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

    For CentOS or similar,
        yum install gcc make fuse-devel curl-devel libxml2-devel openssl-devel

    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:

    The following settings can be defined in the file ~/.cloudfuse:
        username=[Account username for authentication, required]
        api_key=[API key for authentication with Rackspace]
        tenant=[Tenant for authentication with Openstack]
        password=[Authentication password with Openstack]
        authurl=[Authentication url, defaults to Rackspace's cloud]
        region=[Regional endpoint to use]
        use_snet=[True to use Rackspace ServiceNet for connections]
        cache_timeout=[Seconds for directory caching, default 600]
        verify_ssl=[False to disable SSL cert verification]

    For authenticating with Rackspace's cloud, at minimum "username" and
    "api_key" must be set.

    For authenticating with Keystone, "username", "password", "tenant", and
    "authurl" should probably be defined.

    These settings can also be specified 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

    It also inherits a number of command-line arguments and mount options from
    the Fuse framework.  The "-h" argument should provide a summary.


EXAMPLE:

    A typical ~/.cloudfuse configuration file for use with Rackspace:
        username=demo
        api_key=643afce8b5187d40ba15e4827384fc5b
        
        # if no region is selected, it will use your default region.
        #   region=DFW
        
        # if connecting within a Rackspace datacenter, ServiceNet can be
        # used to avoid bandwidth charges.
        #   use_snet=true

    A typical ~/.cloudfuse configuration file for use with OpenStack:
        username=demo
        tenant=demo
        password=supersecret
        authurl=http://10.10.0.1:5000/v2.0


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.
