         yum-config-manager --disable docker-ce-nightly
         yum install docker-ce docker-ce-cli containerd.io

配置鏡像加速，選擇阿里雲的源

#本身註冊一個阿里雲帳號，而後選擇ECS中的鏡像加速服務，就能夠出現一個加速地址，將加速地址配到json文件中

#也就是如下步驟

mkdir /etc/docker -p
    vim /etc/docker/daemon.json
    {
    "registry-mirrors": ["https://g80gj7jy.mirror.aliyuncs.com"]
    }
    systemctl daemon-reload
    systemctl restart docker

檢測docker進程測試

ps -ef|grep docker
        docker run hello-world
