[rdo-users] Quickstart and containers

[Dan Prince]

HI James,

Not for an "overcloud" I think. But you could check out some of the
work we did in Pike, Queens, and now Rocky for the new containerized
undercloud. See the upstream docs here:

https://docs.openstack.org/tripleo-docs/latest/install/containers_deployment/undercloud.html

There are two ways to approach it:

One is 'undercloud deploy' which is an experimental interface that
lets you interact with the heat templates to drive a single node
installation much like you would when creating an Overcloud.

The second approach which we are actively building is a command which
will consume the same undercloud.conf that instack-undercloud uses to
drive the same installer framework that 'undercloud deploy' provides.

Quickstart has some playbooks that can drive 'undercloud_deploy'...
but I think we are switching it over to 'undercloud install'
exclusively. So if either one suits your needs you might be able to
get quickstart to do this all for you on a single node as well.

We've got lots of ideas on how to improve the single node use case in
the future BTW. Hoping to prototype some things at the upcoming PTG in
Dublin.
