Azure DevOps AWS CloudFormation Create/Update 堆栈任务 - 失败 'stack does not exist'

Question

我有一个配置为使用 AWS CloudFormation Create/Update Stack 任务的发布管道。该任务配置为使用如下更改集：

然而，由于某种原因，管道一直在失败。它失败是因为它测试堆栈的存在，发现它不存在，切换到 'create' 模式，但随后测试是否存在变更集，并且因为变更集也不存在而失败？？这毫无意义。

Answer 1

您可以按照以下步骤解决问题：

首先检查用于创建AWS Credentials服务连接的AWS账户是否有cloudformation:DescribeStacks和cloudformation:DescribeStackEvents permissions。如果您使用 IAM 角色创建 AWS Credentials 服务连接。您需要确保将上述权限分配给该角色。参见 here。

确保你 select 正确 AWS Region。 CloudFormation 是区域特定的。

手动删除存在的堆栈，或使用 AWS CloudFormation 删除堆栈在创建之前删除堆栈的任务。请参阅以下线程以获取信息。

Stack does not exist" while creating a new stack

Stack with id does not exist

Answer 2

事实证明这是 YAML 模板本身的多个小语法错误，例如 Ref 参数的使用方式。不幸的是，错误消息并不能真正帮助发现问题，另外 SAM CLI 验证命令确认模板有效。

尽管如此，现在有了固定且有效的无服务器 YAML 模板，管道仍在运行。
