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 undef
- rabbitmq_docker_control_port
-
(Optional) The bundle’s pacemaker_remote control port on the host Defaults to 3122
- 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.
- rpc_scheme
-
(Optional) Protocol for oslo messaging rpc backend. Defaults to hiera(‘oslo_messaging_rpc_scheme’).
- rpc_bootstrap_node
-
(Optional) The hostname of the node responsible for bootstrapping tasks when rabbit is configured for rpc messaging backend Defaults to hiera(‘oslo_messaging_rpc_bootstrap_node_name’)
- rpc_nodes
-
(Optional) Array of host(s) for oslo messaging rpc nodes. Defaults to hiera(‘oslo_messaging_rpc_node_names’, []).
- notify_scheme
-
(Optional) oslo messaging notify backend indicator. Defaults to hiera(‘oslo_messaging_notify_scheme’).
- notify_bootstrap_node
-
(Optional) The hostname of the node responsible for bootstrapping tasks when rabbit is configured for rpc messaging backend Defaults to hiera(‘oslo_messaging_notify_bootstrap_node_name’)
- notify_nodes
-
(Optional) Array of host(s) for oslo messaging notify nodes. Defaults to hiera(‘oslo_messaging_notify_node_names’, []).
- enable_internal_tls
-
(Optional) Whether TLS in the internal network is enabled or not. Defaults to hiera(‘enable_internal_tls’, false)
- rabbitmq_extra_policies
-
(Optional) Hash of extra policies for the HA queues Defaults to hiera(‘rabbitmq_extra_policies’, => ‘always’)

-
(Optional) The number of times pcs commands should be retried. Defaults to hiera(‘pcs_tries’, 20)
- step
-
(Optional) The current step in deployment. See tripleo-heat-templates for more details. Defaults to hiera(‘step’)
- container_backend
-
(optional) Container backend to use when creating the bundle Defaults to ‘docker’
- log_driver
-
(optional) Container log driver to use. When set to undef it uses ‘k8s-file’ when container_cli is set to podman and ‘journald’ when it is set to docker. Defaults to undef
- log_file
-
(optional) Container log file to use. Only relevant when log_driver is set to ‘k8s-file’. Defaults to ‘/var/log/containers/stdouts/rabbitmq-bundle.log’
- tls_priorities
-
(optional) Sets PCMK_tls_priorities in /etc/sysconfig/pacemaker when set Defaults to hiera(‘tripleo::pacemaker::tls_priorities’, undef)
- bundle_user
-
(optional) Set the –user= switch to be passed to pcmk Defaults to ‘root’
