amazon-web-services - 将内联策略添加到 aws SAM 模板

Question

我正在使用 SAM 模板来创建我的无服务器应用程序。

使用标签 Policies在资源的属性下，我可以添加这样的标准策略:

Resources:
  QueryFunction:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: query/
      Handler: app.lambda_handler
      Policies:
        - AmazonDynamoDBFullAccess
        - AWSLambdaVPCAccessExecutionRole
      Runtime: python3.7

问题是我需要附加内联策略以仅访问特定的 DynamoDB 表。

如何将此内联策略放入模板中？

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "dynamodb:*",
            "Resource": "dynamo_db_table_endpoint"
        }
    ]
}

谢谢

尝试这个:

QueryFunction:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: query/
      Handler: app.lambda_handler
      Policies:
        - AmazonDynamoDBFullAccess
        - AWSLambdaVPCAccessExecutionRole
        - Version: '2012-10-17' # Policy Document
          Statement:
            - Effect: Allow
              Action:
                - dynamodb:*
              Resource: 'arn:aws:dynamodb:*:*:table/dynamo_db_table_endpoint'
      Runtime: python3.7

Amazon DynamoDB: Allows Access to a Specific Table

如果您想通过您的 表名作为参数更改 Resource: 'arn:aws:dynamodb:*:*:table/dynamo_db_table_endpoint'到 Resource: !Sub 'arn:aws:dynamodb:${AWS::Region}:${AWS::AccountId}:table/${tableName}'
希望这可以帮助
