MacOS

This is actually a really quick process so this article is going to be short. This process will show you how to do the following:

• How to Install Brew for MacOS
• How to Install the OpenShift CLI using Brew
• How to Utilize the Login Command with Token to Access a Cluster

Step 1. Install Brew for MacOS

Run the following command to install brew in a terminal window:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Note: After you run the command there are some additional commands that will be asked to run in order to run brew. If this is not run successfully a command not found will display when running the brew command.

Step 2. Install the OpenShift CLI using Brew

Run the following command in the terminal to install the OpenShift (aka OC) CLI utility:

$ brew install openshift-cli

tar xvf openshift-client-linux.tar.gz oc kubectl
cp oc kubectl /usr/local/bin

oc version
kubectl version
/ocp-tools/openshift-install version

Install OC client in Ubuntu/Debian

Get the oc client download URL

Go to this link to get your desired version of the OC client tool. I have choosen the latest version available in July, 2020.

https://github.com/openshift/okd/releases/download/4.5.0-0.okd-2020-07-14-153706-ga/openshift-client-linux-4.5.0-0.okd-2020-07-14-153706-ga.tar.gz

Download the package

wget https://github.com/openshift/okd/releases/download/4.5.0-0.okd-2020-07-14-153706-ga/openshift-client-linux-4.5.0-0.okd-2020-07-14-153706-ga.tar.gz

Extract the package

tar -xvf openshift-client-linux-4.5.0-0.okd-2020-07-14-153706-ga.tar.gz

Move oc and kubectl file to your expected directory

sudo mv oc kubectl /usr/local/bin/

Now you can start using OC command

oc version

** You may need to add the installation path in your bash profile
