# cat ingress.yaml 
apiVersion: networking.k8s.io/v1beta1 # networking.k8s.io/v1 / extensions/v1beta1 
kind: Ingress

  annotations:
    kubernetes.io/ingress.class: "nginx"
  name: example
spec:
  rules: # 一个Ingress可以配置多个rules
  - host: foo.bar.com # 域名配置，可以不写，匹配*， *.bar.com
    http:
      paths: # 相当于nginx的location配合，同一个host可以配置多个path / /abc
      - backend:
          serviceName: nginx-svc 
          servicePort: 80
        path: /

创建一个多域名ingress

cat ingress-mulDomain.yaml

        path: /
  - host: foo2.bar.com # 域名配置，可以不写，匹配*， *.bar.com
    http:
      paths: # 相当于nginx的location配合，同一个host可以配置多个path / /abc
      - backend:
          serviceName: nginx-svc-external
          servicePort: 80
        path: /
