livelaceHello everybody, what does this error mean ?10:56
livelace2018-07-09 12:04:21.868 130 ERROR kuryr_kubernetes.cni.daemon.service [-] Timed out waiting for requested pod to appear in registry: Resource not ready:10:56
openstackgerritShachar Snapiri proposed openstack/kuryr-kubernetes master: Move tempest-octavia-centos-7 back to check  https://review.openstack.org/57959910:57
irenablivelace, resource not ready exception allows to retry internally11:02
livelaceirenab, I see a lot of such errors in daemonsets logs11:05
livelacePods stuck and cannot work11:06
irenablivelace, do you run containarized?11:06
livelaceirenab, What "registry" is it ?11:07
*** livelace1 has joined #openstack-kuryr11:08
livelace1irenab: Yes, daemonset - containers inside Openshift Origin11:08
livelace1"registry" - it's a registry inside k8s/origin ?11:10
irenablivelace, I think dulek is the best person to guide you at this issue11:10
livelace1dulek: Ping11:10
livelace1irenab: Thanks11:10
*** livelace has quit IRC11:13
duleklivelace1: Yeah, so basically kuryr-daemon watches K8s API for new pods appearing.11:14
duleklivelace1: Fact that the pod was not found may mean that connection to K8s API is broken or watcher died (see bug https://bugs.launchpad.net/kuryr-kubernetes/+bug/1776676).11:14
openstackLaunchpad bug 1776676 in kuryr-kubernetes "CNI goes useless if the watcher loses connectivity with the API for longer than the retry timeout" [Critical,In progress] - Assigned to Antoni Segura Puimedon (celebdor)11:14
livelace1dulek: ok, but pods stuck with error like "CNI daemon return error"11:15
livelace1dulek: I catch this error from time to time, but I cannot understand why11:15
duleklivelace1: Sure, because after some timeout kuryr-daemon returns that it couldn't found the pod, so kubelet may retry the request.11:15
livelace1dulek: one moment please, i'm reading the bug11:16
livelace1dulek: The fix is not included in lates Docker images of CNI daemon. I understand it correctly ?11:19
duleklivelace1: It's not, not even merged. :(11:19
duleklivelace1: Is it happening always on a single node?11:19
duleklivelace1: Can you check out if watcher haven't stopped there? It's a log message similar to "Watcher stopped".11:20
livelace1dulek: yes, cni and controller probes are in disabled state. the problem exists on all nodes.11:20
livelace1dulek: No, no records that contain 'grep -i stopped'11:22
duleklivelace1: You mean unhealthy state? So maybe they are disconnected from K8s API?11:22
livelace1dulek: I restart daemonsets by hand, that, I guess helps to avoid the problem11:23
duleklivelace1: You can also try one workaround - set this option to an hour, or something: https://github.com/openstack/kuryr-kubernetes/blob/e9fd1004ab9ef843b3d168b278c2775d1f01ab6c/kuryr_kubernetes/config.py#L153-L15511:24
openstackgerritDaniel Mellado proposed openstack/kuryr-kubernetes master: (WIP) Implement Network Policies Driver  https://review.openstack.org/58098211:26
livelace1dulek: Once again, for sure. If readiness probes are disabled for CNI daemon - the bug above happens, yes ?11:27
livelace1dulek: I mean those probes https://paste.fedoraproject.org/paste/~Ui30hWdk0DJY7QM-9r55A11:28
openstackgerritLuis Tomas Bolivar proposed openstack/kuryr-tempest-plugin master: Namespace isolation tempest coverage  https://review.openstack.org/58067811:28
duleklivelace1: Yes, with probes kuryr-daemon will get restarted eventually and will reconnect.11:29
duleklivelace1: The workaround I've provided extends the timeout of reconnecting to K8s API, so even without the probes kuryr-daemon will retry connection.11:30
livelace1dulek: I will try your WA and I will try to enable probes for controller and cni daemons11:30
livelace1dulek: Thanks for your help!11:30
duleklivelace1: No problem!11:30

dulekdmellado: Hey, I think I've figured out requirements issue.13:14
dulekdmellado: Looks like requirements-check job is running only on patches that change requirements.13:15
dulekdmellado: Both of patches failing on Flask version are doing that.13:15
dulekdmellado: I'll take a look after I reconnect my router. Did I ever said how much I hate cables?13:15

dulekdmellado, irenab: ^ This should fix the patches that have issues with check-requirements job failing.14:07
dmelladohey dulek14:07
dmelladolet me check, I didn't see your pings ;)14:07
dmelladolol, dulek what happened to your router?14:07
dulekdmellado: It gets restarted every 30-60 minutes.14:08
dulekAnd of course the only thing that the guy on the line could help me was how to reset the router.14:08
dulekEven though I pointed out connection timeouts in router's logs.14:08
dulekSo it's now my turn to get some fun with dealing with ISP. :D14:09
dmelladoLOL14:10
dmelladodulek: what would you do that? They'd just say14:10
dmelladodid you try to turn it off and on again? xD14:10
dmelladoat least the spanish ones xD14:10
dulekdmellado: Nah, full settings reset. The guy might suspected I've played with channel ranges or other stuff. Still he could just asked.14:11
dulekdmellado: I guess it's because most of the people calling are: #1 Rude, #2 Non-technical, #3 They've actually broken that themselves.14:12
ltomasboyboaron_, sorry, I got connectivity issues...14:12
dmelladodulek: I've got a friend who once worked in some kind of 'internet access center for elderly people'14:13
* dulek guesses Internet is just broken worldwide today.14:13
dmelladowho quit after a couple of months14:13
dmelladobut shared some totally juicy stories such as14:13
dmelladodo 'double click' there14:13
dmelladoand they did that, they started to say 'click click'14:13
dmelladoall over14:13
dmelladoxD14:13
dmelladoso I guess that kind of work (1-2-3) could get to be stressful14:13
dmelladoltomasbo: you too? xD14:14
dmelladodid you try turning it off and on again?14:14
ltomasboalmost...14:14
dulekdmellado: I've also worked few months as an admin at the… social welfare home? Nursing home?14:14
dmelladooh, that ought to be tough as well xD14:14
dulekdmellado: So of course I was also asked to "take a look" at laptops of residents there.14:15
dmelladoOF COURSE xD14:15
dmelladowhich would of course too be full of malware and virus crap14:15
dmelladoand weird stuff14:15
dulekdmellado: Yeah. And you kinda suspect how they've got it.14:16
dmelladoyeah, 'kinda' xD14:16
dmelladodulek: I just hoped that they paid you *really well*14:16
dmelladofor that kind of job xD14:16
dulekdmellado: But I've also got to work with a blind guy that tried to learn using computer. He had all the screen reader software and memorized the keyboard on his own.14:17
dmelladowow, that's impressive!14:17
dulekThat was really a rewarding experience. I mean I'll never design a website or UI that'll be non-accesible.14:17
