ERROR: cannot extract package from ‘shinyproxy-2.1.0.tar.gz’

Based on Dockerfile of shinyproxy-demo

I’m not able to install shinyproxy-2.1.0.tar.gz using the command R CMD INSTALL

Warning in untar2(tarfile, files, list, exdir, restore_times) :
skipping pax global extended headers
ERROR: cannot extract package from ‘shinyproxy-2.1.0.tar.gz’

I want to use shinyproxy inside Docker container. But It seems to be necessary to install shinyproxy command inside the shiny docker image

Is there any alternative ?

Hi @socia_net,

You are mixing up things, because there is no such thing as an R package shinyproxy-2.1.0.tar.gz to be installed with R CMD INSTALL . We only distribute jar files of ShinyProxy, currently shinyproxy-2.2.0.jar (see If you want to run ShinyProxy containerized, see the configuration examples at Please read the getting started guide and deploying apps guidance to get started.

You’re right. It took me a week to find out why my shiny app (inside docker container) is not working with containerized Shinyproxy. I was so confused with the Dockerfile script on the shinyproxy-demo :

# install shinyproxy package with demo shiny application
COPY shinyproxy_0.0.1.tar.gz /root/
RUN R CMD INSTALL /root/shinyproxy_0.0.1.tar.gz
RUN rm /root/shinyproxy_0.0.1.tar.gz

But finally managed to have it displayed !
keep up the great work !
