Sagemath in Docker cannot access host files

asked 2025-08-03 19:40:21 +0200

I spent the last day trying to compile sagemath from sources on Fedora 42 KDE. I don't want to list all the problems I had. At the end it "almost" worked, but plot do not seem to work.

Then I tried with Docker, that is much more simple, the only drawback is that from the container I cannot access host files. I know I can tell the "docker run" command to mount a host directory, but the only place I found more or less convenient is /mnt, but then I have permissions problems. Also, I can build a new image on top of the given one, in which make some modification, for example the creation of a directory under the home, but I don't know well Docker, so I would like to ear the suggestions of people more expert than me.

Given that I use Fedora, that in turn use SELinux, there was a change of security context to do on the host file under the host dir, before running for the first time the container with the mount

chcon -Rt svirt_sandbox_file_t ~/host/dir

Then, the following script, run as root, do the job

#!/bin/bash

docker run \
    -p8888:8888 \
    --name sagemath \
    -v ~/host/dir:/home/sage/sage/build \
    sagemath/sagemath:latest sage-jupyter
docker stop sagemath
docker rm sagemath

Only the first time it is run, it download the sagemath Docker image file.
