Registered by Dan Prince on 2016-08-04

Deploy the undercloud with Heat instead of elements. This will allow us to use composable services for the Undercloud as well.

Whiteboard

[2017-12-08] The various patches have been merged. I believe this is implemented and further work is being done with the containerized undercloud. Marking this one as implemented. If it is not done, let's update the status and move this out to Rocky.

-------------------------
Although we've had good progress on this in late Ocata and Pike I don't think we'll finish the feature in Pike unless someone else picks this up. Remaining work items are:

-full feature parity with instack. This includes landing t-h-t with:
  1) Ironic inspector:
  2) TripleO UI
  3) various undercloud features around SSL, docker registries, etc.

-building new 'openstack undercloud install' feature that drives 'openstack undercloud deploy' via undercloud.conf (a config file driven installer).

Lots of testing, etc.
