在 CloudFormation 中的多个 LoadBalancer 后面添加实例？

Question

我正在尝试找出一种将 ec2 节点添加到两个负载平衡器的方法，但我没有找到一种合理的方法来执行此操作。我认为下面的代码可以让我这样做，但没有得到我预期的结果

请注意，此代码已高度精简，仅显示 LB 部分。

{
  "AWSTemplateFormatVersion": "2010-09-09",
  "Description": " App Demo / Jd / 01042016",
  "Parameters": {
    "LoadBalancers": {
      "Description": "Please refer the LoadBalancerNames which you want the instances to be registered to",
      "Type": "List<AWS::EC2::LoadBalancers::LoadBalancerNames>",
      "Default": "web-app-demo-ext,web-api-demo-ext"
    }
  },
  "Resources": {
    "AppAutoScalingGroup": {
      "Type": "AWS::AutoScaling::AutoScalingGroup",
      "Properties": {
        "AvailabilityZones": {
          "Ref": "AZs"
        },
        "LoadBalancerNames": [{
          "Ref": "LoadBalancers"
        }]
      }
    }
  }
}

我希望看到一个可以添加多个 LB 的列表，但我看到的是一个普通的输入框（字符串）

添加带有一些 firebug hackery 的图像....

预期结果

实际发生了什么

更新

经过 Cloud Designer 的胡编乱造，我认为 "Type": "List<AWS::EC2::LoadBalancers::LoadBalancerNames>" 是不正确的，应该是 "Type": "List<AWS::ElasticLoadBalancing::LoadBalancer>"

虽然这仍然没有作为列表传播

想通了。您将需要多个参考。原因是 "LoadBalancerNames" 键可以有多个引用，像这样："LoadBalancerNames": { "Foo", "Bar" }

真的希望这对其他人有帮助，因为它让我挠了挠头好几天:)

{
  ................
  "Parameters": {
    .......
    "LoadBalancerApp": {
      "Description": "Please refer the LoadBalancerNames (APP) which you want the instances to be registered to",
      "Type": "String",
      "Default": "web-app-demo-ext"
    },
    "LoadBalancerApi": {
      "Description": "Please refer the LoadBalancerNames (API) which you want the instances to be registered to",
      "Type": "String",
      "Default": "web-api-demo-ext"
    },
    .......
  },
  "Resources": {
    ........
    "AppnameAutoScalingGroup": {
      "Type": "AWS::AutoScaling::AutoScalingGroup",
      "Properties": {
        "AvailabilityZones": {
          "Ref": "AZs"
        },
        "LaunchConfigurationName": {
          "Ref": "AppnameLaunchConfig"
        },
        "LoadBalancerNames": [{
          "Ref": "LoadBalancerApp"
        }, {
          "Ref": "LoadBalancerApi"
        }],
    ..........
}

这不会为您提供您正在寻找的 UI，但它允许您在单个参数中指定多个负载均衡器名称。

使用CommaDelimitedList作为参数类型。

{
  "AWSTemplateFormatVersion": "2010-09-09",
  "Description": " App Demo / Jd / 01042016",
  "Parameters": {
    "LoadBalancers": {
      "Description": "Please refer the LoadBalancerNames which you want the instances to be registered to",
      "Type": "CommaDelimitedList",
      "Default": "web-app-demo-ext,web-api-demo-ext"
    }
  },
  "Resources": {
    "AppAutoScalingGroup": {
      "Type": "AWS::AutoScaling::AutoScalingGroup",
      "Properties": {
        "AvailabilityZones": {
          "Ref": "AZs"
        },
        "LoadBalancerNames": {
          "Ref": "LoadBalancers"
        }
      }
    }
  }
}
