# == Class: tripleo::profile::pacemaker::rabbitmq_bundle
#
# Containerized RabbitMQ Pacemaker HA profile for tripleo
#
# === Parameters
#
# [*rabbitmq_docker_image*]
# (Optional) The docker image to use for creating the pacemaker bundle
# Defaults to hiera('tripleo::profile::pacemaker::rabbitmq_bundle::rabbitmq_docker_image', undef)
#
# [*rabbitmq_docker_control_port*]
# (Optional) The bundle's pacemaker_remote control port on the host
# Defaults to hiera('tripleo::profile::pacemaker::rabbitmq_bundle::control_port', '3121')
#
# [*bootstrap_node*]
# (Optional) The hostname of the node responsible for bootstrapping tasks
# Defaults to hiera('rabbitmq_short_bootstrap_node_name')
#
# [*erlang_cookie*]
# (Optional) Content of erlang cookie.
# Defaults to hiera('rabbitmq::erlang_cookie').
#
# [*user_ha_queues*]
# (Optional) The number of HA queues in to be configured in rabbitmq
# Defaults to hiera('rabbitmq::nr_ha_queues'), which is usually 0 meaning
# that the queues number will be CEIL(N/2) where N is the number of rabbitmq
# nodes.
#
# [*rabbit_nodes*]
# (Optional) The list of rabbitmq nodes names
# Defaults to hiera('rabbitmq_node_names')
#
# [*step*]
# (Optional) The current step in deployment. See tripleo-heat-templates
