ec2control / README.rst

Allows control of EC2 instances via email.

Installation is via procmail or any other system that can route email messages to the script.

Copy the file ec2control.ini.SAMPLE to ec2control.ini.

The script is then invoked as ec2control --config /path/to/ec2control.ini, with the email text as standard input.

An email sends the command via the subject line:

"startup"

or

"startup <instancename>"
