Chapter 6. Deleting Operators from a cluster
The following describes how to delete Operators from a cluster using either the web console or the CLI.
6.1. Deleting Operators from a cluster using the web console
Cluster administrators can delete installed Operators from a selected namespace by using the web console.
Prerequisites
-
Access to an OpenShift Container Platform cluster web console using an account with
cluster-admin
permissions.
Procedure
-
From the Operators
Installed Operators page, scroll or type a keyword into the Filter by name to find the Operator you want. Then, click on it. On the right-hand side of the Operator Details page, select Uninstall Operator from the Actions drop-down menu.
An Uninstall Operator? dialog box is displayed, reminding you that Removing the operator will not remove any of its custom resource definitions or managed resources. If your operator has deployed applications on the cluster or configured off-cluster resources, these will continue to run and need to be cleaned up manually.
The Operator, any Operator deployments, and Pods are removed by this action. Any resources managed by the Operator, including CRDs and CRs are not removed. The web console enables dashboards and navigation items for some Operators. To remove these after uninstalling the Operator, you might need to manually delete the Operator CRDs.
- Select Uninstall. This Operator stops running and no longer receives updates.
6.2. Deleting Operators from a cluster using the CLI
Cluster administrators can delete installed Operators from a selected namespace by using the CLI.
