Why do you need this?

I have configured the ingress of openfaas, and I want to use sub path url to access the gateway

apiVersion: networking.k8s.io/v1

  - host: example.com      
    http:                                  
      paths:                               
      - backend:                           
          service:                         
            name: gateway                  
            port:                          
              number: 8080                 
        path: /sub-path                     
        pathType: ImplementationSpecific   
status:                                    
  loadBalancer:                         
    ingress:                            
    - ip: xxx.xx.xxx.xx

Expected Behaviour

access the gateway by sub path url
like example/sub-path/ui/
or example.com/sub-path/function/hello-world

Current Behaviour

not working now

curl example.com/sub-path

Hi,

You've not actually answered this question

Why do you need this?

Instead you just wrote the technical solution you want without any context about why this is something you feel needs to be different to the openfaas design.

Answer this well, and we may be able to help you.

I hope to have a global Nginx gateway to distribute my HTTP requests to different OpenFaas clusters, but also hope that their domain name is same.
For example, request to example.com/server-group-a will be distributed to the OpenFaas cluster of group-a, while request to example.com/server-group-b are distributed to the OpenFaas cluster of group-b.
