Hi colleagues,
when I use in [api_settings] section of octavia.conf
api_v1_enabled = False
api_v2_enabled = True
I'm getting member creation failed:

when I use both v1 and v2 enabled, I see ALL calls to API like
http://...:9876/_v1_/... and corresponding log records like
2017-12-04 18:12:01.676 27192 INFO octavia.api._v1_.controllers.*
does "v1" means that neutron use LBaaS API v1 instead of v2 ? Neutron
itself configured to use LBaaS v2 :
[DEFAULT]
service_plugins =
router,neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPluginv2
[service_providers]
service_provider =
LOADBALANCERV2:Octavia:neutron_lbaas.drivers.octavia.driver.OctaviaDriver:default
Is it enough or how to configure both neutron and octavia to use API v2
instead of v1? I'm under Ubuntu 16 and Openstack Pike and there are just
"python-neutron-lbaas" package installed (no lbaasv2-agent,
lbaas-common, etc) and octavia itself (using "pip install octavia" in
_virtual environment_). Thus, endpoints configured unversioned in this way:
+----------------------------------+-----------+--------------+----------------+---------+-----------+--------------------------+
| ID | Region | Service Name | Service
Type | Enabled | Interface | URL |
+----------------------------------+-----------+--------------+----------------+---------+-----------+--------------------------+
| 18862b1bd4c643aca207f8b2d9066895 | RegionOne | octavia |
load-balancer | True | internal | http://lagavulin:9876/ |
| 8cb62ab73fb2431dbc3a0def744852ea | RegionOne | octavia |
load-balancer | True | public | http://lagavulin:9876/ |
| 909e9fc434cb4667bb828828bf49f906 | RegionOne | octavia |
load-balancer | True | admin | http://lagavulin:9876/ |
+----------------------------------+-----------+--------------+----------------+---------+-----------+--------------------------+
and no neutron lbaas agent in the list of agents (since there is no
lbaasv2 agent installed and configured in the system).
Seems I'm missing something.
And two related questions:
* which method to provide API is more preferable - WSGI or standalone
octavia-api process?
* how to be sure that Octavia code matches Pike version? I'm using
"pip install octavia" and it's v1.0.1 at the moment, but not sure it
matches package "python-neutron-lbaas" version 2:11.0.0-0ubuntu1~cloud0
Thank you.
