Experimental Kubernetes Operator to automatically delete completed Jobs and their Pods. Controller listens for changes in Pods created by Jobs and deletes it on Completion.
Some defaults:
- All Namespaces are monitored by default
- Only Pods created by Jobs are monitored
# remember to change namespace in RBAC manifests for monitoring namespaces other than "default"
kubectl create -f https://raw.githubusercontent.com/lwolf/kube-cleanup-operator/master/deploy/rbac.yaml
# create deployment
kubectl create -f https://raw.githubusercontent.com/lwolf/kube-cleanup-operator/master/deploy/deployment.yaml
kubectl logs -f $(kubectl get pods --namespace default -l "run=cleanup-operator" -o jsonpath="{.items[0].metadata.name}")
# Use simple job to test it
kubectl create -f https://k8s.io/examples/controllers/job.yaml
