In the previous post, I mentioned that CUE can help you work with both “industry-standard” semi-structured APIs and fully structured APIs where data is modelled using OpenAPI or JSON schema. However, there was an elephant in the room that I conveniently ignored but without which no conversation about network automation would be complete. With this post, I plan to rectify my previous omission and explain how you can use CUE to work with YANG-based APIs.
