在 Cloudformation 的 SSM Parameter Store 中创建 JSON 值

Question

I need to create SSM parameter store in Cloudformation to store JSON

Here is my Template

Resources:
  WebServersSSM:
    Type: AWS::SSM::Parameter
    Properties: 
      AllowedPattern: String
      DataType: text
      Description: WebServers CloudWatch Agent Configuration
      Name: WebServersSSM
      Type: String
      Tier: Standard
      Value: |
        {
           ... My JSON File  
        }

I am facing error

Parameter value, cannot be validated against allowedPattern: String (Service: AmazonSSM; Status Code: 400; Error Code: ParameterPatternMismatchException; Request ID: a7c2f063-9e63-4b4c-981b-c9ad05e56166; Proxy: null)

Answer 1

The AllowedPattern is a regular expression to validate the pattern and not the expected type. Remove it and it should work.
