awstools 0.3.6

High level tools to manage an AWS infrastructure

Latest Version: 0.3.10

=====================================
AWSTOOLS - high level tools for AWS
=====================================

AWSTOOLS is a Python package that provide modules and commands to manage an
infrastructure on `Amazon Web Services <http: aws.amazon.com="">`_.

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 <http: puppetlabs.com="">`_


At the moment awstools supports:

- `CloudFormation <http: aws.amazon.com="" cloudformation="">`_

- **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

- `EC2 <http: aws.amazon.com="" ec2="">`_

- **ec2ssh**:
Connect to one or multiple instances in a handy way

- **awstools.fabric.populate_roledefs**:
Populate Fabric roles with EC2 instances using the tags.
fab -R App-Role cmd_run_on_all_app-role-*_instances



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="">`_.

- A **configuration file** is searched in this order:

1. <specified by="" --config="">
2. ./awstools.cfg
3. ~/.awstools.cfg
4. /etc/awstools.cfg

- An application settings file is searched in this order:

1. specified by --settings
2. specified by awstools configuration file

The application *gmail* has a production, a staging and a test environment.
An environment is defined by two pools: *storage* and *frontweb*.
However in test you mock the storage and don't need a *storage* pool.
All those settings will be available for the CloudFormation templates.
