Docker Bible

Docker Bible

who have been involved in the early Docker efforts created our version of a "Docker Bible."
The most important aspect of this documentation is that it provides "how to's" that are specific
to some projects, codifies design patterns, and provides specific projects do's and don'ts.
This will be a living document that we add to as we go.

Here is the Table of Contents for our Docker Bible:
