RKE2默认没有开启ServiceLB，因此Nginx Ingress也没有创建LoadBalance Service，而是使用的Hostport + Daemonset的方式。

开启ServiceLBH2

参数--enable-servicelb在官方文档中没有提及Configuration Options | RKE2。 这里Allow enabling ServiceLB controller · Issue #3419 · rancher/rke2 (github.com)提及到，可以通过设置enable-servicelb参数到/etc/rancher/rke2/config.yaml 来启用。

开启Nginx Ingress的LoadBalance ServiceH2

Configuration options can be specified by creating a HelmChartConfig manifest to customize the rke2-==ingress==-nginx HelmChart values. For example, a HelmChartConfig at /var/lib/rancher/rke2/server/manifests/rke2-==ingress==-nginx-config.yaml with the following contents sets use-forwarded-headers to "true" in the ConfigMap storing the NGINX config:

bash
# /var/lib/rancher/rke2/server/manifests/rke2-ingress-nginx-config.yaml
---
apiVersion: helm.cattle.io/v1
kind: HelmChartConfig
metadata:
  name: rke2-ingress-nginx
  namespace: kube-system
spec:
  valuesContent: |-
    controller:
      config:
        service:
          enabled: true
