Domain Specific Language

Being able to write Kubewarden policies using regular programming languages provides many advantages, however in certain cases this could be a bit of an overkill. Simple policies could be written in an easier way using a domain-specific language.

This is an extract from the Wikipedia page about domain-specific languages:

A domain-specific language (DSL) is a computer language specialized to a particular application domain.

We plan to provide a simple DSL that can be built as a Wasm module. This would allow the Kubewarden admission controller to use policies written using regular programming languages and policies written a simpler DSL language.
