OpenStack containerized Neutron L3 agent
parameters:
DockerNeutronL3AgentImage:
description: image
type: string
DockerNeutronConfigImage:
description: The container image to use for the neutron config_volume
type: string
DockerNeutronL3AgentUlimit:
default: ['nofile=16384']
description: ulimit for Neutron L3 Agent Container
type: comma_delimited_list
NeutronL3AgentLoggingSource:
type: json
default:
tag: openstack.neutron.agent.l3
path: /var/log/containers/neutron/l3-agent.log
NeutronEnableKeepalivedWrapper:
description: Generate a wrapper script so neutron launches keepalived processes in a
separate container.
type: boolean
default: true
NeutronEnableHaproxyDockerWrapper:
description: Generate a wrapper script so neutron launches haproxy in a separate container.
type: boolean
default: true
NeutronEnableDibblerDockerWrapper:
description: Generate a wrapper script so neutron launches the dibbler client in a separate
container.
type: boolean
default: true
NeutronEnableRadvdDockerWrapper:
description: Generate a wrapper script so neutron launches radvd in a separate container. Note
that is currently disabled by default pending availability of a fix to radvd
(see https://bugzilla.redhat.com/show_bug.cgi?id=1564391). It will be enabled by default
once the fix to radvd is generally available across target distributions.
type: boolean
default: false
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

type: json
NeutronL3AgentRadvdUser:
default: "root"
description: |
The username passed to radvd, used to drop root privileges and change
user ID to username and group ID to the primary group of username. If no
user specified, the user executing the L3 agent will be passed. If "root"
specified, because radvd is spawned as root, no "username" parameter
will be passed
