Creating Dynamic Kubernetes Resources with Crossplane Functions
summary
Crossplane adds executable Composition Functions that run as an OCI image and communicate over gRPC + mTLS, accept a protobuf payload of desired/observed resources, mutate that JSON/YAML stream, and emit the modified resources. A demo pipeline runs a patch/transform step to create an AWS VPC and Internet Gateway, then a function that adds labels and annotations to every generated object — the resources provision successfully. Functions are stateless, language-agnostic (Go SDK available, Python planned), and v1beta1 targets Crossplane 1.14 (late October).
