红帽全球峰会2.3. 启用 SiteConfig operator
启用 SiteConfig Operator，以使用默认的安装模板，并大规模安装单节点 OpenShift 集群。
需要的访问权限：集群管理员
2.3.1. 先决条件
- 您需要一个 Red Hat Advanced Cluster Management hub 集群。
2.3.2. 从 MultiClusterHub 资源启用 SiteConfig operator
对 MultiClusterHub 资源进行补丁，然后验证是否启用了 SiteConfig operator。完成以下步骤：
运行以下命令，设置与
MultiClusterHuboperator 的命名空间匹配的环境变量：export MCH_NAMESPACE=<namespace>
Copy to clipboardCopiedexport MCH_NAMESPACE=<namespace>运行以下命令，在
Multiclusterhub资源中的spec.overrides.components的siteconfig条目中将enabled字段设置为true：oc patch multiclusterhubs.operator.open-cluster-management.io multiclusterhub -n ${MCH_NAMESPACE} --type json --patch '[{"op": "add", "path":"/spec/overrides/components/-", "value": {"name":"siteconfig","enabled": true}}]'

oc -n ${MCH_NAMESPACE} get po | grep siteconfig
Copy to clipboardCopiedoc -n ${MCH_NAMESPACE} get po | grep siteconfig请参见以下示例输出：

oc -n ${MCH_NAMESPACE} get cm
Copy to clipboardCopiedoc -n ${MCH_NAMESPACE} get cm请参阅输出示例中的以下模板列表：
