docker - 如何找到Shiny-Server可执行文件并在Shiny-server.sh中引用它？

Question

我的docker镜像构建似乎进行得很好，但是，我在使用 Shiny 的服务器可执行文件时遇到问题。主要地，shiny-server可执行文件在shiny-server.sh中被引用如下:

#!/bin/sh

# Make sure the directory for individual app logs exists
  mkdir -p /var/log/shiny-server 
chown shiny.shiny /var/log/shiny-server

exec shiny-server >> /var/log/shiny-server.log 2>&1

上面的代码对我不起作用(不知道为什么)，所以我不得不将其更改为这种方式:

#!/bin/bash

# Make sure the directory for individual app logs exists
mkdir -p /var/log/shiny-server
chown shiny.shiny /var/log/shiny-server

if [ "$APPLICATION_LOGS_TO_STDOUT" = "false" ];
then
    exec shiny-server 2>&1
else
    # start shiny server in detached mode
    exec shiny-server 2>&1 &

    # push the "real" application logs to stdout with xtail
    exec xtail /var/log/shiny-server/
fi

但是，出现以下错误:

$ docker run -p 80:8080 fitfarmz3

*** warning - no files are being watched ***
/usr/bin/shiny-server.sh: line 12: shiny-server: No such file or directory

将不胜感激如何解决此问题。

这里我包括了dockerfile:

FROM r-base:3.5.0

# Install Ubuntu packages
RUN apt-get update && apt-get install -y \
    sudo \
    gdebi-core \
    pandoc \
    pandoc-citeproc \
    libcurl4-gnutls-dev \
    libcairo2-dev/unstable \
    libxt-dev \
    libssl-dev

# Download and install ShinyServer
RUN wget --no-verbose https://download3.rstudio.org/ubuntu-14.04/x86_64/shiny-server-1.5.7.907-amd64.deb && \
    gdebi shiny-server-1.5.7.907-amd64.deb


# Install R packages that are required
RUN R -e "install.packages(c('Benchmarking', 'plotly', 'DT'), repos='http://cran.rstudio.com/')"
RUN R -e "install.packages('shiny', repos='https://cloud.r-project.org/')"

# Copy configuration files into the Docker image
COPY shiny-server.conf  /etc/shiny-server/shiny-server.conf
COPY /app /srv/shiny-server/

# Make the ShinyApp available at port 80
EXPOSE 80

# Copy further configuration files into the Docker image
COPY shiny-server.sh /usr/bin/shiny-server.sh

CMD ["/usr/bin/shiny-server.sh"]

Answer 1

因此出于某种原因，gdebi没有安装shiny-server。您可以通过以下方式在Dockerfile中安装它:

运行wget --no-verbose https://download3.rstudio.org/ubuntu-14.04/x86_64/shiny-server-1.5.7.907-amd64.deb && \
dpkg -i Shiny 服务器1.5.7.907-amd64.deb

为我工作。希望能帮助到你!
