boto3 equivalent to boto.utils.get_instance_metadata()?

Question

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() 

Is there an equivalent in boto3, or do I need to go to the down level direct http address to fetch metadata about the running instance?

Answer 1

Nope, still no equivalent in boto3, just hit this gap myself.
They have an open feature request for this https://github.com/boto/boto3/issues/313 that references this question.

As for workarounds,
you can continue to use boto.utils or use urllib/urllib2 to do the HTTP requests manually ie.

# Python2 import urllib2 instanceid = urllib2.urlopen('http://169.254.169.254/latest/meta-data/instance-id').read()  # Python3 import urllib.request instanceid = urllib.request.urlopen('http://169.254.169.254/latest/meta-data/instance-id').read().decode() 

see What is the quickest way to HTTP GET in Python? for a quick intro on urllib and http://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/ec2-instance-metadata.html#instancedata-data-categories for the URI structure of the metadata service.

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
