## Deploy categraf as daemonset

edit k8s/daemonset.yaml, replace NSERVER_SERVICE_WITH_PORT with service ip:port of nserver in your cluster, replace CATEGRAF_NAMESPACE with namespace value, then run:

```shell
kubectl apply -n monitoring -f ks8/daemonset.yaml
kubectl apply -n monitoring -f ks8/sidecar.yaml
```
notice: k8s/sidecar.yaml is a demo, replace mock with your own image.
