Here I thought it was our company splitting.... 20:03:36 lol 20:04:21 lol johnsom, i think i put that first copy in there last week....apparently i was doing something stupid 20:04:44 anyway FLIP topic 20:04:52 I don't believe the others that were responding to the email threads are here. But they have brought up some additional ideas about how to handle/deal with floating ips that we are still discussing. There has not yet been a solidified agreement as of yet. 20:05:06 been a long email chain on the ML about it, people might need some time to get caught up on it 20:05:12 indeed 20:05:34 Yeah, it has been a busy week, so I am not caught up 20:05:39 ptoohill would you agree that the current plan to just have the user associate the FLIP to the vip port works for now and how to implement the autoallocation of the FLIP can wait until later? 20:05:50 Agreed 20:06:11 Later like v1.0? 20:06:14 This will require additional user interaction, but no additional work on our behalf. 20:06:25 Most likely 20:06:51 johnsom: well this would be more on the Neutron LBaaS side, so I'd say later as a feature to go into Neutron LBaaS along with the octavia driver 20:06:52 Yeah, I can agreed that it can hold for v1.0 time frame 20:07:14 Yep 20:07:19 Well, thats where some of the talks are leading though. 20:07:41 Vijay brought up having the octavia controller handle the creation/updates for flips 20:08:12 yeah but that has other issues when neutron lbaas is being used as a frontend 20:08:14 Though, this idea is being discussed right now and dont have much more info for the tiem being 20:08:20 agreed 20:08:29 so yeah everyone who has an opinion on it or wants more info, read the ML thread 20:08:36 ^^ 20:08:40 ok 20:08:43 I think we pull too much into Octavia, in general. 20:08:51 The controller seems like the logical place, we would just have to defer giving the FLIP to the user 20:08:52 dougwig: +1 20:09:36 There is definately good reasons for having it there, one is during the HA handling. But again, this is still in 'early' discussion and input on the ML is crucial 20:09:58 ptoohill: +1 20:09:59 pinged a user or keyword 20:10:02 ptoohill: +1 20:10:48 ptoohill: So are you thinking that the controller will calle the Networkign Driver which will call Neutron, etc 20:10:48 Ha fip handling is a good use case. But does not mean that all fip handling should be pulled in 20:11:14 sballe, that is indeed the idea from what i gather. 20:11:27 dougwig, what would be 'all'? 20:11:33 sballe: if octavia were to do its own flip allocation then yeah that would happen 20:11:52 blogan: I am not sure we want that right? 20:12:08 does this mean we'll have standy octavia instances for HA that just need a FLIP associated to go active? 20:12:42 sballe: do you prefer the scenario where a user creates their own flip and associates it with a port? or you prefer neutron lbaas to do the flip allocation? 20:13:11 rohara, that's a good question. That depends if we are having active-active set up, then associating a flip is all that is needed for it to go active. 20:13:47 ptoohill: right. i like that approach. 20:15:13 to me the right steps are 1) only allow user to associate flip to neutron lbaas vip port 2) neutron lbaas auto allocates flip and associates on behalf of user 3) investigate whether we want this in Octavia 20:15:37 2 being configurable in neutron lbaas 20:16:24 anyone disagree? 20:16:51 Going forward that sounds like a good plan. 20:17:04 +1 20:17:07 okay moving on to next topic then 20:17:16 #topic Reviews Needing Attentions 20:17:44 #link https://review.openstack.org/#/c/127337/ 20:17:52 sballe's Workflow diagram 20:17:55 #link https://review.openstack.org/#/c/127353/ 20:17:58 ^^ possibly interesting 20:18:42 though as blogan points out, probably more relevant to neutron-lbaas 20:19:06 yeah you've lost your link permissions 20:19:14 blogan: I will work on fixing them this weekend. I have been traveling 20:19:30 sballe: np, i just wantedt o get some attention on it so others take a look 20:19:35 thanks 20:19:41 also sbalukoff's amphora api spec 20:19:43 #link https://review.openstack.org/#/c/126801/ 20:19:48 taht needs some eyes as well 20:20:04 of course he's out this week so he won't be able to respond until he gets back 20:20:24 I'm in the middle of reviewing that one right now.. he's asked me to actually do the coding for it.. so I'm trying to really think it through and point out anything that is ambigous 20:20:41 haha davidlenwell, you fell into his trap 20:21:04 well .. i also work with him and have been asked to make this a priority 20:21:12 but yes 20:21:47 http://i3.kym-cdn.com/photos/images/facebook/000/001/384/Atrapitis.gif 20:21:54 :P 20:22:24 lol 20:22:34 any other reveiws people want attention on? 20:23:21 okay moving on 20:23:29 #topic Usage requirements 20:23:34 I'll take this one 20:23:38 some of you may remember jorgem 20:23:46 he's back from management hell 20:23:49 What is Octavia again? lol jk 20:24:17 I will probably add this to the ML but I have some ideas for usage as I am currently building out usage requirements with Tom 20:24:52 Since we are planning on using TCP, HTTP based protocols I wanted to entertain the idea of capturing logs to accurately record usage 20:25:15 do we ever plan on support UDP load balancing? or is that a running joke? 20:25:17 I wanted to do this on our internal LBaaS product but we offer UDP which like 2 people use 20:25:26 so I couldn't do it 20:25:39 Using connection logs has other advantages too 20:26:10 I thought some were quite serious about supporting UDP. 20:26:38 such as 1) Accurate recording of inbound and outbound traffic 2) Accurate assessment of concurrent connections, etc. 3) Serves as a debugging aid ... 20:26:38 it always feels like a joke, but haproxy doesn't even support it 20:27:13 4) Mitigates uncertainty into capacity management since every lb will have connection logging on by default 20:27:26 Agreed, and that's correct, we would have to use other tools to accomplish it. 20:27:34 Anyways, now that I'm typing furiously I think this is better for the ML 20:27:40 lol 20:27:43 yes probably 20:27:51 We could send UDP over TCP right? right?... guys? 20:28:09 TrevorV: negative 20:28:24 UDP healthchecks are a pain 20:28:26 UDP is non-realiable TCP is 20:28:36 sballe, johnsom: do you know exactly what usage requirements you have? 20:28:48 Interesting idea, I am just wondering about approaches to handle the log processing load 20:28:50 as in what metrics you need to capture, how often, etc 20:28:51 This model only works with protocols that allow connection logging so UDP is out of the question. 20:29:13 We don't have to perform a map-reduce or anything since logs will be isolated per lb 20:29:16 man, you guys are a bunch of udp haters. 20:29:19 :) 20:29:21 hehe 20:29:29 if we do want UDP this won't work 20:29:35 at least for UDP lbs 20:29:40 dougwig: maybe you should marry udp if you love it so much 20:29:54 i embrace the uncertainty. 20:29:58 I've done several usage gathering iterations and this is by far the simplest and most accurate 20:30:09 +1 for embracing the uncertainty 20:30:34 but can the large load this will incur be handled easily? 20:30:36 anyways, let's debate this on the ML. I just wanted to get it out there and see if there were any immediate objections 20:30:45 I have not yet put a lot of thought into the usage requirements. There has been some talk about ceilometer being the end destination, but not much about collection. 20:31:13 correct, I think the end desitination will be, dare I say it, configurable. 20:31:20 johnsom: wouldn't you need something similar to what libra does? 20:31:21 Someone here had talked about collecting inbound/outbound from iptables 20:31:32 sbalukoff was i believe 20:31:53 That's one way but you would have to poll I think 20:32:00 polling == complex 20:32:20 doable but logs is waaaaaay easier 20:32:38 Being new to the group, I tend to be "legacy" free when it comes to libra 20:32:47 * TrevorV thinks the more a's you use the more accurate the statement becomes 20:33:04 johnsom: ah fresh mind 20:33:27 jorgem: what if a user disables logs? 20:33:41 glad you asked blogan. 20:33:45 I 20:34:04 I'm thinking that we just don't send them to swift in that case but keep them going on behind the scenes 20:34:11 for the other reasons I stated 20:34:36 operations will like to see logs in order to investigate problems 20:34:43 can't we get inbound/outbound from... neutron? 20:34:59 I'm talking apache style logs 20:35:06 or some other format 20:35:29 I had been thinking about "operator" logs vs. "customer" logs. I.e. security logs, etc. from the Amphora 20:36:03 Some people might want to charge separately for headers and some may not 20:36:15 This would make it easy to capture that and leave it to the operator to decide 20:36:21 but on rm_work's point, neutron would have the data of traffic passing through the network. assuming the do actually keep track of all the stats we need. Otherwise we would need to augment it 20:36:24 well I think we can all agree this needs more discussion on the ML 20:36:34 correct. 20:36:37 so jorgem, make a thread 20:36:43 Yes, but good topic 20:36:52 #action Jorge to start thread on usage requirements 20:37:04 moving on 20:37:10 #topic progress reports 20:37:20 so I know we have the weekly ehterpad, that I apparently messed upa bit 20:37:42 but I'm just curious if there are any issues with any bps that have assignees 20:38:10 sot eh operator-api one trevor and I ahve been working on is almost done, but some issues need to be ironed out 20:38:26 I'm about to start on integrating Barbican with Octavia, assuming that's in 0.5, otherwise I'll wait a bit :P 20:38:28 sbalukoff has the appliance-api BP which he has a spec out for that was linked above 20:38:58 Until this week I had been making progress on a first draft for the controller spec. I want to have something to throw out there and catch arrows while I code on the image build scripts. 20:39:13 arrows in the knee? 20:39:59 Among other places I am sure.... 20:40:02 johnsom: i didnt include the controller bp because it is blocked by many sub components, so i figured it'd be a while anyway 20:40:36 Yeah, but I think there were be a lot of discussion so having a starting point is probably good. 20:40:46 definitely 20:41:07 how is the base image coming along? 20:42:15 I have done some experimental images and have a good line of sight on the code. I just prioritized a first draft of the controller spec. 20:42:30 okay cool, just wanted to get an idea 20:42:38 If it is a blocker, I can re-order 20:43:03 btw for everyone, don't be afraid to put experimental code in gerrit as a WIP, i think that is a good chance for everyone to look at the code and give good feedback 20:43:06 I think everyone is essentially going to need to develop their own base images anyway... 20:43:21 i think a lot of people see WIPs as reviews that don't need eyes, but I think they should be looked at as much as possible 20:43:33 Al on our team also is almost done with a first draft of his spec. Has been moving this week 20:44:05 rm_work: yes but getting something we can actually run as a test deploy will be a big win, even if we at RAX will be using a different image 20:44:21 johnsom: thanks for the updates 20:44:22 yeah I guess a "devstack compatible" base image 20:44:23 rm_work: Agreed, but I hope these scripts will make a nice baseline for customization and testing 20:44:45 dougwig: any update on the networking bps? 20:46:47 i think he may be afk 20:47:11 #action dougwig give update on networking driver 20:47:18 #topic open discussion 20:47:45 anything anyone wants to talk about or just end meeting? 20:48:25 im going to take silence as end meeting 20:48:31 too soon 20:48:33 wait longer 20:48:36 no 20:48:37 lol 20:48:39 wait! 20:48:40 people can't all type as fast as we do 20:48:46 ok I'm done 20:48:56 3 20:48:58 2 20:49:00 7 20:49:00 1 20:49:02 4 20:49:02 #endmeeting
