使用 docker 运行 Rstudio-connect

Question

我尝试使用 Docker 安装 Rstudio-connect。我尝试使用 ubuntu、centos 和 Rocker/tidyverse 基本图像。没有成功...

这是我制作的 Dockerfile。

FROM ubuntu
RUN apt-get update
RUN apt-get install -y gdebi-core
RUN apt-get install -y build-essential libcurl4-gnutls-dev libxml2-dev libssl-dev
RUN apt-get install -y r-base
RUN apt-get autoclean
RUN apt-get clean
RUN apt-get install -y texlive-full
RUN apt-get install -y libgmp10-dev  libgsl0-dev    libnetcdf-dev   netcdf-bin  libdigest-hmac-perl  libgmp-dev   libgmp3-dev  libgl1-mesa-dev   libglu1-$
RUN apt-get install -y  net-tools
RUN apt-get install -y procps

RUN gdebi -n rstudio-connect.deb
COPY rstudio-connect-*-amd64.deb rstudio-connect.deb
EXPOSE 3939

使用此容器，我无法运行 rstudio connect。我有这个错误：“没有检测到已知的初始化系统。” 从这个脚本 /var/lib/dpkg/info/rstudio-connect.postinst 无论如何我尝试手动启动

    systemctl enable rstudio-connect.service
    systemctl stop rstudio-connect.service
    systemctl start rstudio-connect.service
    cp /opt/rstudio-connect/packaging/init/upstart/rstudio-connect.conf /etc/init/rstudio-connect.conf

但我有这个错误：

> root@f5a1b89e68f2:/# systemctl enable rstudio-connect.service Created
symlink
> /etc/systemd/system/multi-user.target.wants/rstudio-connect.service,
pointing to /lib/systemd/system/rstudio-connect.service.
> root@f5a1b89e68f2:/# systemctl start rstudio-connect.service Failed to
connect to bus: No such file or directory

如果我直接运行 ./connect

这是我得到的：

> root@f5a1b89e68f2:/opt/rstudio-connect/bin# ./connect --config /etc/rstudio-connect/rstudio-connect.gcfg

但是 R 存在，并且 rstudio-connect 用户可以运行它！

任何的想法 ？

Connect 使用沙箱，该沙箱使用与 Docker 相同的机制来隐藏可执行用户代码的某些目录。您需要在“特权”模式下运行容器。尝试做docker run --privileged ...
