[openstack-dev] [kolla-ansible] Configure OpenStack services to use Rabbit HA queues

[v***@oracle.com]

Hi,

is there a reason we don't configure services for rabbitmq ha queues
like it is suggested in [0] ?
Rabbitmq itself has ha policy 'on' via one of its templates.

Thanks,
Vladislav Belogrudov

Hi vladispay,

I guess you are talking rabbit_ha_queues options. It is already marked as
deprecated[0].

cfg.BoolOpt('rabbit_ha_queues',
default=False,
deprecated_group='DEFAULT',
help='Try to use HA queues in RabbitMQ (x-ha-policy: all). '
'If you change this option, you must wipe the RabbitMQ '
'database. In RabbitMQ 3.0, queue mirroring is no longer '
'controlled by the x-ha-policy argument when declaring a '
'queue. If you just want to make sure that all queues
(except '
'those with auto-generated names) are mirrored across all '
'nodes, run: '
"""\"rabbitmqctl set_policy HA '^(?!amq\.).*' """
"""'{"ha-mode": "all"}' \""""),

In kolla, we configure a global ha-mode policy through its definition.json
file in rabbitmq, please check[1]
