Deploying a Babylon OpenShift Container Platform (including the Babylon Operators)

Overview

This document outlines deploying the OpenShift Container Platform cluster to be used for the Babylon project.

A Babylon OpenShift Container Platform cluster is an AgnosticD Config with the necessary vars outlined below.

Pre-requisites

  • A host capable and configured for running Ansible

  • AWS Credentials

Step 1 - Creating your Own Babylon OpenShift Container Platform

  1. If necessary clone or pull AgnosticD

    $ git clone https://github.com/redhat-cop/agnosticd.git

  2. Change directory into agnosticd/ansible

    cd agnosticd/ansible

Preparing the Vars files(s)

The typical way to deploy an AgnosticD config from a control host, or laptop, is to invoke it with 1, or ideally 2, var files.

Note
 It is recommeded that you use 2 var files to seperate confidential information such as creds from configuration inofrmation which can be shared freely. That is the pattern we will use here: 
 ansible-playbook main.yml \
-e @~/install-vars.yml \
-e @~/secret-vars.yml
Prepare the yaml based variable files
