Implement Sahara image resource

https://blueprints.launchpad.net/heat/+spec/sahara-image

Add support for Sahara image resource which will allow to register images in sahara and add tags.

Problem description

Before creating a cluster we have to register an image in the sahara image registry and add tags. Currently we can do this using sahara CLI or UI and then create a stack with sahara resources (node group template, cluster template and cluster). It would be more comfortable to register/unregister an image using the same template when a stack is created/deleted.

Proposed change

Implement OS::Sahara::ImageRegistry resource:

Properties:

  • image (required) - image id to register
  • username (required, update allowed) - username of privileged user in the image
  • description (optional, update allowed) - description of the image
  • tags (optional, update allowed) - tags to add to the image

Usage example:

glance-image:
  type: OS::Glance::Image
  properties:
    name: sahara-icehouse-vanilla-1.2.1-ubuntu-13.10
    disk_format: qcow2
    container_format: bare
    location: http://sahara-files.mirantis.com/sahara-icehouse-vanilla-1.2.1-ubuntu-13.10.qcow2

sahara-image:
  type: OS::Sahara::ImageRegistry
  properties:
    image: {get_resource: glance-image}
    username: ubuntu
    tags: ['vanilla', '1.2.1']
