K8S五：部署node节点

1、把kubeconfig复制到node节点上

[root@localhost ssl]# scp *kubeconfig [email protected]:/opt/kubernetes/cfg/
[root@localhost ssl]# scp *kubeconfig [email protected]:/opt/kubernetes/cfg/

2、移动到k8s目录

[root@localhost ~]# mv kubelet kube-proxy /opt/kubernetes/bin/

3、赋予执行权限

[root@localhost ~]# chmod +x /opt/kubernetes/bin/*

4、赋予脚本执行权限

[root@localhost ~]# chmod +x *.sh

5、启动前创建用户(master机器执行)

[root@localhost ~]# kubectl create clusterrolebinding kubelet-bootstrap --clusterrole=system:node-bootstrapper --user=kubelet-bootstrap
clusterrolebinding "kubelet-bootstrap" created

6、执行kubelet.sh 参数一:当前机器IP    参数二:DNS地址

[root@localhost ~]# ./kubelet.sh 192.168.1.22 10.10.10.2

7、执行proxy.sh 参数一:当前机器IP

[root@localhost ~]# ./proxy.sh 192.168.1.22

8、允许node请求master证书(在master上执行)

查看node请求信息
[root@localhost ~]# kubectl get csr
NAME                                                   AGE       REQUESTOR           CONDITION
node-csr-uVVOaLhhBzQmC8KabkTCjnuUutuMQzZxLhumoHQ5T6Q   26m       kubelet-bootstrap   Pending

允许访问
[root@localhost ~]# kubectl certificate approve node-csr-uVVOaLhhBzQmC8KabkTCjnuUutuMQzZxLhumoHQ5T6Q
certificatesigningrequest "node-csr-uVVOaLhhBzQmC8KabkTCjnuUutuMQzZxLhumoHQ5T6Q" approved

允许访问后的状态
[root@localhost ~]# kubectl get csr
NAME                                                   AGE       REQUESTOR           CONDITION
node-csr-uVVOaLhhBzQmC8KabkTCjnuUutuMQzZxLhumoHQ5T6Q   30m       kubelet-bootstrap   Approved,Issued

查看已经加入的节点信息
[root@localhost ~]# kubectl get node
NAME           STATUS    ROLES     AGE       VERSION
192.168.1.22   Ready     <none>    1m        v1.9.0
