ServiceData:
default: {}
description: Dictionary packing service data
type: json
ServiceNetMap:
default: {}

via parameter_defaults in the resource registry.
type: json
DockerPuppetMountHostPuppet:
type: boolean
default: true
description: Whether containerized puppet executions use modules from the baremetal host. Defaults to true. Can be set to false to consume puppet modules from containers directly.

NeutronEnableL2Pop:
type: string
description: Enable/disable the L2 population feature in the Neutron agents.
default: "False"
NeutronBridgeMappings:
description: >
The OVS logical->physical bridge mappings to use. See the Neutron
documentation for details. Defaults to mapping br-ex - the external
bridge on hosts - to a physical name 'datacentre' which can be used
to create provider networks (and we use this for the default floating
network) - if changing this either use different post-install network
scripts or be sure to keep 'datacentre' as a mapping network name.
