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

# The sample app
We'll use the sample app shown in figure below with two services, a network, and a volume. 


The `web-fe` service runs a web server that increments a counter in the `redis` service every time it receives a request for the web page. Both services are connected to the `counter-net` network and use it to communicate with each other. The `web-fe` service mounts the `counter-vol` volume. 

This is all defined in the `compose.yaml` file in the `multi-container` folder of the course GitHub repo.
# Clone the repository
If you haven't already done so, clone the repo so you have a local copy of everything you'll need. You'll need `git` installed, and the command will create a new directory called `ddd-book`.


Get introduced to a sample multi-container application with web services defined in the compose.yaml file.
