Docker volumes

Docker volumes are the suggested way to persist data outside of a container. These volumes are fully managed by Docker Engine, and these volumes can be writable and readable depending on the configuration when they are used with a Docker command line. The data of these volumes is persisted on a directory path on a host machine.

There is a command-line tool to interact with volumes. The base of this tool is the docker volume command; the --help argument on the end shows the help instructions.
