### 依赖

这同样适用于[依赖](tutorial/dependencies/index.md){.internal-link target=_blank}。如果一个依赖是标准的 `def` 函数而不是 `async def`，它将被运行在外部线程池中。

### 子依赖

你可以拥有多个相互依赖的依赖以及[子依赖](tutorial/dependencies/sub-dependencies.md){.internal-link target=_blank} （作为函数的参数），它们中的一些可能是通过 `async def` 声明，也可能是通过 `def` 声明。它们仍然可以正常工作，这些通过 `def` 声明的函数将会在外部线程中调用（来自线程池），而不是"被等待"。

### 其他函数

您可直接调用通过 `def` 或 `async def` 创建的任何其他函数，FastAPI 不会影响您调用它们的方式。

## Urgent Upgrade Notes
### (No, really, you MUST read this before you upgrade)
#### Cluster Lifecycle
- Kubeadm: add a new `kubelet-finalize` phase as part of the `init` workflow and an experimental sub-phase to enable automatic kubelet client certificate rotation on primary control-plane nodes.

// When the returned function is called it will wait.
func (d *dynamicSleeper) Timer(ctx context.Context) func() {
	t := time.Now()
	return func() {
		doneAt := time.Now()
		d.Sleep(ctx, doneAt.Sub(t))
	}
}

// Sleep sleeps the specified time multiplied by the sleep factor.
// If the factor is updated the sleep will be done again with the new factor.

	nanoTime, err := strconv.ParseInt(r.Header.Get("X-Minio-Time"), 10, 64)
	if err != nil {
		return errMalformedAuth
	}

	localTime := UTCNow()
	remoteTime := time.Unix(0, nanoTime)

	delta := remoteTime.Sub(localTime)
	if delta < 0 {
		delta *= -1
	}

	if delta > DefaultSkewTime {
		return errSkewedAuthTime
	}

	return nil
}

Um contêiner está rodando enquanto o **processo principal** (comando ou programa) estiver rodando.

Um contêiner normalmente tem um **único processo**, mas também é possível iniciar sub-processos a partir do processo principal, e dessa forma você terá **vários processos** no mesmo contêiner.

- Kubeadm: `kubeadm upgrade apply` now supports phase sub-command, user can use `kubeadm upgrade apply phase <phase-name>` to execute the specified phase, or use `kubeadm upgrade apply --skip-phases <phase-names>` to skip some phases during cluster upgrade.
