我可以在哪里从我的 cloudformation 模板附加弹性 IP 吗？

是否可以添加任何配置来将弹性 IP 附加到该实例将启动的实例。我知道我可以使用 cli 命令附加它，但我想通过我的 cloudformation 模板添加它。
最佳答案
当然。如 AWS::EC2::EIP 中所述:
Specifies an Elastic IP (EIP) address and can, optionally, associate it with an Amazon EC2 instance.
通过设置 InstanceId，您可以将 EIP 关联到 CloudFormation 的 EC2 实例。
对于您的情况，此代码片段应该可以解决问题:
"Resources": {
...,
"ElasticIP": {
"Type": "AWS::EC2::EIP",
"Properties": {
"InstanceId": {"Ref" : "StageInstance"}
}
}
}
