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

Was also looking for a solution to find region from the instance and here is my pure Bash solution:

az=$(curl -s http://169.254.169.254/latest/meta-data/placement/availability-zone)
region=${az:0:${#az}-1}

unless there are regions where AZ has more than two letters, which I'm not aware of.
