The London Perl and Raku Workshop takes place on 26th Oct 2024. If your company depends on Perl, please consider sponsoring and/or attending.


WebService::Rackspace::CloudFiles - Interface to Rackspace CloudFiles service


  use WebService::Rackspace::CloudFiles;

  my $cloudfiles = WebService::Rackspace::CloudFiles->new(
      user => 'myusername',
      key  => 'mysecretkey',

  say "$object_count objects";

  my $bytes_used = $container->bytes_used;
  say "$bytes_used bytes";

  # returns a Data::Stream::Bulk object
  # as it may have to make multiple HTTP requests
  my @objects = $container->objects->all;
  foreach my $object (@objects) {
      say 'have object ' . $object->name;
      # also size, etag, content_type, last_modified

  # To create a new object
  my $xxx = $container->object( name => 'XXX' );
  $xxx->put('this is the value');

  # To set metadata of an object:
          description => 'this is a description',
          useful_number => 17
  # To create a new object with the contents of a local file
  my $yyy = $container->object( name => 'YYY', content_type => 'text/plain' );

  # To fetch metadata of an object:

  say 'metadata useful_number ' . $xxx2->object_metadata->{'useful_number'};
  # To download an object to a local file




This module was forked from Net::Mosso::CloudFiles which was written by Leon Brocard <>. However, due to Mosso changing its name to Rackspace it felt right to fork the module to a new namespace. Upgrading from Net::Mosso::CloudFiles 0.44 should only require you to rename all Net::Mosso entries to WebService::Rackspace.

This module provides a simple interface to the Rackspace Cloud Files service. "Cloud Files is reliable, scalable and affordable web-based storage for backing up and archiving all your static content". Find out more at

To use this module you will need to sign up to Rackspace Cloud Files and provide a "user" and "key". If you use this module, you will incurr costs as specified by Rackspace. Please check the costs. If you use this module with your user and key you will be responsible for these costs.

I highly recommend reading all about Cloud Files, but in a nutshell data is stored in objects. Objects are referenced by names and objects are stored in containers.



The constructor logs you into Cloud Files:

  my $cloudfiles = WebService::Rackspace::CloudFiles->new(
      user => 'myusername',
      key  => 'mysecretkey',

A location for the Cloud Files can now be specified. Valid locations are currently usa and uk, the default location is usa

  my $cloudfiles = WebService::Rackspace::CloudFiles->new(
      user => 'myusername',
      key  => 'mysecretkey',
      location  => 'uk',


List all the containers and return them as WebService::Rackspace::CloudFiles::Container objects:

  my @containers = $cloudfiles->containers;


Create a new container and return it as a WebService::Rackspace::CloudFiles::Container object:

  my $container = $cloudfiles->create_container(name => 'testing');


Use an existing container and return it as a WebService::Rackspace::CloudFiles::Container object:

  my $existing_container = $cloudfiles->container(name => 'testing');


Returns the total amount of bytes used in your Cloud Files account:

  my $total_bytes_used = $cloudfiles->total_bytes_used;


Testing CloudFiles is a tricky thing. Rackspace charges you a bit of money each time you use their service. And yes, testing counts as using. Because of this, this module's test suite skips testing unless you set the following three environment variables, along the lines of:



WebService::Rackspace::CloudFiles::Container, WebService::Rackspace::CloudFiles::Object.
