tripleo-quickstart-extras/roles/overcloud-prep-containers

overcloud-prep-containers

This role that prepares an environment for a containerized compute is under active development along with active development of the containerized computer feature itself.

This role walks through the developer setup for a tripleo deployment with a containerized compute. The developer documentation can be found here: https://etherpad.openstack.org/p/tripleo-containers-work

The instructions below use the master branch from delorean that has been vetted by CI, and then updates any tripleo rpm to the latest version available from delorean. It should be the same content as what currently runs in tripleo-ci

This also git checks out https://opendev.org/openstack/tripleo-heat-templates with refspec: refs/changes/59/330659/43 , this can be updated in config/general_config/containers_minimal.yml
