如何在Terraform中使用多提供商版本？

Question

只是想知道是否可以使用多个提供商版本？ 例如，当使用Terraform Azure提供商部署资源时 资源的一部分是由Azurerm提供商版本2.55.0部署的，其REST与提供商版本2.99.0一起部署

吗？我尝试了下面的代码，但没有工作，

terraform {
  required_version = ">= 0.12.29, < 2.0"
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = ">=2.99.0"
      #     version = "~> 2.64"

    }

     azurermlatest = {
       source  = "hashicorp/azurerm"
       version = "= 3.3.0"
    }

  }
}

│ Error: Failed to query available provider packages
│
│ Could not retrieve the list of available versions for provider hashicorp/azurermlatest: provider registry registry.terraform.io
│ does not have a provider named registry.terraform.io/hashicorp/azurermlatest
│
│ All modules should specify their required_providers so that external consumers will get the correct providers when using a module.
│ To see which modules are currently depending on hashicorp/azurermlatest, run the following command:
│     terraform providers

我知道Terraform将使用符合配置版本约束的最新版本的限制。但是在最新文档中，该语句已被删除，因此不确定现在是否有多个版本提供商

更新：

清理缓存和后端后，错误消失了 但是多提供者仍然不起作用，代码和错误如下 有人会检查并提供帮助吗？

    }

      source  = "hashicorp/azurerm"

似乎Terraform仍在使用提供商3.3.0，即使我将提供商设置为azurerm.old

Answer 1

我已经尝试了您的代码，并且您的提供商块似乎已正确设置。

重现错误的唯一方法是是否已更新源以引用无效的路径：

terraform {
  required_version = "= 1.1.3"
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = ">=2.99.0"
    }
    azurermlatest = {
       source  = "hashicorp/azurermlatest"
       version = "= 3.3.0"
    }
  }
}

因此，错误肯定来自其他地方。我建议您查看您的代码，也许清理缓存或 .terraform 文件夹以及任何其他临时文件，然后重新运行 Terraform Init 和 plan 再次。

参见此页面提供者最佳实践。

Answer 2

您提供的整个概念和答案是完全错误的。
提供程序示例中的阻止仅是因为两个约束：

• ＆gt; = 2.99.0
• = 3.3.0

实际上等于<<<<代码> = 3.3.0 和Terraform正在下载它。

用 quired_providers block命名同一提供商并不是一个好练习，实际上，Terraform会在使用 Terraform Init 时提醒您

：以前需要“ Azurerm”的本地名称“ Azurermlatest”。

如果您要执行不允许Terraform下载版本高于2.x的约束（如您所注释的那样），则会看到：

“无法检索提供者Hashicorp/azurerm的可用版本列表：否可用的发行版匹配给定约束2.99.0，3.3.0“

从理论上讲，您可以将 azure 提供商复制到内部的私人注册表，重命名并在每个资源名称中使用其名称，但这听起来很恐怖和错。

更好的想法是将项目分为两个，并使用较旧的提供商版本运行“旧版”代码，以及带有新的提供商版本的新代码。您可以使用 remote_state 对象组合这两个项目（）。
