docker中apt-get update出现问题

Question

使用官方镜像php:5.6-fpm,修改/etc/apt/sources.list文件的源后apt-get update提示如下：

使用的源为：

deb http://mirrors.aliyun.com/debian/ stretch main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch main non-free contrib
deb http://mirrors.aliyun.com/debian-security stretch/updates main
deb-src http://mirrors.aliyun.com/debian-security stretch/updates main
deb http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib

补充下面的错误信息：

Debian stretch (Debian 9) 已经撤掉了这些Component，因为已经是oldstable了，所以并没有这么多Component可供使用，你直接照抄肯定出错。

在docker中不要照抄那些仓库，很多docker镜像用的并不一定是最新版本的Debian/Ubuntu，不能保证这么多的Component可以使用，因此你要使用国内镜像的话应该替换掉/etc/apt/sources.list中官方仓库地址即可，参考命令:

sed -i 's/deb.debian.org/mirrors.aliyun.com/;s/security.debian.org/mirrors.aliyun.com/' /etc/apt/sources.list

重新运行一个新的容器执行上面的命令替换镜像仓库即可。
