Create an Image from within an Instance
=======================================

General Overview
----------------

This application has been created to work with Openstack if using the XenServer Hypervisor. At this time the code base supports Openstack as a whole, however the application has only been tested on Rackspace Cloud Servers. 

Overview:
---------

*XenOsImager* will create an image from information obtained from within the instance. The application will look at the "*xenstore*" data to determine the UUID of the instance, and the region. The user is only required to input their OpenStack API Credentials into a simple configuration file. These credentials are only used to make API calls for image creation.

Simply the application will allow you to create images of instances as a simple automation task; CRON job, on demand, or anythine else you can think of.


Prerequisites :
  * Python => 2.6 but < 3.0
  * python-setuptools


Installation is simple :

  from Python.org, IE "pip"


    .. code-block:: bash

        pip install xenosimager


  from Github, which is Trunk.


    .. code-block:: bash

        git clone git://github.com/cloudnull/transporter.git
        cd transporter
        python setup.py install


Setup is Simple too edit the file "/etc/xenosimager/config.cfg" :

    .. code-block:: bash

        vi /etc/xenosimager/config.cfg


In the previous file, add your credentials. If you feel so inclined, you can also add your mail relay information and the system will send you a message when the images are created or if there are overall issues. 


Available Options in the config file or on the CLI : 


Required Variables from CLI
---------------------------

 - ``system-config`` | Where your config file exists
 - ``image-name`` | the name of the image


OpenStack Variables
-------------------

 - ``os_user`` | YOU
 - ``os_apikey`` | SuperSecretInformation
 - ``os_auth_url`` | Authentication URL
 - ``os_rax_auth`` | A-LOCATION
 - ``os_verbose`` | True or False
 - ``os_password`` | SuperSecretInformation
 - ``os_tenant`` | UsernameGenerally
 - ``os_region`` | WhereIsThisInstance
 - ``os_version`` | v2.0


Mail Variables
--------------

 - ``mail-main-contact`` | WhoReadsEmail
 - ``mail_debug`` | True or False
 - ``mail_url`` | AURL
 - ``mail_user`` | Username
 - ``mail_password`` | Password
 - ``mail_cert`` | /location/cert
 - ``mail_key`` | KeyForCert
 - ``mail_tls`` | True or False
 - ``mail_port`` | Port Number


How to use this tool
--------------------

Application is simple to use. Simply follow this command and add your own custom name to the end.

    .. code-block:: bash

        xenosimager --system-config /etc/xenosimager/config.cfg --image-name $NAME_OF_THE_IMAGE


Logs are created for all interaction of the imager, and can be found here :

    .. code-block:: bash

        /var/log/xenosimager.log


For automated image create please have a look at the example.cron.txt file, which is where you can find cron job examples, but with little to no ingenuity I am sure you could figure out other methods for automated command execution.
