This is with Dockerfile.basic

The Dockerfile is outdated. You can fix it by simply going into the Dockerfile and change
ENV PATH="/usr/local/texlive/2017/bin/x86_64-linux:${PATH}"
to
ENV PATH="/usr/local/texlive/2019/bin/x86_64-linux:${PATH}".

Will this break again in 2020? What is the rational of putting a year in the path and how do I best lock this down?

I'm still seeing this as of October 2019.

@blang Can you maybe update the repo/dockerfile here?
