I am developing an R package for a Shiny App and containerising this with Docker, and I've used Golem's add_dockerfile() command to create the Dockerfile below. (I've removed most of the dependencies for brevity.) Unfortunately, it doesn't build. Please could someone help?
Dockerfile
FROM rocker/r-ver:4.1.1
RUN apt-get update && apt-get install -y git-core libcurl4-openssl-dev libgit2-dev libicu-dev libssl-dev libxml2-dev make pandoc pandoc-citeproc unixodbc-dev && rm -rf /var/lib/apt/lists/*
RUN echo "options(repos = c(CRAN = 'http://cran.rstudio.com/'), download.file.method = 'libcurl', Ncpus = 4)" >> /usr/local/lib/R/etc/Rprofile.site
RUN R -e 'install.packages("remotes")'
RUN Rscript -e 'remotes::install_version("rlang",upgrade="never", version = "0.4.11")'
RUN Rscript -e 'remotes::install_version("glue",upgrade="never", version = "1.4.2")'
RUN mkdir /build_zone
ADD . /build_zone
WORKDIR /build_zone
RUN R -e 'remotes::install_local(upgrade="never")'
RUN rm -rf /build_zone
EXPOSE 3838
CMD R -e "options('shiny.port' = 3838,shiny.host='0.0.0.0');exampleApp::run_app()"
Error message
When I try to build this with docker build -t "test_image" ., I get the following error message:
=> ERROR [45/46] RUN R -e 'remotes::install_local(upgrade="never")' 17.1s

So it looks like the remotes package isn't found after the working directory is moved to /build_zone. Can anyone explain why this might be happening? I have tried a workaround and I managed to get the image to build but then when I tried to run it, it says that my package (exampleApp) is not found either. I don't have a good enough understanding of the Docker commands to know what's going on.
Thank you!
