Cloudfuse is a FUSE application which provides access to Rackspace's
Cloud Files (or any installation of Swift).
Cloud Files is a remote storage system which is similar in principle to
Amazon S3. It provides a simple RESTful interface to storing and retrieving
objects.

Swift, the software behind Cloud Files, has been open-sourced as part of the
OpenStack project.

BUILDING:
You'll need libcurl, fuse, libssl, and libxml2 (and probably their dev
packages) installed to build it. From a base Debian or Ubuntu install,
this should get you to a point you can build and run it:
apt-get install build-essential libcurl4-openssl-dev libxml2-dev \
libssl-dev libfuse-dev
Cloudfuse is built and installed like any other autoconf configured code.
Normally,
./configure
make
sudo make install
But I'm no autoconf wizard, and there may be dragons lurking there.
USE:
Your Rackspace Cloud username and API key can be placed in a file
named $HOME/.cloudfuse:
username=[username]
api_key=[api key]
Or as mount options on the command line:
cloudfuse -o username=redbo,api_key=713aa... mountpoint/
Or as mount options in /etc/fstab:
cloudfuse /mnt/cloudfiles fuse username=redbo,api_key=713aa...,user 0 0
The following options are... optional:
use_snet=[True to use servicenet for connections]
cache_timeout=[seconds for directory caching, default 600]
authurl=[authentication url - connect to non-Rackspace (swift) cluster]
use_openstack=[True if using OpenStack Keystone]
tenant=[Tenant for authentication with Keystone]
It also inherits a number of command-line arguments and mount options from
the Fuse framework. The "-h" argument should provide a summary.
Your OS user will need access to the "fuse" group. This can probably be
accomplished with:
sudo usermod -a -G fuse [username]
EXAMPLE:
A typical .cloudfuse configuration file for use with OpenStack Essex:
username=demo
tenant=demo
api_key=supersecret
authurl=http://10.10.0.1:5000/v2.0/tokens
use_openstack=true
BUGS/SHORTCOMINGS:
* rename() doesn't work on directories (and probably never will).
* When reading and writing files, it buffers them in a local temp file.
* It keeps an in-memory cache of the directory structure, so it may not be
usable for large file systems. Also, files added by other applications
will not show up until the cache expires.
* The root directory can only contain directories, as these are mapped to
containers in cloudfiles.
* Directory entries are created as empty files with the content-type
"application/directory".
* Cloud Files limits container and object listings to 10,000 items.
cloudfuse won't list more than that many files in a single directory.
