and you are already setting **replication** at the cluster level, with multiple **containers**. In those cases, you are better off **building an image from scratch** as described above: [Build a Docker Image for FastAPI](#build-a-docker-image-for-fastapi).

This image would be useful mainly in the special cases described above in [Containers with Multiple Processes and Special Cases](#containers-with-multiple-processes-and-special-cases). For example, if your application is **simple enough**...

## Repaso

* Importa `FastAPI`.
* Crea un instance de `app`.
* Escribe un **decorador de operación de path** (como `@app.get("/")`).
* Escribe una **función de la operación de path** (como `def root(): ...` arriba).

    // Note that this may be be an encoded "end of data" header.
    return DerHeader(tagClass, tag, constructed, length)
  }

  /**
   * Consume a header and execute [block], which should consume the entire value described by the
   * header. It is an error to not consume a full value in [block].
   */
  internal inline fun <T> read(
    name: String?,
    block: (DerHeader) -> T,
  ): T {

message PodSchedulingContext {
  // Standard object metadata
  // +optional
  optional k8s.io.apimachinery.pkg.apis.meta.v1.ObjectMeta metadata = 1;

  // Spec describes where resources for the Pod are needed.
  optional PodSchedulingContextSpec spec = 2;

  // Status describes where resources for the Pod can be allocated.
  // +optional
  optional PodSchedulingContextStatus status = 3;
}

have a model with all the attributes marked as optional (with default values or `None`).

    To distinguish from the models with all optional values for **updates** and models with required values for **creation**, you can use the ideas described in [Extra Models](extra-models.md){.internal-link target=_blank}....

// This is a subresource of Pod.  A request to cause such an eviction is
// created by POSTing to .../pods/<pod name>/evictions.
message Eviction {
  // ObjectMeta describes the pod that is being evicted.
  // +optional
  optional k8s.io.apimachinery.pkg.apis.meta.v1.ObjectMeta metadata = 1;

  // DeleteOptions may be provided
  // +optional

!!! warning
    Existe uma grande chance de que você **não** precise dessa imagem base ou de qualquer outra semelhante, e seria melhor construir a imagem do zero, como [descrito acima em: Construa uma Imagem Docker para o FastAPI](#construindo-uma-imagem-docker-para-fastapi).

  - `PodSpec.Container.ResizePolicy` (new object) gives users control over how their containers are resized.
  - `PodStatus.Resize` status describes the state of a requested Pod resize.
  - `PodStatus.ResourcesAllocated` describes node resources allocated to Pod.
  - `PodStatus.Resources` describes node resources applied to running containers by CRI.

## Notas

Cuando devuelves una `Response` directamente, los datos no son validados, convertidos (serializados), ni documentados automáticamente.

Pero todavía es posible documentarlo como es descrito en [Respuestas adicionales en OpenAPI](additional-responses.md){.internal-link target=_blank}.
