Question

我试图让docker-py正常工作，并且遇到了一个可能与docker-py无关的基本问题。

我通过pip安装了docker-py（这里是重新运行它的输出 - 应该回答版本问题）：

>pip install docker-py

Requirement already satisfied: websocket-client>=0.32.0 in /usr/local/lib/python2.7/site-packages (from docker-py)

尝试执行一些代码示例（来自http://containertutorials.com/py/docker-py.html）并且正在失败之门：

>python

>>> from docker import client
>>> cli = Client(base_url='unix://var/run/docker.sock')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'Client' is not defined

尝试使用AutoVersionClient（client = AutoVersionClient(base_url='unix://var/run/docker.sock')）的不同代码示例时，我遇到了类似的失败，但是由于未定义类似的AutoVersionClient而失败。

这确实感觉就像我系统上的核心配置问题，但我不知道问题出在哪里。

客户和客户不一样吗？

>>> from docker import client

Answer 2

如果您已安装docker-py 2.0或更新版本，则客户端已重命名。现在，低级API是docker.APIClient，而不是docker.Client。

docker-py error：NameError：name＆＃39; Client＆＃39;没有定义
