create_port(network_id, name=None, fixed_ips=(), secondary_ips=(), security_group_ids=(), admin_state_up=True, qos_policy_id=None, vnic_type='normal')

Creates a network port.

fixed_ips = [{‘subnet_id’: <id>, (‘ip_address’: <IP>’)},] ip_address is optional in the fixed_ips dictionary.

Parameters:

• network_id – The network the port should be created on.

• name – The name to apply to the port.

• fixed_ips – A list of fixed IP dicts.

failover_preparation(amphora)

Prepare an amphora for failover.

Parameters:

get_network_configs(loadbalancer, amphora=None)

Retrieve network configurations

This method assumes that a dictionary of AmphoraNetworkConfigs keyed off of the related amphora id are returned. The configs contain data pertaining to each amphora that is later used for finalization of the entire load balancer configuration. The data provided to these configs is left up to the driver, this means the driver is responsible for providing data that is appropriate for the amphora network configurations.

Example return: {<amphora.id>: <AmphoraNetworkConfig>}

Parameters:

• load_balancer – The load_balancer configuration

• amphora – Optional amphora to only query.

Returns:

dict of octavia.network.data_models.AmphoraNetworkConfig keyed off of the amphora id the config is associated with.

Raises:

NotFound, NetworkNotFound, SubnetNotFound, PortNotFound

get_network_ip_availability(network)

network – octavia.network.data_models.Network

Returns:

octavia.network.data_models.Network_IP_Availability

Raises:

NetworkException, NetworkNotFound

get_plugged_networks(compute_id)

Retrieves the current plugged networking configuration.

Parameters:

compute_id – id of an amphora in the compute service

Returns:

[octavia.network.data_models.Instance]

get_port(port_id, context=None)

Retrieves port from port id.

Parameters:

• port_id – id of a port to retrieve

• context – A request context

Returns:

octavia.network.data_models.Port

Raises:

NetworkException, PortNotFound

get_port_by_name(port_name)

Retrieves port from port name.

Parameters:

port_name – name of a port to retrieve

Returns:

octavia.network.data_models.Port

Raises:

NetworkException, PortNotFound

get_port_by_net_id_device_id(network_id, device_id)
