The “cf push – experience” saying is related to simplify some of cloud native development tasks for developers. I haven’t found an official definition for that “cf push – experience” saying, so I just define one by myself. Of course, I found videos and longer implicit descriptions and one awesome description you can find in the YouTube video Kube Your Enthusiasm — Bringing the `CF Push` Experience to Kubernetes Operators (Project Eirini) and Onsi Fakhouri did also a tweet cf push haiku a long time ago in 2015 related to cf push.
But here is my personal definition:
“The Developers “cf push – experience” is: Developers can focus on implementing functional requirements in a programming language and they don’t wasting additional time to extra define network or container configuration to deploy an executable application into the cloud.”
