k8s ingress-nginx controller 0/1 ready 的问题解决

describe pod

 kubectl describe pod -n ingress-nginx   ingress-nginx-controller-544c75d465-6wpdm 

发现 报错提示10254 端口连不上,netstat -ntlpu|grep 10254 确实不存在

解决问题:
重启了kube-proxy 和kubelet

systemctl restart kube-proxy
systemctl restart kubelet

重新部署ingress-nginx controller

kubectl delete -f deploy.yaml
kubectl apply -f deploy.yaml

最后查看状态为1/1 ready，并且也找到了10254端口

[root@centos-7 ~]# netstat -ntlpu|grep 10254 
tcp6       0      0 :::10254                :::*                    LISTEN      56165/nginx-ingress
