TboneMorning all, I just started with a kolla deployment of designate and everything seemed to have gone well. I noticed however that the mdns service was listening on the public interface which is fine but the bind9 service was listening on the private network interface. bind9 should definitely listen on the public interface as well..07:02
Tbonejust wanted to make sure if anyone else deployed designate via kolla and experienced the same ?07:02

eanderssonTbone there is a variable called dns_interface for designate-mdns to control which interface private vs. public designate should be using16:08
eanderssonAs for bind take a look at this https://github.com/openstack/kolla-ansible/blob/master/ansible/roles/designate/templates/named.conf.j216:09
eandersson> #api_interface: "{{ network_interface }}"16:10
eanderssonIt looks like you need to modify that variable to have bind listen to a public interface16:10

eanderssonmugsie, for the Bad Action error17:49
eanderssonDo you think it's something that would be safe to ignore? as in catching and logging, as opposed to the current exception?17:49
mugsieIt can be an issue, I think17:50
mugsie*think*17:50
mugsieI think it might have something to do with OVO17:50
mugsiebut that is just my gut speaking17:50
eanderssonI see - I can try to dig a big deeper17:50
eanderssonFor sure feels like a race condition17:51
mugsiebut - in theory, we should be able to recover this later anyway, so ignoring it may be fine17:51
eanderssonYea - the lab looks fine, but of course that is a tiny deployment, not sure how this would look in a prod env17:52
mugsieYeah. I am more worried right now about the service status bug that is open17:53
eanderssonAh yea been meaning to look into that one17:53
rfreire<eandersson> mugsie, for the Bad Action error <- I've seen some in Netflix17:54
eanderssonAh yea - the db thing is a thing17:55
eanderssonJust confirmed in my lab17:55

mugsieoh, no way18:41
eanderssonIt's only affecting worker/producer18:42
eanderssonStill trying to figure out exactly why18:42
eanderssonSo this might be more than one issue18:47
eanderssonlet me whipe the status database18:48
eanderssonlol can't delete the entries due to deadlock18:49
rfreire\o/18:50
eanderssonso I think what is happening is that at some point a duplicate entry gets created for the worker/producer18:52
eanderssonwhen that happens the sql query will never succeed, as the value is no longer unique18:52
eanderssonservice_name + hostname should always be unique18:52
eanderssonso probably a schema issue18:53
eanderssonmugsie, you can probably reproduce this by creating a duplicate entry for one of the services18:54
mugsieyeah, that seems legit18:59

eanderssonmugsie, never touched the orm stuff before, you wanna do the patch?19:59
eanderssonWe just need to do something like this I guess https://github.com/openstack/designate/blob/master/designate/storage/impl_sqlalchemy/migrate_repo/versions/082_unique_ns_record.py19:59
eanderssonThis is unfortunately a two year old bug.20:01
eanderssonWe should handle this in code as well.20:02
eanderssonmaybe change find_service_status to find_service_statuses in central, and raise an exception if there are more than one20:03
