6장. Managing administration roles and users

As an administrator of an OpenShift Dedicated cluster with Customer Cloud Subscriptions (CCS), you have access to the cluster-admin role. The user who created the cluster can add the cluster-admin user role to an account to have the maximum administrator privileges. These privileges are not automatically assigned to your user account when you create the cluster. While logged in to an account with the cluster-admin role, users have mostly unrestricted access to control and configure the cluster. There are some configurations that are blocked with webhooks to prevent destabilizing the cluster, or because they are managed in OpenShift Cluster Manager and any in-cluster changes would be overwritten. Usage of the cluster-admin role is subject to the restrictions listed in your Appendix 4 agreement with Red Hat. As a best practice, limit the number of cluster-admin users to as few as possible.

As an administrator of an OpenShift Dedicated cluster, your account has additional permissions and access to all user-created projects in your organization’s cluster. While logged in to an account with the dedicated-admin role, the developer CLI commands (under the oc command) allow you increased visibility and management capabilities over objects across projects, while the administrator CLI commands (under the oc adm command) allow you to complete additional operations.
