不允许为VPC创建EC2实例 [英] Create an EC2 instance for a VPC not allowed

问题描述

是否可以将EC2实例模板的VPCId定义为属性？

Is it possible to define VPCId for an EC2 instance template as a property?

我尝试执行的操作类似于

I am trying to do is something like,

"Resources" : {
"Ec2Instance" : {
  "Type" : "AWS::EC2::Instance",
  "Properties" : { 
    "SecurityGroups": [ { "Ref": "AWSSecurityGroups" } ],     
    "KeyName" : { "Ref" : "KeyName" },
    "InstanceType" : { "Ref" : "InstanceType" },
    "Tags" : [ { "Key" : "Name", "Value" : "Softnas-CF" }],
    "ImageId" : { "Fn::FindInMap" : [ "RegionMap", { "Ref" : "AWS::Region" }, "AMI" ]},
    "VpcId" :  { "Ref" : "VPCId" },     
   .....some other stuff...
},

在我的参数中，我定义了VPCId，

In my parameters I define VPCId,

"Parameters" : {
....
"VPCId": {
   "Description": "Name of an existing VPC ID",
   "Type": "AWS::EC2::VPC::Id",
   "ConstraintDescription": "must be the name of an existing VPC Id."
},  
...

}，

但是当我创建堆栈（通过.net api）时，它回滚并出现错误

But when I creating the stack (via the .net api), it Rollback with the error

遇到不受支持的属性VpcId

Encountered unsupported property VpcId

这是不允许的，我找不到任何文档来做到这一点。做这个实验。如果使用模板创建EC2实例，是否总是在默认VPC中创建它？

Isn't this allowed, I couldn't find any documentation to do this. Doing this as an experiment. Is the EC2 instance always gets created in the default VPC if created using templates?

推荐答案

VpcId 在 Ec2Instance中不受支持：属性

使用 SubnetId 。

"Ec2Instance" : {
  "Type" : "AWS::EC2::Instance",
  "Properties" : {
    "SecurityGroupIds" : [ { "Ref" : "xxxxx" } ],
    "Tags" : [ { "Key" : "Name", "Value" : "xxx" } ],
    "ImageId" : { "Fn::FindInMap" : [ "RegionMap", { "Ref" : "AWS::Region" }, "AMI" ]},
    "SubnetId" : { "Ref" : "VpcSubnet" },
    "InstanceType"   : { "Ref" : "InstanceType" },
    ....

"VpcSubnet": {
  "Description" : "Enter the VPC subnet",
  "Type" : "AWS::EC2::Subnet::Id",
  "Default" : ""
},
