I am a newbie in Kubernetes arena. I was reading abt the Kubernetes networking and understood that as soon as a POD is created, it is assigned an IP . But POD is a logical entity which is a collection of containers. Does POD have any ethernet interface to which this IP is assigned ? Can you please provide some detailed info on this ?
As you understood already that POD is just a logical entity, there is no ethernet interface attached to it. The containers launched inside the (logical) pod is mapped to same network with the docker's --net option. Some explanation about docker mapping to same network here: docker-containers-same-internal-ip
