aws-tools

This package provides tools for AWS platform, such as:

• switching between multiple accounts
• renewing API access keys

and others.

The main reason why aws-tools came to be, was using awscli with different access keys in the secure and easy way.

How it works

Switching between AWS accounts:

$ awsenv test
<test> $ aws s3 ls
...list of S3 objects on TEST environment...

### Explanation:
### <test> $ env | grep AWS
### AWS_SECRET_ACCESS_KEY=w0bM0rucARITPOUpcyAaX3iI9lGjJo7g8UUCUxIv
### AWS_ACCESS_KEY_ID=AKIAJPVK7VGH6CBZT5EQ
### AWS_ENV=test

<test> $ awsenv prod
<prod> $ aws s3 ls
...list of S3 objects on PROD environment...

### Explanation:
### <prod> $ env | grep AWS
### AWS_SECRET_ACCESS_KEY=P8crbSIvQ/Au0jfnW8XER9eJKxpQdYqpRVz5QxKo
### AWS_ACCESS_KEY_ID=AKIAJ4F26CMBPI1HF7MQ
### AWS_ENV=prod

Renewing AWS API access keys:

$ awsenv prod

### Explanation:
### <prod> $ env | grep AWS
### AWS_SECRET_ACCESS_KEY=P8crbSIvQ/Au0jfnW8XER9eJKxpQdYqpRVz5QxKo
### AWS_ACCESS_KEY_ID=AKIAJ4F26CMBPI1HF7MQ
### AWS_ENV=prod

<prod> $ awsroll prod
Rolled key for env prod: AccessKeyId=****************ZKQFQ; CreateDate=2018-11-14 13:10:04+00:00
<prod> $ awsenv prod

### Explanation:
### <prod> $ env | grep AWS
### AWS_SECRET_ACCESS_KEY=napb9J2RKzsSiTIjLRavN09qIfFzrMo7846zr2ou
### AWS_ACCESS_KEY_ID=AKIAJTGB6EFV7F4ZKQFQ
### AWS_ENV=prod

Getting started

Prerequisites:

aws-tools requires gpg (version >= 2.X) to decrypt/encrypt your AWS credentials.

Install necessary packages, and generate a new key pair:

$ sudo apt-get install gpg gpg-agent
$ gpg --gen-key

This document covers only gpg commands required to run aws-tools! If you need to use other gpg parameters, go to gpg documentation.

Configure your region using awscli if you haven't done that yet:

$ aws configure
AWS Access Key ID [None]:
AWS Secret Access Key [None]:
Default region name [None]: eu-west-1
Default output format [None]:

Do not provide any keys here!

Installation

Simply run:

$ pip install --user aws-tools

Configuration

AWS Credentials

In ~/.aws directory create temporary env.<environment>.conf file for each AWS environment.

For example, if you have 3 AWS environments: TEST, STAGE and PROD, there should be 3 config files in ~/.aws directory:

env.test.conf
env.stage.conf
env.prod.conf

Edit each file:

[default]
aws_access_key_id = <your_environment_specific_access_key_id>
aws_secret_access_key = <your_environment_specific_secret_access_key>

Encrypt each file with gpg:

$ gpg --encrypt --armor --output env.<environment>.conf.asc -r <your-gpg-user-id-name> env.<environment>.conf

and remove temporary env.*.conf files!

Run gpg -K to find out what is your <your-gpg-user-id-name>

Shell

aws-tools comes with handy command completion and bash prompt features. Simply add to your ~/.bashrc:

source $HOME/.local/bin/aws_tools_completion.bash 2>/dev/null
export PS1="\$(__awsenv_ps1 2>/dev/null)${PS1}"

SMTP credentials (optional)

This step is helpful if you want to send renewed AWS access keys to an email.

In ~/.aws directory create temporary smtp.cfg file.

Edit smtp settings:

smtplogin = <your_full_smtp_login>
smtppass = <your_password>
smtphost = <smtp_host>
smtpport = <smtp_port>

Encrypt config file with gpg:

$ gpg --encrypt --armor --output smtp.cfg.asc -r <your-gpg-user-id-name> smtp.cfg

and remove temporary smtp.cfg file!

Usage

Examples

Autocompletion:

$ awsenv<TAB><TAB>
prod stage test

Use TEST access keys:

$ awsenv test

Unset AWS access keys for current shell:

$ awsenv unset

Rotate PROD access keys:

$ awsroll prod

Rotate access keys for all environments:

$ awsroll

Rotate access keys for all environments using gpg agent, and send them to the email:

$ aws-roll-keys.py -a -e all -s <[email protected]>

Rotate access keys for TEST environment and send info to the email:

$ aws-roll-keys.py -e test -i <[email protected]>
