-==Environment Variables==
-Containerized applications must avoid maintaining configuration in filesystem files - if they do, it limits the reusability of the container. A common pattern used to handle application configuration is to move configuration state into environment variables that can be passed to the application from the container. Docker supports environment variables natively, they are stored in the metadata that makes up a container configuration, and restarting the container will ensure the same configuration is passed to the application each time.
-==Storing Files==
-Storing state into the container's filesystem will not perform well. The space is extremely limited and the state will not be preserved across the container lifecycle.
-==Application State==
-The best use case for Docker is an application that can store state in a centralized location that could be accessed regardless of which host the container runs on.
