添加 Amazon 托管 Config 规则

以下命令提供用于添加 Amazon 托管 Config 规则的 JSON 代码：

aws configservice put-config-rule --config-rule file://RequiredTagsForEC2Instances.json

RequiredTagsForEC2Instances.json 是一个包含规则配置的 JSON 文件：

{
  "ConfigRuleName": "RequiredTagsForEC2Instances",
  "Description": "Checks whether the CostCenter and Owner tags are applied to EC2 instances.",
  "Scope": {
    "ComplianceResourceTypes": [
      "AWS::EC2::Instance"
    ]
  },
  "Source": {
    "Owner": "AWS",
    "SourceIdentifier": "REQUIRED_TAGS"
  },
  "InputParameters": "{\"tag1Key\":\"CostCenter\",\"tag2Key\":\"Owner\"}"
}

对于该ComplianceResourceTypes属性，此 JSON 代码将范围限制为该AWS::EC2::Instance类型的资源，因此 Amazon Config 将仅根据规则评估 EC2 实例。由于该规则是托管规则，因此 Owner 属性设置为 AWS，SourceIdentifier 属性设置为规则标识符 REQUIRED_TAGS。对于 InputParameters 属性，指定了规则所需的标签键 CostCenter 和 Owner。

如果命令成功， Amazon Config 将不返回任何输出。要验证规则配置，请运行 describe-config-rules 命令并指定规则名称。

添加客户托管的 Config 规则

以下命令将提供用于添加客户托管 Config 规则的 JSON 代码：

aws configservice put-config-rule --config-rule file://InstanceTypesAreT2micro.json

InstanceTypesAreT2micro.json 是一个包含规则配置的 JSON 文件：

{
  "ConfigRuleName": "InstanceTypesAreT2micro",
  "Description": "Evaluates whether EC2 instances are the t2.micro type.",
  "Scope": {
    "ComplianceResourceTypes": [
      "AWS::EC2::Instance"
    ]
  },
  "Source": {
    "Owner": "CUSTOM_LAMBDA",
    "SourceIdentifier": "arn:aws:lambda:us-east-1:123456789012:function:InstanceTypeCheck",
    "SourceDetails": [
      {
        "EventSource": "aws.config",
        "MessageType": "ConfigurationItemChangeNotification"
      }
    ]
  },
  "InputParameters": "{\"desiredInstanceType\":\"t2.micro\"}"
}

对于该ComplianceResourceTypes属性，此 JSON 代码将范围限制为该AWS::EC2::Instance类型的资源，因此 Amazon Config 将仅根据规则评估 EC2 实例。由于此规则是客户托管规则，因此该Owner属性设置为CUSTOM_LAMBDA，并且该SourceIdentifier属性设置为 Lambda 函数 Amazon 的 ARN。SourceDetails 对象为必填项。当 Confi Amazon g 调用 Amazon Lambda 函数来根据规则评估资源时，为该InputParameters属性指定的参数将传递给 Lambda 函数。

如果命令成功， Amazon Config 将不返回任何输出。要验证规则配置，请运行 describe-config-rules 命令并指定规则名称。

        try:

aws configservice delete-config-rule --config-rule-name MyConfigRule

class ConfigWrapper:

    def __init__(self, config_client):
