| xzr | ahh actually got Kata running on Atomic now | 12:11 |
|---|---|---|
| xzr | took a bit of tinkering and disabling :| | 12:11 |
| xzr | had to remove --selinux-enabled from docker cmd line and --exec-opt native.cgroupdriver=systemd from docker.service | 12:13 |
| *** gwhaley has joined #kata-general | 12:14 | |
| xzr | not sure what the cgroupdriver thing does, but apparently kata-runtime doesn't support it | 12:14 |
| * gwhaley joins, see's xzr comment - doesn't know if there was more before that ... so...... | 12:18 | |
| gwhaley | hi xzr - do you have some context for that - is that a docker or k8s or kernel thing for instance? | 12:18 |
| gwhaley | Maybe open a github issue on kata-containers/runtime to get more feedback - others might know more | 12:18 |
| xzr | gwhaley: I'll paste | 12:20 |
| xzr | sorry for the spam for the rest | 12:20 |

| xzr | docker.service | 12:21 |
| xzr | I guess if you fellows are interested in the setup instructions I'd be happy to share | 12:21 |
| xzr | also welcoming any ideas for re-enabling selinux :p, it was complaining about missing labels | 12:23 |
| xzr | I reckon the default selinux rules used for containers don't play well with kata | 12:32 |
| xzr | https://www.projectatomic.io/blog/2016/07/docker-selinux-flag/ | 12:32 |
| gwhaley | that's great news @xzr - nice :-) Would be great if we can get a doc together like we have for OpenStack Zun for instance: https://github.com/kata-containers/documentation/blob/master/zun/zun_kata.md | 12:38 |
| gwhaley | cgroupdriver is explained a bit on here: https://docs.docker.com/engine/reference/commandline/dockerd/#options-per-storage-driver | 12:40 |
| xzr | haven't ran anything proper yet, but atleast uname -a reports a different kernel than on the host :) | 12:40 |
| gwhaley | What I think that means for kata is that, if we were to support it, we would have to add the ability to the agent to use systemd for cgroup control and not cgroupfs - which, I think should be technically possible as the agent uses the same library for this stuff as docker runtime does... | 12:41 |
| gwhaley | xzr: just to get that uname report means quite a lot is working :-) | 12:41 |
| gwhaley | xzr: let me open a couple of github issues for Atomic and cgroupdriver, and cc you on them - if OK with you then, what is your github handle? | 12:42 |
| xzr | the same | 12:42 |
| gwhaley | ;-) | 12:42 |
| xzr | I can post the setup steps there for discussion | 12:42 |
| gwhaley | yep - let me make the Issue, and we'll get some info up there. thx! | 12:43 |
| xzr | np and thanks! | 12:43 |
