Question

我正在尝试使用其他用户和自定义策略来执行我的Terraform计划命令，但我无法弄清楚我缺少哪些策略操作来运行此命令。我不想允许ec2:*。

资源已在运行，我们只是试图将代码移动到另一个项目。

当我使用ec2:*权限运行计划时，它正常运行。

错误：

Answer 1

aws_instance resource读取方法（刷新状态时调用）调用需要DescribeInstances的{{1}}，DescribeInstanceAttribute，DescribeIamInstanceProfileAssociations个端点，{{1}分别和ec2:DescribeInstances。

aws_ami data source调用需要ec2:DescribeInstanceAttribute IAM操作的ec2:DescribeIamInstanceProfileAssociations端点。

因此，您错过了DescribeImages（您有ec2:DescribeImages这不是有效的操作）和ec2:DescribeInstanceAttribute。

通过查看源代码（aws_instance和aws_ami）可以发现Terraform进行的调用，同时可以在AM docs for EC2中找到相关的IAM操作。

如果有充分理由不允许ec2:DescribeInstanceAttributes，我会感到惊讶，因为这些只是只读操作而且不应该暴露任何敏感信息。
