Up for a challenge? Unit testing y'all!
by Hunt, James O 11 Aug '20

11 Aug '20

Hi All, - Want to learn more about the internals of Kata but don't know where to start? - Are you keen to contribute to Kata? - Can you code in golang or rust? If you answer yes to those questions, read on...! ;) # Summary We're looking to increase the unit test coverage for the development versions of the Kata 2.0 [1]. Specifically, we want to increase coverage levels for the following Kata 2.0 components: - runtime (written in golang) [2] - the new agent (written in rust) [3] The unit test coverage levels have slipped for the runtime and the new agent is so new it still lacks tests in certain areas. This is an important activity as you have the chance to find (and potentially fix!) bugs before they are unleashed into the wild. # Details There is a top-level issue for each component (runtime [4], agent [5]). Each of those top-level issues has a number of related issues that breaks the work down into smaller chunks (there is an issue per directory/module, or even per file in some cases). # Tracking I've added all those task issues into the Kata 2.0 GitHub project [6]. # Get involved If you'd like to be involved, please let us know by adding a comment to [4] or [5] and we can help you find an interesting area to work on with us. Conversely, please don't start writing tests without telling us to avoid disappointment when we discover multiple people are writing the same set of tests! # Advice You should definitely read [7] first and you may find [8] and [9] helpful (the latter for golang tests). Before writing any new tests, please look at the existing tests for inspiration. Note also that some tests must run as root, whereas others must run as a non-privileged user. It's important to always consider which users your tests should run as (and we have infrastructure to ensure the tests DTRT). # Team effort If you want to volunteer to write some tests for a particular area and are happy to do that on your own, great! However, please don't think this is expected - if you volunteer, we're more than happy to help you out - remember that GitHub issues can be assigned to multiple users :-) Cheers, James [1] - Although we're focussing on 2.0, these new tests will also be backported where possible.

Transfer ARM CI maintenance
by Penny Zheng 30 Jul '20

30 Jul '20

Hey Kata ~colleagues~ :-) I’m Penny Zheng from ARM. Since we’ve been working happily together in the Kata community for more than two years, I’m deeply sorry to say that I’m not gonna be responsible for maintaining ARM CI on kata containers. 😭😢😡 It has been transferred to my wonderful colleague: @Jianyong Wu<mailto:Jianyong.Wu@arm.com> internally. And I may need to also transfer my Jenkins authority to him too. 😊 need help on this. Working upstream with you guys has been sooooooooooooo great, and thanks a thousand times for the help and tuition all along the way. 😘😘😘 And this is not a good-bye, and I will still try my best to contribute to Kata🤯😉. But when asking me for comments, my answers will likely be not as fast as they (hopefully) were. Thanks Penny IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

October/November PTG Date Selection
by Kendall Waters 27 Jul '20

27 Jul '20

Hello Everyone! We wanted to get your input on the best dates for holding the PTG now that its been annouced that the Summit itself will be virtual[1]. Please fill out the CIVS poll by August 3 at 15:00 UTC. We really appreicate your feedback! Poll: https://civs.cs.cornell.edu/cgi-bin/vote.pl?id=E_a69944444a9b7c93&akey=3ecc… <https://civs.cs.cornell.edu/cgi-bin/vote.pl?id=E_a69944444a9b7c93&akey=3ecc…> There are obviously many pros and cons to each option, below are the conflicts/reasons why we might not want to select that option. Option 0 - Two weeks before Summit (October 5-9) Conflicts with RC work External Event Conflicts: None? Option 1 - One week after Summit (October 26-30) Halloween on Oct 31 Perfect for release timing but event fatigue is a real concern External Event Conflicts: Open Source Summit EU, ODSC Open Data Science Conference East Cloud Foundry Summit EU, KVM Forum Option 2 - Two weeks after the Summit (November 2-6) USA Election day on Nov 3; could be a distraction, contributors needing to go vote (whatever that looks like with the virus), news, etc. Event Conflicts: None? Option 3 - Three weeks after the Summit (November 9-13) Pushes far into the cycle (4 weeks after previous release, a bit late, Veterns day/holiday - may affect France and Germany and US) External Events Conflicts: VMWorld EU -The Kendalls (diablo_rojo & wendallkaters) [1] http://lists.openstack.org/pipermail/openstack-discuss/2020-July/016068.html <http://lists.openstack.org/pipermail/openstack-discuss/2020-July/016068.html>

Kata containers backlog review meeting - doodle poll
by Ariel Adam 26 Jul '20

26 Jul '20

Hi everyone. Following today's weekly kata call we agreed to set up a meeting to review and clean the kata open issues backlog ( https://github.com/kata-containers/kata-containers/issues?q=is%3Aopen+is%3A… ). The idea is then to add additional labels to the cleaned backlog for identifying the high priority ones being actively worked on and track them closer. We can then help focus on completing those issues and unblocking them if needed. Following is a doodle poll with 5 proposed time slots for next week: https://doodle.com/poll/736ba6qq4ezex8ak The time slots are around the weekly call time so it isn't too late for the US or too early for China :-). Thanks.

WIP/SoB checks
by Thierry Carrez 24 Jul '20

24 Jul '20

Hi everyone, The SoB/WIP checks are currently broken (since last Zuul restart last Friday), I'm waiting for the US to wake up to dive deeper into the cause and fix it... but I was wondering if we should not consider dropping the Zuul tenant, and just use some other GitHub integration instead. When PullApprove decided to change its ToS in 2019, we decided to reimplement the WIP and SoB checks using Zuul. The idea was to use it as a way for kata to experiment with Zuul and potentially move more of its testing in that direction. 18 months later, efforts to move more Kata testing toward Zuul seems to have been abandoned. Having a full Zuul tenant just to run things as basic as a WIP and SoB check is clearly overkill, and adds complexity / technical debt to the CI chain. Probot is open source and has DCO and WIP checks available. The main difference is that it only supports the word "WIP" (or "wip") being set in the PR title, and does not watch custom labels.... so you could no longer use a "do-not-merge" label for example. But otherwise we could migrate to it very quickly... Thoughts? Do you plan to use more Zuul jobs in the future, and maintaining a Kata tenant there makes sense ? Or should we just simplify the setup ? -- Thierry Carrez (ttx)
