Installation and Verification

The method of installation that you shall be using for this session would be the 'Advanced Installation' method which uses Ansible playbooks for automating the installation of OpenShift Container Platform cluster (version 3.5). The host preparation and prerequisites needed for the installation have already been done.

Step 1. Examining the provided Ansible inventory file - Let us start by examining the Ansible inventory files which contains the host information. To perform the further steps, you will need to run the commands on the 'master' host.

Application Management Basics

Topic 1 - To deploy a sample application (Explain Pod, Services, Routes, DCs, BCs, PV, PVCs (CNS))

In this module,you would deploy a sample application using the 'oc' tool and go through some features like pods, services, routes, etc.

We would deploy a sample application from a DockerHub image.
