+
+#### High Memory Usage
+
+**Symptoms**: Workers consuming excessive memory
+**Causes**: Memory leaks, large input files, inefficient processing
+**Solutions**:
+- Monitor memory usage with `htop` or `ps`
+- Implement memory limits for tasks
+- Optimize data processing algorithms
+
+### Debugging
+
+#### Enable Debug Logging
+
+```bash
+# Set debug log level
+export LOG_LEVEL=debug
+
+# Start worker with verbose output
+./worker --log-level=debug --server-address=localhost:50051
+```
+
+#### Monitor Worker Status
+
+```bash
+# Check worker processes
+ps aux | grep worker
+
+# Monitor network connections
+netstat -an | grep 50051
+
+# Check worker logs
+tail -f /var/log/worker.log
+```
+
+#### Test gRPC Connectivity
+
+```bash
+# Test gRPC server connectivity
+grpcurl -plaintext localhost:50051 list
+
+# Test specific service
+grpcurl -plaintext localhost:50051 worker.WorkerService/ListWorkers
+```
+
+## Best Practices
+
+### Worker Deployment
+
+1. **Use Resource Limits**: Set appropriate CPU and memory limits
+2. **Monitor Health**: Implement comprehensive health checks
+3. **Handle Failures**: Implement proper error handling and recovery
+4. **Secure Communication**: Use TLS for gRPC connections
+5. **Log Everything**: Comprehensive logging for debugging
+
+### Task Execution
+
+1. **Isolate Tasks**: Run each task in separate process
+2. **Limit Resources**: Set appropriate resource quotas
+3. **Clean Up**: Always clean up temporary files and processes
+4. **Validate Inputs**: Verify input files and parameters
+5. **Handle Timeouts**: Implement proper timeout handling
+
+### Performance
+
+1. **Connection Pooling**: Reuse gRPC connections
+2. **Batch Operations**: Group multiple operations together
+3. **Async Processing**: Use asynchronous operations where possible
+4. **Resource Monitoring**: Monitor CPU, memory, and disk usage
+5. **Load Balancing**: Distribute tasks evenly across workers

+# Testing Guide
+
+## Overview
+
+This guide provides comprehensive instructions for running and developing tests for the Airavata Scheduler. The system uses a multi-layered testing approach with unit tests, integration tests, and end-to-end tests following hexagonal architecture principles.
+
+## Prerequisites
+
+- Go 1.21+
+- Docker and Docker Compose
+- PostgreSQL 15+ (for integration tests)
+- Make (optional, for convenience targets)
+
+## Quick Start
+
+### Run All Tests
+```bash
+make test
+# or
+go test ./... -v
+```
+
+### Run Unit Tests Only
+```bash
+make test-unit
+# or
+go test ./tests/unit/... -v
+```
+
+### Run Integration Tests
+
+#### Cold Start Integration Tests (Recommended)
+```bash
+# Complete cold start setup and run integration tests
+./scripts/setup-cold-start.sh
+./scripts/test/run-integration-tests.sh
+
+# This automatically:
+# 1. Validates prerequisites
+# 2. Generates deterministic SLURM munge key
+# 3. Starts all services with test profile
+# 4. Builds binaries
+# 5. Runs integration tests
+# 6. Cleans up
+```
+
+#### Complete Functionality Validation
+```bash
+# Run complete validation including cold-start, unit tests, and integration tests
+./scripts/validate-full-functionality.sh
+
+# This performs:
+# 1. Cold-start setup validation
+# 2. Unit test execution (30m timeout)
+# 3. Integration test execution (60m timeout)
+# 4. Summary report generation
+# 5. Test coverage analysis
+```
+
+#### Cold Start Testing with CSV Reports
+```bash
+# Full cold start test with detailed CSV report generation
+make cold-start-test-csv
+
+# Or run directly with options
+./scripts/test/run-cold-start-with-report.sh [OPTIONS]
+
+# Options:
+# --skip-cleanup Skip Docker cleanup (useful for debugging)
+# --skip-cold-start Skip cold start setup (assume environment is ready)
+# --unit-only Run only unit tests
+# --integration-only Run only integration tests
+# --no-csv Skip CSV report generation
+```
+
+**This comprehensive test will:**
+1. **Destroy all containers and volumes** for a true cold start
+2. **Recreate environment from scratch** using `scripts/setup-cold-start.sh`
+3. **Run all test suites** (unit + integration) with JSON output
+4. **Generate detailed CSV report** with test results in `logs/cold-start-test-results-[timestamp].csv`
+
+**CSV Report Features:**
+- Test categorization (Unit vs Integration)
+- Individual test status (PASS/FAIL/SKIP/PASS_WITH_WARNING)
+- Test duration tracking
+- Warning/error message capture
+- Summary statistics with success rates
+- Proper CSV escaping for complex output
+
+**Generated Files:**
+- `logs/cold-start-test-results-[timestamp].csv` - Detailed test results
+- `logs/unit-tests-[timestamp].json` - Unit test JSON output
+- `logs/integration-tests-[timestamp].json` - Integration test JSON output
+- `logs/cold-start-setup-[timestamp].log` - Cold start setup log
+
+**CSV Format:**
+```
+Category,Test Name,Status,Duration (s),Warnings/Notes
+Unit,TestExample,PASS,0.123,
+Integration,TestE2E,FAIL,45.67,Timeout waiting for service
+Integration,TestStorage,PASS_WITH_WARNING,12.34,Service took longer than expected
+```
+
+#### Manual Integration Test Setup
+```bash
+# Start Docker services first (test profile)
+docker compose --profile test up -d
+
+# Build worker binary (required for integration tests)
+make build-worker
+
+# Run integration tests
+make test-integration
+# or
+go test ./tests/integration/... -v
+
+# Clean up
+docker compose --profile test down
+```
+
+### Enhanced Integration Test Execution
+The integration tests now include comprehensive end-to-end workflows:
+
+```bash
+# Run specific enhanced integration tests
+go test ./tests/integration/worker_system_e2e_test.go -v
+go test ./tests/integration/connectivity_e2e_test.go -v
+go test ./tests/integration/signed_url_staging_e2e_test.go -v
+go test ./tests/integration/robustness_e2e_test.go -v
+
+# Run with extended timeout for E2E tests
+go test ./tests/integration/... -v -timeout=30m
+```
+
+**Key Enhanced Test Categories**:
+- **Worker System E2E**: Real gRPC communication, worker spawning, task execution
+- **Connectivity Tests**: Docker service health verification, network connectivity
+- **Signed URL Staging**: Complete data staging workflow with MinIO
+
+### ✅ Enhanced Integration Tests
+
+Integration tests have been significantly enhanced with:
+- **Real gRPC Communication**: Tests now use actual gRPC server/client communication instead of mock validation
+- **Complete E2E Workflows**: Full end-to-end scenarios from worker spawning to task completion
+- **Docker Service Health Verification**: Tests verify actual Docker service connectivity and health
+- **Worker Binary Integration**: Tests spawn and interact with real worker processes
+- **Data Staging Validation**: Complete signed URL workflow testing with MinIO integration
+
+### ⚠️ Integration Test Execution Requirements
+
+Integration tests now require:
+- **Docker Services**: PostgreSQL, MinIO, SLURM clusters, SFTP, NFS, SSH servers
+- **Worker Binary**: Must be built before running integration tests
+- **Network Connectivity**: Services must be accessible and healthy
+- **Service Startup Time**: Allow 2-3 minutes for all services to become healthy
+
+### Automated Execution
+
+Use the provided script for automated test execution:
+
+```bash
+./scripts/test/run-integration-tests.sh
+```
+
+This script will:
+1. Start all Docker services
+2. Wait for services to become healthy
+3. Build the worker binary
+4. Run all integration tests
+5. Clean up Docker services
+
+### Manual Execution
+
+If you need to run tests manually:
+
+1. Start Docker services:
+```bash
+docker compose --profile test up -d
+```
+
+2. Wait for services (2-3 minutes):
+```bash
+sleep 180
+```
+
+3. Build worker binary:
+```bash
+make build-worker
+```
+
+4. Run tests:
+```bash
+go test -v -timeout 30m ./tests/integration/...
+```
+
+5. Cleanup:
+```bash
+docker compose --profile test down -v
+```
+- **Robustness Tests**: Worker failure scenarios, timeout handling, retry mechanisms
+
+### Automated Test Execution Script
+Use the provided script for automated integration test execution:
+
+```bash
+# Run the automated integration test script
+./scripts/test/run-integration-tests.sh
+
+# This script will:
+# 1. Start Docker services
+# 2. Wait for services to be healthy
+# 3. Build worker binary
+# 4. Run integration tests
+# 5. Clean up services
+```
+
+## Current Test Status
+
+### ✅ Compilation Status
+- **Unit Tests**: All 27 test files compile and run successfully
+- **Integration Tests**: All 16 test files compile successfully
+- **Proto/gRPC Tests**: New test files added for comprehensive coverage
+
+### ✅ Enhanced Integration Tests
+Integration tests have been significantly enhanced with:
+- **Real gRPC Communication**: Tests now use actual gRPC server/client communication instead of mock validation
+- **Complete E2E Workflows**: Full end-to-end scenarios from worker spawning to task completion
+- **Docker Service Health Verification**: Tests verify actual Docker service connectivity and health
+- **Worker Binary Integration**: Tests spawn and interact with real worker processes
+- **Data Staging Validation**: Complete signed URL workflow testing with MinIO integration
+- **Real Worker Spawning**: Tests spawn actual worker processes on SLURM, Kubernetes, and Bare Metal
+- **Complete Data Staging Workflow**: Input staging → execution → output staging with proper state transitions
+- **Output Collection API**: Tests for listing and downloading experiment outputs organized by experiment ID
+- **Cross-Storage Data Movement**: Tests data staging across different storage types (S3, SFTP, NFS)
+
+### ⚠️ Integration Test Execution Requirements
+Integration tests now require:
+- **Docker Services**: PostgreSQL, MinIO, SLURM clusters, SFTP, NFS, SSH servers
+- **Worker Binary**: Must be built before running integration tests
+- **Network Connectivity**: Services must be accessible and healthy
+- **Service Startup Time**: Allow 2-3 minutes for all services to become healthy
+
+**Note**: Test compilation errors have been resolved. Current failures are infrastructure-related, not code issues.
+
+## Infrastructure Requirements
+
+### Required Services
+Integration tests require the following Docker services (defined in `docker-compose.yml` with test profile):
+
+#### Core Services
+- **PostgreSQL**: Database for test data storage
+ - Port: 5432
+ - Database: `airavata_test`
+ - User: `postgres` / Password: `password`
+
+#### Storage Services
+- **MinIO**: S3-compatible object storage
+ - Port: 9000 (API), 9001 (Console)

+ - Storage backends (S3, SFTP, NFS)
+ - Worker system and gRPC communication
+ - Data staging and transfer
+ - Authentication and permissions
+ - Multi-runtime workflows
+
+## Test Architecture
+
+### Hexagonal Testing Strategy
+
+Tests are organized to match the hexagonal architecture:
+
+- **Domain Tests**: Test pure business logic without external dependencies
+- **Service Tests**: Test service implementations with mocked ports
+- **Port Tests**: Test infrastructure interfaces with real implementations
+- **Adapter Tests**: Test external system integrations
+

+```
+
+## Test Categories
+
+### Unit Tests (Foundation)
+
+**Purpose**: Test individual components in isolation
+**Speed**: Fast (< 100ms per test)
+**Dependencies**: None (use mocks)
+**Coverage**: 80%+ of business logic
+
+```bash
+# Run specific unit test package
+go test ./tests/unit/core -v
+
+# Run specific test
+go test ./tests/unit/core -v -run TestResourceValidation
+
+# With coverage
+go test ./tests/unit/core -v -cover
+```
+
+**Key Unit Test Areas**:
+- Type validation and serialization
+- Core service logic (cost calculation, scheduling algorithms)
+- State machine transitions
+- Authentication and authorization logic
+- Data validation and transformation
+
+#### Domain Tests
+Test pure business logic in the `core/domain/` package:
+
+```go
+func TestTaskStatus_Transitions(t *testing.T) {
+ // Test domain value objects and business rules
+ assert.True(t, domain.TaskStatusQueued.CanTransitionTo(domain.TaskStatusAssigned))
+ assert.False(t, domain.TaskStatusCompleted.CanTransitionTo(domain.TaskStatusQueued))
+}
+```
+
+#### Service Tests
+Test service implementations with mocked ports:
+
+```go
+func TestExperimentService_CreateExperiment(t *testing.T) {
+ // Arrange
+ mockRepo := &MockRepository{}
+ mockCache := &MockCache{}
+ service := orchestrator.NewFactory(mockRepo, mockCache)
+
+ // Act
+ result, err := service.CreateExperiment(ctx, req)
+
+ // Assert
+ assert.NoError(t, err)
+ assert.NotNil(t, result)
+}
+```
+
+### Integration Tests (Middle Layer)
+
+**Purpose**: Test component interactions with real services
+**Speed**: Medium (1-10s per test)
+**Dependencies**: Docker services (PostgreSQL, MinIO, SFTP)
+**Coverage**: Critical workflows and data flows
+
+```bash
+# Run all integration tests
+go test ./tests/integration/... -v
+
+# Run specific integration test
+go test ./tests/integration/api -v -run TestCreateExperiment
+
+# Run with race detection
+go test ./tests/integration/... -v -race
+```
+
+**Key Integration Test Areas**:
+- API endpoints with real database
+- Storage adapter operations (S3, SFTP, NFS)
+- Worker lifecycle and task execution
+- Scheduler daemon operations
+- Multi-user scenarios and isolation
+- Credential management and vault operations
+
+#### PostgreSQL Schema Isolation
+
+Each integration test gets its own PostgreSQL schema to ensure complete isolation:
+
+```go
+func TestIntegrationFeature(t *testing.T) {
+ testDB := testutil.SetupFreshPostgresTestDB(t)
+ defer testDB.Cleanup()
+
+ // ... test code ...
+}
+```
+
+The `SetupFreshPostgresTestDB` function:
+- Creates a unique schema per test (e.g., `test_MyTest_1760484706714868000`)
+- Sets `search_path` to that schema
+- Runs migrations within that schema
+- Cleanup drops the entire schema
+
+### End-to-End Tests (Top Layer)
+
+**Purpose**: Test complete user workflows
+**Speed**: Slow (10s+ per test)
+**Dependencies**: Full system stack
+**Coverage**: Key user journeys
+
+```bash
+# Run E2E tests
+go test ./tests/integration/e2e_workflow_test.go -v
+
+# Run specific E2E scenario
+go test ./tests/integration/e2e_workflow_test.go -v -run TestCompleteExperimentLifecycle
+```
+
+**Key E2E Test Areas**:
+- Complete experiment lifecycle (create → submit → execute → results)
+- Multi-resource workflows (SLURM + Kubernetes + S3)
+- Data staging across different storage backends
+- Failure recovery and error handling
+- Performance under realistic load
+
+### Enhanced Test Types
+
+#### Real Worker Spawning Tests
+Tests that spawn actual worker processes on different compute resources:
+
+```bash
+# Run worker spawning tests
+go test ./tests/integration/worker_system_e2e_test.go -v
+
+# Test specific compute resource
+go test ./tests/integration/slurm_e2e_test.go -v -run TestSlurmCluster1_HelloWorld
+```
+
+**Features**:
+- Real worker process execution on SLURM, Kubernetes, and Bare Metal
+- Worker registration and heartbeat verification
+- Task assignment and execution validation
+- Worker metrics and status monitoring
+
+#### Data Staging Workflow Tests
+Tests the complete data staging workflow from input to output:
+
+```bash
+# Run data staging tests
+go test ./tests/integration/data_staging_e2e_test.go -v
+
+# Test specific staging scenario
+go test ./tests/integration/data_staging_e2e_test.go -v -run TestDataStaging_InputStaging
+```
+
+**Features**:
+- Input staging (central storage → compute node)
+- Task execution with staged inputs
+- Output staging (compute node → central storage)
+- Cross-storage data movement (S3 → SLURM → NFS)
+- Data integrity verification with checksums

+## Test Data Management
+
+### Test Isolation
+
+Each test should be isolated and clean up after itself:
+
+```go
+func TestExample(t *testing.T) {
+ // Setup
+ testDB := testutil.SetupTestDB(t)
+ defer testDB.Cleanup()
+
+ // Test logic
+ // ...
+}
+```
+
+### Entity IDs
+
+**NEVER** use hardcoded IDs like `"test-user-1"`, `"test-worker-1"`, etc.
+
+**ALWAYS** use dynamic IDs:
+
+```go
+// BAD - hardcoded ID causes UNIQUE constraint failures
+worker := &types.Worker{
+ ID: "test-worker-1",
+ // ...
+}
+
+// GOOD - unique ID per test run
+worker := &types.Worker{
+ ID: uniqueID("test-worker"), // or fmt.Sprintf("test-worker-%d", time.Now().UnixNano())
+ // ...
+}
+```
+
+Use the `uniqueID()` helper function from `test_helpers.go`:
+
+```go
+workerID := uniqueID("worker")
+userID := uniqueID("user")
+experimentID := uniqueID("experiment")
+```
+
+### Test Data Generation
+
+Use the test utilities for consistent test data:
+
+```go
+// Generate unique test data
+userID := testutil.GenerateTestUserID()
+resourceID := testutil.GenerateTestResourceID()
+
+// Create test fixtures
+user := testutil.CreateTestUser(t, testDB, userID)
+resource := testutil.CreateTestComputeResource(t, testDB, resourceID)
+```
+
+## Common Test Patterns
+
+### Database Tests
+
+```go
+func TestDatabaseOperation(t *testing.T) {
+ testDB := setupTestDB(t)
+ defer cleanupTestDB(t, testDB)
+
+ // Test database operations
+ repo := core.NewUserRepository(testDB.DB)
+ user, err := repo.Create(ctx, testUser)
+ require.NoError(t, err)
+ assert.NotEmpty(t, user.ID)
+}
+```
+
+### API Tests
+
+```go
+func TestAPIEndpoint(t *testing.T) {
+ testDB := testutil.SetupTestDB(t)
+ defer testDB.Cleanup()
+
+ // Setup API handlers
+ handlers := api.NewAPIHandlers(testDB.DB)
+ router := api.SetupRouter(handlers)
+
+ // Make HTTP request
+ req := httptest.NewRequest("POST", "/api/v1/experiments", body)
+ w := httptest.NewRecorder()
+ router.ServeHTTP(w, req)
+
+ assert.Equal(t, http.StatusCreated, w.Code)
+}
+```
+
+### Storage Adapter Tests
+
+```go
+func TestStorageAdapter(t *testing.T) {
+ if !testutil.DockerServicesAvailable() {
+ t.Skip("Docker services not available")
+ }
+
+ // Setup storage resource and credentials
+ resource := testutil.CreateTestStorageResource(t, testDB)
+ credential := testutil.CreateTestCredential(t, testDB, resource.ID)
+
+ // Test adapter operations
+ adapter := storage.NewStorageAdapter(resource, vault)
+ err := adapter.Upload("/test/file.txt", data, userID)
+ require.NoError(t, err)
+}
+```
+
+### Adapter Tests
+Test external system integrations:
+
+```go
+func TestSlurmAdapter_SpawnWorker(t *testing.T) {
+ if !*integration {
+ t.Skip("Integration tests disabled")
+ }
+
+ adapter := slurm.NewAdapter(slurmConfig)
+ result, err := adapter.SpawnWorker(ctx, 1*time.Hour)
+ assert.NoError(t, err)
+}
+```
+
+## Performance Testing
+
+### Load Testing
+
+```bash
+# Run performance tests
+go test ./tests/performance/... -v
+
+# Run with specific load
+go test ./tests/performance/... -v -run TestHighThroughput
+```
+
+### Benchmarking
+
+```bash
+# Run benchmarks
+go test ./tests/unit/core -bench=.
+
+# Run specific benchmark
+go test ./tests/unit/core -bench=BenchmarkCostCalculation
+```
+
+## Test Utilities
+
+### Helper Functions
+
+Located in `tests/testutil/`:
+
+- `setupTestDB(t *testing.T) *core.Database` - Creates an isolated SQLite in-memory database
+- `cleanupTestDB(t *testing.T, db *core.Database)` - Closes the database connection
+- `uniqueID(prefix string) string` - Generates a unique ID with the given prefix
+- `SetupFreshPostgresTestDB(t *testing.T)` - Creates isolated PostgreSQL schema
+- `DockerServicesAvailable()` - Checks if Docker services are running
+
+### Docker Compose Helper (`testutil/docker_compose_helper.go`)
+- Service startup/shutdown
+- Health check monitoring
+- Connection information
+- Test environment setup
+
+### Service Checks (`testutil/service_checks.go`)
+- Docker availability
+- Kubernetes cluster access
+- Service port availability
+- Graceful test skipping
+
+### Adapter Fixtures (`testutil/adapter_fixtures.go`)
+- Test file generation
+- Script creation
+- Resource configuration
+- Data verification
+
+## Troubleshooting
+
+### Common Issues
+
+**1. Docker Services Not Available**
+```bash
+# Check if services are running
+docker compose --profile test ps
+
+# Restart services
+docker compose --profile test down
+docker compose --profile test up -d
+```
+
+**2. Database Connection Issues**
+```bash
+# Check PostgreSQL logs
+docker compose --profile test logs postgres
+
+# Verify database is accessible
+docker exec -it airavata-scheduler-postgres-1 psql -U airavata -d airavata_scheduler
+```
+
+**3. Test Timeouts**
+```bash
+# Increase timeout for slow tests
+go test ./tests/integration/... -v -timeout=5m
+```
+
+**4. Race Conditions**
+```bash
+# Run with race detection
+go test ./tests/integration/... -v -race
+```
+
+**5. UNIQUE constraint failed**
+
+**Cause**: Tests are sharing database state or using hardcoded IDs
+
+**Solution**: Ensure each test creates its own database with `setupTestDB(t)` and use `uniqueID()` for entity IDs
+
+**6. Incorrect counts (finding more items than created)**
+
+**Cause**: Test is seeing data from previous tests
+
+**Solution**: Ensure test is creating its own isolated database, not reusing a shared one
+
+**7. Tests pass individually but fail together**
+
+**Cause**: Tests are affecting each other's state
+
+**Solution**: Verify each test function and subtest creates its own database with `setupTestDB(t)`
+
+**8. Test hangs indefinitely**
+
+**Cause**: Waiting for unavailable external service without timeout
+
+**Solution**: Use `testutil.SetupFreshPostgresTestDB(t)` which skips if PostgreSQL unavailable, or add explicit timeouts
+
+### Debug Mode
+
+Enable debug logging for tests:
+
+```bash
+# Set debug environment variable
+export TEST_DEBUG=1
+go test ./tests/integration/... -v
+```
+
+### Test Coverage
+
+Generate and view test coverage:
+
+```bash
+# Generate coverage report
+go test ./... -coverprofile=coverage.out
+
+# View coverage in browser
+go tool cover -html=coverage.out
+
+# Coverage by package
+go test ./... -coverprofile=coverage.out
+go tool cover -func=coverage.out
+```
+
+## Continuous Integration
+
+### GitHub Actions
+
+The project includes GitHub Actions workflows for automated testing:
+
+- **Unit Tests**: Run on every push
+- **Integration Tests**: Run on pull requests
+- **E2E Tests**: Run on main branch
+
+### Local CI Simulation
+
+```bash
+# Run full CI pipeline locally
+make ci
+
+# This runs:
+# - go fmt
+# - go vet
+# - go test (unit)
+# - go test (integration)
+# - go test (e2e)
+```
+
+## Best Practices
+
+### Writing Tests
+
+1. **Use descriptive test names**: `TestComputeResourceValidation_WithInvalidCredentials`
+2. **Test one thing per test**: Each test should verify a single behavior
+3. **Use table-driven tests** for multiple scenarios
+4. **Clean up resources**: Always use `defer` for cleanup
+5. **Use appropriate assertions**: `require` for setup, `assert` for verification
+
+### Test Organization
+
+1. **Group related tests**: Use subtests with `t.Run()`
+2. **Use test utilities**: Don't duplicate setup code
+3. **Mock external dependencies**: Keep unit tests fast and isolated
+4. **Test error conditions**: Verify proper error handling
+
+### Performance Considerations
+
+1. **Parallel tests**: Use `t.Parallel()` for independent tests
+2. **Skip slow tests**: Use `t.Skip()` when services unavailable
+3. **Reuse resources**: Set up expensive resources once per test suite
+4. **Clean up promptly**: Don't leave resources running
+
+## Environment Variables
+
+### Test Configuration
+
+```bash
+# Database
+TEST_DATABASE_URL="postgres://airavata:test123@localhost:5432/airavata_scheduler_test"
+
+# Services
+TEST_MINIO_ENDPOINT="localhost:9000"
+TEST_SFTP_HOST="localhost"
+TEST_SFTP_PORT="2222"
+
+# Debug
+TEST_DEBUG=1
+TEST_VERBOSE=1
+```
+
+### Production vs Test
+
+Tests use separate databases and services to avoid conflicts:
+
+- **Test Database**: `airavata_scheduler_test`
+- **Test MinIO**: Different bucket names
+- **Test SFTP**: Isolated test directory
+
+## Quality Gates
+
+### Coverage Requirements
+- **Unit Tests**: 80%+ code coverage
+- **Integration Tests**: 100% of critical workflows
+- **E2E Tests**: All major user journeys
+
+### Performance Benchmarks
+- **Unit Tests**: < 100ms per test
+- **Integration Tests**: < 10s per test
+- **E2E Tests**: < 60s per test
+- **Full Test Suite**: < 10 minutes
+
+### Reliability Standards
+- **Flaky Tests**: Zero tolerance
+- **Race Conditions**: All tests pass with `-race` flag
+- **Resource Leaks**: No memory or connection leaks
+- **Cleanup**: All resources properly cleaned up
+
+## When to Write Each Test Type
+
+### Write Unit Tests When:
+- Testing pure business logic
+- Validating data transformations
+- Testing error handling
+- Verifying algorithm correctness
+
+### Write Integration Tests When:
+- Testing database operations
+- Validating external service interactions
+- Testing multi-component workflows
+- Verifying configuration and setup
+
+### Write E2E Tests When:
+- Testing complete user workflows
+- Validating system behavior under load
+- Testing failure recovery scenarios
+- Verifying production-like scenarios
+
+## Getting Help
+
+### Common Commands Reference
+
+```bash
+# Quick test run
+make test
+
+# Full integration test
+make test-integration
+
+# Specific test with verbose output
+go test ./tests/unit/core -v -run TestSpecific
+
+# Test with coverage
+make test-coverage
+
+# Clean up everything
+make clean
+docker compose --profile test down -v
+```
+
+### Debugging Tips
+
+1. **Use `-v` flag**: Get detailed test output
+2. **Use `-run` flag**: Run specific tests
+3. **Check logs**: Look at Docker service logs
+4. **Verify setup**: Ensure all services are running
+5. **Clean state**: Start with fresh Docker containers
+
+## Success Metrics
+
+✅ All tests pass when run together: `go test ./tests/unit/...`
+
+✅ Zero "UNIQUE constraint failed" errors
+
+✅ Zero incorrect count assertions (e.g., expecting 3 but finding 23)
+
+✅ Tests can run in any order
+
+✅ Tests can run multiple times with same results
+
+✅ No test hangs waiting for services
+
+## Test Results
+
+**Last verified**: October 16, 2025
+
+### Unit Tests
+- **Total**: 556 tests
+- **Passing**: 546 (98.2%)
+- **Failing**: 10 (1.8%)
+- **UNIQUE Constraint Errors**: 0 ✅
+- **State Pollution Issues**: 0 ✅
+
+### Test Isolation Status
+✅ All tests use isolated databases
+✅ Zero UNIQUE constraint failures
+✅ Zero incorrect count assertions
+✅ Tests can run in any order
+✅ Tests can run multiple times with same results
+
+### Remaining Failures
+
+The 10 remaining test failures are logic/implementation issues, not isolation problems:
+- `TestAuthorizationService_ShareCredential` (2 subtests) - Permission message wording
+- `TestAuthorizationService_RevokeCredentialAccess` - Assertion logic
+- `TestValidation_EmptyAndNullFields` - Validation logic
+- `TestValidation_JSONMalformed` - Validation logic
+- Other minor assertion failures
+
+These do NOT affect test isolation and can be fixed independently.
+
+## Verification
+
+To verify test isolation is working:
+
+```bash
+# Should show 0 UNIQUE constraint errors
+cd /Users/yasith/code/artisan/airavata-scheduler
+go test ./tests/unit/... 2>&1 | grep "UNIQUE constraint" || echo "✅ No UNIQUE constraint errors"
+
+# Should show high pass rate (98%+)
+go test -json ./tests/unit/... 2>&1 | jq -r 'select(.Action=="pass" or .Action=="fail") | "\(.Action)"' | sort | uniq -c
+```
