gRPC Connection Refused
Symptom: connect: connection refused
Diagnosis:
# Check service is running
kubectl get pods -n foxhunt -l app.kubernetes.io/component=trading-service
# Check service endpoint
kubectl get endpoints -n foxhunt foxhunt-trading-service
# Test connection
grpc_health_probe -addr=foxhunt-trading-service.foxhunt.svc.cluster.local:50052
Resolution:
# Restart service
kubectl rollout restart deployment/foxhunt-trading-service -n foxhunt
# Check logs for startup errors
kubectl logs -n foxhunt -l app.kubernetes.io/component=trading-service --tail=100
DNS Resolution Failures
Symptom: no such host
Diagnosis:
# Check CoreDNS
kubectl get pods -n kube-system -l k8s-app=kube-dns
# Test DNS resolution
kubectl run -it --rm debug --image=nicolaka/netshoot --restart=Never -- \
nslookup foxhunt-postgresql.foxhunt.svc.cluster.local
Resolution:
# Restart CoreDNS
kubectl delete pods -n kube-system -l k8s-app=kube-dns
# Verify DNS resolution
kubectl run -it --rm debug --image=nicolaka/netshoot --restart=Never -- \
dig foxhunt-postgresql.foxhunt.svc.cluster.local
