Lualatex

[brokenpylons]

Lualatex uses a cache folder which is not accessible if you change the user to something else than root.

The error:

quiting: fix your writable cache path

My fix:

RUN chmod 1777 /var/lib/texmf

This changes the permissions so any user can write to the cache folder. The location of the cache folder is specified by the TEXMFCACHE environment variable. More info:

On second thought, this is probably better:

ENV TEXMFCACHE /tmp/texmf/

I made a docker file:

• docker-lualatex
• docker-lualatex-build

The first version includes only the packages needed to run lualatex. The size is 316MB (116MB on dockerhub), which is the lowest I could get without mucking with vanilla texlive (still way better than 3GB+ full image). The second additionally includes build tools (latexmk and make).
