WHAT THAT ELIMINATES
"It works on my machine."
WHAT TO DEFINE

WHAT THAT USUALLY INCLUDES
The application A database A cache, where used A queue, where used
WHAT TO MOUNT

Database data, so it survives restarts.
WHAT TO KEEP OUT

WHAT THIS ENABLES
A new person running the full stack in minutes.
WHAT TO DOCUMENT
The commands to start, stop and reset.
WHAT TO BE CAREFUL WITH
Performance of mounted files on some systems Resource use, which can be substantial
WHAT TO PROVIDE
A way to reset to a clean state.
