Docker Compose Tutorial - Docker in Practice || Docker Tutorial 9

In this Docker Compose Tutorial you will learn what Docker Compose is, why it's useful and how to use it.

Docker Compose is a tool that makes running multiple Docker containers much easier, than with Docker run commands. I show you how docker run command compares to a docker compose file and explain step by step the difference and how it maps from docker run to a docker compose field.

So, basically you can take the whole docker run command with it's configuration and map it into a file. You will get a more structured and re-usable command, especially if you have e.g. 10 docker containers.
