Question

我在窗口上使用docker。以下是我的docker文件：

FROM microsoft/windowsservercore:latest
FROM python:3.7
RUN pip install flask
CMD ["cmd"]

当我尝试构建docker映像时，它会抛出以下异常：

>docker build  D:\HCL\Docker\

Sending build context to Docker daemon  14.34kB

我已经检查了docker可以访问互联网，但是无法通过https下载任何软件包。
我已检查通过http下载文件，并且工作正常。
我能够在同一docker文件中安装windowcore和python。
我只是遇到点子问题。
我已登录到容器并手动运行pip命令，但遇到相同的错误。

Pip安装在窗口上的Docker容器中不起作用
