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

Every manager and worker that joins a swarm is issued a client certificate. This certificate is used for mutual authentication. It identifies the node, the swarm that it's a member of, and the role the node performs in the swarm (manager or worker).

## Inspecting a client certificate
You can inspect a node's client certificate on Linux nodes with the following command.
