- Fixed OpenAPI serialization of the x-kubernetes-validations field ([#107970](https://github.com/kubernetes/kubernetes/pull/107970), [@liggitt](https://github.com/liggitt))

## Build a Docker Image with a Single-File FastAPI { #build-a-docker-image-with-a-single-file-fastapi }

If your FastAPI is a single file, for example, `main.py` without an `./app` directory, your file structure could look like this:

```
.
├── Dockerfile
├── main.py
└── requirements.txt
```

Then you would just have to change the corresponding paths to copy the file inside the `Dockerfile`:

    assertThat(Ints.saturatedCast(Long.MIN_VALUE)).isEqualTo(LEAST);
  }

  private static void assertCastFails(long value) {
    try {
      Ints.checkedCast(value);
      fail("Cast to int should have failed: " + value);
    } catch (IllegalArgumentException ex) {
      assertWithMessage("%s not found in exception text: %s", value, ex.getMessage())
          .that(ex.getMessage().contains(String.valueOf(value)))
          .isTrue();

      TestCondition testCondition = create();

      ScheduledExecutorService scheduledPool = newScheduledThreadPool(1);
      // If signal() fails somehow, we should see a failed test, even without looking at the Future.
      Future<?> unused = scheduledPool.schedule(testCondition::signal, delay, unit);

      return testCondition;
    }

    static TestCondition create() {
