Install Docker

Which Docker should I install?

Linux

Docker only runs natively on Linux. If you are running Linux on your computer, you must install Docker locally.

### macOS

If you have macOS 10.10.3 Yosemite or newer, you can install Docker Desktop for macOS. Docker Desktop for Mac runs as a native Mac application.

If you have an older version of macOS (10.8 Mountain Lion and later) you need to install Docker Toolbox for macOS, which includes Docker Machine, a Linux virtual machine that runs Docker.

Windows

If you have Windows 10 you can install Docker Desktop for Windows. Docker Desktop for Windows runs as a native Windows application. It uses the Hyper-V feature of the Windows OS to virtualize the Docker Engine environment and Linux kernel-specific features for the Docker daemon.

If you have Windows 7 or 8 you need to install Docker Toolbox for Windows, which includes Docker Machine, a Linux virtual machine that runs Docker. It allows you to run Docker commands from your terminal, or from a 'Quickstart terminal' application on your computer.

Installing Docker on Linux

1. If you are running Linux you will need to install Docker directly. You should be logged in as a user with sudo privileges. First, you will need to ensure that you have the command line utility cURL. Do this by opening a terminal and typing:

$ which curl

If cURL is not installed, update your package manager and install it, using:

$ sudo apt-get update
$ sudo apt-get install curl

2. Now that you have cURL, you can use it to get the latest Docker package:

$ curl -fsSL https://get.docker.com/ | sh

3. Add your account to the docker group.

sudo usermod -aG docker <your_username>

This step is required to be able to run Docker commands as a non-root user. You will have to log out and log back in for the change to take effect.

4. Now you should have Docker! Verify that it is installed by running the hello-world container:

$ docker run hello-world
 
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
b901d36b6f2f: Pull complete 
0a6ba66e537a: Pull complete 
Digest: sha256:8be990ef2aeb16dbcb9271cdfa2610fa6658d13f6dfb8bc72074cc1ca36966a7
Status: Downloaded newer image for hello-world:latest


Hello from Docker.

This message shows that your installation appears to be working correctly.
