Research direction

Start at the Docker CLI's docker run entry point and review the existing --volumes-from behavior. Define how --env-from should inherit environment variables from referenced containers, then verify that the option is accepted and produces the intended environment in a running container.

Description

When running an image via the docker run command you've got the option --volumes-from, allowing you to inherit the passed volumes from the referenced Docker containers. It would be nice to provide also option --env-from, allowing you to - by the analogy - inherit the passed environment variables from other containers, saving the need to redefine them.
