Enabling octavia-dashboard and neutron-lbaas-dashboard
------------------------------------------------------
In general we advise against having both dashboards running at the same
time to avoid confusing users, which is exaggerated since the dashboards
will have the same label.
In rare circumstances, e.g. as part of a migration strategy, it might be
necessary to do so. The main issue to watch out for is to avoid neutron-lbaas
and Octavia getting out of sync and neutron-lbaas-dashboard showing phantom
load balancers - this can be avoided if the sync between Octavia and
neutron-lbaas is fully enabled.
Here is a table to show some cases:
+---------------+-----------------+----------------+-----------+--------------+
| Configuration | Configuration | neutron-lbaas- | octavia- | Notes |
| neutron-lbaas | Octavia | dashboard | dashboard | |
| | | enabled | enabled | |
+---------------+-----------------+----------------+-----------+--------------+
| not installed | v2 API enabled | not supported | preferred | |
+---------------+-----------------+----------------+-----------+--------------+
| octavia-driver| v2 API disabled | supported | not | sync |
| | v1 API enabled | | supported | required |
+---------------+-----------------+----------------+-----------+--------------+
| octavia-driver| v2 API enabled | supported | preferred | sync |
| | v1 API enabled | | | required |
+---------------+-----------------+----------------+-----------+--------------+
| octavia-proxy | v1 API disabled | Supported (but | preferred | |
| plugin | v2 API enabled | not | | |
| | | recommended) | | |
+---------------+-----------------+----------------+-----------+--------------+
| no octavia | not installed | preferred | not | |
| driver but | | | supported | |
| other drivers | | | | |

| no octavia | v2 API enabled | preferred | preferred | independent |
| driver but | v1 API disabled | | | services |
