description: >
  This is a very simple template that illustrates the basic features
  of OS::Heat::AutoScalingGroup when the scaled resource is an
  OS::Nova::Server.  By virtue of its simplicity this example should
  be usable in many contexts.  In particular, this example does not
  require Neutron nor a load balancer nor any particular support for
  software in the VMs.  In fact, the VMs in this example do not
  actually do anything.  This example does no automatic scaling, but
  does discuss manual scaling.
  For a more complete example, see autoscaling.yaml.


parameters:
  key_name:
    type: string
    description: Name of an existing key pair to use for the instances
    constraints:
      - custom_constraint: nova.keypair
        description: Must name a public key (pair) known to Nova
  flavor:
    type: string
    description: Flavor for the instances to be created
    default: m1.small
    constraints:
      - custom_constraint: nova.flavor
        description: Must be a flavor known to Nova
  image:
    type: string
    description: >
      Name or ID of the image to use for the instances.
      You can get the default from
      http://cloud.fedoraproject.org/fedora-20.x86_64.qcow2
      There is also
      http://cloud.fedoraproject.org/fedora-20.i386.qcow2
      Any image should work since this template
      does not ask the VMs to do anything.
