nginx-ingress-controller:0.25.0有问题，所以这里采用nginx-ingress-controller:0.30.0
[root@k8s-master ~]# wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.30.0/deploy/static/mandatory.yaml
[root@k8s-master ~]# cat mandatory.yaml | grep image image: quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.30.0
所有节点下载quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.30.0 [root@k8s-master ~]# docker pull quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.30.0
[root@k8s-master ~]# kubectl apply -f mandatory.yaml

为了测试效果，我在Windows主机上的C:\Windows\System32\drivers\etc\hosts建立以下DNS记录
10.10.21.8 www1.normantest.com
在浏览器访问www1.normantest.com:31355，访问页面出错
[root@k8s-master ~]# ipvsadm -Ln（可以看到当访问NodePort的31355端口时，其实访问的是nginx-ingress-controller 10.244.1.198 的80）
进入容器nginx-ingress-controller 排错：
[root@k8s-master ~]# kubectl exec nginx-ingress-controller-7fcf8df75d-v42m9 -it -n ingress-nginx /bin/bash
bash-5.0$ ls
fastcgi.conf geoip mime.types nginx.conf scgi_params uwsgi_params.default
fastcgi.conf.default koi-utf mime.types.default nginx.conf.default scgi_params.default win-utf
fastcgi_params koi-win modsecurity opentracing.json template
fastcgi_params.default lua modules owasp-modsecurity-crs uwsgi_params
bash-5.0$ vi nginx.conf (发现上面部署的ingress没有注入到nginx-ingress-controller的nginx配置中，修改后正确配置如下)
最后成功访问
