Routing a LoadBalancer Ingress to Multiple Services

Ingresses can route to multiple backend Services based on different matching policies. The spec field in the YAML file is set as below. You can access www.example.com/foo, www.example.com/bar, and foo.example.com/ to route to three different backend Services.

The URL registered in an ingress forwarding policy must be the same as the URL used to access the backend Service. Otherwise, a 404 error will be returned.

For example, the default access URL of the Nginx application is /usr/share/nginx/html. When adding /test to the ingress forwarding policy, ensure the access URL of your Nginx application contains /usr/share/nginx/html/test. Otherwise, error 404 will be returned.
