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 `docker service ls` command
Run a `docker service ls` command to see a list of all the services on your swarm.


$ docker service ls
ID         NAME      MODE         REPLICAS   IMAGE                      PORTS
z7o...uw   web-fe    replicated   5/5        Educative-Content/ddd...   *:8080->8080/tcp

The output shows a single service along with some basic config and state info. Among other things, you can see the name of the service and that all five replicas are running. Some of the replicas might not be in the running state if you run the command too soon after deploying the service. This is usually because the workers are still pulling the image and starting the replicas.

# The `docker service ps` command
You can run a `docker service ps` command to see a list of service replicas and the state of each.
