• Behavioral Changes
  • For Kubernetes 1.24+ the services of type LoadBalancer with appProtocol HTTP/HTTPS will switch to use HTTP/HTTPS as health probe protocol (while before v1.24.0 it uses TCP). And / will be used as the default health probe request path. If your service doesn’t respond 200 for /, please ensure you're setting the service annotation service.beta.kubernetes.io/port_{port}_health-probe_request-path or service.beta.kubernetes.io/azure-load-balancer-health-probe-request-path (applies to all ports) with the correct request path to avoid service breakage.
