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 Beginner’s Guide to Docker

# Docker Scout
Lots of tools and plugins exist that scan images for known vulnerabilities. We’ll look at Docker Scout, as it’s built into almost every level of Docker, including the CLI, Docker Desktop, Docker Hub, and the  `scout.docker.com`  portal. It’s a very slick service, but it requires a paid subscription. Other similar products and services exist, but most require paid subscriptions.

Recent versions of Docker Desktop have the Scout CLI plugin pre-installed and ready to go. If you’re running a different version of Docker, you may be able to install the CLI plugin from the  [GitHub repo](https://github.com/docker/scout-cli). You can use the `docker scout quickview` command to get a quick vulnerability overview of an image. The following command analyses the `nigelpoulton/tu-demo:latest` image. If a local copy doesn’t exist, it pulls it from Docker Hub and performs the analysis locally.

> **Note:** You cannot execute `docker scout` on our platform due to some restrictions, also because it requires a paid subscription.
