About

AWS provides a mechanism for temporarily assuming another role within their API system. While it is not a technically hard process it can be convoluted and hard to understand. This document aims to both make it easier to follow along with as well as give an in depth explanation of some of the underpinnings of the Bourne Again Shell (aka BASH) which can make this easier to utilize on a day to day basis.

Explanation

Below is an overexplained version of the following process:

1. Using credentials stored in ~/.aws/credentials as a "profile" which are then understood by the AWS command line tools
2. Using those AWS credentials, temporarily assume a role using the AWS Security Token Service (STS) to get temporary

Whether you're trying to give back to the open source community or collaborating on your own projects, knowing how to properly fork and generate pull requests is essential. Unfortunately, it's quite easy to make mistakes or not know what you should do when you're initially learning the process. I know that I certainly had considerable initial trouble with it, and I found a lot of the information on GitHub and around the internet to be rather piecemeal and incomplete - part of the process described here, another there, common hangups in a different place, and so on.

In an attempt to coallate this information for myself and others, this short tutorial is what I've found to be fairly standard procedure for creating a fork, doing your work, issuing a pull request, and merging that pull request back into the original project.

Creating a Fork

Just head over to the GitHub page and click the "Fork" button. It's just that simple. Once you've done that, you can use your favorite git client to clone your repo or j
