Azure ARM - 自定义脚本扩展 - 随机失败
Azure ARM - Custom Script Extension - Failing randomly
我开发了一个 Azure ARM 模板来部署 Ubuntu Linux 机器，一旦配置 bash 脚本将 运行 安装特定软件。该软件涉及下载一些软件包以及传递来自用户的输入参数以完成配置。我面临的问题是脚本扩展似乎间歇性地工作。我部署成功一次，现在一直失败。这是自定义脚本开始执行几秒钟后 returns 的错误：

有人知道如何防止此问题或实施任何可能需要的更正吗？
好吧，这清楚地表明：脚本以代码 1 退出。这意味着脚本本身失败了。所以你需要登录到虚拟机并查看 c:\windowsazure\packages\logs（或类似的东西）的扩展日志，找出问题所在并用一些 try\catch 逻辑包装它。另外，考虑将错误传播到控制台，这样您就可以在日志中实际看到它们。
我终于弄明白是怎么回事了。软件安装具有未自动安装的依赖项，它使整个脚本失败并以状态 = 1 退出。我更改了 bash 脚本，并在安装过程中手动添加了推荐的依赖项，以及 re-deployed 模板和 booom。安装很顺利。
这是生成的错误消息：
