原因： 最新版本的docker需要 1.2.2-3以上的containerd.io，可以选择安装低版本的docker,也可以升级 containerd.io，
- 查询可用的docker
yum list docker-ce --showduplicates | sort -r
# 选择安装
sudo yum install <FULLY-QUALIFIED-PACKAGE-NAME>
- 升级containerd.io
wget https://download.docker.com/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm
yum -y install containerd.io-1.2.6-3.3.el7.x86_64.rpm
#安装最新的docker
yum install docker-ce
docker命令
#启动
sudo systemctl start docker
#运行镜像hello-world
sudo docker run hello-world
卸载docker
#卸载
sudo yum remove docker-ce
# 删除docker相关容器镜像
sudo rm -rf /var/lib/docker
