Terraform S3 存储桶创建导致未授权

问题描述

创建 S3 存储桶需要什么 AWS 权限，这会导致 ec2/DescribeAccountAttributes 和 s3/CreateBucket 上的 HTTP/1.1 403 Forbidden.或者如何获取有关 AWS 方面的更多信息以进行进一步的故障排除.

What AWS permission is required to create a S3 bucket, which causes HTTP/1.1 403 Forbidden on ec2/DescribeAccountAttributes and s3/CreateBucket. Or how to get further information on AWS side to further trouble-shoot.

将 EC2 和 S3 的所有权限添加到用户帐户，但没有解决问题.

Added all permissions on EC2 and S3 to the user account, but did not solve the problem.

如果我拥有帐户所有者的所有权限(使用不同的帐户)，则不会发生这种情况.

If I have all the permission as the account owner (using different account), this will not happen.

正在尝试创建 S3 存储桶.

Trying to create a S3 bucket.

resource "aws_s3_bucket" "s3_bucket_tfstate" {
  bucket = "${var.s3_bucket_tfstate}"
  acl    = "private"
}

但是它会导致 403 和下面的 TF_LOG=DEBUG.

However it causes 403 with the TF_LOG=DEBUG below.

推荐答案

原因

通过 IAM 策略模拟器模拟 AWS S3 创建存储桶 发现阻止创建的策略是 MFA.

Cause

Simulated the AWS S3 create bucket via the IAM Policy simulator and found the policy preventing the creation was MFA.

session=$(aws sts get-session-token --profile $AWS_PROFILE --serial-number $SECURITY_DEVICE_ARN --token-code $MFA_TOKEN)
export AWS_ACCESS_KEY_ID=$(echo $session | jq  -r .Credentials.AccessKeyId)
export AWS_SECRET_ACCESS_KEY=$(echo $session | jq  -r .Credentials.SecretAccessKey)
export AWS_SESSION_TOKEN=$(echo $session | jq -r .Credentials.SessionToken)
export AWS_MFA_SERIAL_NUMBER=${MFA_TOKEN}

然后运行 ​​terraform.

Then run the terraform.
