I'm aware that an overlay network is used to allow pod to pod communication. I'm not sure of how to trace the network setup that a packet will use. For instance how do start with a pod name and trace the packets going from that pod to another pod in the cluster? How can I see which networking hops it makes in the overlay, host, and possibly vpc network?

I know this is kind of many questions, but I feel like the pieces are likely buring in a string of commands like kubectl to get the IP of the POD and then ip route and ip addr to see the interfaces and then since I'm using flannel maybe some iptabels-save call. I know this much, but I'm not very familiar with these tools, nor know what to specifically to look for yet.
