[rdo-list] Multiple tools for deploying and testing TripleO

Mon Aug 1 17:07:02 UTC 2016

The vast majority of RDO's CI relies on using upstream
installation/deployment projects in order to test installation of RDO
packages in different ways and configurations.

Unless I'm mistaken, TripleO Quickstart was originally created as a
mean to "easily" install TripleO in different topologies without
requiring a massive amount of hardware.
This project allows us to test TripleO in virtual deployments on just
one server instead of, say, 6.

There's also WeIRDO [1] which was left out of your list.
WeIRDO is super simple and simply aims to run upstream gate jobs (such
as puppet-openstack-integration [2][3] and packstack [4][5]) outside
of the gate.
It'll install dependencies that are expected to be there (i.e, usually
set up by the openstack-infra gate preparation jobs), set up the trunk
repositories we're interested in testing and the rest is handled by
the upstream project testing framework.

The WeIRDO project is /very/ low maintenance and brings an exceptional
amount of coverage and value.
This coverage is important because RDO provides OpenStack packages or
projects that are not necessarily used by TripleO and the reality is
that not everyone deploying OpenStack on CentOS with RDO will be using
TripleO.

Anyway, sorry for sidetracking but back to the topic, thanks for
opening the discussion.

What honestly perplexes me is the situation of CI in RDO and OSP,
especially around TripleO/Director, is the amount of work that is
spent downstream.
And by downstream, here, I mean anything that isn't in TripleO proper.

I keep dreaming about how awesome upstream TripleO CI would be if all
that effort was spent directly there instead -- and then that all work
could bear fruit and trickle down downstream for free.
Exactly like how we keep improving the testing coverage in
puppet-openstack-integration, it's automatically pulled in RDO CI
through WeIRDO for free.
We make the upstream better and we benefit from it simultaneously:
everyone wins.
