amazon-s3 - 在本地使用 terraform 从 S3 下载文件

Question

我正在尝试将文件从 s3 存储桶下载到我运行 terraform 的服务器，这可能吗？我试过下面的代码

data "aws_s3_bucket_objects" "my_objects" {
  bucket = "examplebucket"
}

data "aws_s3_bucket_object" "object_info" {
  key    = "${element(data.aws_s3_bucket_objects.my_objects.keys, count.index)}"
  bucket = "${data.aws_s3_bucket_objects.my_objects.bucket}"

}
provisioner "local-exec" {
    content = "${data.aws_s3_bucket_object.object_info.body}"
 }

当我运行 terraform plan 时出现以下错误

Error: Unsupported block type

  on s3.tf line 11:
  11: provisioner "local-exec" {

Blocks of type "provisioner" are not expected here.

我在这里遗漏了什么吗？如有任何帮助，我们将不胜感激。

只需使用本地 provider

data "aws_s3_bucket_objects" "my_objects" {
  bucket = "examplebucket"
  //prefix = "your_prefix"
}    

data "aws_s3_bucket_object" "object_info" {
  count  = "${length(data.aws_s3_bucket_objects.my_objects.keys)}"
  key    = "${element(data.aws_s3_bucket_objects.my_objects.keys, count.index)}"
  bucket = "${data.aws_s3_bucket_objects.my_objects.bucket}"

}

resource "local_file" "foo" {
    count    = "${length(data.aws_s3_bucket_objects.my_objects.keys)}"
    content  = "${data.aws_s3_bucket_object.object_info[count.index].body}"
    filename = "/path/to/file-${count.index}"
}

PS:确保你的对象有一个 human-readable Content-Type , body 字段仅适用于此类对象。
