如何在Alpine中安装R 3.4.4 [英] How to install R 3.4.4 in alpine

问题描述

我正在尝试在我的docker高山映像中安装R.之前我确实使用

I am trying to install R in my alpine image of docker. Earlier I did install it in my ubuntu image using

运行apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9 \&&add-apt-repository'deb [arch = amd64，i386] https://cran.rstudio.com/bin/linux/ubuntu xenial/'\&&apt-get update \&&&apt-get install -y r-base

在任何地方我都找不到如何在高山中安装它.任何帮助将不胜感激.

Nowhere I could find how to install it in alpine. Any help would be appreciated.

我的基本映像是python:3.7-alpine

My base image is python:3.7-alpine

推荐答案

R在Alpine社区存储库中可用，因此只需安装正确的

R is available in Alpine community repositories, so it's just a matter of installing the proper package:

apk加R

对于更紧凑的图像，如果您不需要专门的Python，则可以从原始的Alpine图像开始，例如 alpine:3.9 .

For a more compact image you could start off a vanilla Alpine image, such as alpine:3.9, if you don't need Python specifically.

Alpine上可用的最新R版本是3.5.1.最接近3.4.4的是3.4.2，该版本在Alpine V3.7中可用.在这种情况下，请启动Alpine V3.7:

The latest R version available on Alpine is 3.5.1. The closest to 3.4.4 is 3.4.2, which is available in Alpine V3.7. In that case, start off Alpine V3.7:

$ docker run -it alpine:3.7 
/ # apk add R

如果您确切需要R版本3.4.4，则可能必须从源代码进行构建.幸运的是，Artem Klevtsov提供了一个出色的现成的Dockerfile，它可以做到:
https://github.com/artemklevtsov/r-alpine/blob/master/release/Dockerfile

If you need R version 3.4.4 exactly, you may have to build it from source. Fortunately, there is an excellent ready made Dockerfile by Artem Klevtsov which does just that:
https://github.com/artemklevtsov/r-alpine/blob/master/release/Dockerfile

只需将R版本字符串替换为3.4.4并构建映像-效果很好.

Simply replace the R version string to 3.4.4 and build the image - works great.

使用特定R版本(该版本不适用于本机Alpine)的另一个选项是启用 glibc对Alpine容器的支持.

Another option for using a specific R version, which build is not available for native Alpine, is enabling glibc support on the Alpine container.

通常，Alpine建立在 musl libc 上，后者是专门的

Normally, Alpine builds on musl libc, which is a specialized libc implementation that is generally not compatible to glibc, which is the de-facto standard libc used by most other Linux distributions. With glibc installed, you should be able to run any general-purpose R Linux build on the Alpine container.

以下Dockerfile部分将启用glibc支持，从而为Alpine容器大小增加大约10MB:

The following Dockerfile portion would enable glibc support, adding some 10MB to the Alpine container size:

# Based on: https://github.com/anapsix/docker-alpine-java
FROM alpine:3.7

ENV GLIBC_REPO=https://github.com/sgerrand/alpine-pkg-glibc
ENV GLIBC_VERSION=2.28-r0

RUN set -ex && \
    apk --update add libstdc++ curl ca-certificates && \
    for pkg in glibc-${GLIBC_VERSION} glibc-bin-${GLIBC_VERSION}; \
        do curl -sSL ${GLIBC_REPO}/releases/download/${GLIBC_VERSION}/${pkg}.apk -o /tmp/${pkg}.apk; done && \
    apk add --allow-untrusted /tmp/*.apk && \
    rm -v /tmp/*.apk && \
    /usr/glibc-compat/sbin/ldconfig /lib /usr/glibc-compat/lib
