Common Mistakes

Using the release name instead of the chart path.

Trying to fill a value for the image tag blank that doesn't exist.

💡 Hint

Common Mistakes

Using 'replicas' or 'count' instead of 'replicaCount'.

Using an incorrect chart path.

The first blank is the chart path './chart'. The second blank is the correct Helm value key 'replicaCount' to set the number of replicas.

💡 Hint

Common Mistakes

Using a different release name in the status command.

Using 'myapp-release' instead of 'myapp'.

Using 'status' as a release name.

The rollback command needs the release name 'myapp' and the revision number '1'. The status command should check the same release 'myapp'.
