# Full example for Kubernetes running as daemonset (in-cluster k8s config)
# Requires environment variables:
# - KUBERNETES_SERVICE_HOST - provided by default by Kuberenetes
# - KUBERNETES_SERVICE_PORT - provided by default by Kubernetes
# - HOST_IP - need to explicitly enabled in Pod spec using downward-api
# - HOSTNAME - default provided by OS

# Example to enable WSS heuristic debugging.
