💡 Hint

Common Mistakes

Using '--name' flag which is deprecated.

Using '--chart' flag incorrectly.

The release name is given as a positional argument before the chart path, so you just provide the name directly without a flag.

💡 Hint

Common Mistakes

Using default 'values.yaml' instead of custom 'myvalues.yaml'.

Confusing release name with chart name.

The first argument is the chart directory or name, here 'mychart'. The -f flag specifies the custom values file, here 'myvalues.yaml'.

5fill in blank

Fill all three blanks to create a Helm values file snippet that sets the container image repository, tag, and pull policy.

  repository: [1]
  tag: [2]
  pullPolicy: [3]

A"nginx"

C"IfNotPresent"

D"Always"

💡 Hint

Common Mistakes

Using pullPolicy 'Always' which forces image pull every time.

Omitting quotes around strings.

The repository is the image name, here 'nginx'. The tag is the version, here '1.21.0'. The pull policy controls when Kubernetes pulls the image, here 'IfNotPresent' means only pull if not already present.
