 #
 # === 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', {}).
+#
+# [*enable_internal_tls*]
+#   (Optional) Whether TLS in the internal network is enabled or not.
+#   Defaults to hiera('enable_internal_tls', false)
+#
+# [*ec2_api_network*]
+#   (Optional) The network name where the ec2api endpoint is listening on.
+#   This is set by t-h-t.
+#   Defaults to hiera('ec2_api_network', undef)
+#
 # [*step*]
 #   (Optional) The current step in deployment. See tripleo-heat-templates
 #   for more details.
 #   Defaults to hiera('step')
 #
+# [*ec2_api_tls_proxy_bind_ip*]
+#   IP on which the TLS proxy will listen on. Required only used if
+#   enable_internal_tls is set.
+#   Defaults to undef
+#
+# [*ec2_api_tls_proxy_fqdn*]
+#   fqdn on which the tls proxy will listen on. Required only used if
+#   enable_internal_tls is set.
+#   Defaults to undef
+#
+# [*ec2_api_tls_proxy_port*]
+#   port on which the tls proxy will listen on. Only used if
+#   enable_internal_tls is set.
+#   Defaults to 8788
