Docker 笔记

下载yum文件
wget https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo

vim docker-ce.repo
把里面的网址替换为国内docker安装的网址 (%s@s_content@d_content@)
https://mirrors.tuna.tsinghua.edu.cn/docker-ce

安装:
yum install docker-ce

做仓库加速
mkdir /etc/docker && vim daemon.json
{
"registry-mirrors": ["https://registry.docker-cn.com"]
}

systemctl start docker.service
