Simple Docker image to convert Japanese Jupyter Notebook to PDF

TL;DR

If you want to convert Jupyter Notebook (possibly, with Japanese script included) to pdf, do the following

1. move to new directory
2. inside it, create the subdirectories ./notebooks and ./pdfs
3. save your notebook under the name ./notebooks/notebook.ipynb
4. run the command docker run nailbiter/jupyter-latex-pdf
5. pick up the generated pdf from ./pdfs/notebook.pdf

Purpose

In my work, I sometimes need to convert the Jupyter Notebook to PDF. While this is easy to do in general via jupyter nbconvert, if the Notebook contains Japanese script, experience shows,
that often the additional processing is required.

In my experience, the approach that works is to convert Notebook to tex file first, and then use XeTeX to create the PDF. However, this requires installing the number of big dependencies, most notably XeTeX and Japanese
fonts. In order to encapsulate these dependencies from contaminating the system, I have put up together simple Docker image, which does exactly that.

1. Dockerfile
