nginx-ingress add custom header for a specific path - nginx

Question

I have the following nginx-ingress in a kubernetes environment
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/configuration-snippet: |
more_set_headers "cache-control: no-store";
more_set_headers "MyCustomHeader: Value";
spec:
rules:
- http:
paths:
- backend:
serviceName: svc1
servicePort: 80
# Want to add the custom headers in this path only
path: /
- backend:
serviceName: svc2
servicePort: 80
path: /cacheable-path
I have a couple of headers that I want to set Cache-Control and MyCustomHeader. But I want these headers to be set only for the root path / and not for other routes (like /cacheable-path).
How to achieve this ? Adding the annotation causes the header to be appended to all the responses. I want the headers to be added to a specific path only.

It is not possible to add headers for a specific path in a single Ingress resource. You will have to create two Ingress resources.
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/configuration-snippet: |
more_set_headers "cache-control: no-store";
more_set_headers "MyCustomHeader: Value";
spec:
rules:
- http:
paths:
- backend:
serviceName: svc1
servicePort: 80
path: /
Without header
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: nginx
spec:
rules:
- http:
paths:
- backend:
serviceName: svc2
servicePort: 80
path: /cacheable-path
