python - 为什么我的 python 脚本(导入 docker-py 包(下面链接))给出错误而不是运行我的 docker 容器？

Question

我正在尝试使用 https://docker-py.readthedocs.io/en/stable/index.html制作一个运行我的容器的 python 脚本。

安装包后(使用 import docker 导入，我的镜像名为“janus”)，这是我的 python 脚本:

import docker
client = docker.from_env()
client.containers.run("janus")

当我运行脚本时，我得到

Traceback (most recent call last):
  File "/home/milanlakhani/.local/lib/python3.6/site-packages/requests/packages/urllib3/util/timeout.py", line 124, in _validate_timeout
    float(value)
TypeError: float() argument must be a string or a number, not 'Timeout'

During handling of the above exception, another exception occurred:

也许我错过了一些非常明显的东西，因为我是初学者，但在 docker-py 文档中我不明白为什么这不起作用。 (我认为我不需要设置环境变量，例如 DOCKER_HOST、DOCKER_TLS_VERIFY、DOCKER_CERT_PATH 因为我在我的机器上运行 docker据我所知，这是正常的方式。)

如果您需要更多详细信息，请告诉我，我还可以发送用于构建镜像的 Dockerfile，该文件公开端口并具有命令

CMD /usr/bin/janus -o --configs-folder=/usr/local/share/ct-camera/janus

但是，我尝试了其他图像和包含存储库的图像名称，并且无论图像如何，错误始终相同!

我还尝试了此包中的其他命令，但发生了同样的事情。

我认为您需要提供正确的图像名称 - 类似于:

client.containers.run("myrepo.com/janus")

并确保拥有最新的requests包:

pip3 install -U requests
