This is my Dockerfile
FROM python:3.10 #create a working directory WORKDIR /app #gets our requirements.txt file into our image COPY requirements.txt requirements.txt # Install packages specified in requirements.txt RUN pip install -r requirements.txt #adds our source code into the image COPY . . CMD [ "python", "manage.py" , "runserver" ,"0.0.0.8000"]when i am running above code in windows powershell with the command
docker build -t "test" .,I am getting the error as in attachment. The error occurs while executing pip install requirement.txt file

Looks like a network problem. Are you able to run
pip successfully on the host?

I even tried to install setuptools by specifying in requirements.txt.But still the errror persists.
RE: Docker -building a python image - ndc85430 - Jul-13-2022
It doesn't look like a problem with setuptools itself - the connection is timing out. Do you have more network issues? Is there a firewall or something that isn't letting you access PyPI over HTTPS?

Yes,there is a firewall and i modified the statements as below in dockerfile .I am able to install all dependencies,but image not created because of above error
RUN pip --proxy http://10.1XX.XXX.XX:80XX install --upgrade pip RUN pip --proxy http://10.1XX.XXX.XX:80XX install --upgrade setuptools>=40.8.0 RUN pip --proxy http://10.1XX.XXX.XX:80XX install -r requirements.txtI tried 2 ways,
1)I added a setuptools even in requirements.txt
2)added pip --proxy http://10.1XX.XXX.XX:80XX install --upgrade setuptools>=40.8.0 in docker file
Both ways still give the same error as i posted before.But I could install all dependencies mentioned in requirements.txt.After installing all libraries,the before mentioned error pops up
