Earlier quoted context omitted.
If you spin up Kubernetes for "a couple of containers to run your web app", I think you're doing something wrong in the first place, also coupled with your comment about adding SDN to Kubernetes. People use Kubernetes for way too small things, and it sounds like you don't have the scale for actually running Kubernetes.
Doing Kubernetes like doing Agile is mandatory nowadays. I've been asked to package a 20 line worth of bash script as docker image so it can be delivered via CI/CD pipeline via Kubernetes pods in cloud. Value is not that I got job done at a day's notice. It is black mark that I couldn't package it as per industry best practices. Not doing would mean out of job/work. Whether it is happening correctly is not something…
Everyone else is communicating they are doing Agile while being very far away from it ;)
