Transporter

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"

pip install xenosimager

from Github, which is Trunk.

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" :

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

How to use this tool

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

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 :

/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.
