Command line tool usage

Rahti can be used via the command line either with OpenShift's oc tool or with the kubectl tool from Kubernetes. Certain features specific to OpenShift are only available when using the oc tool.

The "Command Line Tools" page in the OpenShift web UI

The information for downloading the oc tool and logging in from the command line can be found in the "Command Line Tools" page in the web interface. After logging in to the web interface, you can find the page here:

Command line tools

The oc tool is a single binary that just needs to be placed in your path. You can find the oc command to login in one the fields on the page. There is a button next to it to copy the command to the clipboard:

Copy the command and paste it into a terminal to start using OpenShift via the command line.


If you open multiple terminals, the login session for oc will be active in all of them.
