其实DigitalOcean这边的系统还是干净的，没有安装多余的部件，直接跑下面的命令就行

sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum install -y docker-ce docker-ce-cli containerd.io
sudo systemctl start docker
sudo docker run hello-world

OK，hello-world出来，docker安装完成，登录一下

[root@master ~]# docker login
