使用Docker文件安装R软件包 [英] Install R packages using docker file

问题描述

我在docker文件中使用以下行安装了R。请建议我现在如何指定要在我的docker文件中安装的软件包。

I have installed R using below line in my docker file. Please suggest how do I specify now packages to be installed in my docker file.

RUN yum -y install R-core R-devel

我正在执行以下操作：

RUN R -e "install.packages('methods',dependencies=TRUE, repos='http://cran.rstudio.com/')"\
    && R -e "install.packages('jsonlite',dependencies=TRUE, repos='http://cran.rstudio.com/')" \
    && R -e "install.packages('tseries',dependencies=TRUE, repos='http://cran.rstudio.com/')" 

这是正确的方法吗？

推荐答案

如@Cameron Kerr的建议评论，Rscript不会给您构建失败。
到目前为止，推荐的方法是按照问题的建议进行操作。

As suggested by @Cameron Kerr's comment, Rscript does not give you a build failure. As of now, the recommended way is to do as the question suggests.

RUN R -e "install.packages('methods',dependencies=TRUE, repos='http://cran.rstudio.com/')"
RUN R -e "install.packages('jsonlite',dependencies=TRUE, repos='http://cran.rstudio.com/')"
RUN R -e "install.packages('tseries',dependencies=TRUE, repos='http://cran.rstudio.com/')" 

如果您确定没有包装失败，请使用这种单线-

If you're fairly certain of no package failures then use this one-liner -

RUN R -e "install.packages(c('methods', 'jsonlite', 'tseries'),
                           dependencies=TRUE, 
                           repos='http://cran.rstudio.com/')"

编辑：：如果您不使用Base-R图像，则可以使用 rocker-org 的 r-ver 或 r-studio 或 tidyverse 图片。这是存储库。这是一个示例Dockerfile-

If you're don't use the Base-R image, you can use rocker-org's r-ver or r-studio or tidyverse images. Here's the repo. Here's an example Dockerfile -

FROM rocker/tidyverse:latest

# Install R packages
RUN install2.r --error \
    methods \
    jsonlite \
    tseries

-错误标志是可选的，它使 install.packages（）抛出如果软件包安装失败，将导致错误（这将导致 docker build 命令失败）。默认情况下， install.packages（）仅引发警告，这意味着即使文件安装失败，Dockerfile也可以成功构建。

The --error flag is optional, it makes install.packages() throw an error if the package installation fails (which will cause the docker build command to fail). By default, install.packages() only throws a warning, which means that a Dockerfile can build successfully even if it has failed to install the package.

所有 rocker-org 基本上是安装 littler 包 > install2.R 功能
