OpenShift Ansible

This repository contains Ansible roles and playbooks to install, upgrade, and manage OpenShift clusters.

Note: the Ansible playbooks in this repository require an RPM package that provides docker. Currently, the RPMs from dockerproject.org do not provide this requirement, though they may in the future. This limitation is being tracked by #2720.

Getting the correct version

When choosing an openshift release, ensure that the necessary origin packages are available in your distribution's repository. By default, openshift-ansible will not configure extra repositories for testing or staging packages for end users.

We recommend using a release branch. We maintain stable branches corresponding to upstream Origin releases, e.g.: we guarantee an openshift-ansible 3.2 release will fully support an origin 1.2 release.

The most recent branch will often receive minor feature backports and fixes. Older branches will receive only critical fixes.

In addition to the release branches, the master branch master branch tracks our current work in development and should be compatible with the Origin master branch (code in development).

Getting the right openshift-ansible release

Follow this release pattern and you can't go wrong:

Origin/OCP	OpenShift-Ansible version	openshift-ansible branch
1.3 / 3.3	3.3	release-1.3
1.4 / 3.4	3.4	release-1.4
1.5 / 3.5	3.5	release-1.5
3.X	3.X	release-3.x

If you're running from the openshift-ansible master branch we can only guarantee compatibility with the newest origin releases in development. Use a branch corresponding to your origin version if you are not running a stable release.
