   * To avoid the need to call requireNonNull so much, we could consider more clever approaches,
   * such as:
   *
   * - Make checkOpen return the non-null `seq`. Then callers can assign that to a local variable or
   *   even back to `this.seq`. However, that may suggest that we're defending against concurrent

Mais cet exemple reste valable et montre comment interagir avec les composants internes.

Nous pouvons également utiliser cette même approche pour accéder au corps de la requête dans un gestionnaire d'exceptions.

Il suffit de traiter la requête dans un bloc `try`/`except` :

    attributes:
      label: 3. What would that same code look like if we added your feature?

        Comparing two approaches to a use case side by side can make it easier to examine the
        differences between them.


        Additionally, it's very useful to us if you can provide a "straw API" — what the

# FastAPI dans des conteneurs - Docker { #fastapi-in-containers-docker }

Lors du déploiement d'applications FastAPI, une approche courante consiste à construire une **image de conteneur Linux**. C'est généralement fait avec [**Docker**](https://www.docker.com/). Vous pouvez ensuite déployer cette image de conteneur de plusieurs façons possibles.

Use one of the following approaches to view job output:

View output in the Scala shell:

To view the output from MinIO exit the Scala shell. View WordCount job status:

### Examples of Replication Tools and Strategies { #examples-of-replication-tools-and-strategies }

There can be several approaches to achieve this, and I'll tell you more about specific strategies in the next chapters, for example when talking about Docker and containers.

// eliminate the comparison instruction, as bool values are guaranteed to be 0 or 1.
//
// The full 256-element table is used rather than a 128-element table to avoid
// additional operations in the lookup path. Alternative approaches were tested:
//   - [128]bool with explicit bounds check (if c >= 128): introduces branches
//     that cause pipeline stalls, resulting in ~70% slower performance

    * request a client certificate from the API server during the boot cycle and pause
    * waiting for the request to be satisfied. It will continually refresh the certificate
    * as the certificates expiration approaches.
