如何从 cloudformation 模板中的参数文件传递 public 键？

Question

我定义了以下 Cloudformation 模板，我想在其中传递参数文件中的 Public 键。 'MyPublicKey' 变量是字符串类型。我通过使用

来引用这个变量

EncodedKey !Ref MyPublicKey

在 PublicKeyConfig 下，如下所示。

AWSTemplateFormatVersion: "2010-09-09"

  Parameters:
    MyPublicKey:
      Type: String
      Description: 'Public key for some purpose'
      NoEcho: true

  Resources:
    CloudfrontPublicKey:
      Type: AWS::CloudFront::PublicKey
      Properties:
        PublicKeyConfig:
          CallerReference: 'some-caller-reference'
          Comment: 'Public key for signed url'
          Name: 'cloudfront-public-key'
          EncodedKey: !Ref MyPublicKey

    ...

parameter.json 文件看起来像这样。 public 键在原始 .pem 文件中是多行的，但我在字符串中的换行符处添加了新行字符 '\n'。

[
  {
    "ParameterKey": "MyPublicKey",
    "ParameterValue": "-----BEGIN PUBLIC KEY-----\naaaa\nbbbb\n-----END PUBLIC KEY-----"
  },
]

尝试更新堆栈时，出现以下错误：

Invalid request provided: AWS::CloudFront::PublicKey

似乎无法导入 public 密钥。

根据评论，传递值时需要额外的 \n 字符，Ref 应替换为 Sub 函数以放置字符串。

  Resources:
    CloudfrontPublicKey:
      Type: AWS::CloudFront::PublicKey
      Properties:
        PublicKeyConfig:
          CallerReference: 'some-caller-reference'
          Comment: 'Public key for signed url'
          Name: 'cloudfront-public-key'
          EncodedKey: !Sub "${MyPublicKey}"

下面是内联键示例：

生成密钥：

openssl genrsa -out private_key.pem 2048
openssl rsa -pubout -in private_key.pem -out public_key.pem

Cloudformationt 模板：

AWSTemplateFormatVersion: "2010-09-09"
Resources:
  CloudfrontPublicKey:
    Type: AWS::CloudFront::PublicKey
    Properties:
      PublicKeyConfig:
        CallerReference: 'some-caller-reference'
        Comment: 'Public key for signed url'
        Name: 'cloudfront-public-key'
        EncodedKey: |
          -----BEGIN PUBLIC KEY-----

          -----END PUBLIC KEY-----

列表键：

aws cloudfront list-public-keys|jq .PublicKeyList.Items[1]

输出：
