Puppet Class: profile::openstack::base::rabbitmq

Defined in:
modules/profile/manifests/openstack/base/rabbitmq.pp

Summary

Cloud VPS OpenStack RabbitMQ message queue server

Overview

There are two similarly-named params here, '$rabbitmq_setup_nodes' and '$rabbitmq_nodes':

$rabbitmq_nodes is the list of nodes that rabbitmq clients should actually use; it will generally
 consist of wikimediacloud.org service names rather than physical hardware fqdns. These values
 will be baked into unpuppetized Trove VMs and so should be changed as little as possible; changes
 to active rabbit nodes should be made via dns changes to the service fqdns.

$rabbitmq_setup_nodes is a list of fqdns of hosts that are configured by this class but not yet
 in service. It exists to stage new rabbitmq nodes (with firewalls and such) before switching
 traffic over. It should consist of primary fqdns (.wikimedia.org or .wmnet)

Parameters:

  • rabbitmq_service_name (Stdlib::Fqdn) (defaults to: lookup('profile::openstack::base::rabbitmq_service_name'))

    The name that clients use to connect to this server. Usually in the form of rabbitmqNN.DEPLOYMENT.wikimediacloud.org.

  • rabbitmq_own_name (Stdlib::Fqdn) (defaults to: lookup('profile::openstack::base::rabbitmq::rabbitmq_own_name'))

    The name that this node is internally known in the cluster. Usually either rabbitmq_service_name or the node cloud-private address.

  • rabbitmq_nodes (Array[Stdlib::Fqdn]) (defaults to: lookup('profile::openstack::base::rabbitmq_nodes'))
  • rabbitmq_setup_nodes (Array[Stdlib::Fqdn]) (defaults to: lookup('profile::openstack::base::rabbitmq_setup_nodes'))
  • monitor_user (Any) (defaults to: lookup('profile::openstack::base::rabbit_monitor_user'))
  • monitor_password (Any) (defaults to: lookup('profile::openstack::base::rabbit_monitor_pass'))
  • cleanup_password (Any) (defaults to: lookup('profile::openstack::base::rabbit_cleanup_pass'))
  • file_handles (Any) (defaults to: lookup('profile::openstack::base::rabbit_file_handles'))
  • nova_rabbit_user (String) (defaults to: lookup('profile::openstack::base::nova::rabbit_user'))
  • nova_rabbit_password (String) (defaults to: lookup('profile::openstack::base::nova::rabbit_pass'))
  • neutron_rabbit_user (String) (defaults to: lookup('profile::openstack::base::neutron::rabbit_user'))
  • neutron_rabbit_password (String) (defaults to: lookup('profile::openstack::base::neutron::rabbit_pass'))
  • trove_guest_rabbit_user (String) (defaults to: lookup('profile::openstack::base::trove::trove_guest_rabbit_user'))
  • trove_guest_rabbit_pass (String) (defaults to: lookup('profile::openstack::base::trove::trove_guest_rabbit_pass'))
  • heat_rabbit_user (String) (defaults to: lookup('profile::openstack::base::heat::rabbit_user'))
  • heat_rabbit_password (String) (defaults to: lookup('profile::openstack::base::heat::rabbit_pass'))
  • magnum_rabbit_user (String) (defaults to: lookup('profile::openstack::base::magnum::rabbit_user'))
  • magnum_rabbit_password (String) (defaults to: lookup('profile::openstack::base::magnum::rabbit_pass'))
  • rabbit_erlang_cookie (Any) (defaults to: lookup('profile::openstack::base::rabbit_erlang_cookie'))
  • rabbit_cfssl_label (Optional[String]) (defaults to: lookup('profile::openstack::base::rabbitmq::rabbit_cfssl_label', {default_value => undef}))
  • heartbeat_timeout (Integer) (defaults to: lookup('profile::openstack::base::heartbeat_timeout'))
  • version (String) (defaults to: lookup('profile::openstack::base::version'))
  • cloud_private_supernet (Stdlib::IP::Address::V4) (defaults to: lookup('profile::wmcs::cloud_private_subnet::supernet'))
