#更新apt-get源 使用163的源
RUN mv /etc/apt/sources.list /etc/apt/sources.list.bak && \
    echo "deb http://mirrors.163.com/debian/ jessie main non-free contrib" >/etc/apt/sources.list && \
    echo "deb http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list && \
    echo "deb-src http://mirrors.163.com/debian/ jessie main non-free contrib" >>/etc/apt/sources.list && \
    echo "deb-src http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list

玩docker完全可以用国内某站镜像啊国内某站镜像

要不咱用一个proxychain代理一个科学上网到1080端口,然后去请求官方源,速度也不慢。我是这么做的。

公司的话, 内部或测试机子做个私有的镜像存放服务器, 免得每次提交更新镜像都慢的蛋疼

官方的镜像大多是基于 debian:jessie 的,如果这个基础镜像经常拉取失败的话有个小窍门:

直接从国内的镜像站拉取镜像,如 daocloud ,这时拉取的镜像的名称大致是这样的: daocloud.io/library/debian:jessie,然后执行 docker tag daocloud.io/library/debian:jessie debian:jessie 就可以完成类似重命名镜像的操作(其实是给同一个镜像打了两个标签)。因为执行构建的时候会首先查找本地是否有对应名称的镜像,所以就不会从网上下载 debian 的基础镜像了

(配置 Docker 加速器) 不配置基本下载不了,墙的厉害

进入 https://dashboard.daocloud.io/ 先注册一个账号,没收费, 然后登陆后 进入个人中心,里面有 加速器,点击进入就好,然后就自己看了。里面有 Linux mac windows 的用法,

参考文章 : https://segmentfault.com/a/11…

RUN sed -i [email protected]/archive.ubuntu.com/@/mirrors.aliyun.com/@g /etc/apt/sources.list
RUN apt-get clean
RUN apt-get update
