Explanation Step 1: Clone the repository containing the NGINX configuration file (nginx.conf) to the local file system on the worker node that have Nginx Pod and Container

Step 2: Update the ConfigMap in OpenShift with the new nginx.conf. This involves deleting the old ConfigMap and creating a new one with the updated file.

Step 3: Delete the NGINX pods to force them to restart. The Deployment controller will automatically recreate the pods, and the new pods will use the updated ConfigMap.

By following these steps, you ensure that your NGINX configuration in OpenShift is updated and applied correctly.
