问题描述
我定义了以下 Cloudformation 模板，我想在其中从参数文件传递公钥。 'MyPublicKey' 变量是字符串类型。我使用
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。原始 .pem 文件中的公钥是多行的，但我在字符串中任何有换行符的地方添加了新行字符 '\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
好像不能导入公钥。
解决方法
根据注释，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}"
以下是内联键示例：
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:

Properties:
PublicKeyConfig:

Comment: 'Public key for signed url'
Name: 'cloudfront-public-key'
