Community use cases meeting
by Fabiano Fidêncio 19 May '21

19 May '21

Yesterday, Apr 6th, during the Architecture Committee meeting, we discussed the possibility of having the community use cases meeting split, and I assigned myself the action item to create a doodle and send an email. Well, let me start saying that I may have failed in the doodle thing, but I still am dropping the email with what I heard as a feedback and what I would like to suggest. I got the feedback, from more than one person, that the time for the community use cases meeting is not exactly optimal for everyone, and that is right. For instance, it may be too early for folks in some parts of the US, while it is still too late for folks in Australia. With this in mind, I would like to ask whether there is the interest to split the meeting, allowing then the involved parts to talk to each other in a time that suits them best. So, this message is for everyone, but here I am explicitly looking for feedback from folks interested in: * K8S CI/CD pipeline with kata containers - Here we have people interested from the US and Australia, so maybe a late meeting in the US time zone would benefit the folks in Australia. * Performance isolation - Here we have people interested from the US and China, so maybe a late meeting in the US time zone would benefit the folks in China. If the parts involved in this have the interest to do so, let me know and then I will try to organise a doodle, set an official time, etc, etc, etc. We, as the community facilitating this communication, are here to facilitate the communication in a way that it will be beneficial for all the involved parts. Best Regards, -- Fabiano Fidêncio

Migration to Kata 2.0, and support timeline for 1.x
by Eric Ernst 11 May '21

11 May '21

Hey kata folk -- With 2.0 out now, we are focusing continued development and improvements on the 2.0 code base. As a result, in a prior architecture committee meeting discussion, we made the decision on a 6 month window (from release of 1.12) before stopping regular support of the 1.x (1.11 and 1.12 currently) branches. Based on this, here's a first heads up! We plan to deprecate support for 1.x on May 12th 2021. Thanks! Eric

RFC: direct-assigned filesystem volume proposal
by Eric Ernst 28 Apr '21

28 Apr '21

Ya'll, I'd like to see if we can create a pattern in upstream Kata Containers to help facilitate directly assigning volumes to the VM via virtio-blk, skipping any mounts on the host, and avoiding needing to use a shared file-system for the particular volume. Some of the benefits in doing this: - we can better isolate the host (no mounted filesystem), - more efficient and much faster data path that non-dax virtiofs. - avoid inode caching/memory overheads of virtiofs on the host. In Kubernetes today, there is not a direct communication channel between CSI and the runtime. To make this work on a shorter timeline, therefore, we need to come up with a less traditional way to communicate between the user, CSI and the runtime. I have a proposal in place that "works" today, and I'd like to get feedback on how to improve it, and see if it could be a good fit for upstream. Please see: the proposal at [1], and the PR associated with that proposal at [2]. Please let me know if you: - have any suggestions on the pattern - you are a user that would find this pattern helpful for their use-cases Thanks, Eric [1] - https://github.com/egernst/kata-containers/blob/da-proposal/docs/design/dir… [2] - https://github.com/kata-containers/kata-containers/pull/1568
