Dockerfile fails when installing a python local package with permission denied

Question

I have this Dockerfile:

FROM jupyter/scipy-notebook

ADD /dist /our_controller/dist
ADD /wheelhouse /our_controller/wheelhouse
COPY setup.py /our_controller
COPY package.py /our_controller
COPY README.md /our_controller
WORKDIR /app
# add our_controller to python 3.7
RUN python3 -m pip install -e ../our_controller/ --user

I use this command docker build -f ./Dockerfile . from the base directory of my project. I had previously used python3 setup.py package to create the ./dist directory content and all dependencies are present in the ./wheelhouse directory as *.whl files, generated by the package.py.

I get this error:

docker build -f ./Dockerfile .

All files in the project directory are owned by the user, none by root. I have created several Dockerfile in the past but installing a local package I have not attempted previously. I have clearly missed something. Can someone point it out?

Answer 1

I hit this issue as well. I wound up building a wheel and then adding and installing the wheel in the image.

local

python setup.py bdist_wheel

Dockerfile

FROM jupyter/scipy-notebook
RUN conda install ipdb lxml -y
ADD dist/my_package-0.0.1-py3-none-any.whl my_package-0.0.1-py3-none-any.whl
RUN pip install my_package-0.0.1-py3-none-any.whl
