Question 1

What is the difference between `helm install` and `helm upgrade` when the `--force` flag is used?

Accepted Answer

--force deletes and re-creates resources that cannot be patched in place

Answer

`--force` causes Helm to delete and recreate resources that fail a standard patch/update, useful when resource specs have immutable fields that changed.

Question 2

How can you override a nested value in values.yaml from the `helm install` command line?

Accepted Answer

--set parent.child=value

Answer

`--set` accepts dot-notation paths such as `parent.child=value` to override nested keys in values.yaml without editing the file.

Question 3

What is an OCI registry in the context of Helm charts?

Accepted Answer

A container image registry used to store and distribute Helm charts as OCI artifacts

Answer

Helm supports storing charts in OCI-compliant registries (like Docker Hub or ECR) as artifacts, using `helm push` and `helm pull oci://` references.

Question 4

Which Helm command packages a chart directory into a versioned `.tgz` archive for distribution?

Accepted Answer

helm package

Answer

`helm package` compresses a chart directory into a `-.tgz` tarball that can be uploaded to a chart repository or OCI registry.

Question 5

What is the purpose of the `NOTES.txt` file in a Helm chart's `templates/` directory?

Accepted Answer

Rendered and displayed to the user after a successful install or upgrade

Answer

`NOTES.txt` is a template rendered after install/upgrade and printed to the user's terminal, typically containing usage instructions or next steps.
