Error: unable to get pod logs for helm test myproject --logs

Question

I'm not sure if it's a bug from helm (using version 3.0.2) or a problem of config from me.

When I launch helm test command with --logs option, I receive an error before the end of the tests (tests which are ok, with normal logs, as I can read with kubectl logs).

Test pod is "not found", because it has a specific name like "myproject-django-test-tjbhc" (unlike job which is correctly named as expected).

$ helm test $RELEASE --logs --namespace $NAMESPACE

This seems to be a bug in Helm 3. I have created an issue on GitHub for this - lets see what happens to it.

As a temporary fix, you can stop your tests Pods from getting deleted by annotating your test Pods with:

"helm.sh/hook-delete-policy": before-hook-creation
