无法在 r shiny docker 中安装 devtools

Question

I'm trying to build a docker image for my shiny app. Below is my dockerfile . When I build my images, everything else seems fine, except I got error message Error in library(devtools): there is no package called 'devtools' Execution halted . I also tried devtools::install_github('nik01010/dashboardthemes') with no success. I have non clue why? What could go wrong? Do anyone know what is wrong with my dockerfile? Thanks a lot.

# Copy configuration files into the Docker image
COPY shiny-server.conf  /etc/shiny-server/shiny-server.conf
COPY /app /srv/shiny-server/

# Make the ShinyApp available at port 80
EXPOSE 80

# Copy further configuration files into the Docker image
COPY shiny-server.sh /usr/bin/shiny-server.sh

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

Answer 1

There are a few approaches you might try.

Easiest:

Use remotes::install_github instead of devtools . remotes has many fewer dependencies if you don't need the other functionality.

Second Easiest:

Use rocker/tidyverse image from Docker Hub instead of baseR image.

docker pull rocker/tidyverse

Change line 2:

FROM rocker/verse

Hardest:

Otherwise, you will need to figure out which dependencies you need to install inside your docker image before you can install devtools . It will likely be obvious if you try to install it interactively.

1. Make sure the container is running
2. Get the container name using docker ps
3. Start a shell with docker exec -it <container name> /bin/bash
4. Start R and try to install devtools interactively
