@rager:synapse.lickmy.apprageroh shoot... so it's a thing - cgroups v2 unified format is mucking up all us container users?17:05:49
@rager:synapse.lickmy.appragerI'm running into lots of "failed to run Kubelet: mountpoint for cpu not found" when I run the nixos kubernetes packages in a nixos container17:07:40
@colemickens:matrix.orgcolemickenswell that probably has to do with trying to run a container manager inside a container17:43:29
@colemickens:matrix.orgcolemickenssomehow I didn't realize a patch was needed for this: https://www.phoronix.com/scan.php?page=news_item&px=Linux-Boot-Non-BD-File-Systems&utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+Phoronix+%28Phoronix%2917:43:50
@colemickens:matrix.orgcolemickenswhich would be useful in my virtiofs + kata for Nix scenario17:44:03
@andi:kack.itandi-Does virtiofsd still require a daemon running as root?17:53:31
@colemickens:matrix.orgcolemickensyes. " The program drops privileges where possible during startup although it must be able to create and access files with any uid/gid:"18:06:47

If you want to support multiple uids this would be needed. But in theory usernamespaces could help with that.
18:31:50
@joerg:bethselamin.deMic92 (Old)I can check with my Kata containers18:32:18
@andi:kack.itandi-I wanted to use it for the NixOS VM test a year ago when it was merged into the kernel but that daemon requirement was a show stopper :/18:32:50

K8s has an option to fix that

It should not be impossible support. Upstream probably would accept PRs for that. I put this on my to-do list. I know fuse quite a bit

@arianvp:matrix.orgArianI have a Kubernetes module in my personal repo that uses cri-o and puts Kubelet in systemd Cgroup mode. It works fine with cgroups v218:35:43
@arianvp:matrix.orgArianBut yeh by default Kubernetes still defaults to cgroupfs and docker and that will definitely not work18:35:59
@arianvp:matrix.orgArianThe docker driver is practically deprecated so idk if it will ever support it. We should perhaps move the default CRI driver in nixos to cri-o18:36:39
@arianvp:matrix.orgArianI don't have enough time to turn this into a proper PR atm18:37:14
@colemickens:matrix.orgcolemickensAre there any k8s installs in the wild that default to cri-o that aren't administered by RH/IBM?18:54:22

@colemickens:matrix.orgcolemickensOracle Cloud is quite the peach. I'm logged into my Oracle account and was logged into my Oracle Cloud account yesterday, today, it just seems to be bugged, as if their SSO is down or some such.21:13:25
@colemickens:matrix.orgcolemickens btw Mic92 if you put anything special in your kexec payload for your ARM oracle cloud instance, I'd love to see it 21:14:06
