Being both nonprivileged and root inside Docker container
I want to use pandoc inside docker. The image looks like this:
FROM debian:buster-slim
RUN apt-get update && apt-get install -y pandoc texlive
WORKDIR /home
This is build.sh
inside the project:
cp *.ttf /usr/local/share/fonts/ && fc-cache;
pandoc -o output.pdf input.md
that I want to run like this:
docker run --rm -t -v $(pwd):/home pandoc_container build.sh
This results in output.pdf
being owned by root on my host. When doing:
docker run --user $(id -u) --rm -t -v $(pwd):/home pandoc_container build.sh
instead, the file will be owned by me, but the font files can not be copied to that dir, due to missing write permissions. Adding
RUN chmod a+w /usr/local/share/fonts/
to the Dockerfile solves this, but then the command fc-cache
fails with a lot of failed to write cache
errors also due to missing write permissions in lots of directories.
Copying the font files to ~/.fonts
will not work either, because the user created by --user $(id -u)
does not actually exist in the container:
I have no name!@0d9c6a272ae1:/home$
and thus does not have a home directory, which could be parsed by fc-cache
.
What's an elegant way to solve this problem?

The answer is as easy as adding
chown $UID output.pdf
to build.sh
and then passing docker an env-var instead of the user id:
docker run -e UID=$(id -u) --rm -t -v $(pwd):/home pandoc_container build.sh
