The kubernetes template holds data that controls the production of Kubernetes-specific
attributes.
Example config:
apiVersion: "config.istio.io/v1alpha2"
kind: kubernetes
metadata:
  name: attributes
  namespace: istio-system
spec:
  # Pass the required attribute data to the adapter
  source_uid: source.uid | ""
  source_ip: source.ip | ip("0.0.0.0") # default to unspecified ip addr
  destination_uid: destination.uid | ""
  destination_ip: destination.ip | ip("0.0.0.0") # default to unspecified ip addr
  attribute_bindings:
    # Fill the new attributes from the adapter produced output.
    # $out refers to an instance of OutputTemplate message
    source.ip: $out.source_pod_ip
    source.labels: $out.source_labels
    source.namespace: $out.source_namespace
    source.service: $out.source_service
    source.serviceAccount: $out.source_service_account_name
    destination.ip: $out.destination_pod_ip
    destination.labels: $out.destination_labels
    destination.namespace: $out.destination_mamespace
    destination.service: $out.destination_service
    destination.serviceAccount: $out.destination_service_account_name
OutputTemplate refers to the output from the adapter. It is used inside the attribute_binding section of the config
to assign values to the generated attributes using the $out.<field name of the OutputTemplate> syntax.

The kubernetes template represents data used to generate kubernetes-derived attributes.
The values provided controls the manner in which the kubernetesenv adapter discovers and generates values related to pod information. Next ID: 8
