API impersonation
Impersonating the system:admin user
Impersonating the system:admin group

API impersonation

You can configure a request to the OpenShift Container Platform API to act as though it originated from another user. For more information, see User impersonation in the Kubernetes documentation.

You can grant a user permission to impersonate system:admin, which grants them cluster administrator permissions.

Procedure

To grant a user permission to impersonate system:admin, run the following command:

$ oc create clusterrolebinding <any_valid_name> --clusterrole=sudoer --user=<username>

Impersonating the system:admin group

When a system:admin user is granted cluster administration permissions through a group, you must include the --as=<user> --as-group=<group1> --as-group=<group2> parameters in the command to impersonate the associated groups.

Procedure

To grant a user permission to impersonate a system:admin by impersonating the associated cluster administration groups, run the following command:
```
$ oc create clusterrolebinding <any_valid_name> --clusterrole=sudoer --as=<user> \
--as-group=<group1> --as-group=<group2>
```
