      NOTE: updating this setting to a source that is known to provide
      a later version of OpenStack will trigger a software upgrade unless
      action-managed-upgrade is set to True.
  action-managed-upgrade:
    type: boolean
    default: False
    description: |
      If True enables openstack upgrades for this charm via juju actions.
      You will still need to set openstack-origin to the new repository but
      instead of an upgrade running automatically across all units, it will
      wait for you to execute the openstack-upgrade action for this charm on
      each unit. If False it will revert to existing behavior of upgrading
      all units on config change.
  harden:
    type: string
    default:

  ext-port:
    type: string
    default:
    description: |
      [DEPRECATED] Use bridge-mappings and data-port to create a network
      which can be used for external connectivity. You can call the network
      external and the bridge br-ex by convention, but neither is required.
      .
      Space-delimited list of external ports to use for routing of instance
      traffic to the external public network. Valid values are either MAC
      addresses (in which case only MAC addresses for interfaces without an IP
      address already assigned will be used), or interfaces (eth0)
      .
      Note that if data-port is used then this config item is ignored, a
      warning is logged, and the unit is marked as blocked in order to indicate
      that the charm is misconfigured.
  data-port:
    type: string
    default:
    description: |
      Space-delimited list of bridge:port mappings. Specified ports will be
      added to their corresponding specified bridge. The bridges will allow
      usage of flat or VLAN network types with Neutron and should match this
      defined in bridge-mappings.
      .
      Ports can be specified through the name or MAC address of the interface
      to be added to the bridge. If MAC addresses are used, you may provide
      multiple bridge:mac for the same bridge so as to be able to configure
      multiple units. In this case the charm will run through the provided MAC
      addresses for each bridge until it finds one it can resolve to an
      interface name.
      .
      Any changes (subsequent to the initial setting) made to the value of this
      option will merely add the new values along with the existing ones. If
      removal of old values is desired, they have to be done manually through
      the command "ovs-vsctl" in the affected units. If the new values conflict
      with the previous ones, it may cause a network outage as seen in bug

      networks.
  # Legacy (Icehouse) HA
  ha-legacy-mode:
    type: boolean
    default: False
    description: |
      If True will enable Pacemaker to monitor the neutron-ha-monitor daemon
      on every neutron-gateway unit, which detects neutron agents status and
      reschedule resources hosting on failed agents, detects local errors and
      release resources when network is unreachable or do necessary recover
      tasks. This feature targets to < Juno which doesn't natively support HA
      in Neutron itself.

          juju-myservice-0
      If you're running multiple environments with the same services in them
      this allows you to differentiate between them.
  nagios_servicegroups:
    type: string
    default: ""
    description: |
      A comma-separated list of Nagios service groups.
      If left empty, the nagios_context will be used as the servicegroup

  default-availability-zone:
    type: string
    default: 'nova'
    description: |
      Default availability zone to use for agents (l3, dhcp) on this machine.
      If this option is not set, the default availability zone 'nova' is used.
      If customize-failure-domain is set to True, it will override this option
      only if an AZ is set by the Juju provider. If JUJU_AVAILABILITY_ZONE is
      not set, the value specified by this option will be used regardless of
      customize-failure-domain's setting.

      .
      NOTE: Router and Network objects have a property called
      availability_zone_hints which can be used to restrict dnsmasq
      and router namespace placement by DHCP and L3 agents to specific
      neutron availability zones. Neutron AZs are not tied to Nova AZs but
      their names can match.
      .
  customize-failure-domain:
    type: boolean
    default: False
    description: |
      Juju propagates availability zone information to charms from the
      underlying machine provider such as MAAS and this option allows the
      charm to use JUJU_AVAILABILITY_ZONE to set default_availability_zone
      for Neutron agents (DHCP and L3 agents). This option overrides the
      default-availability-zone charm config setting only when the Juju
      provider sets JUJU_AVAILABILITY_ZONE.
  firewall-driver:
    type: string
    default:
    description: |
      Firewall driver to use to support use of security groups with

    type: string
    default:
    description: |
      This option allows setting a path for Firewall Group logs.
      A valid file system path must be provided. If this option is not
      provided Neutron will use syslog as a destination.
      (Available from Stein)
  firewall-group-log-rate-limit:
    type: int
    default:
    description: |
      Log entries are queued for writing to a log file when a packet rate
      exceeds the limit set by this option.
      Possible values: null (no rate limitation), integer values greater than 100.
      WARNING: Should be NOT LESS than 100, if set (if null logging will not be
      rate limited).
      (Available from Stein)
  firewall-group-log-burst-limit:
    type: int
    default: 25
    description: |
      This option sets the maximum queue size for log entries.
      Can be used to avoid excessive memory consumption.
      WARNING: Should be NOT LESS than 25.
      (Available from Stein)
  ovsdb-timeout:
    type: int
    default:
    description: |
      Timeout in seconds for ovsdb commands.
      (Available from Queens)
  ovs-use-veth:
    type: string
    default:
    description: |
      "True" or "False" string value. It is safe to leave this option unset.
      This option allows the DHCP agent to use a veth interface for OVS in
      order to support kernels with limited namespace support. i.e. Trusty.
      Changing the value after neutron DHCP agents are created will break
      access. The charm will go into a blocked state if this is attempted.
  disable-neutron-lbaas:
    type: boolean
    default: False
    description: |
      Manually disable lbaas services. Set this option to True if Octavia
      is used with neutron. This option is ignored for Train+ OpenStack.
  keepalived-healthcheck-interval:
    type: int
    default: 0
    description: |
      Specifies the frequency (in seconds) at which HA routers will check
      their external network gateway by performing an ICMP ping between the
      virtual routers. When the ping check fails, this will trigger the HA
      routers to failover to another node. A value of 0 will disable this
      check. This setting only applies when using l3ha and dvr_snat.
      .
      WARNING: Enabling the health checks should be done with caution as it
      may lead to rapid failovers of HA routers. ICMP pings are low priority
      and may be dropped or take longer than the 1 second afforded by neutron,
      which leads to routers failing over to other nodes.
  enable-auto-restarts:
    type: boolean
    default: True
    description: |
      Allow the charm and packages to restart services automatically when
      required.
