如何从AutoScaling获取所有EC2实例ID？ [英] How to obtain all EC2 instance IDs from AutoScaling?
问题描述
因此，我有一个带有3种不同实例类型（服务器，代理，中继）的AWS CloudFormation模板
So I have an AWS CloudFormation template with 3 different instance 'types' (Server, Agent, Relay)
我正在使用AutoScaling动态启动X个类型的实例。
I'm using AutoScaling to dynamically launch X number of instances of a type.
我的问题是我需要模板输出中所有这些服务器的IP，最好将其分类。
My problem is that I need all of the IPs of these servers from Outputs of the template, preferably sorted into sections.
ie
服务器：
xxxx
yyyy
Servers: x.x.x.x y.y.y.y
中继：
zzzz
Relays: z.z.z.z
代理商：
aaaaa
Agents: a.a.a.a
如何仅从中获取实例ID输出？ （我可以从ID中获取IP）
How do I get just the instance Ids from the Outputs? (I can get the IPs from the IDs)
附加模板：

推荐答案
不，您不能将输出设置为ips。云的形成负责自动伸缩组和自动伸缩启动配置，但它无法控制单个EC2实例，因此您无法从它们获取信息到输出中。
No you can't set the outputs to be the ips. The cloud formation is responsible for the autoscaling groups and the autoscaling launch configuration but it does not have control of the individual EC2 instances, so you cannot get information from them into the outputs.
您可以编写一些在启动时在EC2实例上运行的内容，以使用ip值在堆栈上设置标签。但这在实例终止时可能很难维护。
You could write something that runs on the EC2 instances at startup to set a tag on the stack with the ip values. But this could get difficult to maintain when instances terminate.
