is-ec2 v1.0.2

is-ec2

Sometimes you need to know if you are running on EC2 or not. This will tell you.

npm install is-ec2

var isec2 = require('is-ec2');

if (isec2()) {
  console.log('yep');
}

This works by executing the following command:

if [ -f /sys/hypervisor/uuid ]; then echo `head -c 3 /sys/hypervisor/uuid`; fi

Only work on Linux EC2 instances, not Windows. See this StackOverflow article for details.
