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://raw.githubusercontent.com/kubernetes/kubernetes.github.io/master/docs/concepts/workloads/controllers/job.yaml
