## Deploy categraf as daemonset, deployment or sidecar
|
|
|
|
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 k8s/daemonset.yaml # collect metrics, metrics/cadvisor of node
|
|
kubectl apply -n monitoring -f k8s/sidecar.yaml # collect service metrics
|
|
kubectl apply -n monitoring -f k8s/deployment.yaml #collect apiserver coredns etc
|
|
```
|
|
Notice: k8s/sidecar.yaml is a demo, replace mock with your own image of service.
