OpenShift Ansible

This repo contains Ansible code for OpenShift. This repo and the origin RPMs that it installs currently require a package that provides docker. Currently the RPMs provided from dockerproject.org do not provide this requirement, though they may in the future.

Branches and tags

The master branch tracks our current work and should be compatible with both Origin master branch and the most recent Origin stable release. Currently that's v1.4 and v1.3.x. In addition to the master branch, we maintain stable branches corresponding to upstream Origin releases, e.g.: release-1.2. The most recent branch will often receive minor feature backports and fixes. Older branches will receive only critical fixes.

Releases are tagged periodically from active branches and are versioned 3.x corresponding to Origin releases 1.x. We unfortunately started with 3.0 and it's not practical to start over at 1.0.
