堆栈创建挂在 CREATE_IN_PROGRESS答案

【问题标题】：Stack creation is hanging on CREATE_IN_PROGRESS堆栈创建挂在 CREATE_IN_PROGRESS

【问题描述】：

我一直在尝试使用 lambda 支持的自定义资源。我正在尝试使用自定义资源触发 Lambda 函数。在创建堆栈时，自定义资源挂在 CREATE_IN_PROGRESS 上，但我能够收到电子邮件，并且在尝试删除堆栈时，它卡在 DELETE_IN_PROGRESS 上。

现在我有五个堆栈挂在 DELETE_IN_PROGRESS 上。自定义资源在哪里创建？

【解决方案1】：

您的模板已挂起，因为 lambda 未正确执行对 cloudformation 的回调。

在您的 SES 回调中，您首先从不发送回调以防出错，但除此之外，您首先使用“context.succeed(event);”终止 Lambda然后调用“response.send(event, context, response.SUCCESS);”。

为了正确实现，您只需要调用 response.send 函数。在该函数中，callback.succeed 将被调用。

您可以使用本网站上的示例作为参考。 aws lambda for cloudformation
