Preparing for the installation

As you have seen in the previous sections, the prerequisites are very important, and any mistake could be an Achilles' heel for the OpenShift cluster installation and functioning. Failure to prepare the prerequisites correctly will cause errors during the cluster deployment that are not always easy to troubleshoot to find the root cause. That said, we would like to stress the importance of preparing and validating the pre-requisites correctly before starting the cluster deployment.

To start the installation using the UPI method, you will need the following:

• An SSH key pair
• A pull secret for the cluster, which you can generate by accessing https://console.redhat.com/openshift/install, with a valid user subscription
• OpenShift installer binary
• OpenShift command-line tools
• Installation configuration file (install-config.yaml)

In the following sections, we will detail all of those steps.
