Simple Apache + Nginx Reverse Proxy Example in Docker Compose

README.md

1. download these two files to the same directory
2. docker-compose up
3. http://localhost should show you "it works" which is apache being reverse-proxied through nginx
4. docker sets up DNS for web based on compose service name so the nginx front-end can find http://web
5. proxy is set to listen on public port 80 on host so it'll receive incoming traffic, then push to httpd

docker-compose.yml

version: '3'

services:
  proxy:
    image: nginx:1.11 # this will use the latest version of 1.11.x
    ports:
      - '80:80' # expose 80 on host and sent to 80 in container
    volumes:
      - ./nginx.conf:/etc/nginx/conf.d/default.conf:ro
  web:
    image: httpd  # this will use httpd:latest

nginx.conf

server {

	listen 80;

	location / {

		proxy_pass         http://web;
		proxy_redirect     off;
		proxy_set_header   Host $host;
		proxy_set_header   X-Real-IP $remote_addr;
		proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
		proxy_set_header   X-Forwarded-Host $server_name;

	}
}

sir i want to use nginx as a load balancer and proxy server . so can i do this tasks with docker-compose..???
i'm just asking this because after running container with docker-compose they don't get and ip.!!

and sir how can combine docker-swarm with docker-compose

Hi Bret, I am getting the below error:

This is because , maybe you are using a docker toolbox in windows. The following docker-compose.yml file contains the volumes.. which will only work with docker toolbox in windows ...only if you put the docker-compose.yml and nginx.conf inside the C:/Users// directory.
