## Construire une image Docker pour FastAPI { #build-a-docker-image-for-fastapi }

Très bien, construisons quelque chose maintenant ! 🚀

Je vais vous montrer comment construire une **image Docker** pour FastAPI **à partir de zéro**, basée sur l'image **officielle Python**.

C'est ce que vous voudrez faire dans **la plupart des cas**, par exemple :

* Utiliser **Kubernetes** ou des outils similaires
* Exécuter sur un **Raspberry Pi**

pkg crypto/tls, type Config struct, GetCertificate func(*ClientHelloInfo) (*Certificate, error)
pkg crypto/tls, type ConnectionState struct, TLSUnique []uint8

# CL 153420045 crypto/x509: continue to recognise MaxPathLen of zero as "no value"., Adam Langley <******@****.***>
pkg crypto/x509, type Certificate struct, MaxPathLenZero bool

# CL 158950043 database/sql: add Drivers, returning list of registered drivers, Russ Cox <******@****.***>

    sizesToTest.retainAll(features);
    features.removeAll(sizesToTest);

    addImpliedFeatures(sizesToTest);
    sizesToTest.retainAll(asList(CollectionSize.ZERO, CollectionSize.ONE, CollectionSize.SEVERAL));

    logger.fine("   Sizes: " + formatFeatureSet(sizesToTest));

    if (sizesToTest.isEmpty()) {
      throw new IllegalStateException(
          name

	Err  error     // Error returned by the remote peer for an rpc call
}

// A NotificationGroup is a collection of goroutines working on subtasks that are part of
// the same overall task.
//
// A zero NotificationGroup is valid and does not cancel on error.
type NotificationGroup struct {
	workers    *workers.Workers
	errs       []NotificationPeerErr
	retryCount int
}

 * Comparator} or {@link Comparable} type whose comparison behavior is <i>inconsistent with
 * equals</i>. That is, {@code a.compareTo(b)} or {@code comparator.compare(a, b)} should equal zero
 * <i>if and only if</i> {@code a.equals(b)}. If this advice is not followed, the resulting
 * collection will not correctly obey its specification.

## Construir uma Imagem Docker para FastAPI { #build-a-docker-image-for-fastapi }

Okay, vamos construir algo agora! 🚀

Eu vou mostrar como construir uma **imagem Docker** para FastAPI **do zero**, baseada na imagem **oficial do Python**.

Isso é o que você quer fazer na **maioria dos casos**, por exemplo:

* Usando **Kubernetes** ou ferramentas similares
* Quando rodando em uma **Raspberry Pi**

    sizesToTest.retainAll(features);
    features.removeAll(sizesToTest);

    addImpliedFeatures(sizesToTest);
    sizesToTest.retainAll(asList(CollectionSize.ZERO, CollectionSize.ONE, CollectionSize.SEVERAL));

    logger.fine("   Sizes: " + formatFeatureSet(sizesToTest));

    if (sizesToTest.isEmpty()) {
      throw new IllegalStateException(
          name

   * won't cause a rehash.
   *
   * <p>As of jdk7u40, HashMap has an empty-map optimization. The argument to new HashMap(int) is
   * noted, but the initial table is a zero-length array.
   *
   * <p>This test may fail miserably on non-OpenJDK environments...
