Report #103754

[bug\_fix] Service exists but has no endpoints / traffic not reaching pods

Run \`kubectl get endpoints \` and compare the service \`selector\` with the pod labels. Ensure labels match exactly, pods are Ready, and the service targetPort matches the container's containerPort. If using NetworkPolicy, allow ingress from the source namespace or service CIDR.

Journey Context:
You create a Service and try to reach it, but \`curl\` times out. \`kubectl get svc\` shows a ClusterIP, but \`kubectl get endpoints\` is empty. You inspect the deployment labels \(\`app: web\`\) and the service selector \(\`app: website\`\). Because the selector does not match, the endpoints controller never adds pod IPs. After changing the service selector to \`app: web\`, endpoints populate and traffic flows. In another case the selector is correct but pods are not Ready because the readiness probe is failing on \`/healthz\`; fixing the probe path makes endpoints appear.
