如何为 Terraform 配置 AWS MFA？

Question

我想为 Terraform 执行 MFA，因此期望从我的虚拟 MFA 设备中为每个terraform [command]. 阅读文档后： cli-roles terraform mfa 我创建了一个角色：

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::[ACCOUNT_ID]:user/testuser"
      },
      "Action": "sts:AssumeRole",
      "Condition": {
        "Bool": {
          "aws:MultiFactorAuthPresent": "true"
        }
      }
    }
  ]
}

该用户默认强制使用 MFA，我为他配置了虚拟 MFA 设备。

~/.aws/凭证：

[default]
...

[terraform_role]
role_arn = arn:aws:iam::[ACCOUNT_ID]:role/terraform-test-role
source_profile = default
mfa_serial = arn:aws:iam::[ACCOUNT_ID]:mfa/testuser

在我的 Terraform 环境中，我放置了以下内容：

provider "aws" {
  profile = "terraform_role"
}

但是当我运行terraform plan它时会抛出一个错误：

Error refreshing state: 1 error(s) occurred:

* provider.aws: No valid credential sources found for AWS Provider.
  Please see https://terraform.io/docs/providers/aws/index.html for more information on
  providing credentials for the AWS Provider

解决办法是指定一条assume_role语句：

provider "aws" {
  profile = "default"
  assume_role {
    role_arn = "arn:aws:iam::[ACCOUNT_ID]:role/terraform-test-role"
  }
}
