Extensions API group): Kubernetes can schedule a service (such as a logging
agent) that runs one, and only one, pod per node.
     * TLS and L7 support (Ingress API (Beta) in the Extensions API group): Kubernetes
is now easier to integrate into custom networking environments by supporting
TLS for secure communication and L7 http-based traffic routing.

- Changed how the API server handles updates to `.spec.defaultBackend` of Ingress objects.

    * 2. A cluster can be dualstack (i.e. Pods and nodes carry dualstack IPs) but does not need to support ingress on dualstack. In this case the cluster can perform egress using `PodIPs` (according to family and binding selection in user code) but will ingress will only be performed against the pod primary IP. This can be configured by supplying single entry to `--service-cluster-ip-range` flag.

### 创建数据

现在创建工具函数来创建数据。

它的步骤是：

* 使用您的数据创建一个 SQLAlchemy 模型*实例。*
* 使用`add`来将该实例对象添加到数据库会话。
* 使用`commit`来将更改提交到数据库（以便保存它们）。
* 使用`refresh`来刷新您的实例对象（以便它包含来自数据库的任何新数据，例如生成的 ID）。

```Python hl_lines="18-24  31-36"
{!../../docs_src/sql_databases/sql_app/crud.py!}
```

/// tip

SQLAlchemy 模型`User`包含一个`hashed_password`，它应该是一个包含散列的安全密码。
