参考docker官网文档：https://docs.docker.com/engine/install/centos/
卸载之前安装的docker

yum remove docker \

docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine

步骤二：安装工具包

 sudo yum install -y yum-utils

设置docker安装地址

 sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

yum install docker-ce docker-ce-cli containerd.io

启动docker

systemctl start docker

查看docker版本

docker -v

列出本地镜像

 docker images

设置docker开机自启

}
EOF
{
