R tinytex cannot connect to CTAN mirrors during docker build

I'm trying to build a Docker container to develop PDF reports for download through an R Shiny app. As such, I am installing TinyTeX to manage all the dependencies. I have my build setup through a Dockerfile and a dummy report at the end that should run and initialize any files needed to make it work. I have tried this on both hub.docker.com and my local machine with no success. My local install of RStudio runs the Shiny apps successfully.

My minimal Dockerfile is:

FROM rocker/r-ver:4.3.2

RUN apt-get update && apt-get install -y \
    sudo \
    pandoc \
    pandoc-citeproc \
    && apt-get update && apt-get upgrade -y\
    && apt-get clean && apt-get autoremove --purge

RUN R -e "install.packages(c('rmarkdown','tinytex')); tinytex::install_tinytex(force=TRUE)"

COPY dummy.Rmd /root/dummy.Rmd

RUN R -e "rmarkdown::render('/root/dummy.Rmd',output_file='dummy.pdf')"

and dummy.Rmd is

Sample Text

No matter which mirror I set, I am getting some variation of the message:

cannot contact mirror.ctan.org, returning a backbone server!
/root/.TinyTeX/bin/x86_64-linux/tlmgr: TLPDB::from_file could not initialize from: https://www.ctan.org/tex-archive/systems/texlive/tlnet/tlpkg/texlive.tlpdb
/root/.TinyTeX/bin/x86_64-linux/tlmgr: Maybe the repository setting should be changed.
/root/.TinyTeX/bin/x86_64-linux/tlmgr: More info: https://tug.org/texlive/acquire.html
! LaTeX Error: File `multirow.sty' not found.
! Emergency stop.

whether I am running this build locally or on the docker hub server.

tinytex::is_tinytex() returns TRUE.

Edit: Fixed syntax error and dependency error, but does not reproduce the error.

Solution

  • Konrad Rudolph's comment on datawookie's answer was correct; the tidyverse image adds a lot of other dependencies. I simplified the image a lot by using a rocker script still in the image.

    Dockerfile:

    FROM rocker/r-ver:4.3.2

RUN apt-get update && apt-get install -y \
    sudo \
    pandoc \
    pandoc-citeproc \
    && apt-get update && apt-get upgrade -y\
    && apt-get clean && apt-get autoremove --purge

# Copied these next lines from rocker scripts to properly install texlive
ENV CTAN_REPO=https://mirror.ctan.org/systems/texlive/tlnet
ENV PATH=$PATH:/usr/local/texlive/bin/linux
RUN /rocker_scripts/install_texlive.sh

RUN R -e "install.packages(c('rmarkdown','tinytex'))"

COPY dummy.Rmd .

#The dummy markdown should automatically install all the needed dependencies for further .Rmd files
RUN R -e "rmarkdown::render('dummy.Rmd')"

    Thank you all for your help! I'm not sure what was causing the original problem, but it was most likely a misconfigured installation. And my own inexperience (read incompetence). I apologize for not submitting a runnable reduced problem that replicated the issue, but thank you for helping me resolve it regardless.
