amazon-web-services - 如何在 Cloudformation 模板/CDK 中添加 AWS IoT 预置模板

Question

我正在使用 Cloudformation 模板创建一个包含 IoT 队列配置模板的堆栈，根据 the document，IoT 配置模板主体应该是字符串类型。

我有这样的 IoT 队列配置模板:

{
  "Parameters": {
    "SerialNumber": {
      "Type": "String"
    },  
    "AWS::IoT::Certificate::Id": {
      "Type": "String"
    }
  },
  "Resources": {
    "certificate": {
      "Properties": {
        "CertificateId": {
          "Ref": "AWS::IoT::Certificate::Id"
        },
        "Status": "Active"
      },
      "Type": "AWS::IoT::Certificate"
    },
    "policy": {
      "Properties": {
        "PolicyName": "mypolicy"
      },
      "Type": "AWS::IoT::Policy"
    },
    "thing": {
      "OverrideSettings": {
        "AttributePayload": "MERGE",
        "ThingGroups": "REPLACE",
        "ThingTypeName": "REPLACE"
      },
      "Properties": {
        "AttributePayload": {       
          "SerialNumber": {
            "Ref": "SerialNumber"
          }          
        },             
        "ThingName": {
          "Ref": "SerialNumber"
        }
      },
      "Type": "AWS::IoT::Thing"
    }
  }
}

Cloudformation模板是这样的:

AWSTemplateFormatVersion: '2010-09-09'
Description: "Template to create iot"

Resources: 
  FleetProvisioningTemplate:
    Type: AWS::IoT::ProvisioningTemplate
    Properties: 
      Description: Fleet provisioning template
      Enabled: true      
      ProvisioningRoleArn: "arn:aws:iam::1234567890:role/IoT-role"      
      TemplateBody: String
      TemplateName: mytemplate

我尝试使用 IoT 配置模板的 JSON 字符串作为模板主体，但它不起作用。我的问题是如何使用 Cloudformation 模板创建 IoT 配置模板？

更新事实证明，我可以将 IoT 配置模板添加为“文字 block ”

AWSTemplateFormatVersion: '2010-09-09'
Description: "Template to create iot"

Resources: 
  FleetProvisioningTemplate:
    Type: AWS::IoT::ProvisioningTemplate
    Properties: 
      Description: Fleet provisioning template
      Enabled: true      
      ProvisioningRoleArn: "arn:aws:iam::1234567890:role/IoT-role"      
      TemplateBody: |
        {
          "Parameters": {
            "SerialNumber": {
              "Type": "String"
            },
            "AWS::IoT::Certificate::Id": {
              "Type": "String"
            }
          },
          "Resources": {            
            "certificate": {
              "Properties": {
                "CertificateId": {
                  "Ref": "AWS::IoT::Certificate::Id"
                },
                "Status": "Active"
              },
              "Type": "AWS::IoT::Certificate"
            },
            "policy": {
              "Properties": {
                "PolicyName": "cto-full-function-dev"
              },
              "Type": "AWS::IoT::Policy"
            },
            "thing": {
              "OverrideSettings": {
                "AttributePayload": "MERGE",
                "ThingGroups": "DO_NOTHING",
                "ThingTypeName": "REPLACE"
              },
              "Properties": {
                "AttributePayload": {},
                "ThingGroups": [],
                "ThingName": {
                  "Ref": "SerialNumber"                  
                },
                "ThingTypeName": "cto"
              },
              "Type": "AWS::IoT::Thing"
            }
          }
        }

      TemplateName: mytemplate

但是，一旦我按照 the cloudformation document 的说明添加了 PreProvisioningHook，模板就会失败并出现无效请求错误。

                },
                "Status": "Active"
              },

              "Properties": {
                "AttributePayload": {},
                "ThingGroups": [],

                  "Ref": "SerialNumber"                  
                },
                "ThingTypeName": "cto"
              },
              "Type": "AWS::IoT::Thing"
            }
          }
        }

      TemplateName: mytemplate

我也在 here 上提出了问题，但没有运气。有人遇到同样的问题并解决了吗？

我终于弄清楚了，但想分享一下，以防有人有同样的问题。

AWS IoT 文档没有提及这一点，但如果您想为预配置模板添加 PreProvisioningHook，则需要向 IoT 授予对 lambda(又名 PreProvisioningHook)的访问权限，因此在 Cloudformation 模板中添加如下内容:

LambdaAddPermission:
    Type: AWS::Lambda::Permission
    Properties:
      Action: lambda:InvokeFunction
      FunctionName: !GetAtt PreProvisionHook.Arn 
      Principal: iot.amazonaws.com 

在配置模板资源中，确保您有:

PreProvisioningHook:               
        PayloadVersion: '2020-04-01'
        TargetArn: {
          "Fn::GetAtt": [
            "PreProvisionHook",
            "Arn"
          ]
        }
