Deploy shiny with shinyproxy - no app showing

问题

I've developed a shiny app and i'm trying to do a first lightweight deploy using shinyproxy. All installation seems fine. I've installed docker, java.

I thought that building a package that wraps the app and other function would be a good idea. So I developed a package (CI) and CI::launch_application is basically a wrapper around RunApp function of shiny package. This is the code:

launch_application <- function(launch.browser = interactive(), ...) {
  runApp(
    appDir = system.file("app", package = "CI"),
    launch.browser = launch.browser,
    ...
  )
}

I succesfully built the docker image with this Dockerfile

FROM rocker/r-base:latest

## Install required dependencies
RUN apt-get update \
  && apt-get install -y --no-install-recommends \
    ## for R package 'curl'
    libcurl4-gnutls-dev \
    apt-utils \
    ## for R package 'xml2'
    libxml2-dev \
    ## for R package 'openssl'
    libssl-dev \
    zlib1g-dev \
    default-jdk \
    default-jre \
  && apt-get clean \
  && R CMD javareconf \
  && rm -rf /var/lib/apt/lists/




## Install major fixed R dependencies
#  - they will always be needed and we want them in a dedicated layer,
#    as opposed to getting them dynamically via `remotes::install_local()`
RUN install2.r --error \
  shiny \
  dplyr \
  devtools \
  rJava \
  RJDBC

# copy the app to the image
RUN mkdir /root/CI
COPY . /root/CI

# Install CI
RUN install2.r --error remotes \
  && R -e "remotes::install_local('/root/CI')"

# Set host and port

RUN echo "options(shiny.port = 80, shiny.host = '0.0.0.0')" >> /usr/local/lib/R/Rprofile.site

EXPOSE 80

CMD ["R", "-e", "CI::launch_application()"]

This is my application.yml file

    container-image: company/image
    access-groups: scientist

logging:
  file:
    shinyproxy.log

When I launch java shinyproxy.jar and i visited the url with the port I exposed, I see a login mask. I logged in with simple authentication ( login is successful from shinyproxy.log) but neither an app is showing nor a list of app. When I launch the app locally everything is fine.

Thanks

回答1:

There is a misprint in the allowed user group in application.yml (should be scientists over scientist):

 access-groups: scientists

回答2:

Dzimitry is right. It was a typo error: scientists over scientist.
