## gRPC Connection Refused
|
|
|
|
### Symptom: `connect: connection refused`
|
|
|
|
**Diagnosis**:
|
|
```bash
|
|
# 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**:
|
|
```bash
|
|
# 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**:
|
|
```bash
|
|
# 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**:
|
|
```bash
|
|
# 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
|
|
```
