OpenShift Ansible

This repository contains Ansible roles and playbooks for OpenShift clusters.

Previous OpenShift Ansible 3.x releases

For 3.x releases of OpenShift Ansible please reference the release branch for specific versions. The last 3.x release is 3.11 release.

OpenShift 4.x

Installation of OpenShift 4.x uses a command-line installation wizard instead of Ansible playbooks. Learn more about the OpenShift Installer in this overview.

For OpenShift 4.x, this repo only provides playbooks necessary for scaling up an existing 4.x cluster with RHEL hosts.

The master branch tracks our current work in development.

Requirements:

• Ansible >= 2.7.8

Quickstart

Install an OpenShift 4.x cluster

Install a cluster using the OpenShift Installer.

Inventory
