[root@Computer02 script]# vim ingress-kubernetes-dashboard.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: dashboard
  annotations:
    kubernetes.io/ingress.class: "nginx"               # 被nginx所解析的ingress资源
    ingress.kubernetes.io/ssl-passthrough: "true"      # 此处不是做http代理而是做TCP代理，由于dashboard是ssl会话，所以此处不做ssl卸载直接转给后端dashboard
    nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"   
    nginx.ingress.kubernetes.io/rewrite-target: /$2    # 此处对/dashboard/做rewrite，$2表示path后面的(.*)，表示将/dashboard(/|$)(.*)转发到后端后都重写为以/(.*)为起始的，把/dashboard/前缀去除。
  namespace: kubernetes-dashboard
spec:
  rules:
  - http:
      paths:
      - path: /dashboard(/|$)(.*)
        backend:
          serviceName: kubernetes-dashboard
          servicePort: 443
