1、环境准备
操作系统Centos7.7
2、安装所需软件
sudo yum update sudo yum install curl telnet git docker
3、修改Docker配置，支持私有的registry
sudo vi /etc/docker/daemon.json
#内容如下
{
"insecure-registries" : [ "172.30.0.0/16"]
}
4、启动Docker
sudo systemctl start docker sudo systemctl status docker sudo systemctl enable docker
5、下载最新版本的openshift origin
https://github.com/openshift/origin/releases/ wget https://github.com/openshift/origin/releases/download/v3.11.0/openshift-origin-server-v3.11.0-0cbc58b-linux-64bit.tar.gz tar -xf openshift-origin-server-v3.11.0-0cbc58b-linux-64bit.tar.gz
6、开启cluster
