Find region from within an EC2 instance

Question

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

Answer 1

Use this:

EC2_AVAIL_ZONE=`curl -s http://169.254.169.254/latest/meta-data/placement/availability-zone`

EC2_REGION="`echo \"$EC2_AVAIL_ZONE\" | sed 's/[a-z]$//'`"
