flwangstrigazi: how can i help?21:58
strigaziflwang: hello22:37
strigaziflwang: you there?22:38
flwangstrigazi: yes22:38
strigaziflwang: Can you have a look into Use existing templates for cluster-update command  https://review.openstack.org/600806 ?22:38
flwangstrigazi: what do you mean 'existing templates'?22:39
strigaziflwang: Also the patch to use the kubernetes client for the health status is not python 3.6 compatible22:39
strigaziflwang: stack update --existing22:39
flwangstrigazi: ok, will do. we need it for rolling update feature, right?22:39
strigaziflwang: not only, the biggest issue is that if you have running clusters. Say a k8s cluster built with magnum version x.y.z, then you update magnum to x.y.(z+1) where the z+1 has a change in the heat templates that go into vm user-data, and if the user tries to scale the cluster when magnum is z+1, the stack update is desstructive, it replaces vms.22:42
flwangstrigazi: ah, i see. will take a look then.22:43
flwangstrigazi: as for the health status patch, if it's a really compatible issue, then we may have to drop the k8s client totally22:43
flwangthough i don't want to22:44
*** rcernin has joined #openstack-containers22:44
strigaziflwang: for the patch to sync the cluster health with the k8s client, I don't know if there is a solution. We can investigate22:44
strigaziI think when use a sigle process it is fine.22:45
strigaziflwang: in my multicore laptop breaks, in a single vm it works22:45
strigaziflwang: in my multicore laptop breaks, in a single-core vm it works22:45
flwangstrigazi: interesting, in my laptop it just works22:54
