使用 shinyproxy 部署 shiny - 没有应用程序显示

Question

我开发了一个闪亮的应用程序，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 功能的包装器。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

    access-groups: scientist

logging:
  file:
    shinyproxy.log

当我启动 java shinyproxy.jar 并使用我公开的端口访问 url 时，我看到了一个登录掩码。我使用简单身份验证登录（从 shinyproxy.log 成功登录）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正常。

谢谢

Answer 1

Dzimitry 是对的。这是一个打字错误：scientists over scientist.

Answer 2

在application.yml允许的用户组有一个错误（应该是scientists over scientist）：

 access-groups: scientists
