快速部署和測試ingress-nginx:1.9.6

下載deploy文件
https://github.com/kubernetes/ingress-nginx/blob/controller-v1.9.6/deploy/static/provider/cloud/deploy.yaml
修改deploy文件:
有如下幾處可按需修改：

DaemonSet：修改 Deployment 為 DaemonSet，移除 strategy 字段；
hostNetwork：使用宿主機的網絡；
nodeSelector：添加標簽選擇器（可選）；
將名為 ingress-nginx-controller 的 Service 類型改為 ClusterIP（要刪除 externalTrafficPolicy 字段）；

apiVersion: apps/v1
kind: DaemonSet  # 這里把 Deployment 改成 DaemonSet

  labels:
    ...
