Can't install pip packages inside a docker container with windows

问题

Dockerfile

# Use an official Python runtime as a base image
FROM python:3.8.1-windowsservercore

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
ADD . /app

# Install any needed packages specified in requirements.txt
RUN pip install --trusted-host pypi.python.org -r requirements.txt

# Make port 80 available to the world outside this container
EXPOSE 80

# Define environment variable
ENV NAME World

# Run app.py when the container launches
CMD ["python", "app.py"]

It is giving me this error

回答1:

• If you have n/w proxy in between use below command :
  docker build --no-cache --build-arg HTTP_PROXY=http://xx.xx.xx.xx:xx --build-arg HTTPS_PROXY=http://xx.xx.xx.xx:xx --network=host -t helloworkapp .
• If you don't have any proxy use this command (use host n/w for downloading packages):
  docker build --no-cache --network=host -t helloworkapp .
