AWS提供了一些工具来自动检测和标记未标记的资源,如Amazon Resource Group和Amazon Config。此外,还可以使用AWS Lambda和AWS Config Rule来编写自定义规则并执行自动化操作。
以下是使用AWS Lambda和AWS Config Rule进行自动化检测未标记资源的示例代码:
在AWS Lambda上创建一个Python函数,该函数使用boto3库使其能够在AWS中运行。以下代码将列出未标记的EC2实例:
import boto3 def lambda_handler(event, context): ec2 = boto3.client('ec2') response = ec2.describe_instances( Filters=[{'Name': 'tag:Name', 'Values': ['*']}] ) count = 0 for reservation in response['Reservations']: for instance in reservation['Instances']: if 'Tags' not in instance: count += 1 print("Number of untagged EC2 instances: ", count)
在AWS Config创建一个新的rule,该rule将触发Lambda函数并处理未标记的EC2实例。以下代码将创建一个名为'untagged-ec2-instances'的rule:
{ "configRuleName": "untagged-ec2-instances", "description": "Ensure all EC2 instances are tagged", "scope": { "complianceResourceTypes": [ "AWS::EC2::Instance" ] }, "source": { "owner": "AWS", "sourceIdentifier": "CONFIG_RULES" }, "inputParameters": { "tagKey": { "type": "String", "defaultValue": "Name" } }, "maximumExecutionFrequency": "TwentyFour_Hours", "resourceIdScope": "resourceTypesAndTags", "inputTransformer": { "inputPathsMap": { "resourceId": "$.configRuleInput.resourceId" }, "inputTemplate": "{"tagKey": "{{tagKey}}", "resourceId": "{{resourceId}}"}" }, "configureState": true, "executionRoleArn": "arn:aws:iam::123456789012:role/lambda-execution-role", "tags": [ { "key": "Name", "value": "untagged-ec2-instances" } ] }
现在可以测试自动化是否正常工作。创建一台未标记的EC2实例并查
