CloudWatch Log Groups deletion using AWS Lambda function

Hi,

I think this is exactly what you are looking for: https://repost.aws/questions/QUMcZ1aqV1Rwu-IozegdMF6g/delete-cloudwatch-log-groups-using-aws-lambda-function

Hope it helps ;)

I have edited the code created in this question to the code that meets your requirements.
https://repost.aws/questions/QUMcZ1aqV1Rwu-IozegdMF6g/delete-cloudwatch-log-groups-using-aws-lambda-function

The following code inserts an if statement in line 10 to determine if the retention period is less than 365 days and if the file is not encrypted by KMS.

import boto3

def lambda_handler(event, context):
    logs_client = boto3.client('logs')
    response = logs_client.describe_log_groups()

    for log_group in response['logGroups']:
        if 'retentionInDays' in log_group:
            retentionin_days = log_group['retentionInDays']
            if retentionin_days < 365 and 'kmsKeyId' not in log_group:
                log_group_name = log_group['logGroupName']
                logs_client.delete_log_group(logGroupName=log_group_name)

what if the log groups have never expire? how to delete that?
