在与3838不同的端口上运行Shiny-server

Question

我正在容器中部署Shiny-server。缺省情况下，Shiny-server监听端口3838，下面是shiny-server.conf中的一段

# Instruct Shiny Server to run applications as the user "shiny"
run_as shiny;

# Define a server that listens on port 3838
server {
  listen 3838;

我想将此端口更改为80。显然，我可以启动容器实例，登录到它，并更改它，但我想在Dockerfile中更改它。

FROM rocker/shiny:3.5.1

RUN apt-get update && apt-get install libcurl4-openssl-dev libv8-3.14-dev -y &&\
  mkdir -p /var/lib/shiny-server/bookmarks/shiny

# Download and install library
RUN R -e "install.packages(c('shinydashboard', 'shinyjs', 'V8'))"

# copy the app to the image COPY shinyapps /srv/shiny-server/
COPY "reports" "/srv/shiny-server/sample-apps/reports/"

# make all app files readable (solves issue when dev in Windows, but building in Ubuntu)
RUN chmod -R 755 /srv/shiny-server/

EXPOSE 80
CMD ["/usr/bin/shiny-server.sh"] 

Dockerfile中的最后一行有命令行选项吗？

Answer 1

添加

RUN sed -i -e 's/\blisten 3838\b/listen 80/g' /path/to/shiny-server.conf

所以也许最终会是这样的：

FROM rocker/shiny:3.5.1

RUN apt-get update && apt-get install libcurl4-openssl-dev libv8-3.14-dev -y &&\
  mkdir -p /var/lib/shiny-server/bookmarks/shiny

# Download and install library
RUN R -e "install.packages(c('shinydashboard', 'shinyjs', 'V8'))"

# copy the app to the image COPY shinyapps /srv/shiny-server/
COPY "reports" "/srv/shiny-server/sample-apps/reports/"

# make all app files readable (solves issue when dev in Windows, but building in Ubuntu)
RUN chmod -R 755 /srv/shiny-server/

RUN sed -i -e 's/\blisten 3838\b/listen 80/g' /path/to/shiny-server.conf

EXPOSE 80
CMD ["/usr/bin/shiny-server.sh"]

(我知道，如果不压缩多个层，效率可能会很低，如果您想要将sed行与前面的RUN命令组合在一起，请注意这一点。如果这是一个问题，您可能希望组合更多的RUN行。)
