When you define your app with Compose in development, you can use this definition to run your application in different environments such as CI, staging, and production. Swarm mode combines the ability to not only define the application architecture, like Compose, but to define and maintain high availability levels, scaling, load balancing, and more. Running containerized applications on multi-node swarms involves specific data portability and replication handling that are not covered here. To run Docker in swarm mode, you can either create a new swarm or have the container join an existing swarm. Keep your Dockerfiles and images small, efficient, and fast.
