kubeasz工具增删master与node

添加mater节点

当前节点

[root@master1 kubeasz]# ./ezctl add-master k8s-cluster1 192.168.181.112
                                           集群名称       新增的masterIP
增加node节点
[root@master1 kubeasz]# ./ezctl add-node k8s-cluster1 192.168.181.142
删除node节点
[root@master1 kubeasz]# ./ezctl del-node k8s-cluster1 192.168.181.142

查看节点信息

 

 

 手动删除matser与node节点

先驱逐，再删除node

手动强制驱逐node节点
[root@master1 kubeasz]#  kubectl drain 192.168.181.142 --ignore-daemonsets --delete-emptydir-data
                                                            忽略数据             日志、临时文件删除
[root@master1 kubeasz]#  kubectl delete node 192.168.181.142

 

 

集群升级

haproxy配置文件，注释需要升级的节点配置

[root@ha1 ~]# systemctl reload haproxy.service

暂停master3的服务

[root@master3 ~]#systemctl stop kube-apiserver.service kube-controller-manager kubelet kube-proxy.service kube-scheduler.service

每个node节点都要执行

[root@node2 ~]# vim /etc/kube-lb/conf/kube-lb.conf

[root@node2 ~]# systemctl restart kubee--lb

master1上的新版本的二进制包拷贝到master3，替换master3  /usr/bin里的文件

[root@master1 bin]# scp -r kube-apiserver kube-controller-manager kubectl kubelet kube-scheduler 192.168.181.112:/usr/bin/

拷贝完后启动master3的服务

[root@master3 ~]# systemctl start kube-apiserver.service kube-controller-manager kubelet kube-proxy.service kube-scheduler.service

master3升级成功

 

 

 

master1和master2同理，暂停服务

[root@master1 ~]##systemctl stop kube-apiserver.service kube-controller-manager kubelet kube-proxy.service kube-scheduler.service

  [root@master2 ~]# systemctl stop kube-apiserver.service kube-controller-manager kubelet kube-proxy.service kube-scheduler.service

haroxy配置文件注释

[root@ha1 ~]# systemctl reload haproxy.service

 

 

 

 所有node节点执行

[root@node2 ~]# vim /etc/kube-lb/conf/kube-lb.conf

[root@node2 ~]# systemctl restart kubee--lb

拷贝新版本的二进制文件到master1和master的/usr/bin

 

 

 启动服务

[root@master1 ~]# systemctl start kube-apiserver.service kube-controller-manager kubelet kube-proxy.service kube-scheduler.service
[root@master2 ~]# systemctl start kube-apiserver.service kube-controller-manager kubelet kube-proxy.service kube-scheduler.service

所有master节点由v1.22.2版本升级到v1.22.5

 

 

 负载均衡器配置文件去掉之前的注释

[root@ha1 ~]# systemctl reload haproxy.service

至此master节点升级完成
