## Pasos Previos Antes de Iniciar { #previous-steps-before-starting }

Hay muchos casos en los que quieres realizar algunos pasos **antes de iniciar** tu aplicación.

Por ejemplo, podrías querer ejecutar **migraciones de base de datos**.

The [spec][rfc_7692] includes a sophisticated mechanism for client and server to negotiate
compression features. We strive to offer great performance in our default configuration and so we're
making compression the default for everyone starting with this release candidate.

Please be considerate of your servers and their operators as you roll out this release. Compression
saves bandwidth but it costs CPU and memory! If you run into a problem you may need to adjust or

如果这些关于 **容器**、Docker 或 Kubernetes 的内容还没有多大意义，请不要担心。

我将在以后的章节中向您详细介绍容器镜像、Docker、Kubernetes 等：[容器中的 FastAPI - Docker](docker.md)。

## 启动之前的步骤 { #previous-steps-before-starting }

在很多情况下，您希望在**启动**应用程序之前执行一些步骤。

例如，您可能想要运行**数据库迁移**。

但在大多数情况下，您只想执行这些步骤**一次**。

因此，在启动应用程序之前，您将需要一个**单个进程**来执行这些**前面的步骤**。

    } finally {
      this.socketAddress_ = boundSocketAddress
    }

    taskRunner.newQueue().execute(toString(), cancelable = false) {
      try {
        logger.fine("$this starting to accept connections")
        acceptConnections()
      } catch (e: Throwable) {
        logger.log(Level.WARNING, "$this failed unexpectedly", e)
      }

Если вы запускаете **несколько процессов в контейнере**, нужно убедиться, что их суммарное потребление **не превысит доступную память**.

## Предварительные шаги перед запуском и контейнеры { #previous-steps-before-starting-and-containers }

Если вы используете контейнеры (например, Docker, Kubernetes), есть два основных подхода.

### Несколько контейнеров { #multiple-containers }

## Changelog since v1.3.1

### Other notable changes

* List all nodes and occupy cidr map before starting allocations ([#29062](https://github.com/kubernetes/kubernetes/pull/29062), [@bprashanth](https://github.com/bprashanth))

Je vous en dirai plus sur les images de conteneurs, Docker, Kubernetes, etc. dans un chapitre à venir : [FastAPI dans des conteneurs - Docker](docker.md).

## Étapes préalables avant de démarrer { #previous-steps-before-starting }

Il existe de nombreux cas où vous souhaitez effectuer certaines étapes **avant de démarrer** votre application.

Par exemple, vous pourriez vouloir exécuter des **migrations de base de données**.

 * <p>Several lesser-used features are currently available only as static methods on the {@link

 * <h3>Comparison to streams</h3>
 *
 * <p>Starting with Java 8, the core Java class libraries provide a new "Streams" library (in {@code
 * java.util.stream}), which is similar to {@code FluentIterable} but generally more powerful. Key
 * differences include:
 *
 * <ul>

      // `entries`. The `oldNext` loop is going to traverse that linked list.
      // We need to rewrite the `next` link of each of the elements so that it is in the appropriate
      // linked list starting from `newTable`. In general, each element from the old linked list
      // belongs to a different linked list from `newTable`. We insert each element in turn at the
      // head of its appropriate `newTable` linked list.
