**Result:** You have confirmed that you can access the cluster with `kubectl` and the RKE2 cluster is running successfully. Now the Rancher management server can be installed on the cluster.
### 5. Configure nginx to be a daemonset
Currently, RKE2 deploys nginx-ingress as a deployment, and that can impact the Rancher deployment so that you cannot use all servers to proxy requests to the Rancher pods.
To rectify that, place the following file in /var/lib/rancher/rke2/server/manifests on any of the server nodes:
```yaml
apiVersion: helm.cattle.io/v1
kind: HelmChartConfig
metadata:
name: rke2-ingress-nginx
namespace: kube-system
spec:
valuesContent: |-
controller:
kind: DaemonSet
daemonset:
useHostPort: true
```
