Docker-alpine: Any plan to build docker-alpine based on alpine 3.8?

[subjectxbj]

Recently alpine 3.8 came out. Is there any plan to build a new docker image for alpine 3.8.

I found I can't build grpc on alpine 3.7. the version of "binutils" is still 2.28. So the "ld" tool does not support certain options like "-Wl", while 2.30 can support that.

So it will be great if I can get a 3.8 alpine docker.

Alpine 3.8 is not released yet: https://alpinelinux.org

用 3.7 版本的包，真的太旧啦，edge 版本不敢用，等 3.8 维稳在升级呗。

3.8 is released now.

@subjectxbj you can use alpine edge for that instead of alpine latest, or add the edge repos in your dockerfile. In mountainr dockerfiles, I use:

RUN echo '@edge http://nl.alpinelinux.org/alpine/edge/community' >> /etc/apk/repositories \ 
    && echo '@edge http://nl.alpinelinux.org/alpine/edge/main' >> etc/apk/repositories \
    && apk add --upgrade --no-cache apk-tools@edge

RUN ["apk", "add", "binutils@edge"]

You should check your settings, bcs according to the package database, binutils is version 2.30 in alpine 3.7:

While waiting for the official alpine:3.8 I´d recommend something like:
Dockerfile RUN echo 'http://dl-cdn.alpinelinux.org/alpine/v3.8/main' > /etc/apk/repositories \ && echo 'http://dl-cdn.alpinelinux.org/alpine/v3.8/community' >> /etc/apk/repositories \ && apk upgrade -U -a
