我正在运行以下图像：
docker run -it --rm python:3.4-slim /bin/bash
在它里面(作为root),我安装了：
root@dab02ca9c61d:~# apt-get update && apt-get install nano
然后是boto
root@dab02ca9c61d:~# pip install boto
然后我在/root/.boto中写了以下内容：
[Credentials]
aws_access_key_id = some_long_string
aws_secret_access_key = another_bigger_string
[Boto]
debug = 2
num_retries = 10
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
Python 3.4.4 (default,Jan 8 2016,00:24:55)

我已经阅读了Boto Credential Error with Python on Windows Boto: Dynamically get aws_access_key_id and aws_secret_access_key in Python code from config?和另一个问题.什么都行不通.
之后,我查看了boto.pyami的源代码,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.
boto.config使用ConfigParser,如果我使用它,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：我安装了awscli并且没有问题,将配置文件放在/etc/boto.cfg中并且不起作用.
我已经在这周末度过了所有的想法吗？
最佳答案
由于我不能发表评论,我会把它作为答案,但不完全确定Docker的问题是什么,但我也能够复制问题.可能想在boto上发一个问题,看看有人可以提供帮助.但是,我能够通过设置环境变量AWS_ACCESS_KEY_ID,AWS_SECRET_ACCESS_KEY然后启动python来使其工作.不知道这是否有所帮助,但只是想把它扔出去,因为我花了一些时间来看它.
