泊坞内的博托奇怪的行为
我正在运行以下image ：
docker run -it --rm python:3.4-slim /bin/bash
里面（作为root ），我安装了：
root@dab02ca9c61d:~# apt-get update && apt-get install nano
然后boto
root@dab02ca9c61d:~# pip install boto
然后我在/root/.boto写下了以下/root/.boto ：
[Credentials] aws_access_key_id = some_long_string aws_secret_access_key = another_bigger_string [Boto] debug = 2 num_retries = 10
（这个文件和我在主机上的文件是一样的）
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:~#
（完全一样，我在我的主机/本地机器）
如果我解雇了python控制台：
root@dab02ca9c61d:~# python Python 3.4.4 (default, Jan 8 2016, 00:24:55) [GCC 4.9.2] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import boto >>> boto.connect_s3() Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python3.4/site-packages/boto/__init__.py", line 141, in connect_s3 return S3Connection(aws_access_key_id, aws_secret_access_key, **kwargs) File "/usr/local/lib/python3.4/site-packages/boto/s3/connection.py", line 190, in __init__ validate_certs=validate_certs, profile_name=profile_name) File "/usr/local/lib/python3.4/site-packages/boto/connection.py", line 569, in __init__ host, config, self.provider, self._required_auth_capability()) File "/usr/local/lib/python3.4/site-packages/boto/auth.py", line 987, in get_auth_handler 'Check your credentials' % (len(names), str(names))) boto.exception.NoAuthHandlerFound: No handler was ready to authenticate. 1 handlers were checked.

如果我激活日志logging：

（这个例子在我的本地机器上运行）
我已经在Windows Boto 上用Python读过Boto Credential Error ：在configuration文件中dynamic获取Python代码中的aws_access_key_id和aws_secret_access_key？ 和另一个问题。 没有任何工作
之后，我回顾了boto.pyami的源代码，如果我一行一行地执行一无所获。
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，它的工作原理是：
>>> import configparser >>> config = configparser.ConfigParser() >>> config.read('~/.boto') [] >>> config.read('/root.boto') ['/root/.boto'] >>> config.get('Credentials', 'aws_access_key_id') 'some_long_string' >>>
（请注意，如果我使用相对path它没有工作）
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testing：我instaed awscli和它的工作没有任何问题，把configuration文件在/etc/boto.cfg并没有工作。
我已经在这个周末度过了所有的想法？
由于我不能评论，我会把这个作为答案，但不完全确定docker的问题是什么，但我也能够复制这个问题。 可能想在boto上做一个问题，看看有没有人可以帮忙。 不过，我可以通过设置环境variablesAWS_ACCESS_KEY_ID ， AWS_SECRET_ACCESS_KEY然后启动python来实现它。 不知道这是否有帮助，但只是想把它扔在那里，因为我花了一些时间看看它。
