Error when flexdashboard.Rmd is deployed via shiny proxy

ShinyProxy
1

Hi all,

I have build a Dockerimage with CMD [“R”, “-e”, “rmarkdown::run(file=‘bin/Dashboard_kursnet_ranking.Rmd’, shiny_args = list(port = 3838, host = ‘0.0.0.0’))”]

as last line and as well as put this command in the application.yml. The proxy image runs and I can see the name of my App, however it does not work. I get Error:image

This is my flexdashboard dockerfile:

FROM rocker/shiny-verse:latest

RUN  echo 'install.packages(c("dplyr","dbplyr","DBI","DT","plotly","flexdashboard","lubridate"), \
        repos="http://cran.us.r-project.org", \
        dependencies=TRUE)' > /tmp/packages.R \
        && Rscript /tmp/packages.R
	
	

COPY Dashboard_kursnet_ranking.Rmd       /bin/Dashboard_kursnet_ranking.Rmd   

# make all app files readable (solves issue when dev in Windows, but building in Ubuntu)
RUN chmod -R 755 /bin

EXPOSE 3838

CMD ["R", "-e", "rmarkdown::run(file='bin/Dashboard_kursnet_ranking.Rmd', shiny_args = list(port = 3838, host = '0.0.0.0'))"]

This is my application.yml file:

  title: proxy_dashboards
  hide-navbar: false
  landing-page: /
  
  port: 3838
  docker:
    internal-networking: true
  specs:
  - id: 01_kursnet_dashboard
    display-name: Kursnet Dashboard

    container-cmd: ["R", "-e", "rmarkdown::run(file='root/Dashboard_kursnet_ranking.Rmd', shiny_args = list(port = 3838, host = '0.0.0.0'))"]
    container-image: kursnetdashboard
    container-network: kt-net
    container-env:
      user: "shiny"
      environment:
        - APPLICATION_LOGS_TO_STDOUT=false 

logging:
  file:
   shinyproxy.log

EDIT: I start the shiny proxy docker container with:
docker run -d -v /var/run/docker.sock:/var/run/docker.sock --net kt-net -p 3838:3838 shiny_proxy
I included the test shiny app from shiny proxy in the application.yml. This test app works fine when I access it via localhost:3838:

 - id: 02_test
    display-name: test
