The service-binding trait populates environment variables with information extracted from Kubernetes secrets. These secrets can be created using the storage trait, by using a k8s-object component to render the secret, or directly with creating the
Secret kubernetes entities with
kubectl or with a deploy operation.
The following snippet describes an application with a component that populates environemnt variables from an existing secret.
