如何使用R&构建Dockerfile爪哇 [英] How to build Dockerfile with R & Java

问题描述

我正在尝试构建一个使用RJava包运行R的Docker容器.我尝试了以下代码:

I'm trying to build a Docker container that runs R with the package RJava. I have tried the following code:

# Install R version 3.6.3
FROM rocker/tidyverse:3.6.3

# Make ~/.R
RUN mkdir -p $HOME/.R

# Install Ubuntu packages && then R packages
RUN install2.r --error \
         lubridate magrittr RPostgres DBI broom rlang rJava

但是我得到以下信息:软件包"rJava"的安装退出状态为非零.

However I get the following: installation of package ‘rJava’ had non-zero exit status.

任何人都可以帮我这个忙.我在想这也许是因为未安装Java.有谁知道如何在此docker容器上安装Java?

Can anyone help me with this. I'm thinking that maybe it is because Java is not installed. Does anyone know how to install Java on this docker container?

我尝试按照我发现的另一篇文章将以下内容添加到我的dockerfile中，但是出现错误消息存储库' http://ppa.launchpad.net/webupd8team/java/ubuntu focus Release'没有发布文件:

I've tried adding the following to my dockerfile as per another post I found however I get the error saying 'The repository 'http://ppa.launchpad.net/webupd8team/java/ubuntu focal Release' does not have a Release file:

# Install "software-properties-common" (for the "add-apt-repository")
RUN apt-get update && apt-get install -y \
    software-properties-common

# Add the "JAVA" ppa
RUN add-apt-repository -y \
    ppa:webupd8team/java

# Install OpenJDK-8
RUN apt-get update && \
    apt-get install -y openjdk-8-jdk && \
    apt-get install -y ant && \
    apt-get clean;

# Fix certificate issues
RUN apt-get update && \
    apt-get install ca-certificates-java && \
    apt-get clean && \
    update-ca-certificates -f;

# Setup JAVA_HOME -- useful for docker commandline
ENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64/
RUN export JAVA_HOME

我是Docker的新手，在此方面提供的任何帮助将不胜感激.

I'm new to docker and any help with this would be much appreciated.

推荐答案

rocker 图像基于 debian ，而不是 ubuntu .具体来说，它是 Debian GNU/Linux 10(破坏者).在该版本中，您可以通过 apt 安装软件包 openjdk-11-jdk 来安装 java ，而无需添加任何存储库用于 openjdk-8-jdk .

The rocker images are based on debian, not ubuntu. Specifically it is Debian GNU/Linux 10 (buster). With that version, you can install java by installing the package openjdk-11-jdk via apt and you don't need to add any repositories for openjdk-8-jdk.

因此，一个可以正常工作的dockerfile会安装 rJava :

So a working dockerfile that installs rJava:

FROM rocker/tidyverse:3.6.3

RUN apt-get update && \
    apt-get install -y openjdk-11-jdk && \
    apt-get install -y liblzma-dev && \
    apt-get install -y libbz2-dev

RUN Rscript -e "install.packages('rJava')"

注意: liblzma-dev 和 libbz2-dev 是用于编译 rJava 的其他系统依赖项.

Note: liblzma-dev and libbz2-dev are additional system dependencies for compiling rJava.
