所以我有一个 AWS CloudFormation 模板，其中包含 3 种不同的实例“类型”(服务器、代理、中继)
我正在使用 AutoScaling 动态启动 X 个类型的实例。
我的问题是我需要来自模板输出的这些服务器的所有 IP，最好按部分分类。
IE。
服务器:
xxx
y.y.y.y
继电器:
z.z.z.z
代理商:
a.a.a.a
如何仅从输出中获取实例 ID？ (我可以从 ID 中获取 IP)

最佳答案
不，您不能将输出设置为 ips。云形成负责自动扩展组和自动扩展启动配置，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。
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。但是当实例终止时，这可能很难维护。
