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

- `docker stack deploy` is the command for deploying **and** updating stacks of services defined in a stack file (usually called `docker-stack.yml`).

- `docker stack ls` lists all stacks on the Swarm, including how many services they have.
- `docker stack ps` gives detailed information about a deployed stack. It accepts the name of the stack as its main argument, lists which node each replica is running on, and shows *desired state* and *current state*.
- `docker stack rm` deletes a stack from the Swarm. It does not ask for confirmation before deleting the stack.

This lesson lists all the relevant Docker stack commands with brief reminders of what each one does.
