所以我有一个AWS CloudFormation模板，包含3个不同的实例'类型'（服务器，代理，中继）
我正在使用AutoScaling动态启动X类型的实例。
我的问题是我需要从模板的输出中获取这些服务器的所有IP，最好分成几个部分。
即
服务器：x.x.x.x y.y.y.y
继电器：z.z.z.z。
代理人：a.a.a.a
如何从输出中获取实例ID？ （我可以从ID中获取IP）

不，你不能将输出设置为ips。云形成负责自动调节组和自动调节启动配置，但它无法控制各个EC2实例，因此您无法从它们获取信息到输出中。
您可以在启动时编写在EC2实例上运行的内容，以使用ip值在堆栈上设置标记。但是当实例终止时，这可能很难维护。
在bash上并使用AWS CLI实用程序，您可以执行以下操作：
#!/bin/bash
AUTOSCALING_GROUP="mygroup"
aws ec2 describe-instances --filters \
"Name=tag:aws:autoscaling:groupName,Values=$AUTOSCALING_GROUP" \
"Name=instance-state-name,Values=running" | \
grep -o '\"i-[0-9a-f]\\+\"' | grep -o '[^\"]\\+'
这将输出'mygroup'自动缩放组中所有计算机的实例ID，每行一个。
