How to deny path in k8S ingress - kubernetes

Question

I would like to block /public/configs in my k8s ingress.
My current settings doesnt work.
- host: example.com
http:
paths:
- path: /*
pathType: ImplementationSpecific
backend:
service:
name: service-myapp
port:
number: 80
- path: /public/configs
pathType: ImplementationSpecific
backend:
service:
name: service-myapp
port:
number: 88 // fake port
Is there any better (easy) way?

Answer 1

1- Create a dummy service and send it to that:
- path: /public/configs
pathType: ImplementationSpecific
backend:
service:
name: dummy-service
port:
number: 80
2- use server-snippets as bellow to return 403 or any error you want:
a) for k8s nginx ingress:
annotations:
nginx.ingress.kubernetes.io/server-snippet: |
location ~* "^/public/configs" {
deny all;
return 403;
}
b) for nginx ingress:
annotations:
nginx.org/server-snippet: |
location ~* "^/public/configs" {
deny all;
return 403;
}
