docker-zulip: Nginx won't start, if forced, shows Zulip error 500

Hi,

I’m having some problems with the startup process, here’s what’s happening:

When docker-compose up -d, everything seems ok:

root@ecs:/home/linux# docker-compose up -d
Starting linux_rabbitmq_1
Starting linux_memcached_1
Starting linux_zulip_1
Starting linux_redis_1
Starting linux_database_1

Every container starts and most importantly, stays up. The problem is that nothing happens, no HTTP/HTTPS request is served - if I bash into the Zulip container, /var/log/zulip/install.log says the installation was complete. /var/log/nginx/error.log shows nothing. Using service nginx start, the configured domain shows Zulip’s error 500 page.

After manually starting Nginx, this is what is shown in the logs:

2017/03/23 18:59:54 [crit] 214#0: *6 connect() to unix:/home/zulip/deployments/uwsgi-socket failed (2: No such file or directory) while connecting to upstream, client: 192.168.1.115, server: , request: "GET / HTTP/1.1", upstream: "uwsgi://unix:/home/zulip/deployments/uwsgi-socket:", host: "app.mycompany.com"

My docker-compose.yml is like this:

      ZULIP_USER_FULLNAME: "Vinícius Santana"
    volumes:
      - "/opt/docker/zulip/zulip:/data:rw"
      - "/etc/ssl/:/etc/ssl/"

mail.mycompany.com is a fully functional SMTP server and app.mycompany.com is pointed to the server running the containers.

Thanks a lot!
