AWS-cloudformation“导入现有资源”出现错误

Question

我是 cloudformation 新手 - 我已使用 cloudformation 示例 yaml 文件手动创建了 EC2 实例 2 和另一个 EC2 实例 1。 我想使用“导入现有资源”选项添加手动创建的实例2。

但是我遇到了以下错误-

You have modified resources [MyInstance] in your template that are not being imported. Update, create or delete operations cannot be executed during import operations.

下面是yaml文件

Answer 1

您不能在导入其他资源的同时在 CFN 中创建/更新资源。你必须一件一件地做：

1. 从模板中删除

   EC2Instance2

   并部署

   EC2Instance

2. 添加

   EC2Instance

   并导入第二个实例。

Answer 2

如果您使用 SAML 或任何其他转换器，CloudFormation 不会让您导入新资源。 https://repost.aws/knowledge-center/cloudformation-template-resources-error
