python - 如何从 EC2 实例导航到 S3 存储桶文件夹？

Question

我想在我的 EC2 实例上安装一些 Python 模块。我有在 S3 存储桶上安装所需的文件。我还可以通过 Python boto 从我的 EC2 实例连接到 S3 存储桶，但我无法访问存储桶内容以获取我需要安装的源文件。

以防万一你想通过 boto 在 Python 中获取文件，这里有一个简单的例子:

import boto
import os

def download_keys(bucket_name, dst_dir):

    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)
