Microk8s test-environment deployment looks like pain in the ass

Hello,
I’m trying to deploy vault on a development-machine using microk8s to prepare deployment on production system (real kubernetes).

I’ve been struggling around through helm setup and docs now about 2 days and was happily even to see any web-ui once. But I’ve still not figured out why/how I can mount custom config directory and storage-directory.

Is there any real-world example on how to setup that? Any help welcome, but please no “bad comments” that won’t help anyone at all.

Thanks in advice.
