Tacker conductor
================
Tacker conductor is a component which is used to communicate with other
components via message RPC. In the conductor, the RPC server sides can
access the tacker base on behalf of them.
To start
==============
Tacker conductor can be started via python console entry script
'tacker-conductor':
.. code-block:: console
tacker-conductor --config-file /etc/tacker/tacker.conf
..
we can easily start many tacker-conductor instances with different 'host' value
in the configuration file:
.. code-block:: console
test@ubuntu64:~/devstack$ grep 'host = secondinstance' /etc/tacker/tacker2.conf
host = secondinstance
..
and then start the second instance:
.. code-block:: console
tacker-conductor --config-file /etc/tacker/tacker2.conf
..
Rabbitmq queues
===============
Tacker conductor is listening on three queues:
.. code-block:: console
test@ubuntu64:~/tacker$ sudo rabbitmqctl list_queues | grep CONDUCTOR
TACKER_CONDUCTOR 0
TACKER_CONDUCTOR.ubuntu64 0
TACKER_CONDUCTOR_fanout_0ea005c0b666488485a7b3689eb70168 0
..
But only TACKER_CONDUCTOR queue without host suffix is used.
