I wanted to make sure we got a summary of this meeting sent out. Notes were kept at https://etherpad.openstack.org/p/Wqxwce1UDq

Airship needs to test their All in One deployment tool. This tool deploys their entire bootstrapping system into a single VM which is then used to deploy other software which may be clustered. Because the production usage of this tool is via a VM it is actually important to be able to test the contents of that VM in CI and that is what creates the memory requirements for Airship CI.

We explained the benefits of being able to run Airship CI on less special hardware. Airship gains redundancy as more than one provider can supply these resources, reliability should be improved as nested virt has been known to be flaky, and better familiarity within the community with global resources means that debugging and working together is easier.

However, we recognize that Airship has specific constraints today that require more specialized testing. The proposed plan is to move forward with adding a new cloud, but have it provide specialized and generic resources. The intent is to address Airship's needs of today with the expectation that they will work towards running on the generic resources. Having generic resources ensures that the infra team has exposure to this new cloud outside the context of Airship. This improves familiarity and debuggability of the system. It is also more equitable as other donations are globally used. Also, Nodepool doesn't actually allow us to prevent consumption of resources exposed to the system; however, we would ask that specialized resources only be used when necessary to test specific cases as with Airship. This is similar to our existing high memory, multi numa node, nested virt enabled test flavors.

For next steps we'll work to add the new cloud with the two sets of flavors, and Airship will begin investigating what a modified test setup looks like to run on our generic resources. We'll see where that takes us.

Let me know if this summary needs editing or updating.

Finally, we'll be meeting again Wednesday January 29, 2020 at 1600UTC to followup on any questions now that things should be moving. I recently used jitsi meet and it worked really well so want to give that a try for this. Lets meet at https://meet.jit.si/AirshipCICloudFun. Fungi says you can click the circled "i" icon at that url to get dial in info if necessary.

If for some reason jitsi doesn't work we'll fall back to the method used last time: https://wiki.openstack.org/wiki/Infrastructure/Conferencing room 6001.

See you there,
Clark
