Docker compose

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.

Features

Multiple isolated environments on a single host
Preserve volume data when containers are created
Only recreate containers that have changed
Variables and moving a composition between environments
