johnsomYes16:57
Alex_Stafjohnsom, yep glad to hear :)16:57
Alex_Stafjohnsom, yeah I agree than neutron lbaas is less interesting . BUT, I think we should see if it is repeated in openstack loadbalancer member show/list16:59
johnsomThe status is reported on members in the OSC client.17:00
Alex_Stafjohnsom, awesome17:03

sanfernhi johnsom18:24
johnsomsanfern Hi18:25
sanferni feel we need to normalized the tables of L3 AA18:25
johnsomivve You can, but it is not recommended as the LB manages that SG applied to the ports18:25
sanfernnow i am assuming one peer only support18:26
johnsomI thought we did that here: https://review.openstack.org/#/c/528850/18:26
*** AlexeyAbashkin has quit IRC18:26
ivveok, just getting no route to host now.. no clue why. all routes look fine to me18:26
ivvevia the FIP18:26
ivveotherwise stuff works18:26
johnsomOh, are you discussing the concern of multiple vips per amphora?18:27
sanfernyes18:27
johnsomivve If you are using DVR it might be a DVR related bug18:27
sanfernmultiple tor switch18:27
ivveoh a bug?18:27
sanfernone for v6 and one for v418:27
ivvei am using dvr18:27
ivveso its known18:27
johnsomsanfern, if we can leave the design open to support it in the future cool.  If it's really causing complications we can consider changing it.18:27
ivvei guess i could turn off ha on the switch to test18:28
johnsomivve DVR has had a number of issues with FLIPs.18:28
ivvejohnsom: checkbox!18:28
ivvebut regarding sec groups18:28
ivvethe port is getting the default sec group18:28
ivve(i am using heat)18:28
*** aojea has quit IRC18:28
johnsomivve You may need to rebuild the flip to get it resolved after disabling DVR18:29
sanfernjohnsom, i am considering one peer now but future we can drop L3_BGP_peer_reg table18:29
ivveshould i not try to assign a secgroup to the vip?18:29
johnsomivve each VIP should get a unique security group....  If it's an AAP port, check the base port SG18:30
ivveaye ill rebuild the hole stack18:30
ivvejohnsom: cool!18:30
johnsomsanfern Ah, I see.  So, you are proposing having a speaker only talk to one peer (tor)?18:31
sanfernyes for this release18:32
johnsomsanfern I thought Janson wanted to have a centralized speaker that did all of the advertisements in the future.18:32
johnsomI am all for simplifying and incremental improvement, we just need to make sure we have an upgrade strategy/plan of how we can get to where Jason want's to go with it.18:33
sanfernjohnsom, we will have one peer i.e. TOR switch, speaker will be running in all the amps18:33
*** gcheresh has joined #openstack-lbaas18:34
sanfernDATA_MODEL needs to be normalized we will be good, jason requirements changes every meeting ;)18:34
johnsomHa, ok18:35
johnsomWell, no harm in putting up a proposed patch18:35
sanfernok18:35
*** salmankhan has quit IRC18:35
johnsomMaybe add a comment that describes "why" to help reviewers18:35
*** aojea has joined #openstack-lbaas18:35
*** rstarmer has joined #openstack-lbaas18:36
sanfernjohnsom, I agree, Will add that.18:40
*** aojea has quit IRC18:41
ivvejohnsom: didn't do it, router was created with "ha: false" but no cigar. no route to host18:53
johnsomHmm, ok, that is odd then18:54
sanfernjohnsom, in delete_distributor task i am just maring distributor prov_status to deleted. I am not removing speaker or peer entries18:54
ivvethere is "distributed: false" as well, could try that18:54
johnsomsanfern that is good.  We should clean those up with housekeeping per the deleted retention policy in the config18:55
sanfernok we need to write housekeeping flow to delete tables18:55
johnsomivve Ah, yes, they are different. DVR is distributed, HA is just HA routers with keepalived18:55
johnsomsanfern there is an existing flow, it probably just needs extended18:56
sanfernok18:56
ivvetesting...18:56
ivvethats wierd18:56
ivveCreate Failed18:57
ivveResource Create Failed: Badrequest: Resources.Router: Unrecognized Attribute(S)18:57
ivve'Distributed' Neutron Server Returns Reques18:57
ivve:)18:57
*** jniesz has joined #openstack-lbaas18:57
ivvesomeone really doesn't want me doing this lbaas thing18:57
*** atoth has quit IRC18:58
johnsomWell, that doesn't have anything to do with lbaas....18:58
johnsomWe are just victims of other project bugs.... grin18:58
ivvetrue dat19:01
*** atoth has joined #openstack-lbaas19:04
*** gcheresh has quit IRC19:11
ivvejohnsom: well i was under the impression i was using dvr... but neutron.conf in server says false on both settings... l3_ha says true though19:13
ivvehaha. any thoughts? :D19:13
johnsomUmm, I don't know why it would say L3 HA but not be enabled in the config.  That is a mystery. But, if distributed is disabled when you do show router for the VIP router, it's not DVR related....19:14
johnsomOn devstack, it doesn't setup route to the private network from the host anymore, but I assume that is not your setup....19:15
sanfernjohnsom, http://paste.openstack.org/show/P7smyrv1T9FV3IH4IMv1/ can we have dynamic j2 template, like neig19:16
sanfernmore neighbors entry means more peer_ip's19:16
jnieszthat would require another python process running19:17
jnieszwould prefer not to use sub process19:17
*** atoth has quit IRC19:17
openstackgerritOpenStack Release Bot proposed openstack/python-octaviaclient master: Update reno for stable/queens  https://review.openstack.org/53545619:18
johnsomjniesz Not sure I follow.19:19
ivvejohnsom: nah its a 7 node setup with 3 controllers where all 7 are compute as well as ceph nodes19:20
jnieszprocess flask-api {19:20
jniesz                run /path/to/python /path/to/app.py;19:20
jniesz        }19:20
jnieszthat is basically running a separate python process to import stuff into exabgp19:20
johnsomsanfern Sure, not a problem. This is how we configure keepalived, the neighbor blocks are just in a for loop in jina19:20
sanfernjniesz, ignore run19:20
johnsomjniesz Why is that needed?19:20
jnieszi am saying it is not19:20
johnsomAh, ok19:21
johnsomYeah, I can't think why it would be needed either19:21
jnieszi think sanfern was just showing two neighbors19:21
sanfernI wanted to make multiple entry of neighbor in j219:21
jnieszoption19:21
jnieszthe case we want to handle is multiple neighbors19:21
jnieszsome people might need to peer to more than one19:22
ivvejohnsom: so the lbaas namespace has a default route (to private subnet)19:22
johnsomsanfern https://github.com/openstack/octavia/blob/master/octavia/common/jinja/haproxy/templates/macros.j2#L24819:22
ivvefrom that namespace i can reach both the provider router as well as the private subnet router19:22
ivvesnat is enabled on all routers19:23
jnieszusing for loop seems like right way to handle multiple neighbors19:23
johnsomivve Default route should be to the VIP network.  There also might be policy base routing rules. Not sure on that old driver19:23
ivvenever thought about that... :P19:23
sanfernjohnsom, this is how i did it for multiple vip to dummy0.cfg file19:23
johnsomsanfern +119:24
ivveits the rootwrap that sets it19:24
ivve(the gw)19:24
jnieszjohnson: one thing I was discussing with sanfern is removing the speaker and bgp peer tables19:25
jnieszsince that will now be coming from config file19:25
jnieszi think it only makes sense to keep the tables, if we also build the cli / api's for the administrator to define those19:26
johnsomjniesz I think they should stay as you want failover rebuilds to use the stored values and not the "new" values that may be in the config.19:26
sanfernhttps://review.openstack.org/#/c/524722/33/octavia/db/models.py - DistributorL3BGPPeerRegistration19:26
ivvejohnsom: ah it is.. i read flip19:26
sanfernDo we need this table - DistributorL3BGPPeerRegistration - one to many relationship19:27
ivveso default route on lbaas netns is correct, everything is reachable there all routers. all the instances can reach those routers as well19:27
jnieszthe reason I created that table was to associate peers to one or more bgp speakers19:28
jnieszthat will be more relevant when we have dedicated distributors19:28
johnsomRight19:28
jnieszfrom a modeling perspective you register bgp peers to a bgp speaker19:29
jnieszand bgp speaker has some config info19:29
jnieszand bgp peers = neighbor19:29
johnsomIf we have a upgrade/migration path for that in the future when we do a "dedicated distributor for L3" I am fine with dropping that now. But we should balance if it's just easier to leave it with single records for now vs. dropping it19:29
sanfernwe will have speaker table, peer table19:30
jnieszit makes sense to keep, right now it is 1:119:31
johnsomFYI, I have released python-octaviaclient 1.4.0 which will be our Queens OSC plugin release.19:31
jnieszactually if there are two neighbors it would be 1:2119:31
