# == Class: tripleo::profile::base::memcached
#
# Memcached profile for tripleo
#
# === Parameters
#
# [*enable_internal_memcached_tls*]
#   (Optional) Whether TLS in the internal network is enabled or not for
#   Memcached servers.
#   Defaults to undef
#
# [*certificate_specs*]
#   (Optional) The specifications to give to certmonger for the certificate
#   it will create. Note that the certificate nickname must be 'memcached' in
#   the case of this service.
#   Example with hiera:
#     tripleo::profile::base::memcached::certificate_specs:
#       hostname: <overcloud controller fqdn>
#       service_certificate: <service certificate path>
#       service_key: <service key path>
#       principal: "memcached/<overcloud controller fqdn>"
#   Defaults to {}.
#
# [*step*]
#   (Optional) The current step in deployment. See tripleo-heat-templates
#   for more details.
#   Defaults to hiera('step')
#
