Find region from within an EC2 instance

Question

Is there a way to look up the region of an instance from within the instance?

I\'m looking for something similar to the method of finding the instance id.

Answer 1

2 liner that works as long as you are using ec2.internal as your search domain:

az=$(curl -s http://instance-data/latest/meta-data/placement/availability-zone)
region=${az:0:${#az} - 1}
