## 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**

  static int log10Floor(long x) {
    /*
     * Based on Hacker's Delight Fig. 11-5, the two-table-lookup, branch-free implementation.
     *
     * The key idea is that based on the number of leading zeros (equivalently, floor(log2(x))), we
     * can narrow the possible floor(log10(x)) values to two. For example, if floor(log2(x)) is 6,
     * then 64 <= x < 128, so floor(log10(x)) is either 1 or 2.
