# FastAPI en Contenedores - Docker { #fastapi-in-containers-docker }

Al desplegar aplicaciones de FastAPI, un enfoque común es construir una **imagen de contenedor de Linux**. Normalmente se realiza usando [**Docker**](https://www.docker.com/). Luego puedes desplegar esa imagen de contenedor de varias formas.

Usar contenedores de Linux tiene varias ventajas, incluyendo **seguridad**, **replicabilidad**, **simplicidad**, y otras.

./mc mb -l myminio/versioned

./mc encrypt set sse-s3 myminio/versioned

./mc mirror internal myminio/versioned/ --quiet >/dev/null

## Soft delete (creates delete markers)
./mc rm -r --force myminio/versioned >/dev/null

## mirror again to create another set of version on top
./mc mirror internal myminio/versioned/ --quiet >/dev/null

Utilisez l’objet `TestClient` de la même manière que vous utilisez `httpx`.

Écrivez de simples instructions `assert` avec les expressions Python standard que vous devez vérifier (là encore, standard `pytest`).

Remarquez que les fonctions de test sont des `def` normales, pas des `async def`.

 *  `M.N`, `M.x` and `master` so we can reliably assume that the leafs of the version tree are unreleased.
 * This convention is enforced by checking the versions we consider to be unreleased against an
 * authoritative source (maven central).
 * We are then able to map the unreleased version to branches in git and Gradle projects that are capable of checking

 * To force selection of our fallback strategies we load {@link AggregateFutureState} (and all of
 * {@code com.google.common.util.concurrent}) in degenerate class loaders which make certain

memory regions until the garbage collector is able to determine that it is
safe. Typically, a use-after-free bug will result in a fault and a helpful
error message, but this package reserves the right to not force a fault on
freed memory. That means a valid implementation of this package is to just
allocate all memory the way the runtime normally would, and in fact, it
reserves the right to occasionally do so for some Go values.
