使用 AWS LAMBDA 删除旧的手动集群快照 RDS

Question

在我的 AWS Lambda 的 python 代码下方，我想通过使用它来删除 OLD MANUAL RDS SNAPSHOTS，但它仍然无法正常工作并出现错误，我需要帮助来调试和更正此 lambda 脚本。非常感谢。

import boto3
from os import getenv
import datetime
from datetime import date
client = boto3.client('rds')
ClientName = getenv('CLIENT_NAME')
today = date.today()

def lambda_handler(event, context):
    delete_db_cluster_snapshot():
    snapshots_marker = ""
    while snapshots_marker != None:
        snapshots = client.describe_db_cluster_snapshots(Marker=snapshots_marker)
        
        if 'Marker' in snapshots:
            snapshots_marker = snapshots['Marker']
        else:
            snapshots_marker = None
            
        for snapshot in snapshots['DBClusterSnapshots']:
            if snapshot["SnapshotType"] == "manual" and ClientName in snapshot["DBClusterIdentifier"] and snapshot ["SnapshotCreateTime"].date() < today:
                client.delete_db_cluster_snapshot(DBClusterSnapshotIdentifier=snapshot["DBClusterSnapshotIdentifier"])
                
delete_db_cluster_snapshot()

您的代码看起来不错，但您应该删除 delete_db_cluster_snapshot() sub-function:

import boto3
from os import getenv
import datetime
from datetime import date

client = boto3.client('rds')
ClientName = getenv('CLIENT_NAME')
today = date.today()

def lambda_handler(event, context):
    snapshots_marker = ""
    while snapshots_marker != None:
        snapshots = client.describe_db_cluster_snapshots(Marker=snapshots_marker)
        
        if 'Marker' in snapshots:
            snapshots_marker = snapshots['Marker']
        else:
            snapshots_marker = None
            
        for snapshot in snapshots['DBClusterSnapshots']:
            if snapshot["SnapshotType"] == "manual" and ClientName in snapshot["DBClusterIdentifier"] and snapshot ["SnapshotCreateTime"].date() < today:
                client.delete_db_cluster_snapshot(DBClusterSnapshotIdentifier=snapshot["DBClusterSnapshotIdentifier"])
