尝试在 Terraform 中使用 COS HMAC 凭据时此值没有任何属性错误？

Question

我正在尝试在 Terraform 中为云对象 Storage/S3 使用 HMAC 凭据，但看到此错误。

Error: Unsupported attribute

  on main.tf line 56, in resource "ibm_cos_bucket" "sink_bucket":
  56:       ACCESS_KEY               = ibm_resource_key.cos_key.credentials.cos_hmac_keys.access_key_id

This value does not have any attributes.


Error: Unsupported attribute

  on main.tf line 57, in resource "ibm_cos_bucket" "sink_bucket":
  57:       SECRET_ACCESS_KEY        = ibm_resource_key.cos_key.credentials.cos_hmac_keys.secret_access_key

This value does not have any attributes.

我在创建 cos_key

时通过设置 HMAC=true 生成了 COS HMAC 凭据

resource ibm_resource_key cos_key {
  name                 = "${var.basename}-cos-key"
  resource_instance_id = ibm_resource_instance.cos.id
  role                 = "Writer"

  parameters = {
    service-endpoints = "private"
    HMAC = true
  }
}

当我检查 terraform.tstate 文件时，我看到如下凭据

"cos_key": {
      "value": {
        "credentials": {
          "apikey": "muydB9TyqWr9_aCmFlSRSu-JG3J3PPzXcxxxxxxx",
          "cos_hmac_keys.access_key_id": "e0892b46cfe1411cxxxxxx0",
          "cos_hmac_keys.secret_access_key": "8520aca8680e3e930f74a8869xxxxxx8a27a6",
          ...
          }
        }
      }

这对我有用

provisioner "local-exec" {
    command = "echo 'Credentials for MINIO client...'"
    environment = {
      ACCESS_KEY               = ibm_resource_key.cos_key.credentials["cos_hmac_keys.access_key_id"]
      SECRET_ACCESS_KEY        = ibm_resource_key.cos_key.credentials["cos_hmac_keys.secret_access_key"]
      COS_REGION               = var.region
      COS_BUCKET_NAME          = ibm_cos_bucket.sink_bucket.bucket_name
    }
  }

这里的问题是自定义 json 属性，其中包含 cos_hmac_keys.access_key_id 之类的点 (.)。在您使用以下符号

之前，Terraform 会抛出错误

credentials["cos_hmac_keys.access_key_id"]
