boto在docker中的奇怪行为

我正在运行以下内容image:

docker run -it --rm python:3.4-slim  /bin/bash

在里面(as root),我安装:

root@dab02ca9c61d:~# apt-get update && apt-get install nano

然后 boto

root@dab02ca9c61d:~# pip install boto

然后我写了以下内容/root/.boto:

[Credentials]
aws_access_key_id = some_long_string
aws_secret_access_key = another_bigger_string

[Boto]
debug = 2
num_retries = 10

(此文件与我在主机中的文件相同)

版本是:

root@dab02ca9c61d:~# python -V
Python 3.4.4
root@dab02ca9c61d:~# pip list
boto (2.38.0)
pip (7.1.2)
setuptools (18.2)
root@dab02ca9c61d:~# 

(与我在主机/本地机器上完全相同)

如果我解雇了python控制台:

root@dab02ca9c61d:~# python

(此示例在我的本地计算机中运行)

我已经在Windows Boto 上阅读了Python上的Boto Credential Error :动态地从配置中获取Python代码中的aws_access_key_id和aws_secret_access_key？还有一个问题.什么都行不通.

在那之后,我查看源代码boto.pyami和如果我逐行执行什么都没有.

例如:

>>> boto.config.sections()
['Credentials', 'Boto']
>>> boto.config.get_value('Credentials', 'aws_access_key_id')
>>> 

请注意,最后一个命令返回None.

在boto.config使用ConfigParser中,如果我使用,它的工作原理:

>>> import configparser
>>> config = configparser.ConfigParser()
>>> config.read('~/.boto')
[]
>>> config.read('/root.boto')                                         
['/root/.boto']
>>> config.get('Credentials', 'aws_access_key_id')
'some_long_string'
>>> 

(注意,如果我使用相对路径它不起作用)

最后,如果我使用:

>> boto.connect_s3('some_long_string', 'another_bigger_string')
2016-01-11 02:05:33,636 boto [DEBUG]:Using access key provided by client.
2016-01-11 02:05:33,636 boto [DEBUG]:Using secret key provided by client.
S3Connection:s3.amazonaws.com
>>> 

我做了另一个测试:我操作awscli并且它没有问题,将配置文件放入/etc/boto.cfg并且不起作用.

我已经在这周末度过了所有的想法吗？
