Report #5069

[bug\_fix] Service has no endpoints / connection refused

Run kubectl get endpointslices -l kubernetes.io/service-name=. If endpoints are , compare the Service spec.selector with kubectl get pods --selector=... and ensure labels match exactly. Verify the Service targetPort matches the container's containerPort. Confirm pods are Ready by checking readiness probes. Once endpoints appear, kube-proxy can route traffic to the backing pods.

Journey Context:
A service returns connection refused. kubectl get endpointslices shows no endpoints even though pods are running. The Service selects app=frontend but the Deployment labels pods app=web. Updating the selector to app=web populates the EndpointSlice and traffic flows because kube-proxy now has backend pod IPs to load-balance to.

environment: Kubernetes Service of type ClusterIP, NodePort, or LoadBalancer backed by a Deployment or StatefulSet. · tags: service endpoints endpointslices selector targetport connection-refused kube-proxy readiness · source: swarm · provenance: https://kubernetes.io/docs/tasks/debug/debug-application/debug-service/
