Docker Python File Input Selector

Question

I'm trying to configure a Docker image so that a user can type in "docker run image" and have a window pop up to select the input file. I tried to use Tkinter when creating the Docker image, but the Python script errors out when it tries to load Tkinter.

Since Tkinter did not work I tried to just switch to a normal input query using:

path= input('Input the file path:\n')

But now I am getting an "EOFError: EOF when reading a line" when it gets to the input() line.

My Dockerfile is as follows

FROM python:3
ADD script.py /
RUN pip install xlrd
RUN pip install numpy
RUN pip install matplotlib
CMD [ "python", "./script.py" ]

Any ideas as to why this is happening? I'm very new to using Docker so any help would be much appreciated :)

You need to run the container with docker run -ti image to make sure that it runs in interactive mode with the terminal attached.

Running X11 GUI applications is a bit more tricky since you need to give the container access to your display. This blog post describes the process in more details.
