Puppet module to deploy RabbitMQ bundle for HA
This module is used by tripleo-heat-templates to configure and deploy Kolla-based RabbitMQ containers managed by pacemaker. We use short-lived containers that call pcs via puppet to create the needed pacemaker resources, properties and constraints. Co-Authored-By: Michele Baldessari <michele@acksyn.org> Co-Authored-By: John Eckersberg <jeckersb@redhat.com> Partial-Bug: #1692909 Change-Id: I0722e4a4d4716f477e8304cfa1aadd3eef7c2f31 Depends-On: I44fbd7f89ab22b72e8d3fc0a0e3fe54a9418a60f Depends-On: Ie9b7e7d2a3cec4b121915a17c1e809e4ec950e7f

+# == 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
+# for more details.
+# Defaults to hiera('step')
+#
+# [*pcs_tries*]
+# (Optional) The number of times pcs commands should be retried.
+# Defaults to hiera('pcs_tries', 20)
