INSTALLING OPENSHIFT ON AWS: A GUIDE

Setting Up OpenShift on AWS

Installing OpenShift on AWS involves several steps to ensure a successful deployment. Below is a comprehensive guide to help you through the process.

Prerequisites

• AWS account with sufficient permissions to create resources.

• OpenShift Installer (download from the official website).

• Command-line interface (CLI) tools installed (AWS CLI, oc CLI).

• Access to a terminal or command prompt.

Step 1: Configure AWS CLI

Before starting the installation, configure your AWS CLI with the necessary credentials.

aws configure

Step 2: Set Up IAM Roles and Policies

Create IAM roles and policies that allow OpenShift to manage resources on AWS.

• Create a role for the OpenShift installer with appropriate permissions.

• Attach policies for EC2, VPC, IAM, and other necessary services.

Step 3: Prepare the OpenShift Installation Configuration

Generate an installation configuration file using the OpenShift installer.

openshift-install create install-config

Fill in the required information such as:

• Cluster name

• Base domain

• Region

• Pull secret

Step 4: Create the OpenShift Cluster

Once the configuration file is ready, initiate the cluster creation process.

Step 5: Access the OpenShift Console

After the installation is complete, access the OpenShift web console using the provided URL.

• Use the credentials generated during the installation.

Step 6: Verify the Installation

Check the status of the OpenShift cluster and ensure all components are running properly.

Step 7: Configure Networking and Security

Set up networking and security groups to control access to your OpenShift cluster.

• Configure security groups for EC2 instances.

• Set up load balancers if necessary.

Conclusion

By following these steps, you should have a fully functional OpenShift cluster running on AWS. Be sure to monitor the cluster and optimize resources as needed.
