报错内容如下:
[root@k8s-master1 ~]# kubectl get cs
Warning: v1 ComponentStatus is deprecated in v1.19+
NAME STATUS MESSAGE ERROR
scheduler Unhealthy Get "http://127.0.0.1:10251/healthz": dial tcp 127.0.0.1:10251: connect: connection refused
controller-manager Unhealthy Get "http://127.0.0.1:10252/healthz": dial tcp 127.0.0.1:10252: connect: connection refused
etcd-0 Healthy {"health":"true"}
原因:
kubectl get cs这个在未来将会被弃用,官方没有出具相应的去做修复,虽然得到的结果是Unhealthy,但实际不影响使用,如果看不顺眼也是有解决办法的。
解决办法:
操作很简单,就是在master节点上操作编辑kube-controller-manager.yaml与kube-scheduler.yaml配置文件, 找到 - --port=0 这一行添加 # 号注释,取消该监听,最后重启 kubelet 服务即可。
cat /etc/kubernetes/manifests/kube-controller-manager.yaml
cat /etc/kubernetes/manifests/kube-scheduler.yaml
systemctl restart kubelet.service
[root@k8s-master1 ~]# kubectl get cs
Warning: v1 ComponentStatus is deprecated in v1.19+
NAME STATUS MESSAGE ERROR
scheduler Healthy ok
controller-manager Healthy ok
etcd-0 Healthy {"health":"true"}
