所以我正在尝试创建一个aws lambda函数,登录实例并做一些事情.并且该脚本在lambda之外工作正常,但是当我使用与此https://aws.amazon.com/blogs/compute/scheduling-ssh-jobs-using-aws-lambda/相同的说明打包它时,它不会工作.它抛出了这个错误.

我在 k8s 文档中找不到这个，我只是想知道 k8s 在每个容器中创建的默认环境变量是什么。不是用户创建的默认值，而是喜欢（这只是一个例子）可能类似{service_name}_PORT或类似的东西。我只想知道默认情况下容器中可用的信息。

我有一个启动脚本（用户数据），该脚本在具有ubuntu 16.04映像的aws中启动时运行，而我遇到的问题是，当它到达运行ansible剧本的那一部分时，该剧本会失败，并显示此基本错误消息Could not get lock /var/lib/dpkg/lock。现在，当我登录并尝试手动运行ansible脚本时，它可以工作，但是如果我从aws用户数据中运行它，它将失败并显示错误。

这是完整的错误

重命名监视程序中正在监视的文件会生成on_moved事件触发器.我遇到的问题是没有办法告诉文件被移动/重命名的内容(因为重命名文件时也会发生on_moved事件触发器).有什么方法可以将它构建到看门狗中,还是应该在我正在编写的程序中构建一个变通方法？

这是一些示例代码
