安装 Data Grid Operator 时，它会使用自定义资源定义(CRD)扩展 Kubernetes API，以便在 Red Hat OpenShift 上部署和管理 Data Grid 集群。
要与 Data Grid Operator 交互，OpenShift 用户通过 OpenShift Web 控制台或 oc 客户端应用自定义资源(CR)。Data Grid Operator 侦听 Infinispan CR，并自动置备 Data Grid 部署所需的原生资源，如 StatefulSets 和 Secret。Data Grid Operator 还根据 Infinispan CR 中的规格配置数据网格服务，包括集群的 pod 数量以及跨站点复制的备份位置。
