I am new to docker and ShinyProxy. I was following the steps from https://www.shinyproxy.io/. All is working fine with the Hello-world and 06_tabset apps. Then I have build the Image for the Euler App which is not working when opening the app from the browser. 

Error
Status code: 500

Message: Failed to start container

Stack Trace: 
eu.openanalytics.containerproxy.ContainerProxyException: Failed to start container

EDIT:

The actual error is:

 Caused by: com.spotify.docker.client.exceptions.DockerRequestException: Request error: POST http://localhost:2375/containers/create: 400, body: {"message":"No command specified"}

also when I try to just run the App it is not working with:

sudo docker run -p 3838:3838 openanalytics/shinyproxy-demo R -e 'shiny::runApp('/root/euler')'

the Error I get is:

shiny::runApp(/root/euler)
Error: unexpected '/' in "shiny::runApp(/"
Execution halted

and after changing it to:

sudo docker run -p 3838:3838 openanalytics/shinyproxy-demo R -e 'shiny::runApp('root/euler')'

I get this:

Error in as.shiny.appobj(appDir) : object 'root' not found
Calls: <Anonymous> -> as.shiny.appobj
Execution halted

I think the problem could be that the Image is openanalytics/shinyproxy-template and not openanalytics/shinyproxy-demo.

try:

 sudo docker run -p 3838:3838 openanalytics/shinyproxy-template R -e 'shiny::runApp("/root/euler")'

    now it is working outside of ShinyProxy but the Error Status code: 500 Message: Failed to start container is still there :( – mi93 Jul 12 '19 at 12:16

just try this :

sudo docker run -p 3838:3838 openanalytics/shinyproxy-demo R -e 'shiny::runApp("/root/euler")'

the problem is that you use ' twice in your command that is why the app sees that as 'shiny::runApp(/'

and make sure that Shiny application exists at the path "/root/euler".
