Docker example for frontend and backend application

I am learning how to use Docker, and I am in a process of setting up a simple app with Frontend and Backend using Centos+PHP+MySQL.

I have my machine:

  • Running iPython Notebook in Docker container on Amazon EC2 instance
  • Use host networking and additional networks in docker compose
  • AWS cloud form task definition conditional command
  • Persistent mysql data from docker container
  • Opening a port from a docker container on AWS to the rest of the world
  • Where does docker store it's temp files during extraction?
  • In machine “example” i have configured 2 docker containers:

      build: ./frontend
        - ./frontend:/var/www/html
        - ./infrastructure/logs/frontend/httpd:/var/logs/httpd
        - "80"
        - api
      build: ./api
        - ./api:/var/www/html
        - ./infrastructure/logs/api/httpd:/var/logs/httpd
        - "80"
        - mysql:container_mysql

    The issue I am facing is when I access the docker container, I need to specify a port number for either FRONTEND (32771) or BACKEND (32772).

    Is this normal or is there a way to create hostnames for the API and Frontend of the application?

    How does this work on deployment to AWS?

    Thanks in advance.

    If you’re running docker 1.9 or 1.10, and use the 2.0 format for your docker-compose.yml, you can directly access other services through either their “service” name, or “container” name. See my answer on this question, which has a basic example to illustrate this;

    Because the connection between services goes through the private container-container network, you don’t need to use the randomly assigned ports, so if a service publishes/exposes port 80, you can simply connect through port 80

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
