Subject: Heat + A10 LBaaS v1 driver - Error 33619969

Hi Doug, 
hope you are dowing 
We are using the A10 lbaas V1 driver with heat to provide autoscaling services.

Each time we try to delete a stack, we are getting te following Exception

These are the heat resources involved (showing just the relevant ones)

  pool:
    type: OS::Neutron::Pool
    properties:
      protocol: HTTP
      monitors: [{get_resource: monitor}]
      subnet: a10-subnet2
      lb_method: ROUND_ROBIN
      vip:
        protocol_port: 8080


  lb:
    type: OS::Neutron::LoadBalancer
    properties:
      protocol_port: 8080
      pool_id: {get_resource: pool}


  monitor:
   type: OS::Neutron::HealthMonitor
   properties:
     type: HTTP
     delay: 12
     max_retries: 5
     timeout: 10
     http_method: "GET"
     max_retries: 2
     timeout: 5
     url_path: "/"
     expected_codes: "200"


I'm also attaching the neutron-server log extract, for further details

Have you seen this problem before? I'm guessing that this is related with the way that heat handles dependencies when a stack delete is requested. 

Thanks in advance!

need to populate binding:host_id on port

probably optionally via a config toggle

Non-existent config causes driver to crash

If /etc/a10/config.py or other config paths don't exist (we should store these in a constant...) don't exist, the driver bombs and doesn't give enough info about said non-existence.
REPRODUCTION: Use v1 of the driver without creating a configuration. Observe neato traceback.

Fix v2.1 auto SNAT in vport creation

In 2.1 of acos client, the vport JSON structure is not correctly created with "auto_source_nat" specified when autosnat is specified in the device configuration.

v2 needs stats/refresh work

add ipinip option to config file

For now, global boolean. If true, then in handle_listener,

add: 'ip_in_ip': True

to the axapi_args vport dict.

And that axapi_args vport dict has a bug; it's currently 'port', which will never merge into the right dictionary in acos-client.

Null reference exception in v1 VIP handler

This was an issue that came up before VXLAN stabilization. If the device has more than one partition, acos_client returns an error when we wire in the certificate hooks.
