在EC2实例上执行AWS Lambda run命令并获取结果 [英] AWS Lambda run command on EC2 instance and get result

问题描述

我有一个正在运行一些进程的EC2实例。我也有通过各种方式触发的Lambda脚本。我希望这个Lambda脚本与我的EC2实例进行对话，并从中获取正在运行的进程的列表（基本上在EC2框中运行 ps aux 并读取输出）。

I have an EC2 instance that is running a few processes. I also have a Lambda script that is triggered through various means. I would like this Lambda script to talk to my EC2 instance and get a list of running processes from it (Essentially run ps aux on the EC2 box, and read the output).

现在，只需一个实例及其实例ID，这已经很容易了。只需SSH进入，运行命令，获取输出，就可以了。但是，我想将此扩展到多个EC2实例，对于这些实例，只有instance-id是已知的，并且可能无法提供SSH密钥。

Now this is easy enough with just one instance and its instance-id. Just SSH in, run the command, get the output, and be on my way. However, I would like to scale this to multiple EC2 instances, for which only the instance-id is known and SSH keys may not be given.

Lambda和Boto（或其他库）是否可以进行这种配置？还是只需要在每个实例上运行一个微型服务器，该微型服务器就会使用给定的信息进行回复（我确实在尝试避免这种情况）

Is such a configuration possible with Lambda and Boto (or other libraries)? Or do I just have to run a microserver on each of my instances that will reply with the given information (something I'm really trying to avoid)

推荐答案

您可以通过 AWS系统管理器-运行命令

AWS Systems Manager可为您的实例提供安全，可靠的远程管理，而无需登录服务器，而无需使用堡垒主机，SSH或远程PowerShell。

AWS Systems Manager provides you safe, secure remote management of your instances at scale without logging into your servers, replacing the need for bastion hosts, SSH, or remote PowerShell.

具体是：

• 使用Lambda函数中的send-command API获取一组实例上所有进程的列表。您可以通过提供实例列表甚至标签查询来做到这一点


• 您还可以使用CloudWatch Events直接触发运行命令
