The Kubernetes ecosystem is rife with tools like this, and it feels like such a chore to just keep up with every new templating system for YAML files. I have started to just write Go programs that directly talk to the Kubernetes API and manage my rollouts (one step away from operators).
It's more curly brackets than YAML :)
Instead, kpt's key design philosophy is to keep configuration as data. This makes it easier to develop tooling that operate on configs.
If you are going to introduce a new tool into an already crowded ecosystem the least you can do is describe why anyone should use it.
Kpt is an OSS tool for Kubernetes packaging. It uses a standard format to bundle, publish, customize, update, and apply configuration manifests. Kpt operates like kubectl, providing additional functionality to prune and delete configuration.
