This document provides an overview of Docker, Docker Compose, and Docker Swarm. It begins with introductions to containers, microservices, and Docker. It then discusses Docker Compose and how it allows defining and running multi-container applications using a YAML file. Docker Swarm is introduced as Docker's native clustering and orchestration layer that provides services discovery, load balancing, and rolling updates. The remainder consists of a demo of building an application using Docker tools and composing it for production using Docker Swarm, followed by suggested next steps.

Where did I left my
Virtual Machine?

5. Docker Definition
● OSS project launched in 2011
● Create, deploy, and run
applications by using
containers.
● The developer can rest assured
that the application will run on
any other Linux machine.
● Significant performance boost
and reduces the size of the
application.

13. Docker Compose
I haven’t understand
Docker yet!

14. Docker Compose Definition
Compose is a tool for defining and
running multi-container Docker
applications. With Compose, you
use a YAML file to configure your
application’s services. Then, with a
single command, you create and
start all the services from your
configuration.

15. Docker Swarm
Is it you,
Kubernetes?

16. Docker Swarm Definition
● Cluster management
integrated with Docker Engine.
● Decentralized design.
● Auto scalability.
● Desired state reconciliation.
● Multi-host networking.
● Service discovery.
● Load balancing.
● Secure by default.
● Rolling update.
