Lambda function 使用 Boto 刪除 S3 存儲桶

Question

I am working on a Boto script to delete the resource when invoked by a lambda function, I am not sure how to invoke the delete function using Lambda, "path" has the resource to be deleted and below is the lambda function being used to delete資源。 提前致謝。

print(path)
def delete_bucket(path):  
    while True:
        objects = s3.list_objects(Bucket=path)
        content = objects.get('Contents', [])
        if len(content) == 0:
            break
        for obj in content:
            s3.delete_object(Bucket=path, Key=obj['Key'])
    s3.delete_bucket(Bucket=path)
    
def lambda_handler(event, context):

    delete_bucket(path)

以下代碼在 Python 3.8 上驗證；

import boto3


def get_s3_client():
    return boto3.client('s3', region_name='eu-west-1') #change region_name as per your setup

def delete_bucket(bucket_name): #here bucket_name can be path as per logic in your code 
    s3_client = get_s3_client()
    while True:
        objects = s3_client.list_objects(Bucket=bucket_name)
        content = objects.get('Contents', [])
        if len(content) == 0:
            break
        for obj in content:
            s3_client.delete_object(Bucket=bucket_name, Key=obj['Key'])
    s3_client.delete_bucket(Bucket=bucket_name)
    
def lambda_handler(event, context):
    # put your existing logic here
    delete_bucket(path)  

注意：如果您為存儲桶啟用了版本控制，那么您將需要額外的邏輯來使用list_object_versions列出對象，然后遍歷此類版本 object 以使用delete_object刪除它們
