## 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**
