ivvehey, any recommendations on: Could not load neutron_lbaas.drivers.haproxy.namespace_driver.HaproxyNSDriver. followed all guides n did tons of searches. deployed via openstack ansible stable/pike branch20:09
johnsomivve This is a "WARNING" message from neutron, that usually is completely false as it later loads the driver.20:20
johnsomivve If at all possible I recommend you do not use neutron-lbaas and go Octavia native as we are going to deprecate neutron-lbaas soon.20:20
johnsomHowever, if you need that old namespace driver, you will need to stick with neutron-lbaas for now20:22
ivvejohnsom: doesn't seem to work actually, installing it screwed over neutron badly but managed to get that going. im unsure if my heat stack is proper.. after doing some reading it seems that its possible that applying sec groups via heat to the lb port doesn't work20:28
ivvei also seem to get a lot of errors talking to amqp20:29
johnsomhmm, will that old namespace driver relies on the messaging queue heavily, so that could explain issues with it not functioning well.20:30
johnsomModifying the security groups on the LB port should be avoided if you can, as neutron-lbaas will modify those to open the ports defined as "listeners"20:30
openstackgerritMichael Johnson proposed openstack/octavia master: ACTIVE-ACTIVE: Amphora driver updates  https://review.openstack.org/52919120:31
ivvei see20:32
johnsomI can tell you that the neutron-lbaas code is working for the old driver, we have gates that test it and are passing, so it is likely configuration issues that are causing you trouble.20:32
ivvedo you know if octavia is available as a playbook in osa?20:34
johnsomYes it is20:34
johnsomhttps://docs.openstack.org/openstack-ansible-os_octavia/latest/20:34
johnsomhttps://github.com/openstack/openstack-ansible-os_octavia20:35

*** slaweq has joined #openstack-lbaas20:45
ivveis octavia missing any functionality as of now?20:49
*** slaweq has quit IRC20:49
johnsomIt doesn't support third part drivers yet, it only supports the octavia reference driver. Otherwise, no, it's a superset of neutron-lbaas20:50
ivvei see, with horizon panels too? are the images required to support octavia? as there is a guide to it20:52
ivveor is it simply for the standalone service?20:52
johnsomDocs are here: https://docs.openstack.org/developer/octavia/20:52
johnsomHorrion panels are here: https://github.com/openstack/octavia-dashboard20:52
johnsomCLI is here: https://github.com/openstack/python-octaviaclient20:53
johnsomAll are pip installable20:53
johnsomThere is an image required for the service VMs, but there is a script in the diskimage-create directory that will create it for you: https://github.com/openstack/octavia/tree/master/diskimage-create20:54
johnsomThough if you are using OSA it will handle it for you.20:54
ivveas lxc containers is the way to go in osa im guessing thats what the playbook will setup20:56
johnsomYes, for the control plane.  The load balancing service VMs are still nova instances.20:58
ivveoh i see20:58
ivveis there a plan to move them to lxc containers or to keep it that way?20:59
johnsomYes, we would like to use lxc, but we ran into some bugs in the OpenStack implementation for lxd/lxc and lost the developer working on it. It's still on the roadmap, just not there yet20:59
ivvecool21:00
ivvethanks for answering all them questions!21:11
johnsomNo problem, good luck21:11
ivveim guessing ill have to try to get lbaasv2 configured for now :)21:11
johnsomOk21:11
ivveaye i think i got it working but clearly issues with security groups / iptables21:19
*** fyxim_ is now known as fyxim21:21
ivvewhat i did earlier was created a heat OS::Neutron::SecurityGroup and attached it on the loadbalancer vip OS::Neutron::Port (security_groups:)21:21
ivvebut i read that this shouldn't be working?21:22
johnsomI'm not sure when using the old namespace driver. I'm not very familiar with it .21:23
ivvenamespace can curl at least :) (just a simple http test)21:27
*** threestrands has joined #openstack-lbaas21:34
ivveyup it works but obviously has flaws with floating ip and security groups21:35
ivvecurling from the local router namespace on the vip works perfectly21:36
johnsomfloating IPs should work as that is part of our test suite.21:38
ivvethe ip gets allocated in the router but no traffic seems to go to the loadbalancer21:42
ivvechanged the default policies (sec groups)21:43
ivveip addr show on the namespace router does show the floating ip21:47
ivvei can see that the LB is using default sec group so perhaps it still not working even though i allowed all tcp traffic from any cidr21:48
ivveloadbalancer namespace iptables looks fine to me as well21:48
ivveinstance sec groups work as well since curling from the router namespace works and loadbalances correctly as roundrobin (as configured)21:49
ivvewell i think i give up here for today and deliver sad news tomorrow :)21:49
