如何列出我的 EC2 实例并获取其私有 IP
我开始将 EC2 与大量 SPOT 实例（> 100）一起使用，我试图找到一种方法来检索所有 IC2 实例的私有 IP，以便稍后使用它们来部署二进制文件等。
有人可以帮我做吗？
提前致谢。
I'm starting to use EC2 with a lot of SPOT instances (>100), I'm trying to find a way to retrieve all my IC2 instances private ip's in order to use them later to deploy binaries and so on.
Can anyone help me to do it?
Thanks in advance.

由于您没有列出框架或语言：
Since you didn't list a framework or language:
Amazon 将根据您的竞价实例请求参数启动和停止竞价实例，而无需您参与。因此，您在时间 A 查询的竞价实例 IP 地址列表在时间 B 可能不准确。
问题 1：您认为 IP 地址 A 是您的竞价实例之一，但在此期间 Amazon 终止了您的竞价实例，并且使用相同的私有 IP 地址启动其他人的实例。在向您所联系的实例传递任何敏感信息或信任它为您提供的任何答案之前，您需要确保所联系的实例确实属于您。
问题2：在您收到查询结果后，亚马逊已经根据现货价格为您启动了新的现货实例。当您转到“部署二进制文件等”时，您可能会错过一些实例，从而使它们处于不稳定或过时的状态。
您可能会考虑让竞价实例在启动时（也许定期）自行配置和更新。
Amazon will start and stop spot instances without your involvement but based on your spot instance request parameters. Because of this, the list of spot instance IP addresses you query at time A might not be accurate at time B.
Problem 1: You think IP address A is one of your spot instances, but in the interim Amazon has terminated your spot instance and started somebody else's instance using the same private IP address. You'll want to make sure that an instance you are contacting is really yours before you pass it anything sensitive or trust any answers it gives you.
Problem 2: In the time since you got the query results, Amazon has started new spot instances for you based on the spot price. When you go to "deploy binaries and so on" you could miss some of the instances leaving them in unstable or out-of-date states.
You might consider having the spot instances configure and update themselves when they start up, and perhaps on regular intervals.
