rm_worknot sure how to assert that a log function was called :/00:11
*** slaweq has joined #openstack-lbaas00:12
johnsomWouldn't it just be asserting that the field is null after the call throws?00:12
johnsomYeah, ok, that is a bit lame.  You can ignore if you want.00:14
rm_workeh, i made a test that SHOULD test that, and at least ensures that it doesn't *break* if the field isn't set00:15

bzhaojohnsom, ping, hi sir.. I had updated the use case of UDP loadbalncer, is that make sence for you? And can I make it forward? Thanks. Link: https://storyboard.openstack.org/#!/story/165709102:18
*** bbbbzhao_ has joined #openstack-lbaas02:24
rm_workyeah we really just need to pick a thing to use as the actual loadbalancer, since haproxy doesn't do it02:25
rm_worki think we were looking at enabling LVS for active-active, so we could make a UDP driver for that02:25

rm_workwoo, some landing02:32
*** slaweq has quit IRC02:38
bzhaorm_work, thannks for the feedback, that means you will implement a LVS driver or something? How about a simple LVS driver for other deployment types(ACTIVE/STANDBY  SINGLE)?02:41
bzhaorm_work, use the ipvsadm directly in the haproxy namespace?02:42
rm_worki mean, if we have LVS stuff created for the active-active case, it will be much easier to develop a driver using it for the other cases02:49
rm_workand it's something we can look into02:49
rm_worki'd love to see a second driver just so we can be sure the interface for that layer is done correctly02:49
rm_worksince right now there could be things that are too haproxy focused02:49
*** slaweq has joined #openstack-lbaas02:49
rm_workessentially yes02:49
bzhaorm_work, thanks. The intent is that we need focus on the UDP driver(maybe not LVS) in ACTIVE/ACTICE case now, then apply on other cases, in the end, we can expose the API for UDP?02:56
bzhaorm_work, could I take deep into the ACTIVE/ACTIVE cases and look forward a possible way to make it work? POC code or something?02:59
rm_workthere's some code up02:59
rm_workif you can talk to johnsom or xgerman_ tomorrow they know much more02:59
bzhaorm_work, OK, thanks03:00
bzhaoI will have a look. :)03:00
johnsombzhao: I think for UDP we should start with standalone and/or active standby.  Active active is not there yet03:02
*** armax has quit IRC03:03
bzhaojohnsom, woow, hi. Thanks for clear. The main idea is which way to bring UDP to octavia. 1. another LVS driver 2. involve some LVS function into service VM namespace and work with haproxy together..03:05
johnsomYeah, I think ideally we would do the second, run LVS and haproxy together.03:06
*** yamamoto has joined #openstack-lbaas03:08
bzhaojohnsom, yeah, for point 1, it is hard to meet the current data model. But the second would work. So the next step, may i update the spec and waiting for your review, and prepare the POC code then03:08
johnsombzhao: I have not yet read the story update, but have you determined LVS can meet your needs?03:08
bzhaojohnsom, I think yes. Do you want to propose other drivers which support UDP in the plan? such as nginx staff?03:09
bzhaojohnsom, if true. That's OK. I could change.03:10
johnsombzhao: I am fine with LVS.  Nginx is probably a bigger piece of work and has other limitations03:10
bzhaojohnsom, Yeah. :). Then could I make the feature forward?03:13
bzhaojohnsom, spec/code03:14
johnsomIf LVS will work for you I use that.03:16
johnsombzhao: yeah, start a spec.  I think it would be reasonably straight forward03:16
johnsomPlease note, most of us are working on other features in queens, so you may need to do most of the development work.03:17
bzhaojohnsom, Thanks very much. I will update the whole spec about this. And will ready soon.03:17
bzhaojohnsom, That's OK. Resource limitation. It's my great honor to contribute octavia.03:19

xgerman_bzhao:  look at https://review.openstack.org/#/c/499807/ and https://review.openstack.org/#/c/505770/ as a starting point03:49
xgerman_(also reviews appreciated)03:49
bzhaoxgerman_, thanks, german. I had discoverd the mentioned patch. will take a look.03:51
xgerman_y.w. also the plan is not to use ipvsadm directly but leverage our keepalived work to push configuration so keepalived will manage lvs for us03:53
xgerman_which you will likely need, too, so you can have healthchecks on the members03:53
bzhaoYeah. I know. eh.. I don't realize it can do like this.03:56
bzhaoI will test it. If I can help to do some work, welcome. :)03:56
xgerman_yep, I am following roughly https://www.tqhosting.com/kb/563/How-to-set-up-LVS-TUN-with-ipvsadm-and-keepalived-on-Ubuntu-1604.html03:57
xgerman_but we need IPIP protocol supported in neutron sec groups again (they have a regression bug)03:58
bzhaoThanks very much for share.03:58
xgerman_yeah, feel free to add code - happy to review but this is the rough outline of the plan03:58
bzhaoxgerman_, thanks for this. It's very clear now. I will take part in Octavia work team for this.04:00
xgerman_awesome ;-)04:00
bzhaoThank you, german. You give so much help to me04:01
johnsomI don’t think the udp work will use the tun or ipnip04:02
*** slaweq has quit IRC04:02
xgerman_yeah, but should use keepalived for healthchecks…04:02
johnsomIt should be simpler than that04:02
xgerman_sure you can just hide behind the fact that delivery is nor guaranteed04:03
xgerman_but otherwise I don’t see how you can fudge healthchecks especially complex ones on different ports04:04
*** slaweq has joined #openstack-lbaas04:05
bzhaoOriginaly, I use ipvsadm to deploy the UDP loadbalncer function directly into the haproxy namespace. They works for UDP Functionality. For ACTIVE/STANDBY case, we also need the keepalive to check if the backend servers are alive. I just stand on this view, because we need to use keepalive for healthchecks. Sorry, not understood what the issue is.04:13

*** bbbbzhao_ has quit IRC04:53
*** eN_Guruprasad_Rn has joined #openstack-lbaas05:10
rm_workbzhao: so are you thinking we just ... *extend* the existing HAProxy driver to be "HAProxy/LVS", where it does everything as usual for TCP but for UDP delegates to LVS?05:11
rm_workinstead of writing a separate driver specifically for LVS where it does any type of loadbalancing?05:12
rm_work(wherein we'd probably need Flavors working so we can do a Flavor that supports UDP)05:12
rm_workI guess maybe the first option (extending the existing haproxy driver) might be the best05:12
*** slaweq has quit IRC05:18
bzhaorm_work, Yeah, I think we get the some staff for the first option. As current data model is difficult for LVS.At first I wanted to introduce a new LVSdriver, but it was impossible to change the data model comprehensively.So it makes me feel like it's useless for introducing a new LVS driver. So I consider Haproxy and LVS working together05:19
*** slaweq has joined #openstack-lbaas05:19
bzhaorm_work, oh sorry, the first sentence change s/some/same05:22
bzhaoThe flavor work like l3 flavors in Neutorn?05:23
rm_worki think so?05:25
rm_worki'm not sure how those work05:25
rm_workbut, i think it SHOULD be possible to do what you need with LVS as a driver05:25
rm_workif not, then we have a problem with our model05:26
rm_worki might poke at it tomorrow if i find a minute05:26
*** eN_Guruprasad_Rn has quit IRC05:27
*** eN_Guruprasad_Rn has joined #openstack-lbaas05:27
bzhaoThank you. And I just test with the simple case in singleton mode. I use ipvsadm into haproxy namespace, can it just provide UDP function, I found it works as wish, but for other tests, such health check, like german said, there maybe some issues I'm not realized05:29
bzhaoI mean haproxy LVS work together.05:31
bzhaoI think it is better to introduce a new driver. But it is hard to let the whole workflow work well, i think.05:33
bzhaocurrent05:33
rm_workit really should work05:34
rm_workif it doesn't work -- that means something is wrong with our models, and we need to fix it05:34
rm_workso, please start assuming that it SHOULD work, and if something is difficult, then it needs to be fixed in Octavia05:34
bzhaoOK, I think I can take the responsibility. :)05:35
bzhaoThank you rmwork05:36
rm_worknp05:36
rm_workfor most of us, this is very late at night (like 22:30), but i think nmagnezi will be up soon maybe :P05:36
rm_workthough soon i'll be on a schedule closer to yours I think05:37
rm_workso maybe in a couple weeks (after the Sydney summit) I can help you more05:37
bzhaoThank you very much. :). Have a good rest. And thanks to list so many useful details.05:38

johnsomIt is on revision 3 and the title is currently incorrect, but we can keep commenting20:04
johnsomOtherwise I have been working on zuul v3 issues, fixing gate breakage (cryptography 2.1), and working around the instance failures at OVH for the gate jobs.20:05
johnsomI have some back ports to do and some more zuul v3 work on the stable branches.20:06
johnsomWe also need to get a scenario gate or two setup for our tempest plugin work.  I may work on that if rm_work isn't able to start that.20:06
johnsomAny other progress reports?20:07
*** gcheresh has quit IRC20:07
johnsomThis dashboard patch could use some core attention too: https://review.openstack.org/51308620:07
johnsomAnd this bug with child object provisioning status:20:08

johnsomAny other bugs to discuss?20:09
jnieszjohnsom: any update regarding Fix allowed_address_pairs network driver to be more tolerant to failure20:09
johnsomjniesz Just that I haven't got back around to work on that20:09
jnieszok, and was the last one related to the issue I raised or is that separate?20:09
johnsomjniesz It was related to the issues you were seeing20:10
johnsomSo, half the battle20:11
johnsomgrin20:11
jniesz: )20:11
johnsomOk, if there aren't any other progress reports/bugs to discuss, I will move on to the next topic.20:12
johnsom#topic UDP load balancing20:12
*** openstack changes topic to "UDP load balancing (Meeting topic: Octavia)"20:12
johnsomWe have an open RFE that has some use case data now:20:13
johnsom#link https://storyboard.openstack.org/#!/story/165709120:13
johnsomFeel free to comment on this RFE story.20:13
johnsomI think the next step is a spec for this.20:13
johnsomMy expectation is an initial implementation can be done with LVS sideloaded in our existing amphora image, with the amphora agent updated to include support for configuring it when a UDP listener comes in.20:15
johnsomKind of a keep it simple approach.20:16
jnieszI think UDP option makes sense, and it is something I would like to implement with L3 distributor20:16
johnsomYeah, that can certainly be a follow on step.20:16
jnieszImportant thing is that spec allows for different implementations of UDP LB20:17
johnsomInitially I'm thinking we should just do standalone, maybe atc/stdby to get the base stuff, API etc. worked out.20:17
johnsomYep.  Please help review to make sure we don't make a mistake20:17
jnieszyes, I can review spec when it is posted20:18
johnsomAny other discussion on this?20:18
xgerman_we should be careful not to duplicate work with ACTIVE-ACTIVE LVS20:19
xgerman_also I think we will need keepalived to manage the health of the UDP members…20:19
johnsomYeah, I think it's 100% different, so really should not overlap20:19
xgerman_I think it overlaps — for instance you would use the same dib element20:20
johnsomThere isn't even a spec for act/act LVS yet, so not a lot there anyway20:20
johnsomI'm not sure we need a DIB element for UDP.  The existing keepalived element should cover everything for UDP20:21
xgerman_we will need ipvsadm on the amp to get sdiagnostic info20:21
xgerman_and debug20:21
johnsomMaybe to get stats20:22
xgerman_yep20:22
johnsomWe will see.20:22
johnsomAnything else?20:23
*** gcheresh has joined #openstack-lbaas20:23
johnsomCool, I think we have a path forward and someone willing to work on it.20:23
johnsomI guess I should say, able to work on it...  So much stuff we could do, just prioritizing...20:24

xgerman_rm_work I will put trust in you to send me some from Sydney20:25
johnsomKendall will try to find rm_work to give them to.20:25
johnsomIf you are at the summit you can catch rm_work to get one.  Otherwise we will figure out how to get them to Dublin for the next PTG20:26
rm_workderp20:26
rm_workdisconnected from IRC and didn't notice >_>20:26
johnsomWell, a bit of scroll  back then....20:27

xgerman_https://www.irccloud.com/pastebin/2YTWYjPa/20:33
Alex_Stafrm_work, any ETA for the plugin patch merge? Tomorrow I have a meeting with dmellado so I hope I will have progress20:33
xgerman_johnsom I leave you with this. I think our Octavia API has issues or I am using it wrong20:34
xgerman_afk for a bit20:34
johnsomYeah, there are a few bugs in the proxy patch.  I posted three on that patch today20:36
rm_workAlex_Staf: the tempest plugin patch?20:36
johnsomAfter hacking through those I was able to get a basic LB running.20:36
rm_workAlex_Staf: i'm looking at some bugs today that johnsom is claiming are there20:36
Alex_Stafrm_work, yes20:36
rm_worki'm hoping we can merge it soon after20:37

nmagnezijohnsom, I forgot about the dst shift :( sorry to miss the weekly meeting. I was actually waiting to join.20:39

johnsomnmagnezi Ah, it shifts for us next week, but the meeting is booked in UTC time so will always be 20:00 UTC20:40

nmagneziAlex_Staf_, i suspect you missed the meeting for the same reason :D20:42
nmagnezirm_work, sorry I didn't get to your AZ patch. we have a crazy week and we *really* try to finalize some Octavia TripleO related stuff20:43
nmagnezirm_work, are there any RHEL specific inputs you need from me?20:43

johnsomJust a reminder, we have a number of zuul v3 related patches in flight: https://etherpad.openstack.org/p/octavia-zuulv3-patches22:11
johnsomI have updated some of those so they should make it through the gates in about an hour.22:11
johnsomThat should be it for phase 1.  Phase 2 would be native playbooks.  I will probably let the dust settle a bit before looking at that.22:12
johnsomBut phase 1 will get us running the right jobs in the right branches22:13

xgerman_https://www.irccloud.com/pastebin/4mCU92Jh/22:35
xgerman_so I would expect when filtering on the id to get only one value back from Ocravia22:36
johnsomLooks like the URL is still wrong (one of the three bugs I noted on that patch today) and I don't think you can pass in filters in the body.  At least our API docs don't show that you can.22:38
johnsomI mean, a body on a get call is *odd*22:38
