How to use renv with shiny-server in Docker

Hi there, I am trying to use renv with the rocker/shiny image. I pushed a minimal example to git, the Dockerfile looks like this:

FROM rocker/shiny:3.6.0

RUN Rscript -e 'install.packages(c("renv"),  dependencies = TRUE, repos="http://cran.rstudio.com/")'

ADD app /srv/shiny-server/app

WORKDIR /srv/shiny-server/app

RUN Rscript -e 'setwd("/srv/shiny-server/app"); source(".Rprofile"); renv::restore()'

EXPOSE 3838

CMD ["/usr/bin/shiny-server.sh"]

However, somehow, R does not find the installed librarys. In the Docker logs, I keep getting this error:

I based my Dockerfile in this renv vignette:


When just runnign some R script with a rocker/r-base image, this worked fine.

I found these resources on packrat with Shiny+Docker, but they don't seem applicable to renv, because of the changed way renv deals with libraries:


Does anyone have experience with this? I am grateful for any help!

I'm having the same problem, and have added it as an issue in the Renv repository here (issue #450).
