CentOS kubernetes单机部署

CentOS kubernetes单机部署

1、关闭防火墙

systemctl disable firewalld systemctl stop firewalld 

2、安装etcd和kubernetes软件(会自动安装docker)

yum install -y etcd kubernetes 

** 需要修改两处配置：**

• Docker 配置文件/etc/sysconfig/docker , OPTIONS='--seliunx-enabled=false --insecure-registry gcr.io'
• kubernetes apiservce 配置文件/etc/kubernetes/apiserver,把--admission_control参数中的ServiceAccount删除。

3、按下面的顺序启动所有服务：

systemctl start etcd systemctl start docker systemctl start kube-apiserver systemctl start kube-controller-manager systemctl start kube-scheduler systemctl start kubelet systemctl start kube-proxy 

** 安装完成:**
ps -ef|grep kube查看一下。

停止：

systemctl stop kube-proxy systemctl stop kubelet systemctl stop kube-scheduler systemctl stop kube-controller-manager systemctl stop kube-apiserver systemctl stop docker systemctl stop etcd 

可以开始使用了！
