Hi Team,

this app is great, thank you for developing it!

I’m trying to add custom shiny applications to a containerized docker engine based on this tutorial: [https://github.com/openanalytics/shinyproxy-config-examples/tree/master/02-containerized-docker-engine](https://github.com/openanalytics/shinyproxy-config-examples/tree/master/02-containerized-docker-engine)

In this case the shinyproxy.jar is also containerized and communicates on a bridge network with the apps (in an other image). The tutorial is straightforward and works flawlessly for the demo applications which are built into the shinyproxy-demo image already. But I’m not able to add more apps…

In this scenario, the apps have to be converted into shinyproxy functions (if I understood correctly), like shinyproxy::run\_01\_hello(). This is done via the [shinyproxy\_0.0.1.tar.gz] installation inside the shinyproxy-demo image (R CMD INSTALL …tar.gz). It copies the files from the site-library/shiny/example folder to a temp folder.

I added new app.R files to the image, into the site-library folder. The build runs successfully, apps are converted and referenced in the application.yml. The new apps are listed but not loaded… Probably I missed something during the package installation when apps are converted into shinyproxy functions…

If anyone…  
Thanks in advance,  
Imre

Hi Imre,

There might be some confusion due to the fact that the demo R package is also called `shinyproxy`… In fact this is just an R package that contains two example shiny applications and functions to run them. For your own application you don’t have to wrap them in an R package, and you don’t need to use R package `shinyproxy`. So you would need to copy your application files (or package) and then adjust the RUN command to be something like `shiny::runApp("/path/to/app")` instead of `shinyproxy::run_01_hello()`.  
Hope this helps.

That is much simplier in this case. Thanks mnazarov!
