I am trying to stand up 2 ghost containers, with mysql on the back end with eeacms/haproxy as the load balancer in docker containers error 503 - docker-compose

Question

I have tried many configurations and scenarios based around this which is mostly a tutorial that stops at one ghost instance. I am trying to scale it to 2 with docker-deploy up -d --scale ghost=2. When I hit the individual IP;s of the ghost containers , they work but port 80 is 503.
version: "3.1"
volumes:
mysql-volume:
ghost-volume:

ghost-network:
services:
mysql:
image: mysql:5.7
container_name: mysql
volumes:
- mysql-volume:/var/lib/mysql

depends_on:

entrypoint: ["wait-for-it.sh", "mysql", "--", "docker-entrypoint.sh"]

haproxy:
image: eeacms/haproxy
depends_on:
- ghost
ports:
- "80:5000"
- "1936:1936"
environment:
BACKENDS: "ghost"
DNS_ENABLED: "true"
LOG_LEVEL: "info"
What I get on localhost:80 is a 503 error the particular eeacms/haproxy image is supposed to be self-configuring any help appreciated

Answer 1

I needed to add a backend URL to the environment and also tell ghost it was installed in an alternate location by adding URL: localhost:5050
