As numerous companies are still running Kilo based OpenStacks, we believe Freezer needs support from that version onward. For that reason we are still catching up with OpenStack's release cycle:

  • Kilo will be tagged on 13/11/2015
  • Liberty will be tagged on 18/12/2015 latest
  • Work on Mitaka will start after that date


  • Spliting the freezer-scheduler into: [mitaka]
    • freezer-scheduler: daemon only that schedules backup/restore jobs using the freezer-agent.
    • python-freezerclient: api client used for job management.

Openstack Integration

  • freezer-api should use oslo.logging and oslo.config [liberty]
  • freezer-scheduler should use oslo.logging and oslo.config [mitaka]
  • freezer-agent should use oslo.logging and oslo.config [mitaka]
  • python-freezerclient should use cliff [mitaka]
  • Move to Tempest for integration test [mitaka]
  • Oslo.policy integration
