What if platform teams could offer self-service infrastructure without exposing implementation details?
In this talk, we explore how Kubernetes Custom Resources serve as a truly declarative platform API, enabling teams to declare intent rather than manage configuration.
Using Crossplane Compositions as a transformation engine, we show how high-level declarations are turned into infrastructure resources through a two-stage process — including fully declarative multi-tenant onboarding. No imperative glue code, no event-driven reconciliation, no cognitive overload. Just declare, commit, deploy. We share real-world patterns and lessons learned.
- Crossplane basics are helpful but not required.
- Attendees will learn how to design Kubernetes Custom Resources as a declarative platform API that abstracts infrastructure details from teams.
- They will understand a proposed two-stage composition process using Crossplane - from intent to topology to infrastructure — and how this same pattern enables fully declarative multi-tenant onboarding without imperative processing.
