Run network performance test in kubernetes cluster

k8s-iperf

Modified from kubernetes-iperf3 to benchmark kubernetes cluster network performance. Will use iperf to measure network performance with multiple connections from each nodes.

How to use

Select a node as iperf server, and all the other nodes in kubernetes cluster will try to connect to server at the same time.

./k8s-iperf <server-node>

Output
