If you want to thrive in the modern cloud-first world, you need to know Docker. But don’t stress, this course will give you all the skills you need.

To kick things off, you will learn how to deploy apps with Docker Compose, a key tool for managing multi-container applications running in single-engine mode. You will then move onto Docker Swarm which will allow you to stand up containers and orchestrate them at scale.

Towards the back half of the course, you will take a deep dive into Docker Networking, deploying apps with Docker Stacks, and some of the industry tools used for keeping Docker secure.

By the end of this course, you will be equipped with the knowledge and tools to run Docker at scale, no matter how many containers you have.

Docker Deep Dive: Advanced Techniques

## Image scanners
Image scanners work by inspecting images and searching for packages that have known vulnerabilities. Once you know about these, you can update the packages and dependencies to versions with fixes.

### Limitations
As good as image scanning is, it's important to understand its limitations. 

* Image scanning is focused on images and does not detect security problems with networks, nodes, or orchestrators. 

* Not all image scanners are equal; some perform deep binary-level scanning to detect packages, whereas others simply look at package names and do not closely inspect the content of images.

At the time of writing, Docker Hub **does not** offer image scanning services. This may change in the future. Some on-premises private registry solutions offer built-in scanning, and there are third-party services that offer image scanning services.

### Example
The figures below are included as an example of the kind of reports image scanners can provide.
