POC - Offline Helm Schema Validation

[shaun-nx]

Questions to answer, and things to consider, during this POC

• Is it enough to use our Operator when deploying in an offline environment?
  • The Operator does not enable this use case, see comments
• Are there other Helm charts out there that have solved this issue?
• Can we solve the relative path issue? See Relative filesystem schema references in values.schema.json broken helm/helm#10481

Outcomes

• Determine if offline helm schema validation is feasible
• Document discoveries

Hi @shaun-nx thanks for reporting!

Be sure to check out the docs and the Contributing Guidelines while you wait for a human to take a look at this 🙂

Cheers!

Refinement Log:
May not be possible since Helm does not allow for relative paths.

offline using operator runs into imagePullBackOff on operator itself and a dependency quay.io/brancz/kube-rbac-proxy:
