Hi Lee, I reviewed all I could in this list. It's impressive work! Thanks a lot. I'll keep an eye on it and try to help. Thanks, On Wed, Jan 16, 2019 at 5:58 PM Lee Yarwood <lyarwood@redhat.com> wrote:

Hello,

This is a brief status progress report on my work to enable the deployment of the extracted Placement service within TripleO ahead of the extraction check-in call later today.

tl;dr TripleO isn't ready to switch to an extracted Placement service or for code to be removed from openstack/nova.

# RDO (packaging)

https://review.rdoproject.org/#/q/topic:placement-add

This was started at the PTG in Denver and mostly completed some time ago now. I do however have a single change outstanding that includes the puppet-placement package as a dependency of puppet-tripleo but aside from that this is complete:

puppet-tripleo: Require puppet-placement https://review.rdoproject.org/r/18330

FWIW in the context of the extraction check-in call, both RDO and TripleO are not ready to deal with the original placement code being deleted from the openstack/nova project at this point. This will continue to be the case until the following work is completed to enable deployments using the extracted project in TripleO.

# Kolla (containers)

https://review.openstack.org/#/q/topic:split-placement+OR+topic:upgrade-plac...

The initial Kolla change to produce a placement-api container landed some time ago after some small delays due to the Stein UCA not being used for the Ubuntu binary jobs:

Split placement-api from nova https://review.openstack.org/#/c/613589/

FWIW an additional change to copy across the DB migration script has also been posted and is pending a package promotion in RDO:

Copy placement database migration script https://review.openstack.org/#/c/626382/

The above change isn't required by TripleO, I just wanted to highlight that kolla-ansible are looking to use the script during upgrades.

Unfortunately due various issues with TripleO promotions the TripleO container for the placement-api was only uploaded yesterday after I manually built it:

https://hub.docker.com/r/tripleomaster/centos-binary-placement-api

# Puppet

https://review.openstack.org/#/q/topic:tripleo-placement-extraction

The initial and massive puppet-placement cookiecutter change has landed:

Initial cookiecutter run and import from puppet-nova https://review.openstack.org/#/c/604182/

This is currently only tested on CentOS7 by the following POI or puppet-openstack-integration change that has itself been stuck behind a raft of Ubuntu py3 and Stein UCA issues:

placement: Extract the service from Nova https://review.openstack.org/#/c/615568/

I'm attempting to unblock this by working my way through the following changes to support py3 and the Stein UCA within the Ubuntu jobs:

https://review.openstack.org/#/q/status:open+topic:ubuntu-py3

https://review.openstack.org/#/q/status:open+topic:inherit_pyvers

Help with these changes from any openstack-puppet Ubuntu users would obviously be appreciated here!

Finally I'm currently working on the following puppet-tripleo change that makes this all usable within TripleO itself:

WIP placement: Initial extraction of the Placement service from Nova https://review.openstack.org/#/c/624335/

# TripleO

https://review.openstack.org/#/q/topic:tripleo-placement-extraction

On the TripleO front I almost have undercloud deployment completing in a reproducer environment with various local hacks to workaround changes not being merged yet. The main tripleo-heat-template change can be found below:

WIP placement: Extract the service from Nova https://review.openstack.org/#/c/630644/

# TODO

Obviously there's still a lot to do here but to begin with I'll be focusing on the following tasks:

- Landing the puppet-openstack-integration and puppet-tripleo changes. - Moving the tripleo-heat-templates change out of WIP. - Posting draft upgrade_tasks in a new change using the db migration script.

Hopefully this is of some use to folks in the Placement and TripleO teams!
