A10 Networks LBaaS Driver

https://blueprints.launchpad.net/neutron/+spec/a10networks-lbaas-driver

Resubmitting Icehouse BP. Neutron/LBaaS driver for A10 Networks appliances.

Problem description

The new driver would allow using A10 Networks ADC appliances (hardware or software) as backends for Neutron/LBaaS functionality.

Proposed change

The driver will implement the interfaces in the lbaas abstract_driver, using axAPI version 2.1, a JSON HTTP interface for configuring A10 appliances. The currently implemented methods are:

  • create_vip

  • update_vip

  • delete_vip

  • create_pool

  • update_pool

  • delete_pool

  • stats

  • create_member

  • update_member

  • delete_member

  • update_pool_health_monitor

  • create_pool_health_monitor

  • delete_pool_health_monitor

Among the current LBaaS functionality (as of Icehouse), the only unsupported feature is APP_COOKIE persistence.

Driver will support the upcoming Juno LBaaS object model changes. Juno TLS support will be included in a future blueprint.

Work Items

  • A10 driver code

  • Unit tests

  • Voting CI

Dependencies

Driver likely affected by LBaaS model and TLS changes for Juno:

Testing

  • Unit tests

  • A10 QA

  • Existing LBaaS tests provide complete coverage, if driver is installed and configured (as our CI will do.)

  • Not testable in gate, requires hardware. Third party CI will be in place.

Documentation Impact

None.
