红帽全球峰会27.15.2.2. CSI Driver DaemonSet
最后，CSI 驱动程序 DaemonSet 在每个节点上运行一个 pod，它允许 OpenShift Container Platform 挂载 CSI 驱动程序提供的存储，并使用它作为持久性卷 (PV) 的用户负载 (pod) 。安装了 CSI 驱动程序的 pod 包含以下容器：
-
CSI 驱动程序注册器，它会在节点上运行的
openshift-node服务中注册 CSI 驱动程序。在节点上运行的openshift-node进程然后使用节点上可用的 UNIX 域套接字直接连接到 CSI 驱动程序。 - CSI 驱动程序。
在节点上部署的 CSI 驱动程序应该在存储后端上有尽量少的凭证。OpenShift Container Platform 只使用节点插件的 CSI 调用集合，如 NodePublish/NodeUnpublish 和 NodeStage/NodeUnstage （如果已实施）。
