一、kubernetes升级k8s-master02节点组件

### --- 查看k8s-master02相关组件版本
~~~     查看kube-apiserver kube-controller-manager kube-scheduler kube-proxy组件的版本

[root@k8s-master02 ~]# /usr/local/bin/kube-apiserver --version
Kubernetes v1.17.0
[root@k8s-master02 ~]# /usr/local/bin/kube-controller-manager --version
Kubernetes v1.17.0
[root@k8s-master02 ~]# /usr/local/bin/kube-scheduler --version
Kubernetes v1.17.0
[root@k8s-master02 ~]# /usr/local/bin/kube-proxy --version
Kubernetes v1.17.0

二、备份k8s-master02相关组件历史版本配置

### --- 备份kube-apiserver kube-controller-manager kube-scheduler kube-proxy服务文件

[root@k8s-master02 ~]# which kube-apiserver kube-controller-manager kube-scheduler kube-proxy
/usr/local/bin/kube-apiserver
/usr/local/bin/kube-controller-manager
/usr/local/bin/kube-scheduler
/usr/local/bin/kube-proxy
[root@k8s-master02 ~]# mkdir /usr/local/bin/bak/
[root@k8s-master02 ~]# cp /usr/local/bin/kube-apiserver /usr/local/bin/bak/
[root@k8s-master02 ~]# cp /usr/local/bin/kube-controller-manager /usr/local/bin/bak/
[root@k8s-master02 ~]# cp /usr/local/bin/kube-scheduler /usr/local/bin/bak/
[root@k8s-master02 ~]# cp /usr/local/bin/kube-proxy /usr/local/bin/bak/

三、停止k8s-master02相关组件服务

### --- 停止相关组件的服务 

[root@k8s-master02 ~]# systemctl stop kube-apiserver kube-controller-manager kube-scheduler kube-proxy

四、升级k8s-master02相关组件

### --- 升级相关组件服务

[root@k8s-master01 ~]# scp upgrade/master/kubernetes/server/bin/kube-apiserver k8s-master02:/usr/local/bin/
kube-apiserver                                                                                                                                    100%  110MB   3.9MB/s   00:27    
You have new mail in /var/spool/mail/root
[root@k8s-master01 ~]# scp upgrade/master/kubernetes/server/bin/kube-controller-manager k8s-master02:/usr/local/bin/
kube-controller-manager                                                                                                                           100%  102MB   3.8MB/s   00:26    
[root@k8s-master01 ~]# scp upgrade/master/kubernetes/server/bin/kube-scheduler k8s-master02:/usr/local/bin/
kube-scheduler                                                                                                                                    100%   40MB   4.2MB/s   00:09    
[root@k8s-master01 ~]# scp upgrade/master/kubernetes/server/bin/kube-proxy k8s-master02:/usr/local/bin/
kube-proxy  

五、启动k8s-master02相关组件服务

### --- 启动相关组件服务 

[root@k8s-master02 ~]# systemctl daemon-reload
[root@k8s-master02 ~]# systemctl restart kube-apiserver kube-controller-manager kube-scheduler kube-proxy

六、查看k8s-master02相关组件版本

### --- 查看相关组件版本

[root@k8s-master02 ~]# /usr/local/bin/kube-apiserver --version
Kubernetes v1.19.5
