# == Class: tripleo::profile::base::qdr

# Qpid dispatch router profile for tripleo

# === Parameters
#
# [*qdr_username*]
# Username for the qdrouter daemon
# Defaults to undef
#
# [*qdr_password*]
# Password for the qdrouter daemon
# Defaults to undef
#
# [*qdr_listener_port*]
# Port for the listener (note that we do not use qdr::listener_port
# directly because it requires a string and we have a number.
# Defaults to hiera('tripleo::profile::base::qdr::qdr_listener_port', 5672)
#
# [*qdr_node_names*]
# Set of nodes for qdr mesh deployment setup
# Defaults to hiera('rabbitmq_node_names')
#
# [*step*]
# (Optional) The current step in deployment. See tripleo-heat-templates
# for more details.
# Defaults to hiera('step')
