使用 docker 文件安装 R 包 [英] Install R packages using docker file

问题描述

我已经在我的 docker 文件中使用以下行安装了 R.请建议我现在如何指定要安装在我的 docker 文件中的软件包.

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

我正在做这样的事情:

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/')" 

这是正确的做法吗?

推荐答案

正如@Cameron Kerr 的评论所建议的，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/')" 

如果您相当确定没有包失败，请使用此单线 -

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/')"

如果你不使用 Base-R 镜像，你可以使用 rocker-org 的 r-ver 或 r-studio 或 tidyverse 图像.这是 repo.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

--error 标志是可选的，它使 install.packages() 如果包安装失败(这将导致 docker build 命令失败).默认情况下，install.packages() 只会抛出一个警告，这意味着即使安装包失败，Dockerfile 也可以构建成功.

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 基本上都是 为 install2.R 功能安装 littler 包

All rocker-org's basically installs the littler package for the install2.R functionality
