parameters:
  ServiceData:
    default: {}
    description: Dictionary packing service data
    type: json
  ServiceNetMap:
    default: {}
    description: Mapping of service_name -> network name. Typically set
                 via parameter_defaults in the resource registry.  This
                 mapping overrides those in ServiceNetMapDefaults.
    type: json
  DefaultPasswords:
    default: {}
    type: json
  RoleName:
    default: ''
    description: Role name on which the service is applied
    type: string
  RoleParameters:
    default: {}
    description: Parameters specific to the role
    type: json
  EndpointMap:
    default: {}
    description: Mapping of service endpoint -> protocol. Typically set
                 via parameter_defaults in the resource registry.
    type: json
  StackUpdateType:
    type: string
    description: >
      Type of update, to differentiate between UPGRADE and UPDATE cases
      when StackAction is UPDATE (both are the same stack action).
    constraints:
    - allowed_values: ['', 'UPGRADE', 'FASTFORWARDUPGRADE']
    default: ''
  MonitoringSubscriptionNovaVNCProxy:
    default: 'overcloud-nova-vncproxy'
    type: string
  NovaVncproxyLoggingSource:
    type: json
    default:
      tag: openstack.nova.vncproxy
      path: /var/log/nova/nova-vncproxy.log
  EnableInternalTLS:
    type: boolean
    default: false
  UseTLSTransportForVnc:
    type: boolean
    default: true
    description: If set to true and if EnableInternalTLS is enabled, it will
                 enable TLS transaport for libvirt VNC and configure the
                 relevant keys for libvirt.
  InternalTLSVncCAFile:
    default: '/etc/ipa/vnc.crt'
    type: string
    description: Specifies the CA cert to use for VNC TLS.
  LibvirtVncCACert:
    type: string
    default: ''
    description: This specifies the CA certificate to use for VNC TLS.
                 This file will be symlinked to the default CA path,
                 which is /etc/pki/libvirt-vnc/ca-cert.pem.
                 This parameter should be used if the default (which comes from
                 the InternalTLSVncCAFile parameter) is not desired. The current
                 default reflects TripleO's default CA, which is FreeIPA.
                 It will only be used if internal TLS is enabled.
