The binding is pretty simple and have unfortunately no documentation (or even tests) but you can figure out most of it from here :

https://github.com/rackspace/python-clouddns/blob/master/tests/t.py

I will be very welcoming pull request that add a bit of documentation.

This make things easy to add as a dependence of your project like you can have something like this in your setup.py :

requirements = ['python-cloudfiles']

and it will automatically download it as part of the dependence with easy_install or pip.

cool kids on latest debian/ubuntu can do stuff like this (from python-stdeb package) :

pypi-install python-cloudfiles

which would automatically download the tarball from pypi and install it as a packages (like the way it should be for prod machine!)

If you have a virtualenv environment you can easily do a (needs python-pip package) :

pip -E /usr/local/myvirtualenvroot install python-cloudfiles


and magic would be done to get you on latest python-cloudfiles.

As a bonus side you can browse online the python-cloudfiles library :

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

[Update] This has been renamed back to python-cloudfiles please update your setup.py or scripts.

This is available here :

http://getlastlastfmlyrics.appspot.com/

for the scripter around you can just get (via curl or other) :

http://getlastlastfmlyrics.appspot.com/?u=username

and it will automatically display it for that username.

it seems that there is a lot of ‘solutions’ (read hack) or workaround around the web which is resumed well on this stack overflow article.

There is actually a very easy (and secure) way on Debian based systems.

- Go to your https url with Firefox
- Right Click to ‘View Page Info’
- In ‘Security’ tab you will see a button saying ‘View Certificate’
- Click now on the ‘Details’ tab
- Finally click on the ‘Export’ button which offer you to save the PEM certifcate of the website somewhere on your filesystem.

Call it my.self.signed.domain.name.pem or whatever my.self.signed.domain.name should be and put the file in /etc/ssl/certs now you just have to run the command :

sudo update-ca-certificates

and it should add your certificate to the java keystore, you can check it with the command (Enter for Password) :

keytool -list -v -keystore /etc/ssl/certs/java/cacerts

I have then started to look over Jython to see if I can interact easily with Java via Python and this was actually pretty easy, it took me less than 10mn to convert a Login/Listing-VAPPS script in Jython.

The script is attached at the end of this post (or on github gist here). Don’t forget to adjust the classpath variable mine are defined like that :

I have add that feature properly to the PHP and Python API in version 1.5.0 to add a ‘servicenet’ argument to the connection and updated the blog post here :

http://blog.chmouel.com/2009/10/14/how-to-connect-to-rackspace-cloud-files-via-servicenet/

It should give you all the information for the howto use that feature.

I have released as well a minor update in 1.5.1 to allow you to define the environment variable RACKSPACE_SERVICENET to force the use of the Rackspace ServiceNET this allow you to don’t have to modify the tools and have a clean code between prod and testing.

The first thing is to make sure with your support team if your servers are connected to ServiceNet and if you have that connection then there is a small change to do in your code.

The second thing is to use the just released 1.5.0 version on GitHUB for PHP :

http://github.com/rackspace/php-cloudfiles/tree/1.5.0

and for python :

http://github.com/rackspace/python-cloudfiles/tree/1.5.0

(you need to click on the download link at the top to download the tarball of the release).

Afer this is just a matter to set the argument servicenet=True, for example in PHP :

$user='username';
$api_key='theapi_key';
 
$auth = new CF_Authentication($user, $api_key);
$auth->authenticate();
$conn = new CF_Connection($auth, $servicenet=true);

In Python you can do like this :

username='username'
api_key='api_key'
 
cnx = cloudfiles.get_connection(username, api_key, servicenet=True)

It’s really a collection of quickly written stuff put in the same file
but at least if not useful for you it would give you an idea how the
python-cloudfiles works. It is all available here :
