awsudo

A sudo-like tool to configure AWS environment variables and call programs

This script is useful for programs like Terraform, which doesn't support MFA when assuming roles.

Installation

python3 -m pip install awsudo-py

Usage

$ awsudo -p administrator@staging terraform apply

$ awsudo -p administrator@staging env | grep AWS
AWS_ACCESS_KEY_ID=AKIAIXMBKCITA257EHIQ
AWS_SECRET_ACCESS_KEY=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

usage: awsudo [-h] [-p PROFILE] PROG [ARG [ARG ...]]

Set environment variables using profile

positional arguments:
  PROG                  executable to run
  ARG                   args to run with program

optional arguments:
  -h, --help            show this help message and exit
  -p PROFILE, --profile PROFILE
                        AWS Profile to assume

Prior Art

There are a lot of similar programs to this one. I believe makethunder/awsudo and electronicarts/awsudo are the best alternatives. The only problems with makethunder/awsudo are that it isn't published on pypi and that it doesn't use the newest api for caching sessions. electronicarts/awsudo has all of the features, but it uses an internal session cache, instead of sharing with awscli. If you need SAML support though, the internal cache is a necessary compromise, so this package is great in that case.

project	awscli profiles	session caching	SAML	language	published
this project	yes	yes	no	python3.6	pypi
makethunder/awsudo	yes	yes*	no	python	github
electronicarts/awsudo	yes	yes⦿	yes	ruby	rubygems
pmuller/awsudo	yes	no	no	python2.7, python3.5	pypi
ingenieux/awsudo	no	no	no	golang	no
meltwater/awsudo	yes	yes	no	bash, node	npm, dockerhub

* supports session caching through older technique using awscli as a dependency

⦿ uses a daemon to cache sessions internally
