flwang1strigazi: around?09:03
flwang1strigazi: seems we're have a new issue with the heat-container-agent09:03
flwang1it's reporting a locale issue now09:03
brtknrflwang1: thats the same issue as what i had... had to change heat_container_agent_tag=stein-stable09:17
flwang1brtknr: i had put some time on that, but haven't figured out the root cause yet09:17
brtknrflwang1: https://storyboard.openstack.org/#!/story/200638209:17
brtknri repored the issue on storyboard on 8 august09:18
flwang1brtknr: thanks09:19
brtknrflwang1: even tried changing the locale of the devstack machine but no help09:19
flwang1brtknr: i will continue to debug, will update status on that story09:20
brtknr09:20
brtknrhow do you approach debugging heat-container-agent container?09:21
brtknrflwang1: ^09:21
brtknrflwang1: also could you please take a look at this urgently: https://review.opendev.org/#/c/675548/09:22
brtknrthe controller manager fails to deploy without this09:23
flwang1brtknr: i'm going to enable more log for the launch script, and if that doesn't work, i will probably build a personal os-collect-config lib to debug09:23
flwang1it's a big tricky, because the container can't start at this moment09:23
flwang1a simpler way we can try is, don't run the os-collect-config script when start the container, then after start the container, login the bash of the container to run the command manually09:25
flwang1and add pdb for the os-collect-config to get more information09:25
flwang1without heat-container-agent, anything can't work09:25

brtknrgoldyfruit_: btw have you seen this before: Aug 12 11:57:08 testk8s-zpmpusaolfdn-master-0.novalocal runc[3610]: error: SchemaError(io.k8s.api.apps.v1beta1.ControllerRevisionList): invalid object doesn't have additional properties14:03
brtknrthis is when creating openstack-cloud-controller-manager pod in the kube-system namespace14:03
brtknrthis is via the heat-container-agent14:03
brtknrif i apply the template manually, no complaints14:04
brtknrmy suspicion is that the control plane is still getting ready14:04

brtknrgoldyfruit_: i am trying to find out how the latest version of kubectl gets installed14:47
brtknrany idea?14:47
brtknri cannot find the part of the softwarewaredeployment script that is responsible14:47
brtknrthis is on the master node14:47
brtknrcould it be one of the kube_* services' overlayfs?14:48
goldyfruit_brtknr, https://github.com/openstack/magnum/blob/a70341e278a7592ef880076445d3f2a106ed6a23/dockerfiles/kubernetes-apiserver/Dockerfile14:48
goldyfruit_It's part of kube-apiserver Docker image14:49
brtknrgoldyfruit_: it looks like the reason I am hitting the issue I reported earlier is because, at the point that heat-container-agent gets fired, there is mismatch between the version of kubectl on the client and the server14:51
brtknrbrtknr, https://github.com/openstack/magnum/blob/a70341e278a7592ef880076445d3f2a106ed6a23/dockerfiles/kub14:51
brtknrernetes-apiserver/Dockerfile14:51
brtknrWriting File: /srv/magnum/kubernetes/openstack-cloud-controller-manager.yaml14:51
brtknrClient Version: version.Info{Major:"1", Minor:"10", GitVersion:"v1.10.3", GitCommit:"2bba0127d85d5a46ab4b778548b14:51
brtknrServer Version: version.Info{Major:"1", Minor:"14", GitVersion:"v1.14.5", GitCommit:"0e9fcb426b100a2aea5ed5c25b314:51
brtknras so^14:51
brtknrgoldyfruit_: I found the problem!14:54
goldyfruit_brtknr, Yeah!14:55
brtknrBecause the script is running from heat-container-agent, it is using the kubectl client from the container14:55
brtknrheat-container-agent has the old kubectl client14:55
brtknrhttps://github.com/openstack/magnum/blob/master/dockerfiles/heat-container-agent/Dockerfile#L1814:56
goldyfruit_brtknr, but you are using rawhide tag which is from February14:57
goldyfruit_So I guess this is normal to have an old client in there14:57
*** ykarel|afk is now known as ykarel|away14:57
goldyfruit_If you want a newer client you will have to change your heat-container-agent tag14:57
goldyfruit_but last time you tried stein-stable/train-dev you had troubles14:58
brtknrgoldyfruit_: my heat_container_agent_tag is rocky-stable as I am using openstack rocky15:01
brtknrits not just an old client, its a really old client15:01
goldyfruit_brtknr, rocky works until 1.11 I think15:02

*** ykarel|away has joined #openstack-containers15:04
brtknrgoldyfruit_: ah i see15:05
brtknrgoldyfruit_: i think it can work for other versions if we change heat_container_agent_tag to stein-stable15:07
goldyfruit_brtknr, yes it could15:08
*** dave-mccowan has joined #openstack-containers15:21
brtknrgoldyfruit_: looks like the heat_container_agent_tag doesnt get respected in rocky :(15:52
