创建和管理池

本页面介绍了如何创建和管理 Live Stream API 池。池是为每个 Google Cloud 项目按区域分配的处理单元，并且在给定区域中的所有频道之间共享。池用于保护 VPC Service Controls 边界内的输入端点。如需了解详情，请参阅使用 VPC Service Controls 保护流水线。

设置您的 Google Cloud 项目和身份验证

如果您尚未创建 Google Cloud 项目和凭据，请参阅准备工作。

创建池

首次在某个位置创建输入端点时，系统会自动为该位置创建默认池。

获取池详情

如需获取池的详情，请使用 projects.locations.pools.get 方法。
