ricolin | strigazi, not necessary if you can get all to know that we're doing in here | 09:55 |

strigazi | Calico network driver for kubernetes, flwang1 do you want to say a few things about this faeture for ricolin slunkad and for the meeting record? :) | 10:06 |
*** janki has joined #openstack-containers | 10:06 | |
flwang1 | strigazi: yes | 10:06 |
flwang1 | catalyst cloud is trying to deploy magnum into production | 10:07 |
flwang1 | but to get a production ready k8s, we would like to have the network policy support | 10:07 |
flwang1 | which currently Flannel can't support | 10:07 |
*** jchhatba_ has quit IRC | 10:07 | |
flwang1 | so we'd like to upstream the Calico driver to achieve that | 10:07 |
flwang1 | https://review.openstack.org/540352 here is the patch i'm working on | 10:08 |
ricolin | #link https://review.openstack.org/540352 | 10:08 |
flwang1 | we'd like to get it in Queens if it's possible | 10:09 |
strigazi | flwang1: we will try to get it in | 10:09 |
flwang1 | strigazi: thank you for all the support | 10:09 |
strigazi | flwang1: do you need help for the software deployment? | 10:10 |
strigazi | me and ricolin can help | 10:10 |
ricolin | strigazi, yes boss! | 10:10 |
flwang1 | strigazi: i will push a patch tomorrow and please review it and feel free to post a patch set | 10:10 |

*** vijaykc4 has quit IRC | 10:14 | |
strigazi | speaking of the heat-agent, ricolin what about that patch on passing the public_url? | 10:14 |
ricolin | was stuck by releases job, but hope I can get it out these two days | 10:16 |
*** pengdake_ has quit IRC | 10:16 | |
strigazi | ricolin the patchset that is up now, is it working? | 10:16 |
ricolin | strigazi, which one you mean? | 10:16 |
strigazi | I though you pushed a patch already | 10:17 |
strigazi | I thought you pushed a patch already | 10:17 |
ricolin | strigazi, I sould, but not yet | 10:17 |
strigazi | ricolin :) ok | 10:17 |
ricolin | It will help if we can use k8s gate in upstream | 10:18 |
strigazi | ricolin: what do you mean? | 10:18 |
strigazi | I think the our k8s job should work now | 10:18 |
ricolin | strigazi, maybe some plan in PTG to discuss how we can do with magnum-functional-k8s? | 10:19 |
strigazi | ricolin there is nothing we can do on openstack-infra | 10:19 |
strigazi | the five only m1.large vms but most importantly they don't give us nested virtualization | 10:20 |
strigazi | A reasonable environament needs to have, 15GB ram, 8 or 16 cores at least 100 GB disk and *nested* virtualization | 10:21 |
strigazi | multinode would work as well but we still need nested virtualization | 10:21 |
ricolin | strigazi, is current infra even get any environment that can do nested virtualization? | 10:22 |
strigazi | ricolin: no | 10:22 |
strigazi | I asked multiple times | 10:22 |
ricolin | okay:( | 10:22 |
*** trinaths has joined #openstack-containers | 10:22 | |
strigazi | I tried to do smth in centos-ci but I was stuck and didn't have more time for it | 10:23 |
strigazi | let's move on | 10:23 |
strigazi | kubernetes python client and eventlet incompatibility https://github.com/eventlet/eventlet/issues/147 | 10:23 |
strigazi | I'm repeating this, and I will add to the release notes | 10:23 |
strigazi | the periodic task to collect metrics from the cluster is broken | 10:24 |
strigazi | and it also breaks the task that syncs the cluster status with heat | 10:24 |
strigazi | flwang1: this is the task (the metrics one) that we want to use for cluster healing | 10:24 |
flwang1 | strigazi: ok | 10:25 |
strigazi | But most importantly, it breaks the sync with heat, so cluster are in create_in_progress forever | 10:25 |
strigazi | we will have a parameter to disable that task, so magnum will continue to work normally | 10:26 |
slunkad | is there a patch for this already? | 10:26 |
strigazi | slunkad for the parameter yes | 10:27 |
flwang1 | strigazi: is it only impacting master branch? or Pike as well? | 10:27 |
flwang1 | can we bump the eventlet version? | 10:27 |
strigazi | flwang1: master only. Eventlet hasn't fix the problem yet | 10:28 |
strigazi | flwang1: by disabling the task, magnum works fine. At the moment you only lose the send to ceilometer metrics part | 10:29 |
flwang1 | strigazi: ok. can't we bump(skip) that eventlet version in requirements? | 10:29 |
-openstackstatus- NOTICE: Our Zuul infrastructure is currently experiencing some problems and processing jobs very slowly, we're investigating. Please do not approve or recheck changes for now. | 10:29 | |
flwang1 | strigazi: i see. | 10:29 |
strigazi | the problem is in kubernetes 4.0.0 | 10:29 |
flwang1 | can you paste the link of the patch disabling the task? | 10:29 |
strigazi | #link https://review.openstack.org/#/c/529098/ | 10:30 |
*** vijaykc4 has joined #openstack-containers | 10:30 | |
flwang1 | strigazi: cheers | 10:30 |
strigazi | flwang1: olso.messaging depends on eventlet | 10:31 |
strigazi | flwang1: kubernetes depends on multiproccsing | 10:31 |
strigazi | eventlet and multiproccsing are incompatible | 10:32 |
flwang1 | ok, thanks for the clarification | 10:32 |
strigazi | we can use python requests directly, but this way we re-write the kuberntes client | 10:33 |
*** vijaykc4 has quit IRC | 10:33 | |
*** vijaykc4 has joined #openstack-containers | 10:33 | |
strigazi | or we can use kubectl, the binary. that is even worse | 10:33 |
flwang1 | strigazi: TBH, i don't think magnum has to send metrics to ceilometer | 10:34 |
strigazi | it doesn't | 10:34 |
flwang1 | i mean the function even shouldn't be a part of magnum ;) | 10:34 |
strigazi | history | 10:34 |
flwang1 | history | 10:34 |
strigazi | in any case, we will need the client at some point for cluster healing and monitoring from magnum server to the clusters | 10:35 |
strigazi | next, | 10:35 |
strigazi | Cluster Federation https://review.openstack.org/#/q/status:open+project:openstack/magnum+branch:master+topic:bp/federation-api I'm tesing this and I'll try to take it as experimental api | 10:36 |
flwang1 | yep, agree | 10:36 |
strigazi | and I'll try to do the same with cluster upgrades | 10:37 |
ricolin | +1 on that | 10:37 |
strigazi | I'll ping you for testing | 10:37 |
strigazi | for upgrades mostly | 10:37 |
strigazi | I'm trying to clean my patches | 10:37 |
strigazi | Finally, to move to f27 | 10:38 |
strigazi | there is a patch to run etcd in a container: | 10:38 |
strigazi | #link https://review.openstack.org/#/c/524116/ | 10:38 |
strigazi | I'm also finishing the patch for flanneld | 10:38 |
strigazi | f27 doesn't have flanneld and etcd installed | 10:39 |
strigazi | do you have any questions? | 10:39 |
strigazi | ok, let's move on | 10:41 |
strigazi | #topic Open Discussion | 10:41 |
*** openstack changes topic to "Open Discussion (Meeting topic: containers)" | 10:41 | |
flwang1 | i'd like to get you guys opinion on this bug https://bugs.launchpad.net/magnum/+bug/1746961 \ | 10:41 |
openstack | Launchpad bug 1746961 in Magnum "Support enabled drivers" [Undecided,New] - Assigned to Feilong Wang (flwang) | 10:41 |
*** trinaths has quit IRC | 10:42 | |
flwang1 | as I mentioned above, Catalyst Cloud would like to deploy magnum, but we just want to support k8s for now | 10:42 |
flwang1 | so we don't want to receive any support ticket about any other driver | 10:42 |
flwang1 | so we have a way to do that now? | 10:42 |
strigazi | at the moment, you can update the magnum python egg and remove the entrypoints | 10:43 |
*** trinaths has joined #openstack-containers | 10:43 | |
ricolin | wondering will it work if we replace the template:) | 10:43 |
strigazi | ricolin: which template? | 10:43 |
slunkad | does it make sense to have config options that disables the drivers? | 10:44 |
flwang1 | strigazi: which is hard for us because we're building virtual env for different services | 10:44 |
flwang1 | slunkad: that's the thing i'm trying to propose | 10:45 |
ricolin | strigazi, I mean remove the templates under each driver | 10:45 |
strigazi | ricolin that is also possible, | 10:45 |
strigazi | flwang1: we can do this as well | 10:45 |
flwang1 | ricolin: but that way also need to change source code | 10:46 |
strigazi | have enable_drivers or use the definitions | 10:46 |
ricolin | flwang1, yes | 10:46 |
flwang1 | strigazi: yep, https://github.com/openstack/magnum/blob/master/magnum/conf/cluster.py#L25 | 10:46 |
flwang1 | should we reuse the existing config option or create a new one? | 10:46 |
strigazi | flwang1 let's do new one | 10:48 |
ricolin | IMO better a new one if that's for disable drivers | 10:48 |
strigazi | flwang1: enabled_definitions is there but unsued anyway | 10:48 |
ricolin | you will need to keep the backward consist | 10:48 |
strigazi | no, enable drivers | 10:48 |
flwang1 | so you all happy to have a config option for this user case? | 10:48 |
strigazi | ricolin it is silently ignored already | 10:48 |
strigazi | ricolin: since ocatra | 10:49 |
strigazi | ricolin: since ocata | 10:49 |
ricolin | strigazi, okay, then it will be fine | 10:49 |
strigazi | flwang1: yes, we can add enable_drivers | 10:49 |
slunkad | +1 | 10:49 |
flwang1 | strigazi: cool, thanks | 10:49 |
slunkad | strigazi: this is building locally now https://review.openstack.org/#/c/520063/13 | 10:51 |
slunkad | but I need some +1s on https://review.openstack.org/#/c/539619/ so it is merged and we can test it in gating | 10:51 |
strigazi | slunkad ok | 10:52 |
slunkad | also if you have some time can you give this https://review.openstack.org/#/c/507522/ a code review? | 10:52 |
strigazi | slunkad: I'll have a look | 10:52 |
slunkad | strigazi: and ofc we still need the kubernetes elements in the image.. | 10:53 |
slunkad | thanks! | 10:53 |
strigazi | slunkad I know :) | 10:53 |
strigazi | slunkad: if you have a working image we can take https://review.openstack.org/#/c/507522/ , you will be the ones that will mostly use it initially | 10:54 |
slunkad | strigazi: I do have a SLES based image which I uses for testing which I can't make public | 10:55 |
strigazi | ok | 10:55 |
slunkad | strigazi: not sure if everyone is comfortable merging it for now without the image.. | 10:56 |
strigazi | it's a start, I think if we build an image even locally and publish it, we can start | 10:57 |
flwang1 | slunkad: i'm sorry, but if that's the case, do we really need to move the driver into main tree? | 10:57 |
slunkad | strigazi: ok then I will try that, thanks | 10:58 |
slunkad | flwang1: we are working on a opensuse based image so we will have a image soonish | 10:58 |
strigazi | flwang1: with a working image published we can start | 10:58 |
strigazi | flwang1: we zero options avaialble publicly we can't | 10:59 |
strigazi | with zero options avaialble publicly we can't | 10:59 |
flwang1 | strigazi: thanks, that makes sense for me | 10:59 |

vabada | strigazi: in patch https://review.openstack.org/#/c/533593, in file kube-apiserver-to-kubelet-role.sh, can I ask why apiVersion: apiVersion: rbac.authorization.k8s.io/v1beta1 | 15:24 |
*** mnasiadka has quit IRC | 15:27 | |
tiswanso | Hi, I'm new to magnum (not new to openstack or k8s) and following the quick-start guide. The instructions work pretty much exactly for stable/ocata and I'm able to deploy pods/etc to k8s after creating a cluster per the example. For stable/pike (with fedora-atomic 26), the cluster creates with no errors but kubectl doesn't see the minion nodes and I'm unable to create deployments. Is there some extra RBAC st | 15:27 |
tiswanso | uff needed to get going? | 15:27 |

strigazi | DimGR: hello | 15:46 |
strigazi | vabada: i guess you ask why beta right? | 15:46 |
strigazi | vabada: i did it for 1.7 which was beta | 15:47 |
strigazi | tiswanso: is cluster status CREATE_COMPLETE? | 15:47 |
strigazi | tiswanso: check in the node if kubelet is running | 15:48 |
strigazi | tiswanso: I think we have a bug and you need to add --requure-kubeconfig to fix it | 15:48 |
strigazi | tiswanso: the patch is coming | 15:48 |

vabada | strigazi ok thanks. so this way we keep backwards compatibility? so it works with 1.8 as well? And in addition, if you let me know some useful testing I could do for that patch, that'd be great | 16:02 |
tiswanso | strigazi: yep... everything from cluster create looks good (CREATE_COMPLETE) | 16:02 |
tiswanso | I'll read about require-kubeconfig | 16:03 |

strigazi | ps aux | grep kubelet there is probably a process somewhere hanging | 16:44 |
tiswanso | don't see one. with grep kube, just see kube-proxy, flaneld | 16:45 |
strigazi | do systemctl stop kubelet | 16:45 |
strigazi | then systemctl cat kubelet and execute the execstart command | 16:46 |
tiswanso | I added a comment to that gist with the output: https://gist.github.com/tiswanso/459f78f5156639c69f70182fe9872362 | 16:50 |
tiswanso | openstack cloud-provider issue? | 16:51 |
strigazi | Error: failed to run Kubelet: could not init cloud provider "openstack": Resource not found | 16:51 |
strigazi | yes | 16:51 |
strigazi | tiswanso: it a bug in the cloudprovider | 16:51 |
*** mnasiadka has joined #openstack-containers | 16:52 | |
strigazi | you can disable the provider if you want or do some changes in your env | 16:52 |
tiswanso | strigazi is cloud-provider built into the cluster image? | 16:52 |
strigazi | are you in devstack? | 16:53 |
tiswanso | yes... devstack | 16:53 |
strigazi | you can add redirection for the keystone endpoints | 16:53 |
*** jmlowe has quit IRC | 16:53 | |
strigazi | centos or ubuntu? | 16:53 |
*** gsimondon has joined #openstack-containers | 16:53 | |
*** jmlowe has joined #openstack-containers | 16:53 | |
tiswanso | could I just pull a known good fedora-atomic image? | 16:53 |
strigazi | tiswanso the problem is not in the image | 16:54 |
tiswanso | my devstack base is ubuntu xenial | 16:54 |
tiswanso | strigazi ok cool | 16:54 |
strigazi | tiswanso: https://github.com/openstack/magnum/commit/674b90548d35b0f311b7c1f39cb5b5a6fd085eeb | 16:54 |
strigazi | tiswanso: you need to add redirection from v3 to /identity/v3 | 16:55 |
strigazi | tiswanso: then it will work | 16:55 |
tiswanso | ok great... I'll do that, thanks! | 16:55 |
