如果在你的用例中，**并行多次**运行这些前置步骤没有问题（例如你不是在跑数据库迁移，而只是检查数据库是否就绪），那么你也可以把这些步骤放在每个容器中，在启动主进程之前执行。

### 单个容器 { #single-container }

如果你的架构较为简单，使用一个**单个容器**，其后再启动多个**worker 进程**（或者也只有一个进程），那么你可以在同一个容器中，在启动应用进程之前执行这些前置步骤。

### 基础 Docker 镜像 { #base-docker-image }

曾经有一个官方的 FastAPI Docker 镜像：[tiangolo/uvicorn-gunicorn-fastapi](https://github.com/tiangolo/uvicorn-gunicorn-fastapi-docker)。但它现在已被弃用。⛔️

你大概率**不应该**使用这个基础镜像（或任何其它类似的镜像）。

### Breaking Changes - Upgrade

This release adds support for [Trio](https://trio.readthedocs.io/en/stable/). ✨

It upgrades the version of Starlette to `0.15.0`, now based on [AnyIO](https://anyio.readthedocs.io/en/stable/), and the internal async components in **FastAPI** are now based on AnyIO as well, making it compatible with both **asyncio** and **Trio**.

// xlMetaV2Version describes the journal entry, Type defines
// the current journal entry type other types might be nil based
// on what Type field carries, it is imperative for the caller
// to verify which journal type first before accessing rest of the fields.
type xlMetaV2Version struct {

	type _Ctype_void [0]byte

The _cgo_gotypes.go file also contains the definitions of the
functions. They all have similar bodies that invoke runtime·cgocall
to make a switch from the Go runtime world to the system C (GCC-based)
world.

For example, here is the definition of _Cfunc_puts:

	//go:cgo_import_static _cgo_be59f0f25121_Cfunc_puts
	//go:linkname __cgofn__cgo_be59f0f25121_Cfunc_puts _cgo_be59f0f25121_Cfunc_puts

- Fixed a bug in kube-proxy nftables mode (GA as of 1.33) that fails to determine if traffic originates from a local source on the node. The issue was caused by using the wrong meta `iif` instead of `iifname` for name based matches. ([#134117](https://github.com/kubernetes/kubernetes/pull/134117),...

                It's not required to specify all the tags used.

                The tags that are not declared MAY be organized randomly or based
                on the tools' logic. Each tag name in the list MUST be unique.

                The value of each item is a `dict` containing:

                * `name`: The name of the tag.
