AWS Autoscale 负载均衡与 Cloudformation

AWS Autoscale Load Balancing with Cloudformation

我正在尝试创建一个 EC2 实例,它将使用自动缩放,附加到负载均衡器。

很遗憾,我遇到了错误

The availability zones of the specified subnets and the AutoScalingGroup do not match

但是,这是我当前的 Cloudformation 脚本:

"ApiAutoScaling" : {
  "Type" : "AWS::AutoScaling::AutoScalingGroup",
  "Properties" : {
    "VPCZoneIdentifier" : [ "subnet-5ff05206", "subnet-b1109fc6", "subnet-948ce5f1" ],
    "InstanceId" : {
      "Ref" : "ApiEC2"
    },
    "MaxSize" : 3,
    "MinSize" : 1,
    "LoadBalancerNames" : [ "Api" ]
  }
},
"ApiLoadBalancer" : {
  "Type" : "AWS::ElasticLoadBalancing::LoadBalancer",
  "Properties" : {
    "LoadBalancerName" : "Api",
    "Listeners" : [
      {
        "InstancePort" : "80",
        "InstanceProtocol" : "HTTP",
        "LoadBalancerPort" : "80",
        "Protocol" : "HTTP"
      },
      {
        "InstancePort" : "80",
        "InstanceProtocol" : "HTTP",
        "LoadBalancerPort" : "443",
        "Protocol" : "HTTPS",
        "SSLCertificateId" : "arn:aws:iam::xxx"
      }
    ],
    "SecurityGroups" : [ "sg-a88444cc" ],
    "Subnets" : [ "subnet-5ff05206", "subnet-b1109fc6", "subnet-948ce5f1" ]
  }
}

如您所见,我的自动缩放组和负载均衡器的子网列表相同。显然我误解了它应该如何工作,但我无法解决。

尝试为自动缩放组指定 AvailabilityZones 属性。默认情况下它使用所有区域,因此如果您的子网仅使用区域的子网,您将收到此错误消息。

(正如评论中指出的那样,"AvailabilityZones" : { "Fn::GetAZs" : "" } 应该可以解决问题。)
