安装docker

出现问题

解决办法https://blog.csdn.net/VOlsenBerg/article/details/70140211

发现链接超时，然后就https://blog.csdn.net/mingmingysm/article/details/81084313

发现还是超时https://linux.cn/article-9223-1.html

那么就设置访问某个网站 我们通过代理来访问 再试试

还是不行，额。还是https://blog.csdn.net/qq_33951308/article/details/81140922

安装完以后 我们在运行一个命令

这样我们就不能每次都带上sudo才能运行了 方便
