go mod changes
YuniKorn scheduler shim for kubernetes is a customized k8s scheduler, it can be deployed in a K8s cluster and work as the scheduler. This project contains the k8s shim layer code for k8s, it depends on yunikorn-core which encapsulates all the actual scheduling logic. By default, it handles all pods scheduling if pod's spec has field schedulerName: yunikorn.
For detailed information on how to build the overall scheduler please see the build document in the yunikorn-site.
This component build should only be used for development builds. Prerequisites and build environment setup is described in the above mentioned build document.
The simplest way to get a local binary that can be run on a local Kubernetes environment is:
make build
This command will build a binary k8s_yunikorn_scheduler under _output/dev dir. This binary is executable on local environment, as long as kubectl is properly configured. Run ./k8s_yunikorn_scheduler -help to see all options.
Note: It may take few minutes to run this command for the first time, because it needs to download all dependencies. In case you get an error relating to checksum mismatch, run go clean -modcache and then rerun make build.
If the local kubernetes environment is up and running you can build and run the binary via:
make run
This will build the code, and run the scheduler with verbose logging. It will set the configuration for the scheduler to the provided default configuration queues.yaml and uses the current setup for kubernetes.
Unit tests for the shim only can be run via:
make test
Any changes made to the shim code should not cause any existing tests to fail.
Build docker image can be triggered by running following command.
make image
You can set DOCKER_ARCH, REGISTRY and VERSION in the commandline to build docker image with a specified arch, tag and version. For example,
make image DOCKER_ARCH=amd64 REGISTRY=yunikorn VERSION=latest
This command will build an amd64 binary executable with version latest and the docker image tag is yunikorn/yunikorn:scheduler-amd64-latest. If not specified, DOCKER_ARCH defaults to the build host‘s architecture. For example, the Makefile will detect if your host’s architecture is i386, amd64, arm64v8 or arm32v7 and your image would be tagged with the corresponding host architecture (i.e. yunikorn:scheduler-arm64v8-latest if you are on an M1).
You can run following command to retrieve the meta info for a docker image build, such as component revisions, date of the build, etc.
docker inspect --format='{{.Config.Labels}}' yunikorn/yunikorn:scheduler-amd64-latest
