shiny - 使用 shinyproxy 部署 shiny - 没有应用程序显示

Question

我开发了一个 Shiny 的应用程序，我正在尝试使用 shinyproxy 进行首次轻量级部署。所有安装似乎都很好。我已经安装了 docker，java。

我认为构建一个包装应用程序和其他功能的包是个好主意。所以我开发了一个包 (CI)，CI::launch_application 基本上是 shiny 包的 RunApp 函数的包装器。这是代码:

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

我用这个 Dockerfile 成功构建了 docker 镜像

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()"]

这是我的application.yml文件

当我启动 java shinyproxy.jar 并访问带有我公开的端口的 url 时，我看到了一个登录掩码。我使用简单例份验证登录(从 shinyproxy.log 登录成功)但既没有显示应用程序也没有显示应用程序列表。当我在本地启动应用程序时，一切都很好。

谢谢

application.yml 中允许的用户组有一个打印错误(应该是 scientists over scientist):

 access-groups: scientists
