Support neutron QoS in heat

https://blueprints.launchpad.net/heat/+spec/support-neutron-qos

Provides support for neutron QoS feature.

Problem description

https://blueprints.launchpad.net/neutron/+spec/quantum-qos-api

After the above blueprint, neutron supports an api extension for QoS, and now provides support for attaching/detaching QoS policy to port and network resources(with create and update). There are two data models QoSPolicy and QoSRule, with a relationship: QoSRule(s)->QoSPolicy -> Port/Network. For now, neutron has implemented one rule type, QoSBandwidthLimitRule that provides bandwidth limit on the instance egress traffic.

Administrator of a cloud may want to offer different service levels based on the available network resources with heat, so this blueprint will provide support for neutron resource QoS in heat, based on above neutron resources for QoS.

Proposed change

  1. Add following Resources under resources/openstack/neutron/
  • OS::Neutron::QoSPolicy

    Properties:

    • name:
      • type: String
      • required: True
      • description: The name of QoS policy
      • update_allowed: True
    • description:
      • type: String
      • required: False
      • description: The description of QoS policy
      • update_allowed: True
    • shared:
      • type: Boolean
      • required: False
      • description: Whether this QoS policy be shared to other tenants
      • update_allowed: True
      • default: False
    • tenant_id:
      • type: String
      • required: False
      • description: The owner tenant ID of this QoS policy
      • update_allowed: False

    Attributes:

    • rules:
      • type: List
      • description: A list of all rules for the QoS policy
  • OS::Neutron::QoSBandwidthLimitRule

    Properties:

    • policy:
      • type: String
      • required: True
      • description: ID or name of the QoS policy
      • update_allowed: False
      • constraints: Custom Constrain ‘neutron.qos_policy’
    • max-kbps:
      • type: Integer
      • required: True
      • description: Max bandwidth in kbps
      • update_allowed: True
      • constraints: Range(min=0)
    • max-burst-kbps:
      • type: Integer
      • required: False
      • description: Max burst bandwidth in kbps
      • update_allowed: True
      • default: 0
      • constraints: Range(min=0)

2. Add ‘qos_policy’ property for OS::Neutron::Port and OS::Neutron::Network resources:

  • qos_policy:
    • type: String
    • required: False
    • description: The name or ID of QoS policy to attach
    • update_allowed: True
    • constraints: Custom Constrain ‘neutron.qos_policy’
