Tutorial: Creating an admin user

edit

Creating an administration (admin) user allows you to access your cluster quickly. Follow these steps to create an admin user.

An admin user works well in this tutorial setting. For actual deployment, use a formal identity provider to access the cluster and grant the user admin privileges.

  1. Run the following command to create the admin user:

    rosa create admin --cluster=<cluster-name>
    Example output
    W: It is recommended to add an identity provider to login to this cluster. See 'rosa create idp --help' for more information.
I: Admin account has been added to cluster 'my-rosa-cluster'. It may take up to a minute for the account to become active.
I: To login, run the following command:
oc login https://api.my-rosa-cluster.abcd.p1.openshiftapps.com:6443 \
--username cluster-admin \
--password FWGYL-2mkJI-00000-00000

  2. Copy the log in command returned to you in the previous step and paste it into your terminal. This will log you in to the cluster using the CLI so you can start using the cluster.

    $ oc login https://api.my-rosa-cluster.abcd.p1.openshiftapps.com:6443 \
>    --username cluster-admin \
>    --password FWGYL-2mkJI-00000-00000
    Example output
    Login successful.

You have access to 79 projects, the list has been suppressed. You can list all projects with ' projects'

Using project "default".

  3. To check that you are logged in as the admin user, run one of the following commands:

    • Option 1:

      $ oc whoami
      Example output
      cluster-admin

    • Option 2:

      oc get all -n openshift-apiserver

      Only an admin user can run this command without errors.

  4. You can now use the cluster as an admin user, which will suffice for this tutorial. For actual deployment, it is highly recommended to set up an identity provider, which is explained in the next tutorial.
