OpenShift Installation and Configuration Management

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 or upgrading RHEL hosts in an existing 4.x cluster.

The master branch tracks our current work in development.

Requirements: (localhost)

• Ansible >= 2.9.5
• OpenShift Client (oc)

Quickstart

Install an OpenShift 4.x cluster

Install a cluster using the OpenShift Installer.

Create an Ansible Inventory

Create an inventory file with the appropriate groups and variables defined. An example inventory can be found in inventory/hosts.example.

Required variables include:

• openshift_kubeconfig_path - Path to the kubeconfig for the cluster

Run the RHEL node scaleup playbook

cd openshift-ansible
ansible-playbook -i inventory/hosts playbooks/scaleup.yml

Run the RHEL node upgrade playbook

Custom tasks can be performed during upgrades at different stages of the upgrade. See the hooks documentation for more information.

cd openshift-ansible
ansible-playbook -i inventory/hosts playbooks/upgrade.yml
