Hi. The question might be silly, but I’m curious about it.
When I open a connection from pod to a pod on another node, does the host node get a port opened under the hood? Is there a difference if the two pods are hosted by the same node? Or does it depend on the actual implementation of k8s network model?
If I got it correctly, Services, Load Balancing, and Networking | Kubernetes implies that the network ports are not shared between different pods unless host ports are used.
