External-DNS: NodePort must not publish not ready pods
What happened:
NodePort Traffic policy: Local
Service with NodePort correctly update endpoints and does not try to publish not ready pods ExternalDNS use internal logic to find pods by selector labels (instead of reading endpoints object) and only checks state isRunning (https://github.com/kubernetes-sigs/external-dns/blob/0bf5faed42215ce20533de385bb6dccde10c4ab1/source/service.go#L568) (Bad behavior: https://github.com/kubernetes/client-go/issues/815)
What you expected to happen:
When I try to remove the pod and its moves to terminate state, external-dns that watching NodePort service will stop publishing node with the pod, not in a ready state. Looks like we need additionally check pods by IsPodReady()
How to reproduce it (as minimally and precisely as possible):
Create service with NodePort type and with traffic policy Local pointing to some pods, add some lifecycle preStop look like sleep 60, after that delete pod and look at external-dns - it still publishes pod in terminating state.
Environment:
- External-DNS version (use
external-dns --version): 0.11 - DNS provider: Route53
