k8s部署ingress-nginx报错拍错

　　不是ingress-Nginx不成功出现错误提示

kubectl describe pod nginx-ingress-controller-6ffc8fdf96-xtg6n -n ingress-Nginx

　　对应node的kubelet日志

systemctl status kube-proxy -l

　　报错如下

kuberuntime_container.go:490] preStop hook for container "nginx-ingress-controller" Failed: command '/wait-shutdown' exited with 137:

　　查看pod日志

# kubectl logs nginx-ingress-controller-6ffc8fdf96-xtg6n -n ingress-Nginx
-------------------------------------------------------------------------------
Nginx Ingress controller
  Release:       0.30.0
  Build:         git-7e65b90c4
  Repository:    https://github.com/kubernetes/ingress-Nginx
  Nginx version: Nginx/1.17.8

-------------------------------------------------------------------------------

W0430 09:48:42.198239       6 flags.go:260] SSL certificate chain completion is disabled (--enable-ssl-chain-completion=false)
W0430 09:48:42.198310       6 client_config.go:543] Neither --kubeconfig nor --master was specified.  Using the inClusterConfig.  This might not work.
I0430 09:48:42.198533       6 main.go:193] Creating API client for https://10.0.0.1:443

　　判断是10.0.0.443有问题

　　node上telnet失败

# telnet 10.0.0.1 443
Trying 10.0.0.1...

　　解决方法，修改kube-proxy配置把流量转发该成ipvs模式

cat /opt/kubernetes/cfg/kube-proxy

# cat /opt/kubernetes/cfg/kube-proxy
KUBE_PROXY_OPTS="--logtostderr=false \
--log-dir=/opt/kubernetes/logs/kube-proxy \
--v=4 \
--hostname-override=192.168.1.12 \
--cluster-cidr=10.0.0.0/24 \
--proxy-mode=ipvs \
--masquerade-all=true \
--kubeconfig=/opt/kubernetes/cfg/kube-proxy.kubeconfig"

　　增加的内容

　　重启kube-proxy

　　重新不是ingress-Nginx即可
