是否可以使用CFT将通知配置添加到现有S3存储桶？

I am still a newbie with AWS services.

我仍然是AWS服务的新手。

I would like to add a Lambda trigger on an existing S3 bucket using a CFT. Is that possible?

我想使用CFT在现有S3存储桶上添加Lambda触发器。那可能吗？

When I create a CFT in the following it is attempting to create a new S3 bucket and add an event notificaiton on it.

当我在下面创建CFT时，它尝试创建一个新的S3存储桶并在其上添加事件通知。

S3BUCKET_NOTIFCATION = Bucket(
    "S3Bucket",
    BucketName=s3_bucket("confidential", Ref(ENV)),
    NotificationConfiguration=NotificationConfiguration(
        LambdaConfigurations=[
            LambdaConfigurations(
                Event="s3:ObjectCreated:*",
                Filter=Filter(
                    S3Key=S3Key(
                        Rules=[Rules(Name="prefix", Value=Ref(inputKeyPrefix)),
                               Rules(Name="suffix", Value=".json")]
                    )
                ),
                Function=Ref(cost_function)
            )
        ]
    )
)

Is it possible to add the Notification configuration to an existing bucket?

是否可以将Notification配置添加到现有存储桶？

I've been unable to add NotificationConfiguration to an existing bucket as well. When you try, you'll get the error "CREATE_FAILED. Reason: S3_BUCKET already exists"

我也无法将NotificationConfiguration添加到现有存储桶中。当您尝试时，您将收到错误“CREATE_FAILED。原因：S3_BUCKET已存在”

This post is from 2013 detailing that modifications of a pre-existing bucket is not allowed. It appears to still be correct.

这篇文章来自2013年，详细说明不允许对现有存储桶进行修改。它似乎仍然是正确的。
