py-aws-sso

Simple Python library for AWS SSO credential management in local development.

About

py-aws-sso simplifies obtaining short-term credentials for CLI and Boto3 operations when using AWS SSO during local Python development.

How To Video Guide

Motivation

In our organization developing applications that interact with AWS accounts often requires managing long-term credentials. This can lead to several challenges, including:

• Security risks: Long-term credentials pose a security risk if compromised.
• Credential management overhead: Developers need to securely store and manage long-term credentials, which can be cumbersome.
• Role-switching complexity: Switching between different roles or accounts can be inconvenient with long-term credentials.

py-aws-sso addresses these challenges by providing a simple solution to obtain temporary AWS credentials during local development. By leveraging temporary credentials, developers can:

• Enhance security: Mitigate the risks associated with long-term credential leaks.
• Simplify credential management: Eliminate the need to store and manage long-term credentials locally.
• Effortlessly switch roles: Easily switch between different roles and accounts within their development workflow.

This simple solution to this problem but piggy backing on AWS CLI v2 tool.

How it works

py-aws-sso simplifies obtaining temporary credentials by leveraging the AWS CLI v2 tool. It uses the existing AWS CLI configuration, and uses boto3 library to retrieve temporary credentials for the specified profile. If you haven't already established an SSO login session, py-aws-sso will automatically trigger one for you.

Prerequisites

This Python 3 module requires a working installation of the [AWS CLI v2](https://docs.aws.amazon. com/cli/latest/userguide/install-cliv2.html) and the boto3 library

Setting Up

1. Install and Configure AWS CLI v2: Follow the official documentation @ https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-sso.html to install and configure AWS CLI v2 with your SSO profiles. For quick video guide see: How to configure AWS CLI so that we can use AWS SSO

2. Include py-aws-sso: Install py-aws-sso.

pip install py-aws-sso

--or--

pdm add py-aws-sso

3. Run Your Project:
   • Create a local_run.py file to execute your project using Python.
   • Import set_aws_creds from the awssso module.
   • Call set_aws_creds with these arguments:
     • profile_name (string): The name of the AWS CLI profile to use.
     • verbose (boolean, optional): Set to True to print verbose messages (defaults to False).

Inspiration:

This project is inspired by the aws-sso-credentials project. However, it caters specifically to Python developers and focuses on local development workflows.

Example

from awssso import set_aws_creds

# Assuming your AWS profile name is "my-sso-profile"
set_aws_creds(profile_name="my-sso-profile", verbose=True)

# Now you can use boto3 with the temporary credentials
import boto3

s3_client = boto3.client("s3")
response = s3_client.list_buckets()
print(response)
