当我在 .terraform/modules/main.tf
和 variables.tf
文件中修复它们时,计划成功并且当我从 CLI 触发时它通过了。但是,当我从 UI 触发计划时实际推送代码时,它不起作用。
所以,当我做terraform init --upgrade
时。它恢复正常,我可以看到同样的问题。
你能帮我解决这个问题吗?谢谢!
【问题讨论】:
您的问题缺乏细节。你具体改了什么?计划是什么?更改前的原始文件是什么? 我已经更新了这个问题,你能检查一下吗?谢谢! 【参考方案1】:.terraform/modules/ec2-datapipeline/main.tf
中的内容实际上是来自名为“ec2-datapipeline”的外部模块的 main.tf 文件,该模块在您自己的代码中某处引用(查找 module "ec2-datapipeline"
)。
您必须修复“ec2-datapipeline”源中的错误,提交并标记它,然后在您自己的代码中更新源引用。
您的更改在重新初始化时消失的原因是,您通过了 --upgrade
开关,该开关告诉 Terraform 重新下载外部模块源,即使它们在本地缓存在 .terraform/modules
缓存中。
