Workflow for creating modified images i.e. different filters

Hi All,

I'm new to pandoc and newer to Haskell.

What would be the idiomatic way of creating a custom image with extra filters, i.e. pandoc-plot?

I envision a DOCKERFILE as follows but I haven't had much luck so far.

FROM pandoc/extra:latest-ubuntu

RUN apt-get update
RUN apt-get install -y python3 python3-plotly python3-matplotlib
RUN apt-get install -y cabal-install
RUN cabal update
RUN cabal install pandoc-plot

Then I want to run the image including the filters in the workflow.

Any help would be appreciated.

The above fails because cabal isn't installed in the container; we use cabal to build the binaries, but don't ship it in the final image.

I would probably use conda or a similar install method for pandoc-plot, or, if possible, use a Lua filter like diagram. The Lua filter is just a single script file and therefore easy to install, but the list of supported graphing engines is different.

FYI, I downloaded the executable directly off github as suggested by @LaurentRDC and it worked.

Thank you.
