CUE is a relatively young (but promising) programming language that enables working with data – building data structures, validating them, querying and extracting parts. More recently you might have run into CUE being used within several tools, such as Dagger (we’ve written about kapp and Dagger some time ago). In this post, we’ll dig into a few CUE examples for Kubernetes and see how we can use CUE and Carvel tools together.
