RabbitMQ is a message broker written in Erlang.
|
||
|
|
It is currently the default provider of message queues in Kolla Ansible
|
||
|
|
deployments.

Passing arguments to RabbitMQ server's Erlang VM
|
||
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
|
|
||
|
|
Erlang programs run in Erlang VM (virtual machine) and use Erlang runtime.
|
||
|
|
Erlang VM can be configured.
|
||
|
|
|
||
|
|
Kolla Ansible makes it possible to pass arguments to the Erlang VM via the
|
||
|
|
usage of ``rabbitmq_server_additional_erl_args`` variable. The contents of it
|
||
|
|
are appended to ``RABBITMQ_SERVER_ADDITIONAL_ERL_ARGS`` environment variable
|
||
|
|
passed to RabbitMQ server startup script. Kolla Ansible already configures
|
||
|
|
RabbitMQ server for IPv6 (if necessary). Any argument can be passed there as
|
||
|
|
documented in https://www.rabbitmq.com/runtime.html
