maas安裝windows鏡像

來自專欄 MAAS

maas使用python3作為後端語言，twisted提供service服務，django為web服務。

使用curtin作為系統鏡像安裝中樞。

curtin ubuntu維護項目：http://curtin.readthedocs.io/en/latest/topics/overview.html

官網：https://launchpad.net/curtin

curtin 設計成主要為裸機安裝系統， 目標就是從特地服務下載數據，並將數據寫進磁碟，快速boot。

curtin步驟：

1：安裝boot環境

2：早期命令

3：partitioning 劃分

4：網路發現和安裝

5：從來源獲取數據

6：hook for installed OS to customize ifself

7：最終命令

我們查看一下maas下的curtin腳本。

安裝windows，目標便是，讓curtin識別到windows，並hook到widows相關os信息。
