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.
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
