OpenStack PTG Denver – Day 5

Day 5 of PTG started as day for hackathons, general project/cross-project discussion for most project teams with many people left from PTG and few preparing for their travel plans or site-seeing in Colarado. The kolla team started the day with alternate Dockerfile build tool review. Later in the day was something everything in OpenStack and containers community was looking forward to the OpenStack – Kubernets SIG with Chris Hodge leading the effort to get everyone interested in same room. Some key targets for the release were identified including contributors interested. We then had most pressing issue for all deployment projects based on containers, the build and publishing pipeline for kolla images with openstack-infra team. Most of the current requirements, needs and blocking points were identified for rolling this feature. The kolla team and openstack infra team will work together to get this rolling in the starting phase of this cycle once zuul v3 rollout stabelizes. The kolla team ended day early for some much needed buzz for the whole week’s work at Station 26.


This is all from this edition of PTG see you next at Dublin.

OpenStack Queens PTG – Day 4

Day 4 of PTG started with next Kolla discussions related to kolla-ansible. Discussion started with kolla dev-mode effort started by pbourke. discussion was about currently missing pieces in dev_mode like installing clients, libs and virtualenv bindmount. The goal in the cycle is to fill the missing pieces, verify options for multinode dev_mode, investigate on options for remote debugging and also consider using PyCharm.

One of the important topics in kolla is the gating. Currently kolla has around 14 different gates for deployment testing and it has to be improved with testing the deployment for sanity with Tempest. This will help the validate the entire deployment in the gates. Upgrades testing is also one key requirement, kolla team will model something like grenade testing for it. The key is to maximize the testing of scenarios that kolla supports in gate, but since we are restricted with openstack infra resources as well as the time each test takes to validate. It is agreed that team members will create a list of scenarios and assign to everyone to verify and record the results in a central location like a google sheet. This will also help evaluate stability of kolla deployment in each release.

Skip level upgrades is one of the major talking point in the current PTG. Kolla team will evaluate fast forward upgrades for each service deployed with kolla to decide on skip level upgrade support in kolla. This would be a PoC in current cycle.

Second half of the discussion was around the kolla-kubernetes, where the team discussed the roadmap for current cycle. That will include upgrade prototyping for z stream & x stream services, validate the logging solution with fluent-bit, automated deployment, remove deprecated components and improve documentation.

Most of the teams have wrapped up their design discussions on Thursday and will be having hackathons on the last day.

OpenStack Queens PTG – Day 3

Day 3 of Queens PTG started with project specific design discussions, I joined the Kolla team where we started with the topic first for all the design summits we have had and very much important for the community, the “Documentation“. We broke down the discussion in documentation for quick-start with kolla, contributor, operators and reference documentation. The documentation available currently is scattered across projects after project split and its essential that it has a common landing page on OpenStack Deployment guides where everyone can refer to. We had representatives from the Documentation team Alex, Doug and Petr who are working on improving the doc experience by migrating the docs to a common format across the community. They understood the problem kolla is facing and we had a working discussion where we created the table of contents for all available and required documentation required for kolla.

Kolla team then joined the TripleO team which is consuming the kolla images for OpenStack deployment for discussion about collaboration of effort. The teams will work together to improve the build and publish pipeline for kolla images, improving & adding more CI jobs for the kolla/kolla-ansible/kolla-kubernetes, Configuration management post deployment of containers. The tripleo team has come up with basic healthchecks for containerized deployment, the kolla team will help get those checks in current kolla images and improve on those to better monitor the contaierized OpenStack deployment. The teams will also collaborate on improving the orchestration steps, container testing, upgrades and creating metrics for OpenStack deployment.

During lunch we had extended the discussion with Lars and kfox for discussion around Monitoring for OpenStack, Prometheus and other monitoring tools.

Post lunch, kolla team started with key discussion to the heart of operators, the OpenStack plugins deployment with kolla. There are multiple issues currently related to plugin as when would be ideal time to make them available, during build/deployment? Plugins might have non-matching depedencies to OpenStack components and so further. The team came up with multiple permutation of options available which would need to be PoCed during the release.

Since the inception of project loci there has been discussion around kolla-images size and the team had an interesting discussion on how to reduce that. The important part is to remove the things like apt/yum cache, removing the fat base image and so further. The team also discussed about utilizing althernate container build tooling to writing own image build tool. The team will hack on Friday removing the fat base images and see if that improves the image size.

External tools like Ceph are common pain points when we are doing OpenStack deployment. When kolla community evaluated the options for Ceph as storage backed for containerized openstack deployment there was no thing like containerized ceph. The team build it from scratch and got it working. The ceph team has currently come up with ceph-docker and ceph-ansible. It would be useful for operators that kolla uses the tools directly available from vendors for. We had a discussion with representative from ceph to initiate the collaboration to deprecate current ceph deployment in kolla and use the combination of ceph-docker & ceph-ansible. It will help both the communities will benefit exchange things done better at each end.

I got a surprise gift of vintage OpenStack swag from the PTG team

and I had another photo with the marketing team for with the TSP members.

The day ended with hanging out with kolla team mates at Famous Dave‘s

OpenStack Queens PTG, Denver – Day 2

Sep 12, 2017

The day started with meeting with people at registration desk hallway. I joined the TC discussion around Q & A for new projects in OpenStack. The discussion included emerging projects like Blazar, Glare, Gluon, Masakari, Stackube, Cyborg and Mogan. Each project representative presented TC members with general project overview, objectives, current status and any queries related to the Requirements for new OpenStack Projects applications. TC members also asked details related to maturity of projects w.r.t. contributors diversity, potential to increase collaboration, identifying any overlap with current/existing projects in OpenStack. We also had a discussion around potential project removals from OpenStack official projects. This is due to very low contributor activity during the cycle, no project goals achieved or changed focus of the participating organisations. THe particular projects highlighted in the area are Searchlight, Solum, Designate, CloudKitty.

I and inc0 were chasing the infra/TC members for resolution related to publishing kolla images on public registry like with openstack-kolla namespace. We did not get any direct resolution, need to initiate a discussion on openstack-dev mailing list for further discussion.

I met with Saad Zaher PTL of Freezer regarding the current status of project. I had very informative discussion and got my path clear for things to do ahead.

We had few hallway discussions related to kolla-kubernetes, openstack-helm, kolla with Ironic, kolla with neutron.

In the mean time we also had team photos clicked for kolla and requirements team. Looking forward to get them from the OpenStack marketing team.

This now ends the fist section of schedule of inter-project discussions. The day ended with IBM sponsored happy hour in the hotel where random discussions happened regarding projects, OpenStack, etc.

OpenStack Queens PTG, Denver – Day 1

It is my first time joining the Project Teams Gathering since it started in Atlanta. The location of the event is pretty unique its own way. I had never been to this part of USA and you can feel the difference. The event is held in the Renaissance Denver for 5 days between Sep 11-Sep 15.

I arrived here on Sep 10 and I could already see the active contributors in the hotel lobby discussing something or the other. I met some of the friends and took rest on the day further.

Sep, 11, the day started with registration for the event. I joined the #openstack-ptg channel to get the updates about the day and there I got introduced to ptgbot. Initially many people including me were a bit confused with how it works, but as we got familiar with it, we got more used to it for tracking the events.

As per schedule, the first two days of the event are dedicated to inter-project discussions.

I headed directly to the infra/stable/release/requirements room for discussions of requirements team. We had a discussion around topics to be worked on in Queens which include the per-project/independent/divergent requirements, OpenStack client testing, Python 3. The discussion was pretty good with insights provided by tonyb, promentheanfire, dirk, mordred, notmyname

Post lunch I joined Kolla team with discussions around collaboration across different deployment tooling in OpenStack. We had discussions around architecture, health monitoring, the role of containers, kubernetes and security.

I also attended the TC meeting for Rebooting of the Stewardship WG and Onboarding new community members.

The day ended with unofficial PTG happy hour at the elevated lounge in Renaissance Denver.
