By now, you've probably heard the buzz around Docker. It's fundamentally changed the development process and been adopted by software teams of all sizes, and for good reason: Docker makes it considerably easier to create, deploy, and run applications with the use of containers.

Docker is here to stay, and is becoming one of the most in-demand technologies on the market. Mastering it now will help you produce better software, level up your career, and stand out from the crowd. Get started today.

Docker for Developers

# Windows 10

*Docker Desktop* requires a Professional, Home, Enterprise or Education 64-bit edition of Windows 10, because it is based on Hyper-V.

> If you have a desktop version of Windows that doesn't meet the requirements, you may use the older [Docker Toolbox](https://docs.docker.com/toolbox/overview/) based on VirtualBox.

Before you install Docker Desktop it's important that you:

* enable Hyper-V
* enable hardware virtualization in the BIOS

Then, follow [this link](https://docs.docker.com/docker-for-windows/install/) and follow the instructions found there.

During installation, you will be prompted whether to use Windows or Linux containers. I'd suggest Linux containers because:

* You can change your mind at any moment later on, just right-click the Docker icon in your toolbar and select "Switch to Windows containers..."
* As of now, most containers images are based on Linux

# Linux

There are other Docker packages available and you can simply follow the steps depending on your version:

* [CentOS 7](https://docs.docker.com/install/linux/docker-ce/centos/)
* [Debian or Raspbian](https://docs.docker.com/engine/installation/linux/debian/)
* [Fedora 26+ 64-bit](https://docs.docker.com/engine/installation/linux/fedora/)
* [Ubuntu Bionic, Xenial or Trusty 64-bit](https://docs.docker.com/install/linux/docker-ce/ubuntu/)

Whatever your Linux flavor, there are common post-installation steps [here](https://docs.docker.com/install/linux/linux-postinstall/). Make sure that you read them carefully. Double-check them if you cannot successfully run the [hello-world test](https://www.educative.io/courses/docker-for-developers/various-products-for-various-needs).

# Mac

*Docker Desktop* requires a Mac OS Sierra 10.12 or above.

> If you have an older macOS version, you may use the older [Docker Toolbox](https://docs.docker.com/toolbox/overview/) based on VirtualBox.

Now that we have successfully set up Docker on our machines, let's go over some basic concepts in the next chapter. 

In this lesson, you will be given machine specific instructions on how to install Docker Desktop on your local machine.
