Sample custom resource

This is a sample custom resource (CR) that the API Gateway Controller listens for to expose a service. This example has the rules section specified which makes the API Gateway Controller create an Oathkeeper Access Rule for the service.

v1beta1
v1alpha1

The following tables list all the possible parameters of a given resource together with their descriptions:

CAUTION: If service is not defined at spec.service level, all defined rules must have service defined at spec.rules.service level, otherwise the validation fails.
