Support validation of ".spec.valuesFrom"

I would like to use hrval-action, but in my use case I am using ".spec.valuesFrom" to add values from Kubernetes secrets to application configuration. These values passed with "valuesFrom" are required in Helm chart so validation fails.

What I would propose is to have a separate directory with ConfigMaps and Secrets in the deployment repository where hrval-action would look for ConfigMaps and Secrets specified with ".spec.ValuesFrom". In my case - I will push Secrets with fake values and flux.weave.works/ignore set to "true" to this directory.

Additional steps would be:

  1. Read valuesFrom from HelmRelease
  2. Find files fitting valuesFrom configmap or secret
  3. Read values from file found in point 2 and move it to temp file
  4. Add multiple -f tempfile to helm template command

What do you think about it?

Bonus question:
Is other language then Bash acceptable for this project? I can see Docker image is using Go.

@stefanprodan What's your opinion on that? I may try to implement it if you think it makes sense for the project.

commented

Yes I think it makes sense 👍

As for the language, I think you could write GH actions in Go but I didn't had time to see what options are there.

Would be nice parser chartFileRef and use if exist. PR #32 covers it.

I have finally implemented this feature and created pull request #57 .
I hope it is still OK to use Go for this implementation as discussed earlier. I am not a Go developer and any feedback about the code is highly appreciated.
