Using Docker Compose on Windows

Docker 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.” In this post, I will show how you can work with Docker Compose.

Docker on Windows is now commonplace, and it comes with additional features you may not be familiar with. In my previous posts Install Docker and run containers on Windowsand Create a Docker container on Windows with a Dockerfile, I showed you how to create a single container. In this article, I will walk you through how to use docker-compose to create and run multiple containers at once.

Create a Docker container on Windows with a Dockerfile

Add files from your local file system to your Docker container

In my last post, I explained how to install Docker and how to run containers. Today, we will walk through creating a Docker container using a Dockerfile.

A Dockerfile (no file extension) is a definition file that will build and run a container. That container can be a simple Microsoft IIS web application or Python/Flask application or a simple build/reporting service. A definition file helps us with our operational tasks, especially when we are building services or scripts for the repeatable tasks we face on a daily basis.

Docker is an operating-system level virtualization technology that allows you to isolate applications in so-called containers without the overhead of conventional virtual machines. In this post, you’ll learn how to install Docker on Windows and run your first containers.

Docker allows developers building a specific functionality (and all of its dependencies) into a small reproducible environment. This has evolved over time by enabling the ability to create small microservices that do one thing and do it well. I like to think of containers as a Windows Service installed without the need for the entire operating system.
