Chapter 5. Administrator CLI Operations
5.1. Overview Copia collegamentoCollegamento copiato negli appunti!
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 oadm
command is used for administrator CLI operations, which is a symlink that can be used on hosts that have the openshift
binary, such as a master. If you are on a workstation that does not have the openshift
binary, you can also use oc adm
in place of oadm
, if oc
is available.
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.
5.2. Common Operations Copia collegamentoCollegamento copiato negli appunti!

operations are invoked using the following syntax:
oadm <action> <option>
$ oadm <action> <option>
This specifies:

An
<action>
to perform, such asnew-project
orrouter
. -
An available
<option>
to perform the action on as well as a value for the option. Options include--output
.
