```Dockerfile
FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7

COPY ./app /app
```

#### Grandes aplicações

Se você seguiu a seção sobre criação de [Grandes Aplicações com Múltiplos Arquivos](tutorial/bigger-applications.md){.internal-link target=_blank}, seu `Dockerfile` poderia parecer como:

```Dockerfile
FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7

COPY ./app /app/app
```

}

function cidr_to_ips() {
    CIDR="$1"
    # cidr_to_ips returns a list of single IPs from a CIDR. We skip 1000 (since they are likely to be allocated
    # already to other services), then pick the next 100.
    python3 - <<EOF
from ipaddress import ip_network, IPv6Network;
from itertools import islice;

net = ip_network('$CIDR')
net_bits = 128 if type(net) == IPv6Network else 32;
net_len = pow(2, net_bits - net.prefixlen)

Beispielsweise gibt es ein offizielles <a href="https://hub.docker.com/_/python" class="external-link" target="_blank">Python-Image</a>.

Und es gibt viele andere Images für verschiedene Dinge wie Datenbanken, zum Beispiel für:

* <a href="https://hub.docker.com/_/postgres" class="external-link" target="_blank">PostgreSQL</a>

For example, there's an official <a href="https://hub.docker.com/_/python" class="external-link" target="_blank">Python Image</a>.

And there are many other images for different things like databases, for example for:

* <a href="https://hub.docker.com/_/postgres" class="external-link" target="_blank">PostgreSQL</a>

Por exemplo, há uma <a href="https://hub.docker.com/_/python" class="external-link" target="_blank">Imagem Python</a> oficial.

E existe muitas outras imagens para diferentes coisas, como bancos de dados, por exemplo:

* <a href="https://hub.docker.com/_/postgres" class="external-link" target="_blank">PostgreSQL</a>

```bash
clang-format <my_cc_file> --style=google > /tmp/my_cc_file.cc
diff <my_cc_file> /tmp/my_cc_file.cc
```

#### Python coding style

Changes to TensorFlow Python code should conform to
[Google Python Style Guide](https://github.com/google/styleguide/blob/gh-pages/pyguide.md)

Use `pylint` to check your Python changes. To install `pylint` and check a file
with `pylint` against TensorFlow's custom style definition:

```bash

* ⏮️ ☁ 🐝 📳 🌑
* ⏮️ ➕1️⃣ 🧰 💖 🖖
* ⏮️ ☁ 🐕‍🦺 👈 ✊ 👆 📦 🖼 & 🛠️ ⚫️

## ☁ 🖼 ⏮️ 🎶

🚥 👆 ⚙️ <a href="https://python-poetry.org/" class="external-link" target="_blank">🎶</a> 🛠️ 👆 🏗 🔗, 👆 💪 ⚙️ ☁ 👁-▶️ 🏗:

```{ .dockerfile .annotate }
# (1)

例如，有一个官方的 <a href="https://hub.docker.com/_/python" class="external-link" target="_blank">Python 镜像</a>。

还有许多其他镜像用于不同的需要（例如数据库），例如：


* <a href="https://hub.docker.com/_/postgres" class="external-link" target="_blank">PostgreSQL</a>
* <a href="https://hub.docker.com/_/mysql" class="external-link" target="_blank">MySQL</a>

* 노마드 같은 다른 도구로 배포하기
* 여러분의 컨테이너 이미지를 배포해주는 클라우드 서비스로 배포하기

## Poetry의 도커 이미지

만약 여러분들이 프로젝트 의존성을 관리하기 위해 <a href="https://python-poetry.org/" class="external-link" target="_blank">Poetry</a>를 사용한다면, 도커의 멀티-스테이지 빌딩을 사용할 수 있습니다:

```{ .dockerfile .annotate }
# (1)
FROM python:3.9 as requirements-stage

# (2)
WORKDIR /tmp

# (3)
RUN pip install poetry

# (4)

Docker Hubは 多くのツールや環境、データベース、アプリケーションに対応している予め作成された**公式のコンテナ・イメージ**をパブリックに提供しています。

例えば、公式イメージの1つに<a href="https://hub.docker.com/_/python" class="external-link" target="_blank">Python Image</a>があります。

その他にも、データベースなどさまざまなイメージがあります：

* <a href="https://hub.docker.com/_/postgres" class="external-link" target="_blank">PostgreSQL</a>
