GUIDE: Install OpenShift 4 — The Easy Way — Part 2

In Part 1 of this guide we install a three-node OCP 4.7 cluster using the assisted installer. In Part 2 we will:

• Download and configure the oc client
• Setup an authentication provider using htpasswd
• Configure the registry (non-production)
• Create an ephemeral Drupal project.

Download the oc client:

Browse to https://mirror.openshift.com/pub/openshift-v4/x86_64/clients/ocp/stable/ and download the client appropriate for your system.

For Linux clients, wget the client tar file, extract the client tar file, and move the kubectl and oc executables to /usr/local/bin:

wget https://mirror.openshift.com/pub/openshift-v4/x86_64/clients/ocp/stable/openshift-client-linux.tar.gz
tar -zxvf openshift-client-linux.tar.gz
sudo mv kubectl/usr/local/bin/

Test the oc client:

Download the kubeconfig for your cluster from cloud.redhat.com:

Set the KUBECONFIG environment variable and test the connection:

export KUBECONFIG=~/Downloads/kubeconfig
oc get nodes

Running ‘oc get nodes’ should return the information pictured above.

Setup an authentication provider using htpasswd:

The kubeadmin user is not for permanent use, instead you should setup other means of authentication. The easiest way to set up a local user is with htpasswd. Create the users.htpasswd using the following command for testuser:

htpasswd -c -B users.htpasswd testuser

Create a secret in the openshift-config project using the users.htpasswd file you generated:

oc create secret…
