Question

cloud-init用户数据对象的cloud-config部分中的指令顺序是什么。这对于避免种族类型的情况很重要。

我知道bootcmd在runcmd之前提前运行，但有没有一个很好的所有方法顺序列表？

此外：

有配置合并“订单如下： - cli配置文件覆盖环境配置文件它覆盖覆盖数据源的实例配置覆盖覆盖覆盖的基本配置的配置默认配置。“（参见更改日志）

在单个生成的脚本目录中，脚本按照python“sorted（）”builtin

给出的顺序运行

注意：虽然这在回答时是正确的，但查看上面提到的存储库（截至2017年9月），现在有一个cloud.cfg.tmpl模板文件，其中不同发行版的设置略有不同
