Red Hat OpenShift Container Platform

Removing the kubeadmin user

After you define an identity provider and create a new cluster-admin user, you can remove the kubeadmin to improve cluster security.

If you follow this procedure before another user is a cluster-admin, then Red Hat OpenShift Container Platform must be reinstalled. It is not possible to undo this command.

Prerequisites

You must have configured at least one identity provider.
You must have added the cluster-admin role to a user.
You must be logged in as an administrator.

Procedure

Remove the kubeadmin secrets:

$ oc delete secrets kubeadmin -n kube-system
