gdubreuiHello, Using neutron client, I've an issue where it times out - Debug mode shows the controller sends the token but tell the client to connect to neutron api via private IP so that fails.01:32

sgranmorning.  Just curious if anyone had any feedback on my questions from last night?05:45
lifelesssgran: what was your questio?05:55
sgranlifeless: http://paste.debian.net/61098/05:57
sgranand thanks05:57

openstackgerritChristian Berendt proposed a change to openstack/python-neutronclient: change assert_ to assertTrue  https://review.openstack.org/5351706:07
lifelessthe stingray aspect I'm naive on, but what you say sounds plausble06:14
*** jlibosva has joined #openstack-neutron06:14
lifelesssecurity groups - hmm, yes, I think there is no dest host field on ingress rules - you'd need to enhance neutron to support that06:14
lifelessthe current model is that security groups apply at the port level: they are intended to handle host firewalls06:17
lifelessI think it's reasnoable to extend them to be more granular06:17
lifelesssgran: that said, for a load balancer there are dedicated LBaaS and FWaaS APIs that perhaps model whats going on better?06:19

sgranlifeless: yes, I'm planning to use the LBaaS API to actually configure the stingrays06:40
sgranhttps://review.openstack.org/#/c/53429/06:40
sgranbut we're making it awkward on ourselves by running the stingrays as instances in openstack :)06:40
lifelesssgran: ah06:41
lifelesssgran: is a stingray regular hardware?06:42
lifelesssgran: or will it be running as a VM ?06:42
lifelesssgran: ... or is it custom hardware?06:42
sgranthey do a couple of different things - hardware appliances, VM images, and just a software install06:42
sgranwe're running the VM images in this implementation06:42
lifelessok06:42
lifelessLBaaS in VMs is fine06:43
lifelessthe thing that will be awkward is doing filtering via security groups06:43
sgranthe general idea is that we'll bring up a clustered pair ahead of time, and then use the LBaaS API to configure them for serivces06:43
lifelessI'm not sure it's good fit to the problem of dynamic rulesets LBs normally have06:44
sgranbut there are a few load balanced services where we'd like to restrict access to the VIP to a few instances/subnets/whatever06:44
sgranif we could destination filtering, it would be straight forward06:44
sgranwe'll probably have to bring up new pairs with different security groups instead for now06:44
lifelessif the permitted users are in the same cloud you could allocate a dedicated virtual network for it06:45
lifelessor, enhance security groups :)06:45
lifelessshouldn't be too hard - security groups are already much more general than nova's thing, which was limited in much the same way AWS's facilities are06:45
*** hua has joined #openstack-neutron06:49
sgranwe're trying to flatten things out for now :)  we currently have too much complexity in our networking06:50
sgranlifeless: nod, I think that might be on my list, then06:51
sgranshould I implement it as an extension at first?06:51
*** markmcclain has quit IRC06:51
*** gdubreui has quit IRC06:53
*** bvandenh has joined #openstack-neutron06:54
lifelesssgran: pretty much everything in Neutron is an extension06:54
lifelesssgran: If I was doing it I'd start by evolving the existing security group stuff06:54
lifelesssgran: get a POC up and then see what -core folk think06:54
sgranok, thanks06:56

sgranlifeless: one more question, if you have a moment08:14
lifelesssgran: sure08:14
sgranin doing this, I'll be adding vips to instances08:15
sgranI think the best way to deal with this is to use the allowed-address-pair extension08:15
sgranbut I'm wondering about how to plumb that in08:15
sgranI was wondering if I want a dummy interface driver that does that?08:15
sgranor a callback handler on the server plugin that does this once the vip is configured on the load balancer?08:16
lifelesslet me see if I can paraphrase08:16
lifelessyou're asking what should make the port-update/port-create call on your LB instance ?08:17
sgranalmost08:17
sgranI will have one port08:17
sgranand vip creation/deletion will add addresses to this port08:17
lifelessAFAIK Nova doesn't let you request arbitrary parameters for networks08:17
*** nati_uen_ has quit IRC08:17
lifelessthat may have changed since I last read the code of course08:17
lifelessso you're going to need to use update-port on the port nova creates08:18
sgranoh, yes, indeed08:18
*** nati_ueno has joined #openstack-neutron08:18
sgranI just mean I won't be creating a new port for each vip address08:18
lifelesswhat will trigger vip creation/deletion ?08:18
lifelesssgran: right, I was exploring the problem :)08:18
sgranwhen a user calls the LBaaS API to create a new lb pool/vip/member combination, I'll call the rest API on the stingray to configure those08:19
sgranthat part is fine08:19
sgranthe complication comes from running them as instances, which get the normal anti-spoofing rules08:19
lifelessthat seems to be when you want to call neutron to poke the vip in08:19
lifelessyou could either have the stingray enable itself08:20
lifelessor have the LBaaS api engine do it08:20
lifelessor you could emit a message on the bus and have a dedicated service do it08:20
lifelessI'd be inclined to have the LBaaS api do it08:20
lifelessbecause it's the thing maintaining your source of truth about the LB configuration08:20
sgranyes, that's my inclination as well08:20
*** gdubreui has joined #openstack-neutron08:20
lifelessconsider what should happen if you spin up a new stingray08:21
sgranok, I'll have the neutron API do the port update.  That seems simplest08:21
sgrannod, yeah, I am :)08:21
lifelessit should get configured up - both stingray stuff, and nova/neutron, to be like the others, and then put in rotation08:21
sgranyeah, I think I'll make port update/delete iterate the list of instances08:22
sgrancool, thanks08:22
*** nati_ueno has quit IRC08:22
lifelesssgran: anytime :)08:23
layer427expertThis the advanced service framework should if it is designed correctly eliminate the need to spin up new ports for each VIP08:33
