This is a couple of scripts that show up how the RackSpace Cloud Servers API works. It is by design keep simple to be easy to peek or to look at.

REQUIREMENT ==========

These demos needs the python-cloudservers library, unfortunately the upstream version from here :

http://packages.python.org/python-cloudservers/

Doesn't support different auth server, so the easiest way is to download my forked version :

https://github.com/chmouel/python-cloudservers/tarball/master

and install it in your PYTHONPATH (usually /usr/local/lib/python${PYTHON_VERSION}/site-packages/ )

You would need to have a file config in the root directory of this software containing information about your Cloud containing :

export RCLOUD_DATACENTER="UK"

export US_RCLOUD_USER="" export US_RCLOUD_KEY="" export US_RCLOUD_AURL="https://auth.api.rackspacecloud.com/v1.0"

export UK_RCLOUD_USER="" export UK_RCLOUD_KEY="" export UK_RCLOUD_AURL="https://lon.auth.api.rackspacecloud.com/v1.0"

You don't have to have two different account but make sure RCLOUD_DATACENTER goes to the right ones.

The python directory has all the python scripts which is the guts to interact with cloudservers.

This is the description of what the script does :

• backup.py

  Allow you to choose a image to backup into RackSpace Cloud Files (by default on RackSpace UK Cloud).

• create.py

  Will ask you to create a new image into the cloud and will launch a script on it with some basic configurations.

• delete-images.py

  Give you the opportunity to delete your stored images (or backups).

• delete-servers.py

  Give you the opportunity to delete your stored servers.

• generatepassword.py

  A simple script that output a nice generated random password (human readable).

• list-images.py

  Will list your images available (not the system ones only yours).

• list-servers.py

  Will list your servers in your cloud.

APPLICATIONS ===========

Applications are different roles for showcasing the demos. As a start we have the guestbook application which create two servers a WEB and DB install a guestbook apps on it configure and secure it.

The purpose of this demo is to have it to setup a periodic task (cron) to backup the VM at certain time and automatically start it again at another time.

In the guestbook directory we have :

• create.sh

  Will create a web and a db server copy your SSH id_rsa key ~/.ssh/id_rsa for SSH access and launch the scripts setup-web-guestbook.sh and setup-db.sh from your scripts directory. And configure neworking with the adjust-db-networking.sh and adjust-web-networking.sh

• backup.sh

  Would backup those images in the cloud and deleting the server

• restore.sh

  Would backup the images and adjust the networking on the server with the adjust-db or web networking scripts.

• cron.sh

  This is the cron that takes care to check the files /tmp/guestbook-files-backup or /tmo/guestbook-files-restore for the time when the backup.sh and restore.sh needs to be started. You would need to configure your cron to launch it like this entry :

  /1 * * * /home/russell/api-demo/guestbook/cron.sh backup &>/tmp/backup-log.txt /1 * * * /home/russell/api-demo/guestbook/cron.sh restore &>/tmp/restore-log.txt

• setup-cron.sh

  Simple script that ask you for the time to backup and restore and dump the time in the /tmp/guestbook-file-{restore,backup}
