OpenSergo CRD adapter for Sentinel Go (POC version)

NOTE: The Kubernetes operator logic was embedded in the POC data-source. This is only for demo. Please refer to https://github.com/opensergo/opensergo-specification/issues/17 for the canonical way to integrate with OpenSergo SDK.

Generate boilerplate code and OpenSergo CRD YAML:

make generate && make manifests

Install OpenSergo CRDs with:

kubectl apply -f config/crd/bases
