Containers Reverse Proxy

A reverse proxy for routing Docker containers using nginx and docker-gen.

How to run

Build and run on Docker Compose.

docker-compose build
docker-compose up -d

Generated nginx configuration can be shown as follows:

docker-compose exec generator cat /etc/nginx/conf.d/map/generated

How to connect containers and the reverse proxy

Add environment variable(s) and the network to containers as follows:

version: "2"
services:
  app:
    image: node
    environment:
      # Virtual host name for the container.
      VIRTUAL_HOST: app.example.com
      # (Optional) Virtual host port. Defaults to exposed port or 80.
      VIRTUAL_PORT: 8080
    networks:
      - default
      - reverse-proxy-network

networks:
  reverse-proxy-network:
    external:
      # Docker network name.
      name: containersreverseproxy_default

Register init script

We provide the init script for LSB. Register as follows:

sudo ln -s /opt/containers-reverse-proxy/init-lsb.sh /etc/init.d/containers-reverse-proxy
sudo chkconfig --add containers-reverse-proxy
