Subject [ANNOUNCE] Apache Deltacloud 0.4.0 (incubating)
Date Wed, 14 Sep 2011 22:49:13 GMT
I am pleased to announce the availability of Apache Deltacloud 0.4.0.

Apache Deltacloud is a RESTful cloud abstraction API. The release
consists both of the API server and a Ruby client.

The release can be found at Gems and RPM's
for Fedora will become available shortly.

Many thanks to all those who contributed patches, reported bugs, and
asked for features. It's great to see that the list of committers and
patch contributors is steadily increasing.

Overview of the changes for this release:

  * deltacloudd: new option --drivers to list all drivers; new option
    --daemon to daemonize the server
  * deltacloudd: new options --ssl, --ssl-key and --ssl-cert to
    enable HTTPS support
  * API entrypoint reports features in JSON
  * unify response behavior: any operation returning a 201 Created also
    sets the Location header to point to the new resource; ensure the
    status for an operation is the same regardless of output format
  * Add type to public addresses; type can be one of 'ipv4', 'mac', 'vnc',
    and 'hostname'
  * Complete overhaul of the HTML UI, now uses jquery-mobile
  * Response status for attach/detach storage is now 202 (instead of 302)
  * Response status for get/set blob metadata is 204 No Content
  * Response status for (un)register with load balancer is 204 No Content
  * The user_name feature now reports the permissible length of the name
    as the 'max_length' constraint
  * Add Date header to responses as per RFC 2616
  * New collection 'firewalls' for managing sets of firewalling rules
  * split server/config/drivers.yaml into individual files so each driver
    can be packaged separately; gives deployers better choice of what
    drivers they want enabled
  * Numerous bug fixes and improvements to the test suite
  * Drivers
    + Condor
      - new driver to run a simple cloud based on the Condor grid scheduler
    + EC2
      - Fix bug in reboot instance so that the details returned are those
        of the stopped instance, not some random instance
      - Support getting and updating blob metadata
      - support destroying images
      - support firewalls (security groups)
      - do not support user_name anymore; instance tagging is too fragile
        in EC2 to be used reliably for this
      - do not support registering an instance with a load balancer upon
        creation anymore
      - stream blob PUT to backend (requires thin)
      - support attaching EBS snapshot to instance upon creation (feature
      - support elastic IP's
    + Eucalyptus
      - support firewalls (security groups)
      - support elastic IP's
    + Gogrid
      - when retrieving single realm, make sure we return the right one
      - correctly capture load_balancer params
      - report a listener if load_balancer has no instances
    + Mock
      - support destroying images
      - refactored driver to fix various bugs, and to make it an easier
        to understand example of how a driver works
    + Rackspace
      - support destroying images
      - stream blob PUT to backend (requires thin)
    + RHEV-M
      - support creating and destroying images
      - report VNC address of instances
      - can use Audrey's confserver to fetch IP of an instance
    + vSphere
      - turns a VMWare vSphere installation into a cloud
      - driver stateless, state is stored in vSphere's data store in
        'deltacloud' folder
      - images are template VM's
      - single HWP, whose max_cpu and max_memory are based on available
        cpus and memory across all vSphere hosts
      - support data injection via user_data and user_iso (upload entire
        ISO image) For both, instance gets virtual CD-ROM with injected

  * make authentication info for instances available
  * retrieve type and address for public addresses of an instance
  * deltacloudc: allow specifying bucket location when creating a bucket

  * Major rewrite of REST API docs, covers the entire API now
  * Add libdeltacloud API docs
  * Add ASF incubator logo and disclaimer to project site
