leitan_Hi guys, quick question, im trying to work with SSL enabled rabbitmq, without SSL everything works fine, but when converted my deploy to SSL, and moved the rabbitmq listen port from 5672 to 5671, now im getting from nova api that cannot connect to "myrabbits:5672" BUT the transport URL says 5671 and also the rabbit_port on the oslo_messaging_rabbit section says that, what am i missing here ?17:21

kgiustileitan_: setting the port in the transport_url and rabbit_port should be all that you need to do.  What version oslo.messaging btw?17:44

leitan_kgiusti: python-oslo-messaging-5.17.1-2.el7ost.noarch17:50
*** nicolasbock has joined #openstack-oslo17:50
leitan_and something weird is, if i comment all the transport_url , the nova api is still getting the rabbit hosts list from somewthere, with the defalt 5672 also17:51
leitan_and i dont have the "rabbit_hosts" key on the oslo_messaging_rabbit section17:53
kgiustileitan_: the only thing that comes to mind is if - somewhere - the port _isn't_ specified.  If no port is provided the driver will default to 5672.17:55
leitan_kgiusti: though the same ... but if i have the port on the transport_url and also the rabbit_port ... im wondering why is defaulting ?17:56
kgiustileitan_: since the port is explicitly specified then it shouldn't default.   Did any of the nova code hardcode a port#?17:59
leitan_kgiusti: nope, i greped the whole nova installed code, no 5672 anywhere18:00
kgiustileitan_: if you're feeling brave, modify the Connection class in oslo_messaging/_drivers/impl_rabbit.py around line 540 and log the value of the self._url field.  Extra points to throw an exception if port != 567118:02
kgiustileitan_: but otherwise it sounds like you've done all the correct configuration settings.18:02
leitan_kgiusti: brave is my second name, going to log it right now18:03
kgiusti:)18:03
leitan_kgiusti: and yes ... self._url  amqp://nova:46IxYtLR744ADVlNBpAa@192.168.90.11:5672//;amqp://nova:46IxYtLR744ADVlNBpAa@192.168.90.10:5672//;amqp://nova:46IxYtLR744ADVlNBpAa@192.168.90.12:5672//18:09
leitan_WTF hahaha18:09
kgiusti!18:09
leitan_kgiusti: transport_url = rabbit://nova:46IxYtLR744ADVlNBpAa@192.168.90.10:5671,nova:46IxYtLR744ADVlNBpAa@192.168.90.11:5671,nova:46IxYtLR744ADVlNBpAa@192.168.90.12:5671/?ssl=118:09

*** tesseract has quit IRC18:15
leitan_kgiusti: well i guess i know what it is18:15
kgiustileitan_: a bug?18:15
leitan_kgiusti: since this is ocata, and you need to create a CELL18:16
leitan_you need to specify a transport url for the CELL18:16
leitan_well, in there is still the 567218:16
leitan_for the cell18:17
leitan_and that is cached forever18:17
kgiustileitan_: O_o18:17
leitan_you have to update the transport url for the cell ... and restart the nova-api18:18
kgiustiyep - that would do it18:19

mriedemdims: can you take a look at this? https://bugs.launchpad.net/oslo.messaging/+bug/171791520:02
openstackLaunchpad bug 1717915 in oslo.messaging "nova services and transport_url, cannot connect to vhost if specified" [Undecided,New]20:02
dimsmriedem : ack looking20:03
mriedemlooks like the virtual_host is getting applied to all transports20:20
mriedembecause of how the parsing is happening20:20

openstackLaunchpad bug 1717915 in oslo.messaging "nova services and transport_url, cannot connect to vhost if specified" [Undecided,New]20:20
kgiustimriedem: ping ^^20:30
mriedemyup20:31
kgiustimriedem: the definition of the TransportURL allow multiple (user:pass@host:port) entries in the transport URL, but they do share the same vhost20:31
kgiustithe rabbit driver assumes all hosts are equivalent, picks one to connect to.20:32
mriedemas long as the vhost is in the last url20:32
kgiustiright - is the parsing wrong?20:32
mriedemno, not if you look at the code and recreate it :)20:33
mriedemthe transport_url docs should probably be updated for clustered transports formatting of the option value20:33
kgiustihttps://docs.openstack.org/oslo.messaging/latest/reference/transport.html20:33
mriedemok i mean the actual docs that show up in a sample conf20:34
mriedemlike in https://docs.openstack.org/nova/latest/configuration/sample-config.html20:35
mriedemall you get is this:20:35
mriedem # A URL representing the messaging driver to use and its full configuration. # (string value) #transport_url = <None>20:35
kgiustimriedem: oh crap - yes that.20:35
mriedemas for why this is failing with nova, i'm not sure20:35
kgiustimriedem: fails for both the transport_url config and the old rabbit_hosts config?20:37
dims"<TransportURL transport='rabbit', virtual_host='nova_vhost', hosts=[<TransportHost hostname='192.168.110.1', port=5672, username='nova', password='nova_pass'>, <TransportHost hostname='192.168.110.2', port=5672, username='nova', password='nova_pass'>, <TransportHost hostname='192.168.110.3', port=5672, username='nova', password='nova_pass'>]>"20:40
mriedemkgiusti: not sure, it could be a cells v2 thing in nova in ocata20:40
dimskgiusti : mriedem : looks like the virtual_host is for all of them20:40
kgiustidims: +120:40
dimswe need to make them specific to each TransportHost to support this20:41
dims"rabbit://nova:nova_pass@192.168.110.1:5672,nova:nova_pass@192.168.110.2:5672,nova:nova_pass@192.168.110.3:5672/nova_vhost"20:41
dimshmm, i take that back20:41
mriedemi'm told owalsh from tripleo will know20:42
mriedembut he's not around right now20:42
mriedemtripleo uses clustered rabbit in rhosp20:42
mriedemso they should be able to clarify how to set this up for cells v220:42
kgiustidims: the old rabbit_vhost config param... think that worked the same way (one vhost for all hosts addresses)20:42
dimsright, that's what i meant about taking it back20:42
dimskgiusti : i am looking at where rabbit_virtual_host is used20:43
