第 2 章 使用 RHACM 安装 OpenShift Data Foundation 逻辑卷管理器 Operator

流程

1. 使用您的 OpenShift 凭证登录 RHACM CLI。

   如需更多信息，请参阅安装 Red Hat Advanced Cluster Management for Kubernetes。

2. 创建命名空间。

   # oc create ns lvm-policy-ns

3. 在命名空间中创建策略 YAML。

   # This policy verifies the installation of the official version of the OpenShift Data Foundation
   # Logical Volume Manager Operator on the managed clusters.
   # If set to "enforce" it installs the operator.
   # Used APIs: OLM, ODF-LVMO #https://github.com/operator-framework/operator-lifecycle-manager
   # https://github.com/red-hat-storage/lvm-operator

            severity: high

4. 运行以下命令：

   # oc create -f policy-lvm-operator.yaml -n lvm-policy-ns

   这会创建 Policy、PlacementRule 和 PlacementBinding。Policy 创建一个命名空间、OperatorGroup、Subscription 和 LVMCluster 资源。这会在与选择条件匹配的 SNO 集群上部署 Operator，并将其配置为设置所需资源以置备存储。在安装后，Operator 会使用所有未使用的磁盘。
