Deploy Hugegraph server with docker

Note:
The docker image of hugegraph is a convenience release, not official distribution artifacts from ASF. You can find more details from ASF Release Distribution Policy.
Recommand to use release tag(like 1.2.0) for the stable version. Use latest tag to experience the newest functions in development.

1. Deploy

We can use docker to quickly start an inner HugeGraph server with RocksDB in background.

Using docker run
Use docker run -itd --name=graph -p 8080:8080 hugegraph/hugegraph to start hugegraph server.
Using docker compose
Certainly we can only deploy server without other instance. Additionally, if we want to manage other HugeGraph-related instances with server in a single file, we can deploy HugeGraph-related instances via docker-compose up -d. The docker-compose.yaml is as below:
```
version: '3'
services:
  graph:
    image: hugegraph/hugegraph
    ports:
      - 8080:8080
```

2. Create Sample Graph on Server Startup

If you want to pre-load some (test) data or graphs in container(by default), you can set the env PRELOAD=ture

If you want to customize the pre-loaded data, please mount the the groovy scripts (not necessary).

Using docker run
Use docker run -itd --name=graph -p 8080:8080 -e PRELOAD=true -v /path/to/yourScript:/hugegraph/scripts/example.groovy hugegraph/hugegraph to start hugegraph server.

Using docker compose

We can also use docker-compose up -d to quickly start. The docker-compose.yaml is below. example.groovy is a pre-defined script. If needed, we can mount a new example.groovy to preload different data:

version: '3'
services:
  graph:
    image: hugegraph/hugegraph
    environment:
      - PRELOAD=true
    volumes:
      - /path/to/yourscript:/hugegraph/scripts/example.groovy
    ports:
      - 8080:8080

Using start-hugegraph.sh
If you deploy HugeGraph server without docker, you can also pass arguments using -p, like this: bin/start-hugegraph.sh -p true.

3. Enable Authentication

Using docker run
Use docker run -itd --name=graph -p 8080:8080 -e AUTH=true -e PASSWORD=123456 hugegraph/hugegraph to enable the authentication and set the password with -e AUTH=true -e PASSWORD=123456.

Using docker compose

Similarly, we can set the envionment variables in the docker-compose.yaml:

version: '3'
services:
  server:
    image: hugegraph/hugegraph
    container_name: graph
    ports:
      - 8080:8080
    environment:
      - AUTH=true
      - PASSWORD=123456
