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
