A GODEBUG setting is a `key=value` pair
that controls the execution of certain parts of a Go program.
The environment variable `GODEBUG`
can hold a comma-separated list of these settings.
For example, if a Go program is running in an environment that contains

	GODEBUG=http2client=0,http2server=0

then that Go program will disable the use of HTTP/2 by default in both
the HTTP client and the HTTP server.

它可以是另一个容器，例如使用 [Traefik](https://traefik.io/)，处理 **HTTPS** 并**自动**获取**证书**。

/// tip | 提示

Traefik 与 Docker、Kubernetes 等都有集成，因此为容器设置和配置 HTTPS 非常容易。

///

或者，HTTPS 也可能由云服务商作为其服务之一提供（应用仍运行在容器中）。

## 启动时运行与重启 { #running-on-startup-and-restarts }

通常会有另一个工具负责**启动并运行**你的容器。

它可以是直接的 **Docker**、**Docker Compose**、**Kubernetes**、某个**云服务**等。

在大多数（或全部）情况下，都有简单选项可以在开机时运行容器并在失败时启用重启。例如，在 Docker 中是命令行选项 `--restart`。

This program starts a goroutine for every entry in the work list, but the
goroutines coordinate using the <code>limit</code> channel to ensure
that at most three are running work functions at a time.
</p>

<pre>
var limit = make(chan int, 3)

func main() {
	for _, w := range work {
		go func(w func()) {
			limit &lt;- 1
			w()
			&lt;-limit
		}(w)

## 查看自动化的 API 文档 { #check-the-automatic-api-docs }

现在，运行你的应用：

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

然后打开位于 [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs) 的文档。

你将看到使用了正确路径（和前缀）和正确标签的自动化 API 文档，包括了来自所有子模块的路径：

Альтернативно, HTTPS може оброблятись хмарним провайдером як один з їхніх сервісів (при цьому застосунок усе ще працює в контейнері).

## Автозапуск і перезапуски { #running-on-startup-and-restarts }

Зазвичай інший інструмент відповідає за запуск і виконання вашого контейнера.

Це може бути безпосередньо Docker, Docker Compose, Kubernetes, хмарний сервіс тощо.

Alternativamente, o HTTPS poderia ser tratado por um provedor de nuvem como um de seus serviços (enquanto ainda executasse o aplicativo em um contêiner).

## Executando na inicialização e reinicializações { #running-on-startup-and-restarts }

Normalmente, outra ferramenta é responsável por **iniciar e executar** seu contêiner.

Ela poderia ser o **Docker** diretamente, **Docker Compose**, **Kubernetes**, um **serviço de nuvem**, etc.
