Helm in Practice

Viewing Release

Since we installed WordPress and then upgraded it, we can view the release information using the helm list or helm ls command. The general syntax is:

helm list
# or
helm ls

If our release is in a different namespace than default, we must specify the namespace using the --namespace or -n flag:

helm list -n [NAMESPACE]
# or
helm ls -n [NAMESPACE]

Otherwise, to list all releases in all namespaces, use the --all-namespaces or -A flag:

helm ls -A

The helm ls command should show that we have at least two revisions of the release.

You can also use the filter flag (--filter) to filter the releases based on a regular expression pattern. For example, to list all releases in all namespaces that have the my prefix:

helm ls --filter 'my' -A
