docker 安装

1、安装、

wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.ustc.edu.cn/docker-ce/linux/centos/docker-ce.repo

sed -i 's#download.docker.com#mirrors.ustc.edu.cn/docker-ce#g' /etc/yum.repos.d/docker-ce.repo

yum install docker-ce -y

systemctl enable docker.service


systemctl restart docker.service

 

2、配置docker镜像加速

vi /etc/docker/daemon.json
{
  "registry-mirrors": ["https://registry.docker-cn.com"]
}    

 

 

3、配置docker远程端口监听

vim /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -H tcp://10.0.0.100:2375    ## 阿里云服务器 将10.0.0.100 改成 内网地址 或者 0.0.0.0 即可
systemctl daemon-reload
systemctl enable docker.service 
systemctl restart docker.service


测试：
选择另一台安装好docker的阿里云服务器

[root@iZbp16cdvzk4rhl0vn1gedZ ~]# docker -H 172.16.77.9 info    ## 172.16.77.9 为内网地址
