Before getting started, you need to ensure that you have the required tools installed on your computer. You will need:
Docker needs to download container images from Docker Hub, which is a public repository for...right, Docker images. Ensure that you have a working connection before beginning the exercises.
We recommend VSCode, which is available for most platforms: https://code.visualstudio.com/
You may also want to install the Docker extension for VSCode, which adds syntax highlighting and a few other nice tools. You can read more about installing extensions here.
Official install guides are available for Linux, Mac and Windows.
When your installation has completed, try running the following command in a terminal:
docker run hello-world
If you see the following lines in your output your docker installation is working correctly!
Hello from Docker!
This message shows that your installation appears to be working correctly.
You are now ready to start with Chapter 1!
