tridentbrtknr: With the latest patch set v1.14.8 deploys fine with calico plugin. With v1.15.5 I still get a bunch of pending pods. But that's perhaps expected?10:05
brtknrtrident: cool, but 1.15.5 works with flannel?10:06
*** rcernin has quit IRC10:06
*** pcaruana has joined #openstack-containers10:08
tridentbrtknr: Yes.10:08
brtknrtrident: interesting10:09
brtknrit could be a missing backport10:09
brtknrit could be another missing backport10:09
brtknrbut I cant think of which one it could be10:11
brtknrAny reason why the pods are in pending?10:11
brtknrwhich pods are pending?10:11
openstackgerritDiogo Guerra proposed openstack/magnum master: Prometheus metrics from traefik  https://review.opendev.org/69704410:13
tridentbrtknr: Might be a error in my test env. One moment. I'll try respinning in a few minutes. It's a bit of a mess with all the patches on top of each other.10:13
brtknr:D10:13
brtknrtrident: you can simply do `git review -d 696916` to open a new branch with only the relevant patches :)10:14
tridentbrtknr: There, in a better state now. But the issue with 1.15.5 persists.10:27
tridentbrtknr: calico-kube-controllers, coredns, heapster, kube-dns-autoscaler, kubernetes-dashboard all hangs in Pending. Nodes are in state NotReady: "KubeletNotReady runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized"10:28
brtknris openstack cloud controller manager running?10:29
tridentbrtknr: Nope.10:29
brtknris there a daemonset for it?10:29
tridentbrtknr: How do I check that?10:30
brtknrkubectl get ds -A10:30
brtknrtrident:10:30
tridentbrtknr: kube-system   openstack-cloud-controller-manager   0         0         0       0            0           node-role.kubernetes.io/master=   32m10:31
brtknrok good so its there10:31
brtknrmind sharing the output of kubectl get all -A10:31
brtknris there anything in failing stating?10:32
brtknris there anything in failing state?10:32
brtknris the master node labelled as master?10:33
*** lpetrut has joined #openstack-containers10:34
tridentbrtknr: Nothing in failing state in kubectl get all -A - only Pending10:35
tridentbrtknr: master node has the label "node-role.kubernetes.io/master="10:36
brtknrhmm curious10:36
tridentIt does have a few taints though: "CriticalAddonsOnly=True:NoSchedule", "dedicated=master:NoSchedule", "node.cloudprovider.kubernetes.io/uninitialized=true:NoSchedule" and "node.kubernetes.io/not-ready:NoSchedule"10:37
brtknrtrident:  is there aynthing in Running state at all?10:37
brtknrany of the mopods10:38
brtknrany of the pods10:38
tridentbrtknr: calico-kube-controllers has Warning "FailedScheduling 56s (x29 over 41m)  default-scheduler  0/3 nodes are available: 3 node(s) had taints that the pod didn't tolerate."10:39
tridentAnd so does the other pods.10:40
brtknrtrident:  is there aynthing in Running state at all?10:40
tridentbrtknr: Doesn't seem like it...10:41
*** udesale has quit IRC10:44
brtknrtrident: I know what the issue is I think10:49
tridentbrtknr: Oh, cool!10:50
brtknrtrident: however, its an extremely messy backport10:53
brtknrits this patch you need: https://review.opendev.org/#/c/694032/410:54
brtknrso I think I'm not going to bother pursuing it10:54
*** udesale has joined #openstack-containers10:58
tridentbrtknr: I'll check to see how bad it is to apply it. Just need to get some lunch first. Will get back to you with the result!11:01
brtknrtrident: feel free to try, i dont think it will work personally11:02
brtknrtrident: without some more backports11:03
brtknras the way these pods are deployed has also changed11:04
brtknrthe way that calico/flannel services are deployed has changed, they run as containers whereas in rocky, i think they run as systemd service11:05
brtknrtrident: are you saying you dont have calico-node service running?11:10
brtknrtrident: this might work but no guarentees, I omitted the changes for flannel as that runs as systemd service in rocky11:21
brtknrand as you say, its working fine11:21

*** lpetrut has quit IRC11:53
tridentbrtknr: Beautiful! https://review.opendev.org/697060 seem to have done the trick!11:54
brtknrtrident: cool!11:55
openstackgerritBharat Kunwar proposed openstack/magnum stable/rocky: k8s_fedora_atomic: Add PodSecurityPolicy  https://review.opendev.org/69706011:59
tridentbrtknr: Then we just need a few +2:s and +W:s. Anything I can do to speed that up? Comments on any of the changes for example?12:14
brtknrtrident: that would help12:15
brtknrtomorrow is our weekly meeting12:15
tridentbrtknr: Again, thanks for working with us on this. It makes it so much easier not having to have locally applied patches...12:15
brtknrat 9AM UTC12:15
brtknryou can bring this up in the meeting and highlight its importance to you12:15
tridentbrtknr: Yeah, I intend to join it! Thanks!12:16
brtknrrocky release is fraught with other issues but helps to have the main deployment issues ironed out12:16
brtknrother issues are mainly related to outdated helm charts etc.12:17

dioguerrawe need the DaemonSet15:19
brtknrdoes the chart not deploy a daemonset?15:20
brtknrdioguerra: i was just thinking why we implement ingress in the current way where a node needs to be labelled to act as the ingress node15:22
