使用 AWS Lambda 在 7 天后删除快照

Question

我尝试使用以下脚本为具有标签名称[备份或备份]的实例创建快照> 根据https://serverlesscode.com/post/lambda-schedule-ebs-snapshot-backups/ && https://serverlesscode.com/post/lambda-schedule-ebs-snapshot-backups-2/ 如第一个和第二个链接中所述，我已经成功创建了带有 DeleteOn 标签的快照。第二个链接的后半部分解释了如何在指定日期删除这些快照。根据该代码，我有以下内容可以在 7 天后删除快照。

这是代码：

import boto3
import re
import datetime

ec = boto3.client('ec2')
iam = boto3.client('iam')

def lambda_handler(event, context):
    account_ids = list('123456789011')
    try:       
        iam.get_user()
    except Exception as e:
        account_ids.append(re.search(r'(arn:aws:sts::)([0-9]+)', str(e)).groups()[1])


    delete_on = datetime.date.today().strftime('%Y-%m-%d')
        filters = [
        {'Name': 'tag-key', 'Values': ['DeleteOn']},
        {'Name': 'tag-value', 'Values': [delete_on]},
    ]
    snapshot_response = ec.describe_snapshots(OwnerIds=account_ids, Filters=filters)


    for snap in snapshot_response['Snapshots']:
        print "Deleting snapshot %s" % snap['SnapshotId']
        ec.delete_snapshot(SnapshotId=snap['SnapshotId'])

通过这样做，我收到以下错误：

'NoneType' object has no attribute 'groups': AttributeError
Traceback (most recent call last):
  File "/var/task/lambda_function.py", line 27, in lambda_handler
    account_ids.append(re.search(r'(arn:aws:sts::)([0-9]+)', str(e)).groups()[1])
  AttributeError: 'NoneType' object has no attribute 'groups'

我通过这种方式更新我上面的部分代码解决了这个问题：

def lambda_handler(event, context):
account_ids = ['123456789011']
