Ok, well I built a custom docker image based on:
pandoc/latex:2.14.0.3

Then I did this in my custom Docker container, hoping I'd get at least some 
fonts installed. It appears to install quite a few, and exited normally.
tlmgr install collection-fontsrecommended

Then in my custom Docker container CLI, I do this, I look for Helvetica, 
and get this:
/opt/texlive/texmf-local # tlmgr search --all "fonts" | grep helv
helvetic - URW "Base 35" font pack for LaTeX
helvetic:
    texmf-dist/fonts/afm/adobe/helvetic/phvb8a.afm
    texmf-dist/fonts/afm/adobe/helvetic/phvb8an.afm
    texmf-dist/fonts/afm/adobe/helvetic/phvbo8a.afm
    texmf-dist/fonts/afm/adobe/helvetic/phvbo8an.afm
    texmf-dist/fonts/afm/adobe/helvetic/phvr8a.afm
    ...etc

I've pushed this custom Docker image to my repo on Docker Hub 
<https://hub.docker.com/repository/docker/tojdk/pandoc-latex-fonts>, and my 
GitHub Action in another repo loads my custom Docker image, and calls 
convert_via_pandoc with this arg
 -V fontfamily=helvet

While it runs my custom Docker image, and converts the PDF, I still don't 
get Helvetica, I still get Latin Modern in the PDF. What am I doing wrong?

*Note:* I can tell that "helvet" is the desired spelling. Since if I 
misspell it intentionally, or feed that -V fontamily argument some bogus 
font family name, the conversion will fail on the missing '.sty'.

Is there something I still have to configure in my custom Docker container 
image to use that installed Helvetica font? Or should that tlmgr install 
collection-fontsrecommended have been sufficient?

Thanks
