💡 Hint

Common Mistakes

Using 'delete' instead of 'install' will remove a release, not install it.

Using 'update' is not a valid Helm command for installing charts.

Using 'create' generates a new chart skeleton locally, but does not install it into the cluster.

The helm install command is used to install a Helm chart into your Kubernetes cluster.

💡 Hint

Common Mistakes

Using 'status' shows details of a single release, not all releases.

Using 'search' looks for charts in repositories, not installed releases.

Using 'install' will fail if the release already exists.

Using 'delete' removes the release instead of updating it.

Using 'rollback' reverts to a previous version, not upgrade.

The helm upgrade command updates an existing release with a new chart or configuration.

💡 Hint

Common Mistakes

Using 'install' instead of 'create' will try to deploy a chart, not create one.

Using 'delete' removes a release, not create a chart.

Fill all four blanks to define a Helm values override file usage in the install command.

C--set

DreplicaCount=3

Attempts:

💡 Hint

Common Mistakes

Using '--set' without a key=value pair causes an error.

Using '--values' without a file name causes an error.

Mixing up the order of options can cause unexpected behavior.

Use --values followed by a file name to override default values, and --set to override specific values inline.
