Extending SaltStack

Overview of this book

Salt already ships with a very powerful set of tools, but that doesn't mean that they all suit your needs perfectly. By adding your own modules and enhancing existing ones, you can bring the functionality that you need to increase your productivity. Extending SaltStack follows a tutorial-based approach to explain different types of modules, from fundamentals to complete and full-functioning modules. Starting with the Loader system that drives Salt, this book will guide you through the most common types of modules. First you will learn how to write execution modules. Then you will extend the configuration using the grain, pillar, and SDB modules. Next up will be state modules and then the renderers that can be used with them. This will be followed with returner and output modules, which increase your options to manage return data. After that, there will be modules for external file servers, clouds, beacons, and finally external authentication and wheel modules to manage the master. With this guide in hand, you will be prepared to create, troubleshoot, and manage the most common types of Salt modules and take your infrastructure to new heights!

The final cloud module

When we have finished, the final cloud module will look like this:

Generic Salt Cloud module

This module is not designed for any specific cloud provider, but is generic
enough that only minimal changes may be required for some providers.

This file should be saved as salt/cloud/clouds/

Set up the cloud configuration at ``/etc/salt/cloud.providers`` or

.. code-block:: yaml

      driver: generic
      # The login user
      user: larry
      # The user's password
      password: 123pass
import json
import salt.utils.http
import salt.config as config
from salt.exceptions import SaltCloudSystemExit

__virtualname__ = 'generic'

def __virtual__():
    Check for cloud configs
    if get_configured_provider() is False:
        return False

    return __virtualname__

def get_configured_provider():
    Make sure configuration is correct...
