#### Debug logging
To enable debug logging:
```
kubectl -n ingress-nginx patch ds nginx-ingress-controller --type='json' -p='[{"op": "add", "path": "/spec/template/spec/containers/0/args/-", "value": "--v=5"}]'
```
#### Check configuration
Retrieve generated configuration in each pod:
```
kubectl -n ingress-nginx get pods -l app=ingress-nginx --no-headers -o custom-columns=.NAME:.metadata.name | while read pod; do kubectl -n ingress-nginx exec $pod -- cat /etc/nginx/nginx.conf; done
```
### Rancher agents
Communication to the cluster (Kubernetes API via `cattle-cluster-agent`) and communication to the nodes (cluster provisioning via `cattle-node-agent`) is done through Rancher agents.
