class NoopAmphoraLoadBalancerDriver

  Bases: `AmphoraLoadBalancerDriver`, `VRRPDriverMixin`

  check(amphora, timeout_dict=None)

    Check connectivity to the amphora.

    Parameters:

      - amphora – The amphora to query.

      - timeout_dict – Dictionary of timeout values for calls to the amphora. May contain: req_conn_timeout, req_read_timeout, conn_max_retries, conn_retry_interval

    Raises:

      TimeOutException – The amphora didn’t reply

  delete(listener)

    Delete the listener on the vip.

    Parameters:

      listener (octavia.db.models.Listener) – listener object, need to use its protocol_port property

    Returns:

      return a value list (listener, vip, status flag–delete)

    At this moment, we just build the basic structure for testing, will add more function along with the development.

  finalize_amphora(amphora)

    Finalize the amphora before any listeners are configured.

    Parameters:

      amphora (octavia.db.models.Amphora) – amphora object, need to use its id property

    Returns:

      None

    At this moment, we just build the basic structure for testing, will add more function along with the development. This is a hook for drivers who need to do additional work before an amphora becomes ready to accept listeners. Please keep in mind that amphora might be kept in an offline pool after this call.

  get_diagnostics(amphora)

    Return ceilometer ready diagnostic data.

    Parameters:

      amphora (octavia.db.models.Amphora) – amphora object, need to use its id property

    Returns:

      return a value list (amphora.id, status flag–‘ge t_diagnostics’)

    At this moment, we just build the basic structure for testing, will add more function along with the development, eventually, we want it run some expensive self tests to determine if the amphora and the lbs are healthy the idea is that those tests are triggered more infrequent than the health gathering.

  get_info(amphora, raise_retry_exception=False)

    Returns information about the amphora.

    Parameters:

      - amphora (octavia.db.models.Amphora) – amphora object, need to use its id property

      - raise_retry_exception – Flag if outside task should be retried

    Returns:

      return a value list (amphora.id, status flag–‘info’)

    At this moment, we just build the basic structure for testing, will add more function along with the development, eventually, we want it to return information as: {“Rest Interface”: “1.0”, “Amphorae”: “1.0”, “packages”:{“ha proxy”:”1.5”}} some information might come from querying the amphora

  get_interface_from_ip(amphora, ip_address, timeout_dict=None)

    Get the interface name from an IP address.

    Parameters:

      - amphora (octavia.db.models.Amphora) – The amphora to query.

      - ip_address (string) – The IP address to lookup. (IPv4 or IPv6)

      - timeout_dict (dict) – Dictionary of timeout values for calls to the amphora. May contain: req_conn_timeout, req_read_timeout, conn_max_retries, conn_retry_interval

  post_network_plug(amphora, port, amphora_network_config)

      - amphora_network_config (octavia.network.data_models. AmphoraNetworkConfig) – A data model containing information about the subnets and ports that an amphorae owns.

    This method is optional to implement. After adding an amphora to a network, there may be steps necessary on the amphora to allow it to access said network. Ex: creating an interface on an amphora for a neutron network to utilize.

  post_vip_plug(amphora, load_balancer, amphorae_network_config, vrrp_port, vip_subnet, additional_vip_data=None)

    Called after network driver has allocated and plugged the VIP

      - vip_subnet (octavia.network.data_models.Subnet) – VIP subnet associated with the load balancer

    Returns:

      None

    This is to do any additional work needed on the amphorae to plug the vip, such as bring up interfaces.

    Parameters:

      - loadbalancer (octavia.db.models.LoadBalancer) – loadbalancer object to reload listeners
