Running laravel/lumen in Docker using docker-compose

Question

I am learning about microservice architecture and I want to setup a simple lumen app to run inside 3 separate containers using docker-compose

• web - this will run my nginx front server
• app - this will run my php-fpm
• database - this will run my mysql server

This is my docker-compose.yml

version: '2'
services:

  # The Web Server
  web:
    build:
      context: ./
      dockerfile: ./deploy/web.dockerfile
    working_dir: /var/www
    volumes_from:
      - app
    ports:
      - 8080:80
    depends_on:
      - app

  # The Application
  app:
    build:
      context: ./
      dockerfile: ./deploy/app.dockerfile
    working_dir: /var/www
    volumes:
      - ./:/var/www
    environment:
      - "DB_PORT=3306"
      - "DB_HOST=database"

  # The Database
  database:
    image: mysql:5.7
    volumes:
      - dbdata:/var/lib/mysql
    environment:
      - "MYSQL_ROOT_PASSWORD=secret"
      - "MYSQL_DATABASE=homestead"
      - "MYSQL_USER=homestead"
    ports:
        - "33061:3306"

volumes:
  dbdata:

        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }
}

When I run docker-compse up I can see everything is running fine:

But when I visit http://127.0.0.1:8080 I get the This site can't be reached error in chrome.

I am on windows using Docker Toolbox, and my docker version is: Docker version 17.10.0-ce, build f4ffd25

Any ideas how to properly setup LEMP stack on docker to run a simple lumen app?

Answer 1

Docker Toolbox is an older solution for Docker on Windows and Mac. There is no local host proxy from containers (you cannot use localhost to get to container exposed ports).

With Docker Toolbox actually comes Docker Machine, which is running a virtual machine behind the scenes and this virtual machine has a IP address. You can get the IP address using:

docker-machine ip

Or:

docker-machine ip default

It will give you something like 192.168.88.100. You would then use this address to get to your exposed ports such as http://192.168.88.100:8080/ .

Alternatively, you could remove the Docker Machine using docker-machine rm , uninstall Docker Toolbox, and then install Docker for Windows instead which will allow you to access published container ports on localhost .
