编写了⼀个Dockerfile，主要⽬的是构建⼀个镜像，镜像默认安装了openjdk-1.8-jre，还有另外⼀些包（这些包⾥⾯有dev版本的，也有release版本的），Dockerfile的内容⼤致如下：
FROM ubuntu:16.04
RUN echo"deb mirrors.aliyun/ubuntu/ xenial main restricted universe multiverse" > /etc/apt/sources.list \
&& echo"deb mirrors.aliyun/ubuntu/ xenial-security main restricted universe multiverse" >> /etc/apt/sources.list \
&& echo"deb mirrors.aliyun/ubuntu/ xenial-updates main restricted universe multiverse" >> /etc/apt/sources.list \
&& echo"deb mirrors.aliyun/ubuntu/ xenial-backports main restricted universe multiverse" >> /etc/apt/sources.list \
&& echo"deb mirrors.aliyun/ubuntu/ xenial-proposed main restricted universe multiverse" >> /etc/apt/sources.list \董贞 刀剑如梦
&& apt-get update
本兮死亡原因#安装openjdk-8-jre
RUN apt-get install -y openjdk-8-jre --fix-missing
#安装其他使⽤的包
RUN apt-get install -y tar ubuntu-make autoconf automake build-essential libass-dev libfreetype6-dev \
libsdl1.2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev \
libxcb-xfixes0-dev pkg-config texinfo zlib1g-dev libx264-dev libfdk-aac-dev yasm --fix-missing
这段Dockerfile build没有通过，在3台机器（分别对应不同的⽹络环境）上测试过，只有其中⼀个环境是能build成功，报错的两个环境都是以下错误（有差异的原因现在也没搞清楚，搞了两三个星期了，很晕）

这个问题困扰了好长⼀段时间，之后尝试了⼀下只使⽤main的源，其他的删除掉，jre能安装成功，但是后⾯的那些包⼜不到。所以最后只能使⽤以下的work around⽅案把镜像做成了：
FROM ubuntu:16.04
#openjdk-8-jre使⽤了updates源之后报hash sum mismatch的错误，
#只能使⽤main才能安装成功，这个问题没有到根本原因，暂时使⽤此解决⽅式
