这篇文章介绍了如何快速部署一套Kubernetes集群,下面就快速开始吧！
准备工作
//关闭防火墙systemctl stop firewalld.servicesystemctl disable firewalld.service//关闭selinux,修改/etc/selinux/configSELINUX=disabled机器部署规划
| 主机 | IP | 部署组件 |
|---|---|---|
| master主节点 | 192.168.199.206 | etcd、kube-apiserver、kube-controller-manager、kube-scheduler |
| node1子节点 | 192.168.199.159 | kubelet、kube-proxy、docker |
| node2子节点 | 192.168.199.175 | kubelete、kube-proxy、docker |
k8s组件采用yum安装的方式，快速安装。
