Uninstalling the WordPress release

Uninstalling a Helm release means deleting the Kubernetes resources that it manages. In addition, the uninstall command deletes the release's history. While this is often what we want, specifying the --keep-history flag will instruct Helm to retain the release history.

The syntax for the uninstall command is very simple:

helm uninstall RELEASE_NAME [...] [flags]

Uninstall the WordPress release by running the helm uninstall command:

$ helm uninstall wordpress -n chapter3

Once uninstalled, you will see the following message:

release 'wordpress' uninstalled

You will also notice that the wordpress release no longer exists in the chapter3 namespace:

$ helm list -n chapter3

The output will be an empty table. You can also confirm that the release is no longer present by attempting to use kubectl to get the WordPress deployments:

$ kubectl get deployments -l app=wordpress -n chapter3
No resources found in chapter3...
