Using Toaster to Bake an Image

既然我们已经知道了如何在 Poky 中使用 BitBake 构建图像，那么接下来我们就来学习如何使用 Toaster 构建图像。我们将重点介绍 Toaster 最直接的使用方法，并介绍它的其他功能，让你了解它的能力。

Now that we know how to build an image using BitBake within Poky, we will learn how to do the same using Toaster. We are going to focus on the most straightforward usage of Toaster and also cover what else it can do so that you know about its capabilities.

1, What is Toaster?

Toaster 是一个用于配置和运行构建的网络界面。它与 BitBake 和 Poky 构建系统通信，以管理和收集有关构建、软件包和镜像的信息。

Toaster is a web interface to configure and run builds. It communicates with the BitBake and Poky build system to manage and gather information about the builds, packages, and images.

使用 Toaster 有两种方法：

* 本地使用： 我们可以将 Toaster 作为本地实例运行，适合单用户开发，提供 BitBake 命令行的图形界面和一些构建信息。

* 托管： 适合多用户使用。Toaster 服务器会构建和存储用户的工件。使用托管实例时，其组件可分布在多台机器上。

There are two ways to use Toaster:

* Locally: We can run Toaster as a local instance, suitable for single-user development, providing a graphical interface to the BitBake command lines and some build information.

* Hosted: This is suitable for multiple users. The Toaster servers build and store the users’ artifacts. Its components can be spread across several machines when using a hosted instance.

在本章中，我们将把 Toaster 作为本地实例使用。不过，如果你想将其用作托管实例，请访问以下网站获取说明 - Toaster Manual (Toaster User Manual — The Yocto Project ® 4.0.4 documentation)。

In this chapter, we will use Toaster as a local instance. However, if you want to use i
