In regular boto 2.38 I used to access instance metadata (e.g. get current stack-name), through boto\'s
boto.utils.get_instance_metadata()
You could use the third-party library ec2-metadata.
Here an example from the docs showing how to get your EC2 region:
pip install ec2-metadata >>> from ec2_metadata import ec2_metadata >>> print(ec2_metadata.region) us-east-1
