Kubernetes Operator to automatically delete completed Jobs and their Pods

Kubernetes cleanup operator

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

Usage

# 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
