[Zlopez]

This is the debug process I'm using when testing the CRD for koji-builder.

• Run molecule converge -s test-local
• docker ps and look for kind-test-local
• docker exec -it <container_id> bash
• kubectl get namespace and look for the correct namespace
• Switch to correct namespace kubectl config set-context --current --namespace=<namespace>
• Get logs of the ansible kubectl logs <pod> ansible

This will be added to the documentation once somebody start to work on this issue.
