搭建kubernetes集群

创建kubernetes集群

master192.168.2.24

（开启服务：kube-apiserver,kube-controller-manage,kube-scheduler,etcd）

Node 192.168.2.22(物理机)

Node 192.168.2.51（虚拟机）

 ( 开启服务：kube-proxy,kubelet,flanneld,docker)

1.在node节点上配置Flanneld的网络（docker已经安装好）

 首先在master安装并开启etcd服务

 安装etcd：yum install etcd

 开启etcd服务:systemctl enable etcd

              Systemctl start  etcd

配置etcd   /etc/etcd/etcd.conf

地址可以写 127.0.0.1:4001或 主机ip：4001

设置flanneld网桥的网段

etcdctl -C http://192.168.2.24:4001 set /coreos.com/network/config '{ "Network": "10.0.0.0/16" }'

配置node节点上flanneld  /etc/sysconfig/flanneld

删除之前的docker网桥

Ifconfig docker0 down

Brctl delbr docker0

开启flanneld服务

systemctl enable flanneld

syetmctl start flanneld

重启docker

Systemctl restart docker

查看网桥ip

测试网络连通在24上ping 10.0.33.1

注:在flanneld启动的时候会在node节点上创建docker网桥并分配ip，以此保证PodIp唯一

并且自动添加路由规则

1.开启master节点的kube-apiserver,kube-controller-manager

Kube-scheduler服务

配置master

配置apiserver

开启各服务

Systemctl enable kube-apiserver

Systemctl enabel kube-controller-manager

Systemctl enable kube-scheduler

 

Systemctl start kube-apiserver

Systemctl start kube-controller-manager

Systemctl start kube-scheduler

1.开启node节点的kube-proxy，kubelet服务

配置kubelet

开启各服务

 

Systemctl enable kubelet

Systemctl enable kube-proxy

 

Systemctl start kubelet

Systemctl start kube-proxy

1.在master节点上查看
