##########################################
修改参数:
1、image修改为阿里云镜像registry.cn-hangzhou.aliyuncs.com/google_containers/nginx-ingress-controller:0.25.0
2、kind修改为DaemonSet,apiVersion修改为extensions/v1beta1
3、replicas: 1 #删除此行，DaemonSet不需要此参数
4、hostNetwork: true #添加该字段让docker使用物理机网络，在物理机暴露服务端口(80)，注意物理机80端口提前不能被占用
5、dnsPolicy: ClusterFirstWithHostNet #使用hostNetwork后容器会使用物理机网络包括DNS，会无法解析内部service，使用此参数让容器使用K8S的DNS
6、nginx-ingress: "true" #添加节点标签
7、tolerations: 添加对指定节点污点容忍度
# 创建ingress-ingress的service
[root@test-k8s-master01 ~]# cat svc-ingress-nginx.yaml
