octavia_lib.api.drivers.provider_base module

class octavia_lib.api.drivers.provider_base.ProviderDriver

Bases: object

create_vip_port(loadbalancer_id, project_id, vip_dictionary, additional_vip_dicts)

Creates a port for a load balancer VIP.

If the driver supports creating VIP ports, the driver will create a VIP port with the primary VIP and all additional VIPs added to the port, and return the vip_dictionary populated with the vip_port_id and a list of vip_dictionaries populated with data from the additional VIPs (which are guaranteed to be in the same Network). This might look like: {‘port_id’: port_id, ‘subnet_id’: subnet_id_1, ‘ip_address’: ip1}, [{‘subnet_id’: subnet_id_2, ‘ip_address’: ip2}, {…}, {…}] If the driver does not support port creation, the driver will raise a NotImplementedError.

Parameters:

  • loadbalancer_id (string) – ID of loadbalancer.

  • project_id (string) – The project ID to create the VIP under.

Param:

vip_dictionary: The VIP dictionary.

Param:
