tripleo-quickstart was proposed to upstream TripleO as a replacement for the
virtual environment setup done by instack-virt-setup. 3rd party CI would be
used to gate tripleo-quickstart so that we'd be sure the virt setup was always
working. That was the extent of the CI scope defined in the spec. That work is
not yet completed (see work items in the spec).

Now it seems it is a much more all encompassing CI/automation/testing project
that is competing in scope with tripleo-ci itself.

IMHO you are correct here.  There has been quite a bit of discussion about removing the parts
of oooq that are outside of the original blueprint to replace instack-virt-setup w/ oooq.   As usual there are many different opinions here.  I think there are a lot of RDO guys that would prefer a lot of the native oooq roles stay where they are,  I think that is short sighted imho.  I agree that anything outside of the blueprint be removed from oooq.  This would hopefully allow the upstream to be more comfortable with oooq and allow us to really start consolidating tools.

Luckily for the users that still want to use oooq as a full end-to-end solution the 3rd party roles can be used even after tearing out these native roles.
 

I'm all for consolidation of these types of tools *if* there is interest.

Roll call.. is there interest?   +1 from me.
 

However, IMO, incubating these things downstream and then trying to get them
upstream or get upstream to adopt them is not ideal or a good example. The same
topic came up and was pushed several times with khaleesi, and it just never
happened, it was continually DOA upstream.

True, however that could be a result of the downstream perceiving barriers ( real or not ) in incubating projects in upstream openstack.   
 

I think it would be fairly difficult to get tripleo-ci to wholesale adopt
tripleo-quickstart at this stage. The separate irc channel from #tripleo is not
conducive to consolidation on tooling and direction imo.

The irc channel is easily addressed.  We do seem to generate an awful amount of chatter though :)
 

The scope of quickstart is actually not fully understood by myself. I've also
heard from some in the upstream TripleO community as well who are confused by
its direction and are facing similar difficulties using its generated bash
scripts that they'd be facing if they were just using TripleO documentation
instead.

The point of the generated bash scripts is to create rst documentation and reusable scripts for the end user.  Since the documentation and the generated scripts are equivalent I would expect the same errors, problems and issues.  I see this as a good thing really.  We *want* the CI to hit the same issues as those who are following the doc. 
 

I do think that this sort of problem lends itself easily to one off
implementations as is quite evidenced in this thread. Everyone/group wants and
needs to automate something in a different way. And imo, none of these tools
are building end-user or operator facing interfaces, so they're not fully
focused on building something that "just works for everyone". Those interfaces
should be developed in TripleO user facing tooling anyway
(tripleoclient/openstackclient/etc).

So, I actually think it's ok in some degree that things have been automated
differently in different tools. Anecdotally, I suspect many users of TripleO in
production have their own automation tools as well. And none of the
implementations mentioned in this thread would likely meet their needs either.

This is true..  without a tool in the upstream that addresses ci, dev, test use cases across the development cycle this will continue to be the case.  I suspect even with a perfect tool, it won't ever be perfect for everyone.
 

However, if there is a desire to focus resources on consolidated tooling and
someone to drive it forward, then I definitely agree that the effort needs to
start upstream with a singular plan for tripleo-ci. From what I gather, that
would be some sort of alignment and reuse of tripleo-quickstart, and then we
could build from there.

+1
 

That could start as a discussion and plan within that community with some
agreed on concensus around that plan. There was an initial thread on
openstack-dev related to this topic but it is stalled a bit. It could be
continually driven to resolution via specs, the tripleo meeting, email or irc
discussion until a plan is formed.

+1,  I think the first step is to complete the original blueprint and move on from there.
I think there has also been interest in having an in person meeting at summit.

Thanks!
