| dinechin | Hi. total newbie here. What is the recommended way to run some diagnostics for a running kata container, e.g. similar to `docker exec -i -t my-container /bin/bash`? | 09:38 |
| kata-irc-bot | <xu> @graham.whaley I think I could be online | 09:42 |
| kata-irc-bot | <xu> I am in the convention center for KubeCon/Open Source Summit Shanghai :slightly_smiling_face: | 09:44 |
| kata-irc-bot | <xu> And bergwolf is here as well, but I don't know which room he is in | 09:44 |
| kata-irc-bot | <graham.whaley> ah, np @xu - quick question - do we have any specific documentation, Issues or *code* in Kata about High Availability? | 09:46 |
| kata-irc-bot | <graham.whaley> I think you guys have probably thought about that the most... | 09:47 |
| kata-irc-bot | <xu> I don't think we have doc on it. But we are considering live-upgrade of the kata components in recent weeks, and I think we should create an issue on it. I think @weizhang555’s persistence work could be part of it. | 09:49 |
| kata-irc-bot | <weizhang555> > I think @weizhang555’s persistence work could be part of it. I agree. | 09:51 |
| kata-irc-bot | <graham.whaley> ah, live upgrade, thx, had not thought of that bit. Other bit I can think of is if agent can restart if running under a systemd rootfs. But, I guess the workload is the child of the agent?, so if the agent dies then the workload probably dies as well. So most HA stuff I imagine comes from the orchestrator ultimately. Also, now we tend to not have a proxy as we have vsock, the proxy does not come into HA any more either \o/ | 09:51 |
| kata-irc-bot | <graham.whaley> @dinechin - kata-runtime sits next to the normal 'runc' runtime. If you have it configured as your default runtime in docker, then the command you showed would run a kata container by default. If kata is not the default runtime, then adding the `--runtime kata-runtime` to the command should run a kata for you. `docker info` will tell you which runtimes are installed/configured in your `docker`. | 09:53 |
| dinechin | Thanks. Will try that. Thought it was "too simple" ;-) | 09:55 |
| kata-irc-bot | <weizhang555> If people are using containerd-shim-v2, I think the scene could be much simpler. You can safely upgrade kata-components, and new started container will be using new kata components... | 09:55 |
| kata-irc-bot | <graham.whaley> @dinechin - heh, if it's not simple, then we have probably failed ;) Yeah, it should be a pretty simple 'drop in replacement', and look and feel just like a container... | 09:56 |
| kata-irc-bot | <xu> I think the HA in kata may include the shimv2 and agent upgrade, and kernel live patching without interrupting the user workload. | 09:57 |
| kata-irc-bot | <weizhang555> That sounds great, but requires lots of work :bananadance: | 09:58 |
| kata-irc-bot | <graham.whaley> thanks @xu @weizhang555 - that has given me things to think about (trying to list what we have and where the gaps/plans are etc.). | 10:01 |
| kata-irc-bot | <graham.whaley> so, have an excellent conference! | 10:01 |
| kata-irc-bot | <graham.whaley> must be nearly time for beer there? ;) :beer: | 10:02 |
| kata-irc-bot | <weizhang555> @graham.whaley One issue for reference: https://github.com/kata-containers/runtime/issues/492 ;) | 10:03 |
| kata-irc-bot | <graham.whaley> oh, excellent :clap: | 10:03 |
| kata-irc-bot | <xu> The exhibition hall reception will begin in 50 minutes | 10:04 |

| kata-irc-bot | <eric.ernst> @manohar.r.castelino ^ curious for your thoughts here. | 18:15 |

| kata-irc-bot | <graham.whaley> hi fuentess - I hit an error trying to run `setup.sh` under my jenkins magic pipeline - it does not give a lot of clues :( per chance, have you seen this before when trying to install/setup the CNI stuff: ```var/spool/ var/spool/mail/ var/www/ ~/workspace/Graham-test-pipeline/go/src/github.com/grahamwhaley/kata-containers-runtime Move to /tmp/tmp.QXQfLsdlFc/virtcontainers/build /tmp/tmp.QXQfLsdlFc/virtcontainers/build | 19:28 |
| kata-irc-bot | ~/workspace/Graham-test-pipeline/go/src/github.com/grahamwhaley/kata-containers-runtime Clone cni Copy CNI config files /tmp/tmp.QXQfLsdlFc/virtcontainers/build/plugins /tmp/tmp.QXQfLsdlFc/virtcontainers/build ~/workspace/Graham-test-pipeline/go/src/github.com/grahamwhaley/kata-containers-runtime ``` | 19:28 |
| kata-irc-bot | <salvador.fuentes> @graham.whaley hmmm, not really, is that where the job stopped? | 19:29 |
| kata-irc-bot | <graham.whaley> ah, hold on, maybe I know..... | 19:29 |
| kata-irc-bot | <graham.whaley> because my 'runtime repo' is not in is 'natural path' - it is under my name. and golang don't like that, or not for vc/runtime repo anyhow.... | 19:30 |
| kata-irc-bot | <graham.whaley> and, yep, that is where the job stopped! :( | 19:30 |
| kata-irc-bot | <graham.whaley> Right, I can rework this in the morning! Probably pick a repo that is *not* the runtime ;) | 19:31 |
| kata-irc-bot | <salvador.fuentes> ok, at least you know what happened, but yeah, seem that it is very hard to debug this way | 19:31 |
