minecraft manager (mm)

A minecraft server that lives in a cloud environment to:

• update dns for the random cloud IP address it was given
• monitor minecraft server usage (player stats) and turn off if idle
• make it easy to turn it on on-demand (not yet implemented)

Components

• cfdns is a wrapper around cloudflare dns sdk to check the current running systems’ external IP and update a dns domain if needed.

• Active Or Die is a lightweight utility for monitoring active connections on a specified port. If no activity exists for a defined amount of time, the server is powered off.
