### **Cluster Federation**
#### Placement Policy
* [alpha] The federation-apiserver now supports a SchedulingPolicy admission controller that enables policy-based control over placement of federated resources. For more information, see [Set up placement policies in Federation](https://kubernetes.io/docs/tasks/federation/set-up-placement-policies-federation/).

**FastAPI**は、`OAuth2PasswordBearer` クラス (依存関係で宣言されている) を使用してOpenAPIのセキュリティスキームを定義できることを知っています。これは`fastapi.security.oauth2.OAuth2`、`fastapi.security.base.SecurityBase`を継承しているからです。

OpenAPIと統合するセキュリティユーティリティ (および自動APIドキュメント) はすべて`SecurityBase`を継承しています。それにより、**FastAPI**はそれらをOpenAPIに統合する方法を知ることができます。

## どのように動作するか

-   We can't move forward if these tests fail.
-   In such situations, we may request you to make further changes to your PR
    for the tests to pass.
-   Once the tests pass, we now bring all the code into the internal code base,
    using a job called "copybara".

**5. Copy to Google Internal codebase and run internal CI**

-   Once the PR is in the Google codebase, we make sure it integrates well with

// but merges the input shape with the existing shape.  For example,
// setting a shape of [-1, 2] with an existing shape [2, -1] would set
// a final shape of [2, 2] based on shape merging semantics.
//
// Returns an error into `status` if:
//   * `output` is not in `graph`.
//   * An invalid shape is being set (e.g., the shape being set
//     is incompatible with the existing shape).
