jakeyipFYI: we just upgraded keystone to Rocky today and ran into problems with magnum. The symptoms are 503 in nova from occm. This is due to occm using a cached queens keystone token that is for some reason no longer valid in rocky keystone02:48
jakeyiprestarting minion generates a new token and fixes the problem. for clusters we don't control we are hoping to ride this out since occm asks for a new token every 6 hrs.02:49
flwangjakeyip: what do you mean 'restart minion generates new token'?03:44
*** sapd1_x has joined #openstack-containers03:45
jakeyipflwang: the error was something like this on the minion `Sep 18 01:47:52 kubedemo-qvk4skhj24o4-minion-0 runc[3646]: W0918 01:47:52.525502    3657 kubelet_node_status.go:974] Failed to set some node status fields: failed to get node address from cloud provider: The service is currently unable to handle the request due to a temporary overloading or maintenance. This is a temporary condition. Try again later.`03:45
flwangbut there is no token on the minion, but the credentials of the trustee user03:47
flwangso i don't understand why you need to restart the minion node03:47
flwangdid you try to restart the kubelet?03:47
flwangor recreate the occm pod?03:48

jakeyipRestarting minion is probably an overkill just the process will be enough. We were struggling to understand what and just restarted a demo cluster to be sure.05:41
jakeyip* a minion on a demo cluster that wasn't doing anything05:42

jakeyipI am here, is there going to be a meeting?09:07
flwang1jakeyip: not sure, seems strigazi is not around09:08
flwang1jakeyip: anything you want to discuss?09:08
jakeyipwondering what keystone vesion are you running flwang109:09
flwang1jakeyip: not sure if i'm allowed to mention that info09:10
flwang1what i can tell is it's an old version09:10
jakeyipok, just wondering if there was anything we could have done differently for the keystone upgrade09:11
flwang1jakeyip: ah, ok, but i missed your last message about why you have to restart the node09:13
jakeyipmaybe it's just something different in how keystone handle trust tokens between queens and rocky but doesn't matter09:13
jakeyipwe didn't have to restart node, restarting a process was probably enough09:14
flwang1jakeyip: ok, i see. anyhow, thanks for sharing09:18
flwang1what's your user feedback about magnum internally?09:19
jakeyipk8s is something everyone says they want... but pick up has been slow09:21
jakeyipprobably need more training materials09:21
jakeyipwhat about your side?09:23
*** ramishra_ has joined #openstack-containers09:25
*** ramishra has quit IRC09:26
flwang1we do have some customers are using it for production09:26
flwang1but overall, similar cases09:26
*** ramishra has joined #openstack-containers09:26
flwang1everyone like it, but it needs bigger  changes to use k8s into prod09:27
*** ramishra_ has quit IRC09:30
jakeyipyes I think a 'long running k8s cluster' needs to be a reality first. one that can survive upgrades and growing and shrinking number of nodes.09:34
flwang1jakeyip: yep, that's true09:41
jakeyiplet's call it a day since no one is here... I'm think I'm heading off09:49

guilhermesphello. I just applied this patch manually in my deployment ( master ) https://review.opendev.org/#/c/621734/ but seems that I still experiencing this http://paste.openstack.org/show/777441/17:38
guilhermespis there anyting else out of this patch that needs to be done?17:38
*** jmlowe has joined #openstack-containers17:44
brtknrguilhermesp: can you mention that in the review? also specify your deployment method?17:51
brtknrim testing that PS on devstack and works fine...17:51
guilhermespsure. I will comment17:52
brtknrguilhermesp: what is your deployment method?17:53
*** jmlowe has quit IRC17:53
guilhermespwe are deploying using openstack-ansible in a multinode environment. We get the source code and installs it in a virtualenv17:53
guilhermespjust commented brtknr17:59
brtknrguilhermesp: ah okay i am not familiar with that method. would you mind sharing the command you used to created the cluster/cluster template?18:01
guilhermespactually I'm creating using horizon gui brtknr but I can surely send you the cluster -template details in a minute18:04
guilhermespbrtknr: http://paste.openstack.org/show/777444/ and then I just create a cluster based on that template with 1 master and 1 node18:06
guilhermespthe flavors has 0 root disk btw18:07
brtknrguilhermesp: can you try with a flavor with non-zero root disk?18:08
guilhermespah I'm afraid I can, we are doing this in a production env and we can't right now create flavors with non-zero root disk =/18:14
guilhermespI can't*18:15
brtknrguilhermesp: oh!18:16
brtknrguilhermesp: this looks relevant: https://bugs.launchpad.net/bugs/183705418:17
openstackLaunchpad bug 1825020 in OpenStack Compute (nova) stein "duplicate for #1837054 resize of instance, that was booted from volume, trigger image size check then fails resize" [High,Fix committed] - Assigned to Matt Riedemann (mriedem)18:17
guilhermespah thanks brtknr we are running 19.0.2... I'm gonna double check heat + magnum and see if everything is in place18:26
guilhermespI will keep you informed and will update the patch set comment when I have some more news18:26
