如何從EC2實例導航到S3存儲桶文件夾？

Question

我想在我的EC2實例上安裝一些Python模塊。我有我需要在S3存儲桶上進行安裝的文件。我也可以通過Python boto從我的EC2實例連接到S3存儲桶，但是我無法訪問存儲桶內容以獲取我需要安裝的源文件。

Answer 1

使用s3cmd工具（http://s3tools.org/s3cmd）可以下載/上傳存儲在存儲桶中的文件。

Answer 2

以防萬一你想通過博託獲得在Python中的文件，這裏有一個簡單的例子：

import boto

    Very simple example showing how to download all keys in a bucket. 
    Assumes key names don't include path separators. Also assumes that 
    you don't have zillions of objects in the bucket. If you have a lot 
    you would want to get several download operations going in parallel. 
    """ 
    s3 = boto.connect_s3() 
    bucket = s3.lookup(bucket_name) 
    for key in bucket: 
     path = os.path.join(dst_dir, key.name) 
     key.get_contents_to_filename(path)
