assume-aws-role

Work with multiple AWS accounts more easily.

If you currently manage multiple AWS accounts and use role switching to do work in them, this is the tool for you!

Requirements

Usage

First, you need to install the tool from NPM:

npm install -g assume-aws-role

Next, you need to add a role that you'd like to assume. As an example, lets say I wanted to add the Administrator role for my sandbox account with MFA required:

assume-aws-role add sandbox \
  "arn:aws:iam::123456789012:role/Administrator" \
  "arn:aws:iam::109876543210:mfa/jbuck"

Now you can assume that role we just added:

assume-aws-role sandbox 123456

Now you've got a shell with your temporary security credentials in the environment:

(assume-aws-role sandbox)$

You can also add roles without MFA devices:

assume-aws-role add sandbox \
  "arn:aws:iam::123456789012:role/Administrator"

You can list all the defined roles with a single command:

assume-aws-role list

You can delete a defined alias with a single command:

assume-aws-role delete <alias>

How does it work?

Any roles you add are stored in ~/.assume-aws-role/config. It's optional but highly recommended that you use a MFA device.

assume-aws-role uses the STS:AssumeRole API to assume the role you specified.

After receiving valid credentials assume-aws-role will spawn the shell specified in $SHELL with the environment modified to include AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and AWS_SESSION_TOKEN. The environment also includes an overridden PS1 with a minimal custom prompt, and ASSUME_AWS_ROLE with the role so you can fully customize the PS1 prompt by yourself.
