系统 centos
uname -a
uname -r
cat /etc/redhat-release   #查看操作系统版本
ls -l /sys/class/misc/device-mapper/

yum包更新到最新

sudo yum update -y
安装需要的软件包、yum-util提供yum-config-manager功能  
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

设置yum源为阿里云

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

安装docker

sudo yum install docker-ce -y
docker -v 查看版本

配置docker镜像加速器

mkdir /etc/docker
vi /etc/docker/daemon.json
{
    "registry-mirrors": [
        "https://wa0xneb0.mirror.aliyuncs.com",
        "http://hub-mirror.c.163.com",
        "https://mirrors.tuna.tsinghua.edu.cn",
        "http://mirrors.sohu.com",
        "https://ustc-edu-cn.mirror.aliyuncs.com",
        "https://ccr.ccs.tencentyun.com",
        "https://docker.m.daocloud.io",
        "https://docker.awsl9527.cn"
    ]
}
sudo systemctl daemon-reload
sudo systemctl restart docker

注意：阿里云镜像 需要登录阿里云账号，获取对应的阿里云镜像加速器，每个账号不一样

启动docker和相关状态查询命令

systemctl start docker
systemctl stop docker
systemctl restart docker

systemctl enable docker
docker info

网卡转发

sysctl -a | grep -w net.ipv4.ip_forward 响应为1正常
否则，执行下面
cat <<EOF> /etc/sysctl.d/docker.conf
net.bridge.bridge-nf-call-ip6tables=1
net.bridge.bridge-nf-call-iptables=1
net.ipv4.ip_forward=1
EOF
sysctl -p /etc/sysctl.d/docker.conf
