For the last chapter in the book, you will need the ability to run applications in software containers. Docker Desktop (https://www.docker.com/get-started) is an application that allows us to do that. For macOS and Windows, download the installer from the above website corresponding to your operating system and architecture, and follow the instructions to complete the installation.

For Linux, the installation steps will vary depending on your distribution. See https://docs.docker.com/engine/install/#server for detailed steps for your specific distribution. I also recommend that for ease of use (not recommended for production environments), you configure your docker installation to allow non-root users to run containers without using sudo .

Once you have followed the installation steps for your specific operating system, run the following command to download a docker image from Docker Hub and run it to ensure that the installation has been successfully completed:

$ docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 109db8fad215: Pull complete Digest: sha256:0fe98d7debd9049c50b597ef1f85b7c1e8cc81f59c8d 623fcb2250e8bec85b38 Status: Downloaded newer image for hello-world:latest Hello from Docker! This message shows that your installation appears to be working correctly. ..

That completes our software installation for the book. Next, we will quickly cover some conventions used throughout the book.
