Docker-Compose Explanation

Introduction

Docker-compose is a tool that combines and runs multiple containers of interrelated services with a single command. It is a tool to define all the application dependencies in one place and let the Docker take care of running all of those services in just one simple command docker-compose up.

If you are following this course on your local machine remember to install the Docker Compose from the official documentation website.

Clone the git repo using git clone https://github.com/venky8283/Docker.git . Type git checkout 4de325cf1da2428e757be4f2bcc53f35c384c598 to get to the code used in this lesson.
