在线安装 docker

1
yum install -y yum-utils
1
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
1
yum install https://mirrors.aliyun.com/docker-ce/linux/centos/8/x86_64/stable/Packages/containerd.io-1.6.8-3.1.el8.x86_64.rpm

更新 container.io 包, 否则可能会报 package docker-ce-3:19.03.13-3.el7.x86_64 requires containerd.io >= 1.2.2-3, ...的错，可在 https://mirrors.aliyun.com/docker-ce/linux/centos/8/x86_64/stable/Packages/ 下找最新版安装

1
yum install docker-ce -y

验证

1
systemctl enable docker.service
