I’m dealing with a strange issue. I have some containers that are trying to send TCP requests to a service within K8s cluster, but somehow these requests are routed outside K8s.
They hit a perimeter firewall.
The service doesn’t have any endpoints because the backing pods are failing to start, so I accept that requests to the service will fail, but I wasn’t expecting these requests to be routed elsewhere.
Any idea what could be causing this?
