How to choose an AWS profile when using boto3 to connect to CloudFront
PythonAmazon Web-ServicesBoto3Amazon IamAmazon CloudfrontPython Problem Overview
I am using the Boto 3 python library, and want to connect to AWS CloudFront. I need to specify the correct AWS Profile (AWS Credentials), but looking at the official documentation, I see no way to specify it.
I am initializing the client using the code:
client = boto3.client('cloudfront')
However, this results in it using the default profile to connect. I couldn't find a method where I can specify which profile to use.
Python Solutions
Solution 1 - Python
I think the docs aren't wonderful at exposing how to do this. It has been a supported feature for some time, however, and there are some details in this pull request.
So there are three different ways to do this:
Option A) Create a new session with the profile
dev = boto3.session.Session(profile_name='dev')
Option B) Change the profile of the default session in code
boto3.setup_default_session(profile_name='dev')
Option C) Change the profile of the default session with an environment variable
$ AWS_PROFILE=dev ipython
>>> import boto3
>>> s3dev = boto3.resource('s3')
Solution 2 - Python
Do this to use a profile with name 'dev':
session = boto3.session.Session(profile_name='dev')
s3 = session.resource('s3')
for bucket in s3.buckets.all():
print(bucket.name)
Solution 3 - Python
This section of the boto3 documentation is helpful.
Here's what worked for me:
session = boto3.Session(profile_name='dev')
client = session.client('cloudfront')
Solution 4 - Python
Just add profile to session configuration before client call.
boto3.session.Session(profile_name='YOUR_PROFILE_NAME').client('cloudwatch')
