3CX in Docker container behind nginx-proxy with letsencrypt

[Bret Gordon]

Has anyone tried this? I've searched around, but I haven't found anything.

It should be fairly straightforward to set up a Dockerfile that pulls from Debian 8 and loads up 3CX, so the real challenge will be setting up the nginx reverse-proxy. I'll start playing around with it, but any suggestions are greatly appreciated.

If anyone has 3CX running behind an nginx reverse-proxy, I would LOVE to see your config!

I'll post a docker-compose.yml file here if/when I ever get this going properly.

For starters, here's my standard docker-compose.yml for nginx-proxy/letsencrypt. Note that there is no "networks" config -- it will create "nginx_default" (i put it in a folder named "nginx") that you attach other containers to behind it:

version: '2'

services:
  nginx-proxy:
    image: jwilder/nginx-proxy
    container_name: nginx-proxy
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ./vhost.d:/etc/nginx/vhost.d
      - /usr/share/nginx/html
      - ./certs:/etc/nginx/certs:ro
      - ./conf.d/:/etc/nginx/conf.d
      - /var/run/docker.sock:/tmp/docker.sock:ro
    restart: always

  letsencrypt-nginx-proxy-companion:
    image: jrcs/letsencrypt-nginx-proxy-companion
    container_name: letsencrypt-nginx-proxy-companion
    volumes_from:
      - nginx-proxy
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./certs:/etc/nginx/certs:rw
    restart: always

For example, a Wordpress container connected to the proxy:

version: '2'

services:
  db-wordpress:
    image: mysql:5.7
    container_name: db-wordpress
    volumes:
      - ./db-wordpress:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=wordpress
      - MYSQL_DATABASE=wordpress
      - MYSQL_USER=wordpress
      - MYSQL_PASSWORD=wordpress
    networks:
      - proxy-tier
    restart: always

  wordpress:
    depends_on:
      - db-wordpress
    image: wordpress
    container_name: wordpress
    volumes:
      - ./html:/var/www/html
    environment:
      - WORDPRESS_DB_HOST=db-wordpress:3306
      - WORDPRESS_DB_PASSWORD=wordpress
      - WORDPRESS_DB_USER=wordpress
      - VIRTUAL_HOST=example.com,www.example.com
      - LETSENCRYPT_HOST=example.com,www.example.com
      - [email protected]
    networks:
      - proxy-tier
    restart: always

networks:
  proxy-tier:
    external:
      name: nginx_default

There REALLY shouldn't be any reason why this won't work! Like I said, I think it is just a matter of getting a proper reverse-proxy config file set up.

NOBODY??? Guess I have to do everything myself, lol

hi bret, any success so far? i got that question from a future customer today...

I haven't had a chance to get into it yet, unfortunately. I just bought a refurb R900 where it will eventually live, but I'm having issues with the CPU's overheating and a stick of bad RAM somewhere. So I need to take care of that first.

Like I said, though, the trick is going to be in the proxy config, so I'll start looking to see how people might be doing it with other PBX's and go from there. I really don't see any reason why it wouldn't work.
