# - see https://github.com/rstudio/rmarkdown/blob/master/PANDOC.md

# - Use a version-stable tlnet archive CTAN repo from texlive.info
#   - here we consider a frozen TeXLive snapshot, corresponding to the TeXLive
#     release shipped as texlive-* in Ubuntu 22.04 jammy (2021.20220204-1: all)
ENV CTAN_REPO=https://www.texlive.info/tlnet-archive/2022/02/04/tlnet

# - It is important to also install all required LaTeX packages when building the image

## Script for re-installation of TinyTeX in the running container
#  - needed if at a certain point the "Remote repository is newer than local",
#    for non-version-stable TinyTeX installations
#  - this also (re-)executes (and therefore depends on) install_tinytex.sh
COPY docker/reinstall_tinytex.sh .

## Install major fixed R dependencies
#  - they will always be needed and we want them in a dedicated layer,
#    as opposed to getting them dynamically via `remotes::install_local()`
