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

There are a few prerequisites that need taking care of before deploying the app:

- **Swarm mode:** We'll deploy the app as a Docker Stack, and stacks require Swarm mode.
- **Labels:** One of the Swarm worker nodes needs a custom node label.
- **Secrets:** The app uses secrets that need pre-creating before it can be deployed.

## Sample app

We'll build a three-node Linux-based Swarm cluster that satisfies all of the application's prereqs. Once we're done, the lab will look like this.
