由LaunchConfig创建的实例的CloudFormation标记

Question

How can I add a Name tag to instances created by CloudFormation's LaunchConfig? I thought it would be in this section, but it is not an option.

{
   "Type" : "AWS::AutoScaling::LaunchConfiguration",
   "Properties" : {
      "AssociatePublicIpAddress" : Boolean,
      "BlockDeviceMappings" : [ BlockDeviceMapping, ... ],
      "ClassicLinkVPCId" : String,
      "ClassicLinkVPCSecurityGroups" : [ String, ... ],
      "EbsOptimized" : Boolean,
      "IamInstanceProfile" : String,
      "ImageId" : String,
      "InstanceId" : String,
      "InstanceMonitoring" : Boolean,
      "InstanceType" : String,
      "KernelId" : String,
      "KeyName" : String,
      "PlacementTenancy" : String,
      "RamDiskId" : String,
      "SecurityGroups" : [ SecurityGroup, ... ],
      "SpotPrice" : String,
      "UserData" : String
   }
}

I wondered if I should create an instance resource and put settings in there, and then link it to the launchconfig, but I can't find any documentation to support that idea.

AWS::AutoScaling::LaunchConfiguration is meant to be used in conjunction with AWS::AutoScaling::AutoScalingGroup . The AutoScalingGroup itself has a Tags property that can be used for setting the instance name among other tags. One note about these tags, they're slightly different than the tags used in most other CloudFormation resources, as they have a PropagateAtLaunch property, which says if the tag should be applied to instances of the AutoScalingGroup, or just the AutoScalingGroup itself. See the Auto Scaling Tags Property Type for more details.
