Hello Everyone

Welcome to CloudAffaire and this is Debjeet.

In the last blog post, we have discussed Dockerfile.

In this blog post, we will discuss how to create a multi-container application using docker compose. We will also create a multi-container application using docker-compose.

Prerequisite for this demo:

  • One AWS EC2 instance with Linux 2 AMI and internet access.
  • Docker

What is Docker Compose?

Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration. Docker-compose operates in below three steps

  • Define your app’s environment with a Dockerfile so it can be reproduced anywhere.
  • Define the services that make up your app in docker-compose.yml so they can be run together in an isolated environment.
  • Run docker-compose up and Compose starts and runs your entire app.

To get more details on Docker Compose, please refer below documentation

Next, we are going to create a multi-container application using docker-compose. The application will use the apache web server and phpMyAdmin as frontend and MySQL database as backend running in three different containers and managed by Docker Compose.
