修改国内镜像源：

swr.cn-north-4.myhuaweicloud.com/ddn-k8s/registry.k8s.io/ingress-nginx/controller:v1.10.1
swr.cn-north-4.myhuaweicloud.com/ddn-k8s/registry.k8s.io/ingress-nginx/kube-webhook-certgen:v1.4.1

registry.k8s.io/ingress-nginx/kube-webhook-certgen:v1.4.1

—增加配置

422     spec:
423       hostNetwork: true   ###与宿主机共享网络
424       containers:
425       - args:
426         - /nginx-ingress-controller
427         - --publish-service=$(POD_NAMESPACE)/ingress-nginx-controller
428         - --election-id=ingress-nginx-leader
429         - --controller-class=k8s.io/ingress-nginx
430         - --ingress-class=nginx
431         - --configmap=$(POD_NAMESPACE)/ingress-nginx-controller
432         - --validating-webhook=:8443
433         - --validating-webhook-certificate=/usr/local/certificates/cert
434         - --validating-webhook-key=/usr/local/certificates/key
435         - --enable-metrics=false

#支持master节点部署
我这里要支持在master节点部署，所以要加一个配置：

  tolerations:       #设置能在master上部署
  - key: node-role.kubernetes.io/master
    operator: Exists

修改后的结果如下：

spec:
      hostNetwork: true  #与宿主机共享网络
      tolerations:       #设置能在master上部署
      - key: node-role.kubernetes.io/master
        operator: Exists
      containers:
      - args:
        - /nginx-ingress-controller
        - --publish-service=$(POD_NAMESPACE)/ingress-nginx-controller
        - --election-id=ingress-nginx-leader
        - --controller-class=k8s.io/ingress-nginx
        - --ingress-class=nginx
        - --configmap=$(POD_NAMESPACE)/ingress-nginx-controller
        - --validating-webhook=:8443
        - --validating-webhook-certificate=/usr/local/certificates/cert
        - --validating-webhook-key=/usr/local/certificates/key

            name: tomcat-service
            port:
              number: 8080

部署 tomcat ingress yaml

kubectl  apply  -f  tomcat-ingress.yaml

查看 ingress 对应节点的端口

 kubectl get svc -n ingress-nginx

添加 hosts
在 hosts 文件最后追加 ingress 节点的 IP 地址

192.168.2.67 tomcat.cctbb.com

然后在浏览器中访问 tomcat.cctbb.com:30497。
