Terraform：设置从AWS LoadBalancer到S3 bucket的日志记录

我有一个aws_lb，我想登录到S3存储桶

我尝试过但没有成功的事情：

data "aws_elb_service_account" "main" {}

data "aws_iam_policy_document" "bucket_policy" {
  statement {
    sid       = ""
    actions   = ["s3:PutObject"]
    resources = ["arn:aws:s3:::my-bucket/*"]

    principals {
      type        = "AWS"
      identifiers = ["${data.aws_elb_service_account.main.arn}"]
    }
  }
}

我也试过：

resource "aws_iam_role" "lb-logs-role" {
  name = "lb-logs-role"

  assume_role_policy = <<EOF
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Action": "sts:AssumeRole",
      "Principal": {
        "Service": "elasticloadbalancing.amazonaws.com"
      },
      "Effect": "Allow",
      "Sid": ""
    }
  ]
}
EOF

  tags = {
    Name = "lb-logs-role"
    Environment  = terraform.workspace
    Management   = "Managed by Terraform"
  }
}

resource "aws_iam_role_policy" "s3-logs-access" {
  name = "s3-logs-access"
  role = aws_iam_role.lb-logs-role.id

  policy = <<EOF
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Action": [
        "s3:PutObject"
      ],
      "Effect": "Allow",
      "Resource": "arn:aws:s3:::my-bucket/*"
    }
  ]
}
EOF
}

有什么想法吗？

问题似乎出在您的策略上，但您可以使用aws_lb尝试我的代码，以下是在默认VPC中启动lb并创建名为

test-bucket-1-unique-name

的bucket、名为

test http lb

的策略和lb的完整配置。以及已注释的SG和Route53条目
