`helm dependency update` resolves and downloads chart dependencies declared in the `dependencies` section of Chart.yaml into the `charts/` directory.

Question 2

Which Helm built-in object provides access to Kubernetes cluster version information in templates?

Accepted Answer

.Capabilities

Answer

The `.Capabilities` object exposes information about the Kubernetes cluster, including API versions and the Kubernetes version.

Question 3

What does a `helm rollback` command do when given a release name and revision number?

Accepted Answer

Restores the release to the specified previous revision

Answer

`helm rollback ` restores a Helm-managed release to a previously deployed revision stored in the release history.

Question 4

In Helm, what is the function of the `_helpers.tpl` file inside a chart's `templates/` directory?

Accepted Answer

Contains reusable named templates and helper functions

Answer

`_helpers.tpl` is a convention file prefixed with an underscore so Helm skips rendering it as a manifest; it holds reusable named templates called via `template` or `include`.

Question 5

Which command would you use to see the actual Kubernetes manifests Helm would generate without deploying them?

Accepted Answer

helm template

Answer

`helm template` renders chart templates locally and prints the resulting Kubernetes manifests without contacting the cluster.
