Networking latency measurement in Kubernetes with Sockperf plugin

This document will provide a simple implementation of a kubectl plugin used for latency measurements between two Pods on a Kubernetes cluster. It can be run as a standalone bash script or as plugin with kubectl binary after copying the script content in somewhere in the local PATH.

This script uses the sockperf binary installed in pre-existing Pods in the AKS environment. It has been tested with a nginx based image container as in the sockpers is already present in the standard repositories. As it is using the kubectl to interact with AKS cluster, we need to have the binary installed and configured with proper credentials.

The plugin can be run as follows:

By default, the client-side tests will run for 100 seconds, the results will be available on the stdout after the test finishes.
