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


We store images in centralized places called *image registries*. This makes it easy to share and access them. 

The most common registry is [Docker Hub](https://hub.docker.com). But other registries exist, including 3rd party registries and secure on-premises registries. However, the Docker client is opinionated and defaults to using Docker Hub. We'll be using Docker Hub for the rest of the course.



Take a look at the official and unofficial Docker image registries.
