在配置Azure NetApp Files 后端之前、您需要确保满足以下要求。

备注 如果您是首次使用Azure NetApp Files 或在新位置使用、则需要进行一些初始配置来设置Azure NetApp Files 并创建NFS卷。请参见 "Azure：设置Azure NetApp Files 并创建NFS卷"。

NFS和SMB卷的前提条件

配置和使用 "Azure NetApp Files" 后端，您需要满足以下要求：

  • 一个容量池。请参见 "Microsoft：为Azure NetApp Files 创建容量池"。

  • 委派给Azure NetApp Files 的子网。请参见 "Microsoft：将子网委派给Azure NetApp Files"。

  • subscriptionID 从启用了Azure NetApp Files 的Azure订阅。

  • tenantID， clientID，和 clientSecret 从 "应用程序注册" 在 Azure Active Directory 中，具有足够的 Azure NetApp Files 服务权限。应用程序注册应使用以下任一项：

    • 所有者或贡献者角色 "由Azure预定义"。

    • 答 "自定义贡献者角色" 订阅级别 (assignableScopes)、并具有以下权限、这些权限仅限于Astra Trident所需的权限。创建自定义角色后、 "使用Azure门户分配角色"。

            }
        ]
    }
}

  • Azure location 至少包含一个 "委派子网"。自Trident 22.01日开始 location 参数是后端配置文件顶层的必填字段。在虚拟池中指定的位置值将被忽略。

SMB卷的其他要求

要创建SMB卷、您必须具有：

  • 已配置Active Directory并连接到Azure NetApp Files。请参见 "Microsoft：创建和管理Azure NetApp Files 的Active Directory连接"。

  • 一个Kubernetes集群、其中包含一个Linux控制器节点以及至少一个运行Windows Server 2019的Windows工作节点。Astra Trident仅支持将SMB卷挂载到Windows节点上运行的Pod。

  • 至少一个包含Active Directory凭据的Astra Trident密钥、以便Azure NetApp Files 可以向Active Directory进行身份验证。以生成密钥 smbcreds：

    kubectl create secret generic smbcreds --from-literal username=user --from-literal password='password'

  • 配置为Windows服务的CSI代理。配置 csi-proxy、请参见 "GitHub：CSI代理" 或 "GitHub：适用于Windows的CSI代理" 适用于在Windows上运行的Kubernetes节点。
