mfedosinsudipto_: hey!08:26
sudipto_mfedosin, hello!08:27
mfedosinmay we discuss zun features? :)08:27
sudipto_Sure - go ahead :)08:27
mfedosincool08:27
mfedosinso, let me briefly describe our use case08:27
sudipto_Sure08:27
mfedosincurrently we have nfv in vms08:28
mfedosinand they are managed by Nova08:28
mfedosinbut we're not satisfied by the performance08:28
sudipto_Albite.08:28
sudipto_(pardon my auto corrections)08:28
mfedosinand we are considering to put it all in containers08:29
mfedosinin other words we need container “drop-in” replacement for VMs in NFV08:29
sudipto_gotcha!08:29
mfedosinfrom short investigation we found 3 projects in openstack08:30
mfedosinnova-docker, which seems dead08:30
mfedosinand then Magnum and Zun08:30
*** GB21 has quit IRC08:31
*** Namrata_ has quit IRC08:31
sudipto_Yeah - so when you say "drop-in" replacement, what are you exactly looking at?08:31
mfedosinfrom short investigation I got that Magnum is manager of COEs (kubernetes or swarm) and Zun is kind of lite COE itself08:31
mfedosinwe want to get rid of vms, put all workloads in containers and has the ability to manage them as before08:33
sudipto_do you want to convert the VMs into containers - with a certain downtime?08:33
sudipto_you are fine with the re-provisioning your applications inside containers?08:33
mfedosinI think we're fine with reprovisioning08:34
sudipto_Ok - basically at this stage, zun hasn't had a first release but we are aiming for one shortly. Our main motivation is to ensure that you have a single pane of management software to manage both your VMs and containers - where all the same management rules would apply.08:35
sudipto_ZUN at the moment works with only docker APIs and has plans to support various COE APIs in the future (subjective to design discussions).08:36
mfedosinthat's good, exactly what we need08:36
pksinghmfedosin: happy to know, you found Zun interesting :)08:37
sudipto_Basically - ZUN would get you containers in openstack...by being a self sustaining project, which takes inspiration from nova-docker but is a not more expansive than that.08:37
sudipto_s/not/lot08:37
mfedosinfrom my perspective: now there is a vm(s) with workloads, we need to create a set of containers, combine them in a pod (in terms of kubernetes) and then provide a service to end users in the same manner as it was with vms08:38
mfedosindoes zun provides features like load balancing or auto-healing?08:39
sudipto_Ok - we don't quite support the PODs as yet, but we have a concept of a container sandbox that the broader set of the team (lead by honbin) is working on. The sandbox would be built with the idea of providing the "service" concept of kubernetes.08:39
sudipto_ZUN at the moment, isn't a full fledged COE - hence load balancing and auto-healing are not supported yet.08:40
sudipto_We have currently built the support for the primary docker APIs and are working out the integration pieces with various other openstack projects that include glance/neutron etc.08:40
mfedosinokay, I think we can live without some features for the first time08:40
mfedosinespecially since it's an r&d project :)08:41
sudipto_you are a BIG welcome to contribute :)08:41
sudipto_mkrai, ^ I hope i have captured the points correctly :)08:41
mfedosinthanks! I think I will08:41
*** Namrata_ has joined #openstack-zun08:42
mfedosinalso what about multitenancy? do you have isolation for containers?08:42
sudipto_I would have hongbin comment on the multi-tenancy feature - if you want the exact details on where we are with it at the moment08:42
sudipto_hongbin works out of Canada, and is online during your evening time probably :)08:43
sudipto_but i do remember, having a discussion around that.08:43
mfedosinokay, I'll ask him today08:45
mfedosinbtw, are you familiar with magnum? does it support coe deployment not in vms?08:45
sudipto_AFAIK, magnum supports COE deployment via NOVA on the VMs.08:45
sudipto_There are quite a few developers of magnum on this channel, hopefully they will correct me, if i am wrong :)08:46
mfedosinseems so, but there were discussions about bare-metal08:46
sudipto_Qiming, ^08:46
*** GB21 has joined #openstack-zun08:47
mfedosinokay, it seems it's enough for me for beginning :) I deployed devstack with zun and going to play with it08:49
mfedosinthanks sudipto_! if I have questions I'll ask you later :)08:49
sudipto_awesome.08:49

mkraimfedosin: Hi09:00
mkraiYou might be interested in having a look at this09:01
mkrai#link https://blueprints.launchpad.net/zun/+spec/support-secure-container09:01
mkraiWe are aiming to support clear container or hyper container to zun09:02
pksinghmkrai: gate jobs are not running for https://review.openstack.org/#/c/400045/, any idea?09:02
mkraimfedosin: Also Magnum supports running k8s in baremetal09:02
mkraipksingh: Let me check09:02
mfedosinmkrai: thanks for the link, looks interesting09:03
mkraipksingh: #link http://status.openstack.org/zuul/09:05
mkraiseems a long queue. I am not sure may be Jenkins is not running09:06
pksinghmkrai: got it, yes its in queue09:07
pksinghthanks09:07

mfedosinmkrai: just on question about Magnum - afaiu it only deploys kubernetes cluster on vms or bare-metal and orchestrates it. So there is no api for managing kubernetes pods, services, etc.09:52
mfedosinand we should rely on kubernetes itself for these tasks09:52
mfedosinam I right?09:52
mkraiYes mfedosin right09:53
mkraiThere is no APIs to manage pods etc in Magnum09:54
mkraimfedosin: I think Zun will meet your requirements but it will take time09:54
mfedosinmkrai: thanks :)10:00
