Let’s quick start.
Prepare docker-ce.repo
$ curl -L https://mirrors.ustc.edu.cn/docker-ce/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo
$ sed -i 's+https://download.docker.com+https://mirrors.ustc.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo
$ sed -i 's+$releasever+8+' /etc/yum.repos.d/docker-ce.repo
Install
$ yum install -y docker-ce
Enable system service
$ systemctl enable docker
$ systemctl start docker
Check service status
$ systemctl status docker
The result should show like below. Active status should be running.
[root@localhost ~]# systemctl status docker
