k8s故障：故障现象 ComponentStatus is deprecated in v1.19+查看状态存在不健康组件

1、故障现象 查看状态存在不健康组件：

[root@beian k8s]# kubectl get cs

Warning: v1 ComponentStatus is deprecated in v1.19+

NAME                STATUS      MESSAGE                                                                                      ERROR

controller-manager  Unhealthy  Get "http://127.0.0.1:10252/healthz": dial tcp 127.0.0.1:10252: connect: connection refused 

scheduler            Unhealthy  Get "http://127.0.0.1:10251/healthz": dial tcp 127.0.0.1:10251: connect: connection refused 

etcd-0              Healthy    {"health":"true"}     

2，解决办法

[root@beian k8s]# cd /etc/kubernetes/manifests/

[root@beian manifests]# ls

etcd.yaml  kube-apiserver.yaml  kube-controller-manager.yaml  kube-scheduler.yaml

[root@beian manifests]# vim kube-controller-manager.yaml

[root@beian manifests]# vim kube-scheduler.yaml

``以上两个文件注释掉

- --port=0

``

3、验证

[root@beian manifests]# systemctl restart kubelet.service

[root@beian manifests]# kubectl get cs
