centos 安装docker

centos8默认使用podman代替docker，所以需要containerd.io.

安装containerd.io

yum install https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io-1.2.6-3.3.fc30.x86_64.rpm

安装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

//启动docker

systemctl start docker

//添加开机启动

systemctl enable docker

解决办法，执行下面的命令:

 

[root@localhost ~]# yum erase podman buildah

 

再执行：yum install -y docker.ce 就可以正常安装了
