openstack heat：根据条件将端口添加到实例

Question

仅当名称为 zee_1 时，我才想将端口添加到实例

模板文件：

resources:

  vm_port_routable:
    type: OS::Neutron::Port
    properties:
      network: { get_param: abc_routable_net }
      name:
        str_replace:
          template: $stack_$name_routable_port
          params:
            $stack: { get_param: stack }
            $name: { get_param: vm_name }
      security_groups: [{ get_param: security_group }]
      fixed_ips:
        - ip_address: { get_param: port_ip_routable }

  test_vm_port_routable:
    type: OS::Neutron::Port
    properties:

      network: { get_param: test_zee_routable_net }
      name:
        str_replace:
          template: $stack_$name_routable_port
          params:
            $stack: { get_param: stack }
            $name: { get_param: vm_name }
      security_groups: [{ get_param: security_group }]
      fixed_ips:
        - ip_address: { get_param: test_port_ip_routable }

      zee_server:
        type: OS::Nova::Server
        properties:
          block_device_mapping_v2:
            - boot_index: 0
              delete_on_termination: false
              volume_id: { get_resource: root_volume }
              device_name: vda
              device_type: disk
            - boot_index: -1
              delete_on_termination: false
              volume_id: { get_param: backup_volume }
              device_name: vdc
              device_type: disk
          flavor: { get_param: flavor }
          key_name: { get_param: ssh_keypair }
          name: { get_param: vm_name }

          networks:
            - port: { get_resource: vm_port_routable }
            - port: { get_resource: test_vm_port_routable }

仅当名称为 zee_1 时，我才想添加端口“test_vm_port_route”....

我尝试了以下条件，但它给出了错误：错误：模板部分无效：条件

conditions:
       create_prod_res: { equal: [{get_param: "vm_name"},"zee_1"]}
resources:

  vm_port_routable:
    type: OS::Neutron::Port
    properties:
      network: { get_param: abc_routable_net }

        str_replace:
          template: $stack_$name_routable_port
          params:
            $stack: { get_param: stack }
            $name: { get_param: vm_name }
      security_groups: [{ get_param: security_group }]
      fixed_ips:
        - ip_address: { get_param: port_ip_routable }

  test_vm_port_routable:
    type: OS::Neutron::Port
    properties:

      network: { get_param: test_zee_routable_net }
      name:
        str_replace:
          template: $stack_$name_routable_port
          params:
            $stack: { get_param: stack }
            $name: { get_param: vm_name }
      security_groups: [{ get_param: security_group }]
      fixed_ips:
        - ip_address: { get_param: test_port_ip_routable }

      zee_server:

              delete_on_termination: false
              volume_id: { get_resource: root_volume }
              device_name: vda
              device_type: disk
            - boot_index: -1
              delete_on_termination: false
              volume_id: { get_param: backup_volume }
              device_name: vdc
              device_type: disk
          flavor: { get_param: flavor }
          key_name: { get_param: ssh_keypair }
          name: { get_param: vm_name }
          condition:create_prod_res  
          networks:
            - port: { get_resource: vm_port_routable }
            - port: { get_resource: test_vm_port_routable }

以上对模板的更改失败了
有人可以帮助我吗.....

如果您阅读 specification，您会注意到对 conditions 部分的支持仅在 Newton 中添加。所以你需要：

heat_template_version: newton

或者：

heat_template_version: 2016-10-14

或以后版本的等价物。如果您运行的是早于 Newton 的 openstack 版本，您将无法使用此功能。
