High level tools to manage an AWS infrastructure
Project description
AWSTOOLS is a Python package that provide modules and commands to manage an infrastructure on Amazon Web Services.
Awstools is driven by a set of conventions and choices to makes system operations simple to the most. Awstools is mainly focused on managing multiple isolated social/web/mobile architectures.
Main conventions and choices:
Using one of the Amazon Web Service is better than a custom solution
Operation system: Ubuntu LTS or newer
Configuration system: Puppet
At the moment awstools supports:
-
ApplicationSettings (awstools.applications) Describe your application by declaring a set of Pool per Environment
cfn: List, Create, Update, Delete, Inspect Manage your AWS resources based on ApplicationSettings and cloudformation templates
-
ec2ssh: Connect to one or multiple instances in a handy way
Installation
- Python requirements:
argh
boto
PyYaml
Configuration
You must have a valid boto credentials provider to use the awstools. See the `Boto tutorial <http://docs.pythonboto.org/en/latest/boto_config_tut.html>`_.
