URL application redirection

Hi folks,
Sorry if the question is dumb but I’m just starting up with kong.

I’ve manage to setup kong + metallb in a k8s cluster. I’ve also been able to access two apps by deploying an ingress and a service.
My issue is that I know one of the app needs to redirect to a specific page. When I’m using the same app in a simple docker container, if I hit it on it’s port, it will redirect me like :
localhost:3001 → localhost:3001/status/default

When deployed in my k8s cluster, there is no redirection, it stays at :
localhost/foo

I don’t really know where to start to tackle the issue :zipper_mouth_face:
Should I use a plugging or something ?

Thanks !
