红帽全球峰会OpenShift Container Storage is now OpenShift Data Foundation starting with version 4.9.
3.2.3. 职责
这两个 ocs-operator CRD 是：
-
OCSInitialization -
StorageCluster
OCSInitialization 是一个单例 CRD，用于封装应用到 operator 级别的操作。操作器负责确保一个实例始终存在。CR 会触发以下内容：
执行 OpenShift Container Storage 所需的初始化任务。如果需要，可以通过删除
OCSInitializationCRD 来触发这些任务来再次运行。- 确保存在 OpenShift Container Storage 所需的安全性上下文约束(SCC)。
- 管理 Ceph toolbox Pod 的部署，用于执行高级故障排除和恢复操作。
StorageCluster CRD 代表提供 OpenShift Container Storage 完整功能的系统。它触发操作器，以确保 Rook-Ceph 和 NooBaa CRD 的生成与协调。ocs-operator 算法根据 StorageCluster spec 中的配置生成 CephCluster 和 NooBaa CRD。Operator 还会创建额外的 CR，如 CephBlockPools 和Routes 等。启用 OpenShift Container Storage 的不同功能需要这些资源。目前，每个 OpenShift Container Platform 集群只支持一个 StorageCluster CR。
