mixos | hi chlong | 00:18 |
mixos | Does anyone know best way to start barbican-worker with rabbitMQ ? Apparent barbican-worker has to be manually started. | 00:23 |

electrichead | hi tonyb ! We've done _some_ work to get Barbican to be Python3 compliant, but I don't think we're 100% compliant yet | 16:54 |

mixos | Hi, | 17:40 |
mixos | anyone know that barbican can work with rabbitMQ cluster (not local rabbitMQ) ? | 17:40 |
mixos | for orders ? | 17:40 |
mixos | I see a lot of noise. | 17:42 |

redrobot | hi 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 |

mixos | redrobot: hope your important plan is going well without glitch. :- ) | 18:43 |
mixos | Does rackspace use orders ? | 18:43 |
redrobot | mixos not currently, no | 18:44 |
mixos | then how to leverage HSM ? | 18:44 |
redrobot | mixos we're using HSMs for all crypto operations (encrypt, decrypt, etc) | 18:44 |
mixos | ok... using secrets , customers need to bring their own secret payload.. correct ? (please understand dumb question). | 18:46 |
redrobot | mixos correct. for our deployment (without queue or workers) the user provides their own secret data | 18:47 |
mixos | ok... right now.. I have setup 3 barbican nodes + mariaDB+ rabbitMQ.. but I see that barbican does not play nice with rabbitMQ "cluster" | 18:47 |
mixos | I see a lot of these... | 18:48 |

mixos | oslo_messaging._drivers.imple_rabbit is complaining about Dup'ed msgs. | 18:49 |
mixos | Does this mean that I can NOT use rabbit cluster ? | 18:49 |
redrobot | mixos interesting.... but the messages are different? or supposed to be different anyway? | 18:49 |
mixos | I take that the complain is valid. it looks like dup'ed msg. | 18:50 |
mixos | Does this mean that I have to use "LOCAL" rabbitMQ ? not cluster ? | 18:50 |
mixos | like .. each barbican node should have rabbitMQ locally, not clustered ? | 18:51 |
redrobot | mixos the idea is for all API nodes to use the same Rabbit Queue | 18:51 |
redrobot | mixos and the workers as well | 18:51 |
redrobot | mixos we should definitely support clusters. AFAIK there's nothing in Barbican that would prevent that. | 18:52 |
redrobot | mixos that said, I'm not sure what the oslo.messaging support for it is | 18:52 |
mixos | ok... that means... rabbitMQ can't be clustered. but only one rabbitMQ node should be taking messges. | 18:52 |
redrobot | mixos you should be able to use a cluster | 18:52 |
*** gyee has joined #openstack-barbican | 18:53 | |
redrobot | mixos you may have found a bug in either oslo.messaging or Barbican | 18:53 |
mixos | (reading what you said.. and really appreciate your time .) | 18:53 |
mixos | redrobot just a few more questions. | 18:54 |
*** shohel has quit IRC | 18:55 | |
mixos | 1. Does this "barbican-worker" have anything to do with "workers=1" in barbican.conf ? | 18:55 |
mixos | 2. 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 |
mixos | 3. 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 |

*** ccneill has quit IRC | 19:03 | |
mixos | redrobot : Did I break the robot with too many questions. :- ) | 19:04 |
mixos | The reason I want to use queue is ... without queue, I see many orders failing when high volume of orders coming in. | 19:09 |
mixos | Even with the above dup'ed msg errs, all orders going through ok. | 19:09 |
