Containers have revolutionized the IT world and it can be hard to know where to start. In this course, Docker Captain Nigel Poulton guides you through the basics all the way to proficiency.

You'll learn why we have containers and how they work. You’ll run through the basics like images, the Docker engine, and containers. With the basics out of the way, you'll then containerize an application and learn how to run it. Throughout the course, Nigel will demystify all the jargon and buzzwords. When you're done, you'll be ready to use Docker in the real world.

The Beginners Guide to Docker

In the Op section of the chapter, you downloaded a Docker image, launched a
container from it, logged into the container, executed a command inside of it, and then stopped and deleted the container.

In the Dev section, you containerized a simple application by pulling some source code from GitHub and building it into an image using instructions in a Dockerfile.

You then ran the containerized app.

This big-picture view should help you with the up-coming chapters where we will
dig deeper into images and containers.
