C'est une chose différente.

On utilise un deux-points (`:`), et pas un égal (`=`).

Et ajouter des annotations de types ne crée normalement pas de différence avec le comportement qui aurait eu lieu si elles n'étaient pas là.

Maintenant, imaginez que vous êtes en train de créer cette fonction, mais avec des annotations de type cette fois.

        hackBuildPhase.setShellScript("# Script to generate specific Swift files Xcode expects when running tests.\n"

            + "do\n"
            + "  for SUFFIX in \"${SUFFIXES[@]}\"\n"

Mas não é possível ter um contêiner rodando sem **pelo menos um processo rodando**. Se o processo principal parar, o contêiner também para.

## Construindo uma Imagem Docker para FastAPI

Okay, vamos construir algo agora! 🚀

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

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