brad_behleCan someone point me to any documentation about running Octavia in containers?  I'm looking for options for an environment where thousands of load balancers are required, and don't want the overhead 1 GB of mem per Octavia service VM per load balancer19:58
*** yamamoto has quit IRC20:01
dougwigblogan: any material on rax's usage?20:04
bloganbrad_behle: so you want octavia to spin up containers instead of VMs?20:04
bloganto host haproxy?20:04
*** Purandar has joined #openstack-lbaas20:05
brad_behleblogan: Yeah, looking for any way to get a more lightweight implementation for Neutron LBaaSv2 load balancers.  A full VM seems like overkill resource wise, and I thought I read in one doc that containers were the proposed answer to that.20:05
brad_behleblogan: but I'm open to other suggestions for getting lightweight load balancers20:06
bloganbrad_behle: do you plan on using magnum for this? or any container service that works for you?20:07
bloganbrad_behle: reason i ask is right now its only built for nova VMs and neutron right now, but we all do want container support20:07
bloganbrad_behle: what dougwig said about trying to get the agent driver in for free is true20:08
brad_behleblogan: no preference here as far as container service20:08
bloganbrad_behle: but i think a better option would be a container driver20:08
bloganand we were planning on doing it all on containers here at rax, but that got shelved and we've pivoted back to VMs for now20:08
dougwigthe nova-compute-lxd path might also be interesting, as it'd work with our current nova-centric implementation.20:09
bloganso the obvious solution woudl be to use magnum, BUT magnum isn't really what we want, we basically want a nova service taht spins up containers instead of VMS and we don't have to worry about anything else20:09
blogandougwig: yeah, i dont know much abou tit, but if its exactly like the nova api and also supports hot plugging, it'd work20:10
*** anilvenkata has quit IRC20:11
bloganbrad_behle: there's also an effort underway to reduce the size of the image needed for VMs because 1 GB is asking a lot20:11
bloganbut still, containers is the future, its just a matter of getting there20:11
bloganof course we could just write our own container scheduling service and reinvent the wheel there a bit20:13
brad_behleblogan: So what makes you say that a container driver would be better than the existing namespace HAProxy driver?20:13
xgermannamespace haproxy is a) deprecated b) not reliable (no failover) and c) doesn’t scale20:14
bloganbrad_behle: noisy neighbor can be better mitigated with containers, unless i'm unaware of something20:14
bloganxgerman: a and b can be fixed, c is debatable still, not sure that's ever been accurate20:15
bloganin fact there are patches up rgiht now that are improving the v2 agent that i've been meaning to get around to reviewing20:15
xgermaneverything can be fixed ;-)20:17
brad_behleblogan, xgerman: do you know of any scaling limits or data on number of load balancers with either the namespace HAProxy or the Octavia drivers?20:19
xgermanOctavia doesn’t have any limits by design - namespace will probably eventually bump up against the RabbitMQ limits (and scaling Rabbit is hard)20:20
xgermansince you use Neutron’s queue if you crowd out the Neutron messages your system might not work properly20:21
bloganbrad_behle: like i said above i'm not sold taht teh namespace driver isn't scalable, so i ahve no numbers for that, octavia will provide horizontal scalability once the active active feature gets in20:22
bloganbut it already supports ha which the namespace driver does not, but thats obviously something that could be fixed20:22
bloganxgerman, johnsom, and sbalukoff probably know more about the namespace driver limits than I do though, they've either attempted to run it in production or have20:24
xgermanI have had bad luck with queues a few time so I am skeptical at they infinite scaling pitential20:25
bloganwell octavia does use queues!20:25
bloganapi -> queue -> cw20:25
xgermanyeah, but we also use HTTP to the amphora and UDP for status20:26
xgermanwhereas in namespace everything runs over the queue20:26
*** Purandar has quit IRC20:26
xgermanqueues in general hate too many messages and too many subscribers20:27

xgermanyeah, I think it survived the last summit somehow20:57
xgermanbut since it’s not the reference implementation support is slim and some features are not implemented (L7?)20:57
brad_behleblogan, xgerman: But I think namespace HAProxy driver is supported in LBaaSv2, right?  The advanced networking guide describes two options, one is Octavia and the other is the HAProxy Agent driver20:58
