centos8 安装docker

第一步：关闭防火墙和selinux

#关闭防火墙

systemctl stop firewalld

systemctl disable firewalld

# 关闭 SeLinux

setenforce 0

sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

 

 第二步：进入阿里云镜像找到最新版本的镜像进行安装

https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/edge/Packages/

 

yum install -y https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.13-3.2.el7.x86_64.rpm

 

yum install -y https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/edge/Packages/docker-ce-19.03.9-3.el7.x86_64.rpm

 

yum install -y https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/edge/Packages/docker-ce-cli-19.03.9-3.el7.x86_64.rpm

 

第三步：镜像加速

cat > /etc/docker/daemon.json <<EOF

{

    "registry-mirrors":[

        "https://kfwkfulq.mirror.aliyuncs.com",

        "https://2lqq34jg.mirror.aliyuncs.com",

        "https://pee6w651.mirror.aliyuncs.com",

        "http://hub-mirror.c.163.com",

        "https://docker.mirrors.ustc.edu.cn",

        "https://registry.docker-cn.com"

    ]

}

EOF

第四步：固定IP

docker network create --subnet=172.18.0.0/16 mynetwork

docker run -itd --name test --net mynetwork --ip 172.18.0.2 centos:7 /bin/bash
