Ubuntu 18.04 apt 改为阿里云源
目录
仅作记录，Ubuntu 不管是系统还是docker镜像都比较常用。但是 ubuntu docker 没有 vim，更新国内源不方便。很多时候都要用 volume 把源映射进去，非常麻烦。
先检查Ubuntu阿里云源有没有炸
❐ 点我看一看阿里云源是否正常访问，如果不能访问请留言通知我阿里云源 sources.list
deb https://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
有 vim
直接 vim 复制粘贴即可
有 wget 或者 curl
本站提供的 sources.list 文件下载，可用 wget 下载。
❐ 稍微看看本站的 sources.list也可以自己部署到 github 或者 gitee gitlab，一类的托管网站，然后自己下载。
wget https://luo3.org.cn/files/ubuntu1804-aliyun.sources.list
我的系统什么都没有，只能 echo
可能我不是很会 nano，不过 docker 镜像为了精简，有时候切掉了紧急运维工具。
可以用 echo 逐行写入
echo 'deb https://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse' >> /etc/apt/sources.list
echo 'deb https://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse' >> /etc/apt/sources.list
echo 'deb https://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse' >> /etc/apt/sources.list
echo 'deb https://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse' >> /etc/apt/sources.list
echo 'deb https://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse' >> /etc/apt/sources.list
Dockerfile 版
可以用 Dockerfile 构建出集成阿里云源的镜像，就不用每次创建容器都要改源了。
用法:
docker build -t ubuntu:18.04-aliyun -f <Dockerfile文件位置> /tmp
FROM ubuntu:18.04
RUN mv /etc/apt/sources.list /etc/apt/sources.list.old \
&& echo 'deb https://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse' >> /etc/apt/sources.list \
&& echo 'deb https://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse' >> /etc/apt/sources.list \
&& echo 'deb https://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse' >> /etc/apt/sources.list \
&& echo 'deb https://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse' >> /etc/apt/sources.list \
&& echo 'deb https://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse' >> /etc/apt/sources.list
