安裝步驟：
3.問題分析
centos8默認使用podman代替docker，所以需要containerd.io绅这，那我們就安裝一下就好了
4.解決方法
安裝containerd.io即可
yum install https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io-1.2.6-3.3.fc30.x86_64.rpm
然后繼續(xù)安裝Docker
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum install -y docker-ce
systemctl start docker
systemctl enable docker
