Hi there,
I'm struggling to find out how to specify a different kubernetes namespace within a ingressroute.
For example I have a k8s service 'ping' in the namespace 'test' and want to reference this from an ingressroute in a namespace called 'app'.
I have tried the normal k8s style ping.test but this errors
Any hints?
Thank
Hi @Craig.millard, as suggested in the official Kubernetes project tracker: https://github.com/kubernetes/kubernetes/issues/17088 , this is something not available by design with Ingresses.
With the IngressRoute
, we are following this behaviour as well, because it's related to Kubernetes internals (and security).
What is the reason that make you store IngressRoute object in a different namespace than the Service object?
As an (heavy) alternative, you can create a "fake" service of type externalName
, in the same namespace as the Ingressroute. Then, set the externalDNS name to the service you want to reach in the form <service>.<namespace>.<cluster doamin>
(see https://kubernetes.io/docs/concepts/services-networking/dns-pod-service/#services for more informations).
