OpenStack containerized Nova Metadata service
parameters:
ContainerNovaMetadataImage:
description: image
type: string
ContainerNovaMetadataConfigImage:
description: The container image to use for the nova config_volume
type: string
NovaMetadataLoggingSource:
type: json
default:
tag: openstack.nova.api.metadata
file: /var/log/containers/nova/nova-metadata-api.log
EndpointMap:
default: {}
description: Mapping of service endpoint -> protocol. Typically set
via parameter_defaults in the resource registry.
type: json
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
RoleName:
default: ''
description: Role name on which the service is applied
type: string
RoleParameters:
default: {}
description: Parameters specific to the role
type: json
EnableInternalTLS:
type: boolean
default: false
NovaWorkers:
default: 0
description: Number of workers for Nova services.
type: number
NovaPassword:
description: The password for the nova service and db account
type: string
hidden: true
KeystoneRegion:
type: string
default: 'regionOne'
description: Keystone region for endpoint
NeutronMetadataProxySharedSecret:
description: Shared secret to prevent spoofing
type: string
hidden: true
MonitoringSubscriptionNovaMetadata:
default: 'overcloud-nova-metadata'
type: string
NovaLocalMetadataPerCell:
default: false
description: >
Indicates that the nova-metadata API service has been deployed
per-cell, so that we can have better performance and data isolation in a
multi-cell deployment. Users should consider the use of this configuration
depending on how neutron is setup. If networks span cells, you might need
to run nova-metadata API service globally. If your networks are segmented
along cell boundaries, then you can run nova-metadata API service per cell.
When running nova-metadata API service per cell, you should also configure
each Neutron metadata-agent to point to the corresponding nova-metadata API
service.
