Chapter 5. Pipelines CLI (tkn)
5.1. Installing tkn
Use the tkn
CLI to manage Red Hat OpenShift Pipelines from a terminal. The following section describes how to install tkn
on different platforms.
You can also find the URL to the latest binaries from the OpenShift Container Platform web console by clicking the ? icon in the upper-right corner and selecting Command Line Tools.
5.1.1. Installing Red Hat OpenShift Pipelines CLI (tkn) on Linux
For Linux distributions, you can download the CLI directly as a tar.gz
archive.
Procedure
Download the relevant CLI.
Unpack the archive:
$ tar xvzf <file>
-
Place the
tkn
binary in a directory that is on yourPATH
. To check your
PATH
, run:$ echo $PATH
5.1.2. Installing Red Hat OpenShift Pipelines CLI (tkn) on Linux using an RPM
For Red Hat Enterprise Linux (RHEL) version 8, you can install the Red Hat OpenShift Pipelines CLI (tkn
) as an RPM.
Prerequisites
- You have an active OpenShift Container Platform subscription on your Red Hat account.
- You have root or sudo privileges on your local system.
Procedure
Register with Red Hat Subscription Manager:
# subscription-manager register
Pull the latest subscription data:
# subscription-manager refresh
List the available subscriptions:
# subscription-manager list --available --matches '*pipelines*'
In the output for the previous command, find the pool ID for your OpenShift Container Platform subscription and attach the subscription to the registered system:
# subscription-manager attach --pool=<pool_id>
Enable the repositories required by Red Hat OpenShift Pipelines:
Linux (x86_64, amd64)
# subscription-manager repos --enable="pipelines-1.7-for-rhel-8-x86_64-rpms"
Linux on IBM Z and LinuxONE (s390x)
# subscription-manager repos --enable="pipelines-1.7-for-rhel-8-s390x-rpms"
Linux on IBM Power Systems (ppc64le)
# subscription-manager repos --enable="pipelines-1.7-for-rhel-8-ppc64le-rpms"
Install the
openshift-pipelines-client
package:# yum install openshift-pipelines-client
After you install the CLI, it is available using the tkn
command:
$ tkn version

5.2. Configuring the OpenShift Pipelines tkn CLI
Configure the Red Hat OpenShift Pipelines tkn
CLI to enable tab completion.
5.2.1. Enabling tab completion
After you install the tkn
CLI, you can enable tab completion to automatically complete tkn
commands or suggest options when you press Tab.
Prerequisites
-
You must have the
tkn
CLI tool installed. -
