Feature request : add xz-utils package to image `pandoc/ubuntu-latex`

[michelou]

A Docker container created from image pandoc/ubuntu-late has the following TeX Live setup :

/opt/texlive/texdir/
/opt/texlive/texmf-local/

We want to generate a standalone PDF file from Markdown documents.

In our case we need to add ~10 TeX font packages from the TeX Live archive to directory texmf-local/ before running md2pdf, our wrapper script which calls the pandoc command line tool with the appropriate options (including fonts).

When building our Docker image on top of pandoc/ubuntu-latex we run the following command (among others) to install those packages, e.g. tcolorbox.tar.xz :

$ tar -C /opt/texlive/texmf-local/ -xf tcolorbox.tar.xz

Unfortunately the above command requires the Ubuntu package xz-utils to be installed in order to run successfully (i.e. xz tool must be on path).

In short :

1. Does image pandoc/ubuntu-latex feature another way to install private TeX packages ?
2. If not, we would welcome it if package xz-utils was added to pandoc/ubuntu-latex.

Not sure if this answers your question, but you might be interested in this example. It builds on top of the Alpine-based pandoc/latex image but would work just as well with pandoc/ubuntu-latex. Are the sources for your setup available online for us to take a look?

@jgm, can we move this issue over to pandoc/dockerfiles?

@tarleb Thanks for the link. So far my experiments with tlmgr were not successful (NB. my current solution works fine on MS Windows 10, MSYS2 and Ubuntu 18.04); I will have another try with it (hopefully to prove to myself I did something wrong with my first attempts 😉).

The sources for my setup should be available later this week; I plan to publish a PR to project lampepfl/dotty (Markdown files are in docs/docs/).

@jgm, can we move this issue over to pandoc/dockerfiles?

Fine with me but I don't think I can do it because I don't have the right privileges in the latter. Go ahead and transfer.

@tarleb I've pushed PR #11257 to project lampepfl/dotty.

Finally your example was helpful, thanks. My set up is now working (using tlmgr as in the example).

Here are the links you may be interested in :

• pandoc/Dockerfile
• docs/DOCKER.md (entry page is README.md).

Glad to hear that, and thanks for the links.

@jgm, I tried but couldn't transfer the issue either.
