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.

# Scaling services

Another powerful feature of services is the ability to scale them up and down by adding or removing replicas.

Assume business is booming and you’re experiencing double the number of requests to your web front-end. Fortunately, you can easily scale the number of replicas with the `docker service scale` command.

Run the following command to scale the **web-fe** service from 5 to 10 replicas.
