Administrator cli Operations

Overview

This topic provides information on the administrator cli operations and their syntax. You must setup and login with the cli before you can perform these operations.

The openshift command is used for starting services that make up the OpenShift Container Platform cluster. For example, openshift start [master|node]. However, it is also an all-in-one command that can perform all the same actions as the oc and oc adm commands via openshift cli and openshift admin respectively.

The administrator cli differs from the normal set of commands under the developer cli, which uses the oc command, and is used more for project-level operations.

Common Operations

The administrator cli allows interaction with the various objects that are managed by OpenShift Container Platform. Many common oc adm operations are invoked using the following syntax:

$ oc adm <action> <option>

This specifies:

  • An <action> to perform, such as new-project or groups.

  • An available <option> to perform the action on as well as a value for the option. Options include --output.
