Installation

This guide walks you through the installation process of setting up a Red Hat OpenShift cluster in Z. Each step is crucial to ensure a smooth and successful deployment

Steps to Install OpenShift

1. Step 1: Install KVM Hypervisor
   • Install the KVM hypervisor, which is necessary for creating and managing virtual machines that will run the OpenShift cluster components.
2. Step 2: Prepare Network Configuration
   • Configure the network settings to ensure proper communication between the cluster nodes and other network resources.
3. Step 3: Prepare Load Balancer VM
   • Set up a virtual machine to act as a load balancer, distributing traffic among the OpenShift cluster nodes for improved reliability and performance.
4. Step 4: Prepare the Red Hat OpenShift Cluster
   • Initialize the OpenShift cluster setup, configuring the necessary parameters and settings.
5. Step 5: Create Bootstrap Node
   • Create and configure the bootstrap node, which helps in bootstrapping the OpenShift cluster during installation.
6. Step 6: Create the Control Plane Nodes (Master Nodes)
   • Set up the control plane nodes (master nodes) that will manage the OpenShift cluster operations and orchestration.
7. Step 7: Create the Compute Plane Nodes (Worker Nodes)
   • Add the compute plane nodes (worker nodes) to the cluster, where application workloads will be deployed and run.
8. Step 8: Check for CSR Requests
   • Review and approve the Certificate Signing Requests (CSRs) from the cluster nodes to ensure secure communication within the cluster.
9. Step 9: Access Web UI
   • Access the OpenShift web console to manage and monitor the cluster through a graphical user interface.
10. Certificate Installation
    • Install and configure the necessary certificates to secure the OpenShift cluster and its communications.
