资源属性的Openstack HEAT条件

“条件(..)可以与资源部分(..)中的资源和资源属性相关联” -官方openstack的文档说我可以做到这一点。但是所附示例并未包含带有“资源属性”的示例。

我有一个示例,当用户可以将参数设置为“不创建端口2”并且不附加端口2(因为端口2不存在)时:

parameters:
  global_port2_create:
    description: Do you want eth1 (port2)
    type: string
    default: true

conditions:
  create_port2: {equals : [{get_param: global_port2_create}, "true"]}

resources:
  node_port1:
    type: OS::Neutron::Port
    properties:
      network_id: {get_param: global_port1_net_id }
      fixed_ips:
        - subnet_id: {get_param: global_port1_net_id }
        - ip_address: {get_param: node_port1_ip }
      security_groups: {get_param: global_port1_security_groups_ids}
  node_port2:
    type: OS::Neutron::Port
    condition: create_port2
    properties:
      network_id: {get_param: global_port_net_id }
      fixed_ips:
        - subnet_id: {get_param: global_port2_net_id }
        - ip_address: {get_param: node5_port2_ip }
      security_groups: {get_param: global_port2_security_groups_ids}
  node5_server:
    type: OS::Nova::Server
    depends_on: [ node5_port1, node5_port2 ]
    properties:
      name: some_name
      image: { get_param: global_image }
      availability_zone: some_az
      networks:
        - port: { get_resource: node5_port1 }
        - port: { get_resource: node5_port2 }  #How to use a condition here?

我知道,我可以同时使用两个端口进行ResourceGroup并对其进行迭代,但是我不希望这种解决方案。 也许是这样吗?

      networks:
        - port: { get_resource: node5_port1 }
        - port:
          condition: create_port2
          get_resource: node5_port2

任何人都知道如何实现这一目标吗?

我有一个类似的用例,找到了解决方案。但是,如果仍然值得关注,请告别可读性:

      networks: {if: [ "create_port2", [port: { get_resource: node5_port1 }, port: { get_resource: node5_port2 }], [port: { get_resource: node5_port1 }]}

您也可以写:

      networks:
        if: 
        - "create_port2"
        - [port: { get_resource: node5_port1 }, port: { get_resource: node5_port2 }]
        - [port: { get_resource: node5_port1 }]

甚至:

      networks:
        if: 
        - "create_port2"
        - - port: { get_resource: node5_port1 }
          - port: { get_resource: node5_port2 }
        - - port: { get_resource: node5_port1 }

选择你的毒药!
