Description Carlos Goncalves 2019-10-30 17:14:33 UTC

When we boot up amphora for an active/standby topology, we should leverage the Nova anti-affinity capabilities to place the amphora on different hosts.

Puppet-octavia already provides support to enable anti-affinity. Director should enable it out of the box.
