Working With Prebuilt Docker Images
After installation, the best way to familiarize yourself with Docker, is to run containers from a few prebuilt images. In this lab, you will explore Docker Hub for images that will run a website. Once you find suitable images, you will get them into your development environment, and begin experimenting. You will run, stop, and delete containers from those images. You will also learn how to use existing data in containers.
