如何在 terraform 0.14 中选择正确的 docker 提供程序

Question

为了与 Docker 集成，我将 terraform 设置如下：

所需的提供者：

 docker = {
      source = "kreuzwerker/docker"
      version = "2.11.0"
    }

该提供者的实例化：

provider "docker" {
}

最后我在 resource 中按如下方式使用它：

data "docker_registry_image" "myapp" {
  name = some_image_url
}

当我运行terraform init 时，它似乎仍然指的是 HashiCorp 的“旧”terraform 提供程序：

Partner and community providers are signed by their developers.

Error: Failed to query available provider packages

Could not retrieve the list of available versions for provider
hashicorp/docker: provider registry registry.terraform.io does not have a
provider named registry.terraform.io/hashicorp/docker

If you have just upgraded directly from Terraform v0.12 to Terraform v0.14
then please upgrade to Terraform v0.13 first and follow the upgrade guide for
that release, which might help you address this problem.

Did you intend to use kreuzwerker/docker? If so, you must specify that source
address in each module which requires that provider. To see which modules are
currently depending on hashicorp/docker, run the following command:
    terraform providers

当我运行terraform providers 时，我确实看到了由docker_registry_image 引起的参考：

...
        ├── provider[registry.terraform.io/hashicorp/docker]
...

注意事项：

• 所有其他供应商都使用最新版本。
• 我使用的是 terraform 0.14.6。
• 上面给出的资源是我正在使用的唯一的 docker 资源。
• 我已经尝试在提供者和资源上使用别名，但它不起作用。

我该如何解决这个问题？谢谢！

Answer 1

我们好像没有正确迁移。

我已经通过将我的恐怖版本设置回0.13 并运行terraform 0.13upgrade 解决了这个问题。命令执行后，我再次升级到0.14.6，一切正常。

命令做了什么？

这在我的模块文件夹中创建了一个名为versions.tf 的文件（我在其中使用 docker 资源），其内容如下：

terraform {
  required_providers {
    docker = {
      source = "kreuzwerker/docker"
    }
    google = {
      source = "hashicorp/google"
    }
    random = {
      source = "hashicorp/random"
    }
  }
  required_version = ">= 0.13"
}

请注意，此处创建的内容取决于您的具体情况。

它还在我的工作目录中创建了一个文件，其中包含：

terraform {
  required_version = ">= 0.13"
}

（提供程序在不同的文件中，并且已经有正确的 docker 源，因此只将所需的版本添加到新文件中。）
