我将使用'mxnet'软件包的闪亮应用程序停靠。经过大量的努力，我得出结论，我需要构建和安装软件包，而不是仅仅通过dmlc repos安装它。下面是我试图构建和安装mxnet的简化dockerfile：
FROM r-base:latest
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 shiny server
RUN wget --no-verbose https://s3.amazonaws.com/rstudio-shiny-server-os- build/ubuntu-12.04/x86_64/VERSION -O "version.txt" && \
VERSION=$(cat version.txt) && \
wget --no-verbose "https://s3.amazonaws.com/rstudio-shiny-server-os- build/ubuntu-12.04/x86_64/shiny-server-$VERSION-amd64.deb" -O ss-latest.deb && \
gdebi -n ss-latest.deb && \
rm -f version.txt ss-latest.deb
# Here comes the installation of other required packages:

#*** Here comes the problamatic bit: building Installing mxnet
RUN sudo apt-get update
RUN sudo apt-get install -y build-essential git libatlas-base-dev libopencv-dev
RUN git clone --recursive https://github.com/dmlc/mxnet
RUN cd mxnet; make -j$(nproc)
RUN Rscript -e "install.packages('devtools', repo = 'https://cran.rstudio.com')"
RUN cd R-package
RUN Rscript -e "library('devtools'); library('methods'); options(repos=c(CRAN='https://cran.rstudio.com')); install_deps(dependencies = TRUE)"
RUN cd ..
RUN make rpkg
COPY shiny-server.conf /etc/shiny-server/shiny-server.conf
COPY /myapp/* /srv/shiny-server/
EXPOSE 80
COPY shiny-server.sh /usr/bin/shiny-server.sh
CMD ["/usr/bin/shiny-server.sh"]
运行之后，我收到一条错误说：
can not cd to R-Package
有任何帮助吗？
答案 0 :(得分：1)
尝试
RUN cd mxnet; make -j$(nproc)\
&& Rscript -e "install.packages('devtools', repo = 'https://cran.rstudio.com')"
您的RUN cd ..将无法达到您所期望的效果，与打开终端，执行cd abc/def以及在/ home / $ USER中的另一个终端执行cd ..相同}，你不会在abc。
您应该对RUN命令进行分组，以限制图像中的图层数量，请参阅
https://docs.docker.com/engine/userguide/eng-image/dockerfile_best-practices/
还检查Dockerfile中的WORKDIR指令
https://docs.docker.com/engine/reference/builder/#workdir
您可以通过启动shell
来检查正确完成（或不完成）的操作 docker run -it your_image /bin/bash
然后检查是否存在。
