#
# == Class: tripleo::profile::base::neutron::server
#
# Neutron server profile for tripleo
#
# === Parameters
#
# [*bootstrap_node*]
#   (Optional) The hostname of the node responsible for bootstrapping tasks
#   Defaults to hiera('bootstrap_nodeid')
#
# [*certificates_specs*]
#   (Optional) The specifications to give to certmonger for the certificate(s)
#   it will create.
#   Example with hiera:
#     apache_certificates_specs:
#       httpd-internal_api:
#         hostname: <overcloud controller fqdn>
#         service_certificate: <service certificate path>
#         service_key: <service key path>
#         principal: "haproxy/<overcloud controller fqdn>"
#   Defaults to hiera('apache_certificate_specs', {}).
#
# [*dvr_enabled*]
#   (Optional) Is dvr enabled, used when no override is passed to
#   l3_ha_override to calculate enabling l3 HA.
#   Defaults to  hiera('neutron::server::router_distributed') or false
#
# [*enable_internal_tls*]
#   (Optional) Whether TLS in the internal network is enabled or not.
#   Defaults to hiera('enable_internal_tls', false)
#
# [*generate_service_certificates*]
#   (Optional) Whether or not certmonger will generate certificates for
#   HAProxy. This could be as many as specified by the $certificates_specs
#   variable.
#   Note that this doesn't configure the certificates in haproxy, it merely
#   creates the certificates.
#   Defaults to hiera('generate_service_certificate', false).
#
# [*l3_ha_override*]
#   (Optional) Override the calculated value for neutron::server::l3_ha
#   by default this is calculated to enable when DVR is not enabled
#   and the number of nodes running neutron api is more than one.
#   Defaults to '' which aligns with the t-h-t default, and means use
#   the calculated value.  Other possible values are 'true' or 'false'
#
# [*l3_nodes*]
#   (Optional) List of nodes running the l3 agent, used when no override
#   is passed to l3_ha_override to calculate enabling l3 HA.
#   Defaults to hiera('neutron_l3_short_node_names') or []
#   (we need to default neutron_l3_short_node_names to an empty list
#   because some neutron backends disable the l3 agent)
#
# [*neutron_network*]
#   (Optional) The network name where the neutron endpoint is listening on.
#   This is set by t-h-t.
#   Defaults to hiera('neutron_api_network', undef)
#
# [*step*]
#   (Optional) The current step in deployment. See tripleo-heat-templates
#   for more details.
#   Defaults to hiera('step')
#
