mnaserstrigazi: I think this breaks flannel support - https://github.com/openstack/magnum/commit/2ab874a5be951a6eba4f9d4f54c106bc0c53d9b115:38
mnaseror maybe not, sorry, I jumped the gun15:38
mnaserI just can't get flannel networking to work, and the problem seems to be that one of the masters ended up with IP address: `10.100.0.0/16`15:39
mnaserwhich is a broadcast address15:39
mnaserthus unreachable15:39

mnaseralright, I think the issue here is that cni0 is missing in the master?18:35
mnaserok, `/var/lib/cni` is empty on master18:37

flwangdioguerra_: around?20:51
strigaziHello flwang brtknr ttsiouts, I won't manage to join today, sorry. flwang We can sync tomorrow after 09h00 UTC (in ~12 hours), I'll be online. mnaser I'll have a look tomorrow on flannel. I tested multimaster around 5 times for conformance, never saw this issue with single master.20:54
flwangstrigazi: ok, i can host today20:55
flwangstrigazi: i will ping you at 9h UTC20:56
mnaserstrigazi: I think it looks like flannel does not create cni0 if there are no pods/containers with hostnetwork: false21:03
mnaserso that was it I tihnk21:03
dioguerra_o/21:06
dioguerra_hello21:06
flwangdioguerra_: colin-: colby_: are you guys around for meeting? otherwise, i'm going to cancel this one21:06
dioguerra_yes we can talk fast21:07
flwangok, let's cancel today's meeting21:07
flwangdioguerra_: did you get a chance to revisit the auto scaling patch?21:07
colin-hi21:08
*** dioguerra__ has joined #openstack-containers21:08
colin-nothing to share today, am available if needed21:08
dioguerra__No, i can not. But i think it's a problem with devstack itself.21:09
dioguerra__Minion gets stuck on minion configuration21:09
flwangcolin-: all good, thanks21:09
dioguerra__Same happened when i tested multi dns21:10
flwangdioguerra_: ok, in my testing, it's all good21:10
dioguerra__i detected though that cluster-autoscaler crashes ofter with leader lost21:13
dioguerra__i don't know if both are related21:13
flwangdioguerra_: i don't think so21:14
flwangi think better clean up your devstack and recreate a new one21:15
dioguerra__i did21:16
dioguerra__still happens21:16
flwangdioguerra_: interesting, what's the error you got in the minion's cloud-init-output.log21:17
dioguerra__it does not create21:24
dioguerra__it fails in the minion init21:24
dioguerra__and you can't ssh to it do21:24
dioguerra__which is weird21:25
brtknrSorry to miss the meeting today! Completely lost track of time!21:25
flwangbrtknr: no worries, we decided to cancel it21:25
flwangsince we don't have enough ppl21:25
brtknrAh sorry to hear that!21:26
flwangdioguerra_: then i would say that's not related to the AS patch21:26
brtknrI have been busy with other things in the past week so havent been able to review/test many of the patches21:26
flwangbrtknr: but it's welcome if you have anything to discuss21:26
flwangno problem21:26
*** chhagarw has quit IRC21:27
colin-the topic of nodegroup came up today (internally) and i provided my most recent impression but wondered what the status of it is? i haven't looked in ~2w21:30
flwangcolin-: we still have 1 patch need to be merged21:31
flwangand the according client patch21:31
flwangbut that's just for NG itself, we do need a lot of work to support NG in other features, e.g. autoscaling, upgrade, etc21:32
openstackgerritFeilong Wang proposed openstack/magnum master: New config option for default Keystone auth policy  https://review.openstack.org/64322521:36
colin-understood, thanks for the update21:39
openstackgerritFeilong Wang proposed openstack/magnum master: Mount /usr/libexec/kubernetes/ for FlexVolumes  https://review.openstack.org/63806421:43
dioguerra_flwang: no, i think not21:44
jakeyipI've been lurking... have a question though - was there a plan to use keystone creds to connect to kubernetes web ui and is that working now?21:44
colin-you could use openstck coe cluster config to generate the credentials file that the kuberenetes dashboard would accept, if that's what you're trying to do?21:46
colin-(that would be authenticated via keystone)21:46
colin-do remember though that the default dashboard will allow you to click past the authentication challenge by default without offering any credentials, iirc21:46
colin-conversely, a valid JWT can be retrieved from the secret metadata for any service accounts created in the API21:47
jakeyipI'm aware of `coe cluster config` way. hmm, I think I was confused by commits for https://storyboard.openstack.org/#!/story/175577021:49
jakeyipdoes this allow access to webui or just kubectl or something else?21:50

flwangjakeyip: i don't think you can use the keystone based kubeconfig, but better try it by youself23:32
flwangjakeyip: now we can generate the kubeconfig based on keystone auth, so you can try to use it, personally i think it won't work because it depends on environment var23:33
