Root Cause

Helm upgrade fails because the provided values.yaml is missing required keys that the chart template expects, often due to a new chart version with additional required fields.

Workarounds

  1. 90% success Inspect the chart for required values: `helm show values <chart-name>` and compare with your values.yaml. Add missing keys, e.g., if the chart requires `service.port`, add `service: {port: 8080}` to your values file.

  1. Inspect the chart for required values: `helm show values <chart-name>` and compare with your values.yaml. Add missing keys, e.g., if the chart requires `service.port`, add `service: {port: 8080}` to your values file.
  2. Use `helm upgrade --install --dry-run --debug` to see the template rendering errors and identify exactly which values are missing.

Dead Ends

Common approaches that don't work:

  1. Run `helm upgrade --reuse-values` to reuse old values 95% fail

    Reusing old values doesn't supply the missing required keys from the new chart version. It will still fail with the same error.

  2. Delete the release and reinstall with `helm install` 80% fail

    Deleting the release may cause data loss (e.g., PVCs may be orphaned). Also, the install will fail for the same reason if values are missing.
