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

A cleanly installed Docker host does not have any images in its local repository.

The local image repository on a Linux-based Docker host is usually located at `/var/lib/docker/<storage-driver>`. On Windows-based Docker hosts, this is `C:\ProgramData\docker\windowsfilter`. If you're using Docker on your Mac or PC with Docker Desktop, everything runs inside of a VM.

You can use the following command to check if your Docker host has any images in its local repository.
