222. 如何更新 RKE2 集群中的默认 ingress-nginx 证书

The default SSL certificate for ingress-nginx can be updated in the rke2-ingress-nginx Helm chart via the value controller.extraArgs.default-ssl-certificate. This value should reference the namespace and name of a TLS secret that you have already created in the cluster. This value can be defined in an RKE2 cluster via a HelmChartConfig, as described in this article.
ingress-nginx 的默认 SSL 证书可以通过 value controller.extraArgs.default-ssl-certificate，在 rke2-ingress-nginx Helm 图表中更新。这个值应指向你在集群中已创建的 TLS 秘密的命名空间和名称。该值可以通过 HelmChartConfig 在 RKE2 集群中定义，如本文所述。

1. Login to the Rancher UI
   登录牧场主界面
2. Navigate toCluster Management
   导航至集群管理
3. ClickEdit Configfor the relevant Rancher-provisioned RKE2 cluster
   点击编辑配置以查看相关的 Rancher 配置 RKE2 集群
4. ClickAdditional Manifestand provide the a HelmChartConfig, with the desired default-ssl-certificate, per the example below, setting <namespace> and <secret_name> as required to reference the appropriate TLS secret.
   点击“附加清单”，提供 HelmChartConfig，并按照下面的示例设置所需的默认 SSL 证书，设置<namespace> 和<secret_name>，以引用相应的 TLS 秘密。

Configuration for standalone RKE2 clusters
独立 RKE2 集群配置

On server nodes in the cluster, create a HelmChartConfig manifest, with the desired default-ssl-certificate, for the rke2-ingress-nginx chart, within the directory /var/lib/rancher/rke2/server/manifests/ (e.g. /var/lib/rancher/rke2/server/manifests/rke2-ingress-nginx-config.yaml). In the example below, set <namespace> and <secret_name> as required to reference the appropriate TLS secret.
在集群中的服务器节点上，创建一个 HelmChartConfig 清单，包含所需的默认 ssl 证书，用于 rke2-ingress-nginx 图表，目录为/var/lib/rancher/rke2/server/manifests/（例如/var/lib/rancher/rke2/server/manifests/rke2-ingress-nginx-config.yaml）。在下面的示例中，设置<namespace>和 <secret_name> 如要求引用相应的 TLS 秘密。
