Hi,

In Kolla we use port 8780 for placement-api, OSA also use same port and TripleO 8778. To make placemenent-api HA under HAproxy just need to bind the VIP for whatever port are you using for placement endpoint (This port may vary from deployments method).

An example config for placement-api in HAproxy:

listen placement_api
  bind 192.168.100.10:8780
  http-request del-header X-Forwarded-Proto
  server controller 192.168.100.244:8780 check inter 2000 rise 2 fall 5
  server controller2 192.168.100.186:8780 check inter 2000 rise 2 fall 5

Regards

The port you use to host placement behind haproxy doesn't really matter. It doesn't have to even be a special port. It is perfectly fine to put it on port 80 or port 443 is there is nothing else running on the web server, or if a prefix (such as /placement) is being used.

What matters is what the haproxy exposes to the rest of the world and what is in the service catalog. Ideally the service in the catalog would not use non-standard HTTP ports but would instead either use prefixes or hostnames, e.g. things like:

• https://cloud.example.com/placement
• http://placement.cloud.example.com/
