amazon-web-services - Terraform 配置 LB 属性失败

Question

我遵循了 this 上的第一个答案在 StackOverflow 上发帖，但我收到此错误:

Failure configuring LB attributes: InvalidConfigurationRequest: Access Denied for bucket: myproject-log. Please check S3bucket permission status code: 400

这是我的代码:

s3_bucket

data "aws_elb_service_account" "main" {}

resource "aws_s3_bucket" "bucket_log" {
  bucket = "${var.project}-log"
  acl    = "log-delivery-write"

policy = <<POLICY
{
  "Id": "Policy",
  "Version": "2012-10-17",
  "Statement": [
    {
      "Action": [
        "s3:PutObject"
      ],
      "Effect": "Allow",
      "Resource": "arn:aws:s3:::${var.project}-log/AWSLogs/*",
      "Principal": {
        "AWS": [
          "${data.aws_elb_service_account.main.arn}"
        ]
      }
    }
  ]
}
POLICY

}

负载均衡器

resource "aws_lb" "vm_stage" {
  name = "${var.project}-lb-stg"
  internal           = false
  load_balancer_type = "application"
  subnets         = [aws_subnet.subnet_1.id, aws_subnet.subnet_2.id, aws_subnet.subnet_3.id]
  security_groups = [aws_security_group.elb_project_stg.id]
  access_logs {
    bucket  = aws_s3_bucket.bucket_log.id
    prefix  = "lb-stg"
    enabled = true
  }
  tags = {
    Name = "${var.project}-lb-stg"
  }
}

官方 AWS 文档
https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/enable-access-logs.html
解决方案
引用上面的文档并更改存储桶的 iam 策略以反射(reflect)文档说明的内容。日志记录实际上是由 AWS 完成的，而不是您的角色或 IAM 用户。因此，您需要授予 ÅWS 权限才能执行此操作。这就是为什么文档在策略中显示指定 delivery.logs.amazonaws.com 的声明的原因。主要的。该委托(delegate)人是 AWS 日志记录服务。即使您的存储桶托管在 AWS 上，默认情况下他们也不会授予自己访问您的存储桶的权限。如果您希望他们的服务正常工作，您必须明确授予对 AWS 的访问权限。
