Crossplane compositions vs Helm – when to pick what?
One thing I appreciate about Crossplane: compositions aggregate status from all resources back to the XR. You get direct feedback on your cloud resources, not just “deploy and forget” like with Helm. Plus you can use existing cluster resources to adjust how the composition behaves.
And you get a typed API contract via the XRD with OpenAPI schema that actually enforces at admission. Helm values only validate if you set up JSON schema – which many skip.
As always: it depends. But for advanced use cases where you need more than just resource deployment, there are good reasons.
