List all resources in a namespace
A couple of times I needed to check what resources where still in a namespace, to understand why the namespace was still deleting after a while.
The kubectl get all -n namepace-name does not show all the resources so I found in internet this clever little command to show everything:
kubectl api-resources \
--verbs=list \
--namespaced -o name | xargs -n 1 kubectl get \
--ignore-not-found \
--show-kind \
-n namespace-nameIt takes a bit, but it does the job!
