electricheadhi tonyb !  We've done _some_ work to get Barbican to be Python3 compliant, but I don't think we're 100% compliant yet16:54

mixosHi,17:40
mixosanyone know that barbican can work with rabbitMQ cluster (not local rabbitMQ) ?17:40
mixosfor orders ?17:40
mixosI see a lot of noise.17:42

redrobothi mixos !  I'm not entirely sure if Barbican does work with RabbitMQ Clusters...  we're currently not using queues in the Rackspace deployment.18:22

mixosredrobot: hope your important plan is going well without glitch. :- )18:43
mixosDoes rackspace use orders ?18:43
redrobotmixos not currently, no18:44
mixosthen how to leverage HSM ?18:44
redrobotmixos we're using HSMs for all crypto operations (encrypt, decrypt, etc)18:44
mixosok... using secrets , customers need to bring their own secret payload.. correct ? (please understand dumb question).18:46
redrobotmixos correct.  for our deployment (without queue or workers) the user provides their own secret data18:47
mixosok... right now.. I have setup 3 barbican nodes + mariaDB+ rabbitMQ.. but I see that barbican does not play nice with rabbitMQ "cluster"18:47
mixosI see a lot of these...18:48

mixososlo_messaging._drivers.imple_rabbit is complaining about Dup'ed msgs.18:49
mixosDoes this mean that I can NOT use rabbit cluster ?18:49
redrobotmixos interesting.... but the messages are different?  or supposed to be different anyway?18:49
mixosI take that the complain is valid. it looks like dup'ed msg.18:50
mixosDoes this mean that I have to use "LOCAL" rabbitMQ ? not cluster ?18:50
mixoslike .. each barbican node should have rabbitMQ locally, not clustered ?18:51
redrobotmixos the idea is for all API nodes to use the same Rabbit Queue18:51
redrobotmixos and the workers as well18:51
redrobotmixos we should definitely support clusters.   AFAIK there's nothing in Barbican that would prevent that.18:52
redrobotmixos that said, I'm not sure what the oslo.messaging support for it is18:52
mixosok... that means... rabbitMQ can't be clustered. but only one rabbitMQ node should be taking messges.18:52
redrobotmixos you should be able to use a cluster18:52
*** gyee has joined #openstack-barbican18:53
redrobotmixos you may have found a bug in either oslo.messaging or Barbican18:53
mixos(reading what you said.. and really appreciate your time .)18:53
mixosredrobot just a few more questions.18:54
*** shohel has quit IRC18:55
mixos1. Does this "barbican-worker" have anything to do with "workers=1" in barbican.conf ?18:55
mixos2. what would be good number for this barbican-worker (barbican.queue.server) ?18:55
mixos    (one per a node vs. multiple per node based on number CPUs on the node).18:55
mixos3. Is there particular reason why orders not being used ? If you could briefly explain why, I would appreciate it.18:56
mixos#3. john already answered.18:57
mixos#1, john didn't see any relevance between barbican-worker and workers=1 in barbican.conf.18:58

mixosredrobot : Did I break the robot with too many questions. :-  )19:04
mixosThe reason I want to use queue is ... without queue, I see many orders failing when high volume of orders coming in.19:09
mixosEven with the above dup'ed msg errs, all orders going through ok.19:09
