WORKDIR /app

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

# Install any needed packages specified in requirements.txt

Answer 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 .
