查看當前源的可用版本

yum list docker-ce --showduplicates|grep "^doc"|sort -r
  
yum list docker-ce-cli --showduplicates|grep "^doc"|sort -r

指定安裝 client 跟 server 一樣的版本 ( 不指定版本會自動安裝最新版 )

yum install docker-ce-20.10.2-3.el7 docker-ce-cli-20.10.2-3.el7 containerd.io

查看版本

docker version

設置開機啟動

systemctl enable docker

安裝 docker-compose

yum list docker-compose-plugin --showduplicates|grep "^doc"|sort -r
    
yum install docker-compose-plugin-2.6.0-3.el7
    
ln -s /usr/libexec/docker/cli-plugins/docker-compose /usr/bin/docker-compose
