How to route request to two different backend based on request header

[raagulrakesh]

Hi;

I have doubt in route using request header in ingress

I am have two service as service-1 and service-2 as two backend and If I get header as service:1 it should redirect to service-1 backend as well as for service-2

@raagulrakesh Take a look at match and conditions:

https://docs.nginx.com/nginx-ingress-controller/configuration/virtualserver-and-virtualserverroute-resources/#match

This allows you to route based on a header to a specific service.

Hi
I am using only Ingress resource. Is there is any possibility to achieve this in Ingress resource

[jasonwilliams14]

You can do it with the ingress resource, but you would need to use snippets, allowing you to insert nginx configs directly into Ingress controller.
Then you would add the snippets to your Ingress resource to check for the incoming header, then route to the appropriate upstream (service) in kubernetes.
The CRD approach makes this easy to do and the above link has the capability built directly in to our project.

Hi @raagulrakesh, this is different project so I'd recommend opening a discussion/issue there or look at https://docs.nginx.com/nginx-ingress-controller/installation/ingress-nginx/ if you're open to moving to this project

thanks!
