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

## Pushing updates to an application

Pushing updates to deployed applications is a fact of life and for the longest time, it was really painful. I've lost more than enough weekends to major application updates, and I've no intention of doing it again.


Well, thanks to Docker *services*, pushing updates to well-designed microservices apps is easy.

### Creating an overlay network
To see this, we're going to deploy a new service. But before we do that, we're going to create a new overlay network for the service. This isn't necessary, but I want you to see how it is done and how to attach the service to it.
