Terraform-每次申请时将文件上传到S3 [英] Terraform - Upload file to S3 on every apply

问题描述

我需要将文件夹上传到S3存储桶.但是当我第一次申请时.它只是上传.但是我这里有两个问题:

I need to upload a folder to S3 Bucket. But when I apply for the first time. It just uploads. But I have two problems here:

1. 上载的版本输出为null.我希望有一些version_id，例如1、2、3
2. 再次运行terraform apply时，显示Apply complete! Resources: 0 added, 0 changed, 0 destroyed.我希望在运行terraform apply并创建新版本时始终上传所有文件.

1. uploaded version outputs as null. I would expect some version_id like 1, 2, 3
2. When running terraform apply again, it says Apply complete! Resources: 0 added, 0 changed, 0 destroyed. I would expect to upload all the times when I run terraform apply and create a new version.

我做错了什么?这是我的Terraform配置:

What am I doing wrong? Here is my Terraform config:

resource "aws_s3_bucket" "my_bucket" {
  bucket = "my_bucket_name"

  versioning {
    enabled = true
  }
}

resource "aws_s3_bucket_object" "file_upload" {
  bucket = "my_bucket"
  key    = "my_bucket_key"
  source = "my_files.zip"
}

output "my_bucket_file_version" {
  value = "${aws_s3_bucket_object.file_upload.version_id}"
}

推荐答案

Terraform仅在检测到配置和远程对象属性之间的差异时才对远程对象进行更改.到目前为止，在配置中，配置仅包含文件名.它不包含任何有关文件内容的内容，因此Terraform无法对文件更改做出反应.

Terraform only makes changes to the remote objects when it detects a difference between the configuration and the remote object attributes. In the configuration as you've written it so far, the configuration includes only the filename. It includes nothing about the content of the file, so Terraform can't react to the file changing.

要进行后续更改，有几个选项:

To make subsequent changes, there are a few options:

• 您可以为每个新版本使用不同的本地文件名.
• 您可以为每个新版本使用不同的远程对象路径.
• 无论本地文件名或对象路径如何，都可以使用对象etag使Terraform识别内容何时更改.

在这种情况下，这些决赛看起来似乎最接近您想要的.为此，添加etag参数并将其设置为文件的MD5哈希值:

The final of these seems closest to what you want in this case. To do that, add the etag argument and set it to be an MD5 hash of the file:

resource "aws_s3_bucket_object" "file_upload" {
  bucket = "my_bucket"
  key    = "my_bucket_key"
  source = "${path.module}/my_files.zip"
  etag   = "${filemd5("${path.module}/my_files.zip")}"
}

有了该额外的参数，Terraform将检测磁盘上文件的MD5哈希何时与S3中远程存储的哈希不同，并计划相应地更新对象.

With that extra argument in place, Terraform will detect when the MD5 hash of the file on disk is different than that stored remotely in S3 and will plan to update the object accordingly.

(我不确定version_id怎么回事.只要在存储桶上启用了版本控制，它就应该起作用.)

(I'm not sure what's going on with version_id. It should work as long as versioning is enabled on the bucket.)
