| kata-irc-bot | <lingniao> Hi guys I want to use test cases to find the difference in IO performance between the size of DAX window setting and the size of host files. It is said that if the file size exceeds the window size, dax has to do a lot of remapping work, the performance will drop sharply, I want to see if it is true I tried to use fio, but it seems that the commands used are not good enough. I can’t see that Kata has done a lot of maintenance wor | 01:11 |
|---|---|---|
| kata-irc-bot | on dax windows, which results in a lot of performance degradation. How can I observe it? configuration.toml default_memory = 3072 virtio_fs_cache_size = 512 fio -filename=/usr/share/nginx/html/400MBfile --rw=randread --loops=10 --group_reporting --name=400MBfile fio -filename=/usr/share/nginx/html/5Gfile --rw=randread -bs=16k --group_reporting --name=5Gfile | 01:11 |
| kata-irc-bot | <fidencio> I saw you also open an issue about this, am I right? | 07:05 |
| kata-irc-bot | <lingniao> Yes, no one replied in the email, maybe I wrote it not in detail enough, so put it in slack and ask again, is this way not recommended? | 08:52 |
| kata-irc-bot | <fidencio> I'd say, give it time for people to reply. This week and the next week is holiday season in US, also part of Europe. | 08:53 |
| kata-irc-bot | <fidencio> Do you have a link for the issue or the email? | 08:53 |
| kata-irc-bot | <fidencio> http://lists.katacontainers.io/pipermail/kata-dev/2021-July/001994.html right? | 08:54 |
| kata-irc-bot | <lingniao> yes,that is | 08:54 |
| kata-irc-bot | <fidencio> I'll try to loop in some folks from Red Hat who are working on this. | 08:54 |
| kata-irc-bot | <fidencio> But I think some of them may be off for the next few days | 08:55 |
| kata-irc-bot | <lingniao> That’s great, thank you very much. It doesn’t matter if the time is a little longer | 08:56 |
| kata-irc-bot | <matthieu.sarter> Hello, I have a question about the process for submitting changes. I want to submit a fix to the containerd install from source, which is currently broken, and it affects both the kata-containers (version.yaml) and the tests repo (.ci/install_cri_containerd.sh). Should I open an issue in each repo or a single issue in one repo (tests ?) and reference it in both PR ? | 08:58 |
| kata-irc-bot | <fidencio> np! :slightly_smiling_face: I hope that helps! | 08:58 |
| kata-irc-bot | <fidencio> You'll have to open one issue in each repo. The script looking for the "Fixes: #", IIRC, checks for an issue in the specific repo, and fails otherwise. | 08:58 |
| kata-irc-bot | <fidencio> Please, cc me there once you open the PR and I'll take a look at this ASAP | 08:59 |
| kata-irc-bot | <matthieu.sarter> Okay, thanks. Is there a way to indicate that both issues are linked ? | 08:59 |
| kata-irc-bot | <fidencio> I mean, in order to have the one in the tests passing, it depends on an update in the one from the kata-containers repo, correct? | 09:00 |
| kata-irc-bot | <matthieu.sarter> Yes | 09:00 |
| kata-irc-bot | <fidencio> If so, when doing the pull-request, do a normal issue creation & pull-request for the one in the kata-containers repo | 09:00 |
| kata-irc-bot | <fidencio> And then for the one in the tests you do: • Create the issue normally • In the commit message of the PR, you add: `Depends-on: github.com/kata-containers/kata-containers#NNN` | 09:02 |
| kata-irc-bot | <fidencio> with NNN being the number of the PR on the kata-containers repo | 09:02 |
| kata-irc-bot | <matthieu.sarter> thanks ! | 09:02 |
| kata-irc-bot | <fidencio> This is one example: https://github.com/kata-containers/kata-containers/pull/2128/commits/f49e40a3d2eb8935670cdd5ed4055f0196825fc7 | 09:02 |
| kata-irc-bot | <fidencio> Anytime! | 09:02 |
| kata-irc-bot | <matthieu.sarter> Well indeed someone already fixed it, I had three days old sources... Sorry for your time, but I will keep the informations in case I need it sometime later. | 09:44 |
| kata-irc-bot | <fidencio> No problem at all, Matthieu! Glad to help and thanks for your time playing with the project! | 09:54 |
| kata-irc-bot | <fidencio> Folks, this summarises the work we've been doing inside Red Hat with Kata Containers for some time now: https://futurumresearch.com/research-notes/red-hat-launches-latest-version-of-flagship-kubernetes-product-openshift-4-8/ The part that mentions the project is: """ OpenShift sandboxed containers, based on the Kata Containers open source project, provide a more secure container runtime using lightweight virtual machines. Available | 15:26 |
| kata-irc-bot | as a technology preview, this adds capabilities for specific workloads that require extremely stringent application-level security. Sandboxed containers provide an additional layer of isolation ideal for highly sensitive tasks, such as privileged workloads or running untrusted code. Given the recent ransomware attacks focused on CI/CD pipelines this is a welcome announcement. """ Kudos to everyone who helped this happen, an be sure I'm not | 15:26 |
| kata-irc-bot | only talking about the Red Hatters involved, but also about the whole support we have been having from this amazing community! | 15:26 |
| kata-irc-bot | <steven> Out of interest Matthieu - was the problem you saw this: https://github.com/kata-containers/kata-containers/issues/2054 ? | 15:43 |
| kata-irc-bot | <eric.ernst> swweeeeeet | 15:48 |
| kata-irc-bot | <eric.ernst> Thanks for sharing dude, and congrats on the milestone | 15:48 |
| kata-irc-bot | <david_hay> Perhaps an extremely dumb question, but I'm using `kata-agent` to run a process via `Command::new()` and would dearly love this process to pick up a custom environment variable - `GNUPGHOME` Given that the agent is running as a `systemd` daemon, and that I'm poking the agent ( in test ) using `kata-agent-ctl` I am struggling to find the best way to set the env. var. within the pod sandbox within which the agent runs I've looked | 17:07 |
| kata-irc-bot | at `/root/.bashrc` - but of course this isn't Bash - and `/root/.profile` and system-wide `/etc/environment` and `/etc/profile` - but to no avail .... Any ideas ? | 17:07 |
