Launch shiny on bioconductor docker image

[ryamy]

Thanks for your great library, I enjoy using sangeranalyseR.

Now I am using sangeranalyseR on bioconductor-docker container. Could you kindly tell me how to access shinyapp launched via launchApp() on bioconducotr docker? Shiny app seems to wait on a different port in each launch. Is it possible to fix the shiny app waiting port? I would like to EXPOSE shiny port on docker container, but I can not because the port is different in each launch.

Thank you!

R session log is following:

From bioconductor/bioconductor_docker:devel

EXPOSE 8787 # rstudio

# EXPOSE xxxx # which port should I specify for launchApp()?

By setting shiny.port and shiny.host on R session, I can access the shiny ui from my localhost. Thanks!!

# in this case
options(shiny.port = 3838, shiny.host = '0.0.0.0')
