如何在Terraform中将DynamoDB IAM角色添加到EKS工作节点？

Question

我正在尝试从EKS中的工作程序节点写入DynamoDB。我当前正在附加一个IAM角色策略，该策略授予对DynamoDB的完全访问权限。这是解决此问题的正确方法吗？我的应用程序的请求当前处于挂起状态，我认为这与我的节点没有正确的权限有关。

这是我当前在Terraform中的设置

resource "aws_iam_role" "worker-node" {
  name = "worker-node"

  assume_role_policy = <<POLICY

      "Principal": {
        "Service": "ec2.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
POLICY
}

  policy_arn = "arn:aws:iam::aws:policy/AmazonEKSWorkerNodePolicy"
  role       = aws_iam_role.worker-node.name
}

  node_group_name = "node-group-private"

  subnet_ids      = [aws_subnet.private-1.id, aws_subnet.private-2.id]
  instance_types = ["t2.micro"]

  scaling_config {
    desired_size = 3
    max_size     = 3
    min_size     = 1
  }

  depends_on = [
    aws_iam_role_policy_attachment.worker-node-AmazonEKSWorkerNodePolicy,
