The multi-cluster-app-dispatcher is a Kubernetes controller providing mechanisms for applications to manage batch jobs in a single or multi-cluster environment.
The multi-cluster-app-dispatcher (MCAD) controller is capable of (i) providing an abstraction for wrapping all resources of the job/application and treating them holistically, (ii) queuing job/application creation requests and applying different queuing policies, e.g., First In First Out, Priority, (iii) dispatching the job to one of multiple clusters, where a MCAD queuing agent runs, using configurable dispatch policies, and (iv) auto-scaling pod sets, balancing job demands and cluster availability (future work).
Follow the build instructions here to build the Multi-Cluster-App-Dispatcher controller.
Refer to deployment instructions here on how to deploy the multi-cluster-app-dispatcher as a controller in Kubernetes.
-
Update version in CONTROLEER_VERSION file to the new release version.
-
Once CONTROLLER_VERSION file change merged , create the release branch against the main as
release-<version>. -
The release branch then trigger the image build/push pipeline and push the image to mcad-controller quay repository with specified release version tag.
-
Create a new release on Releases page by creating a tag with same value as in CONTROLLER_VERSION file formatted (with v prefix) , provide proper release title and description.
-
The latest release changes should also reflect in the mcad go package module.
