错误:当将资源解压缩到模块中时，依赖项锁定文件不一致

Question

我对terraform很陌生，当我将其中一个资源提取到一个模块中时，我得到了以下内容：

Error: Inconsistent dependency lock file
│
│ The following dependency selections recorded in the lock file are inconsistent with the current
│ configuration:
│   - provider registry.terraform.io/hashicorp/heroku: required by this configuration but no version is selected
│
│ To update the locked dependency selections to match a changed configuration, run:
│   terraform init -upgrade

我做得怎么样？

首先我有这样的想法：

provider "heroku" {}

resource "heroku_app" "example" {
  name   = "learn-terraform-heroku-ob"
  region = "us"
}

resource "heroku_addon" "redis" {
  app  = heroku_app.example.id
  plan = "rediscloud:30"
}

在此之后，terraform init没有错误地运行，terraform plan也成功了。

然后，我将redis资源声明提取到一个模块中：

provider "heroku" {}

resource "heroku_app" "example" {
  name   = "learn-terraform-heroku-ob"
  region = "us"
}

module "key-value-store" {
  source = "./modules/key-value-store"

  app  = heroku_app.example.id
  plan = "30"
}

modules/key-value-store/main.tf的内容如下：

terraform {
  required_providers {
    mycloud = {
      source  = "heroku/heroku"
      version = "~> 4.6"
    }
  }
}

resource "heroku_addon" "redis" {
  app  = var.app
  plan = "rediscloud:${var.plan}"
}

terraform get做得很好。但是terraform plan给我看了上面的错误！

要使这段代码工作，您必须在根模块和子模块中都有required_providers块。因此，需要做到以下几点：

1. 将required_providers块添加到根模块(这是您已经拥有的)
2. 将required_providers块添加到子模块并将其正确命名(目前您已将其设置为mycloud，provider "heroku" {}块缺失)

需要添加到根模块中的代码是：

terraform {
  required_providers {
    heroku = {
      source = "heroku/heroku"
      version = "~> 4.6"
    }
  }
}

provider "heroku" {}

resource "heroku_app" "example" {
  name   = "learn-terraform-heroku-ob"
  region = "us"
}

module "key-value-store" {
  source = "./modules/key-value-store"

  app  = heroku_app.example.id
  plan = "30"
}

在子模块(即./modules/key-value-store)中，需要有以下内容：

terraform {
  required_providers {
    heroku = { ### not mycloud
      source  = "heroku/heroku"
      version = "~> 4.6"
    }
  }
}

provider "heroku" {} ### this was missing as well

resource "heroku_addon" "redis" {
  app  = var.app
  plan = "rediscloud:${var.plan}"
}

当第二个资源被移动到模块时，它停止工作，因为Heroku不是正式的Terraform提供程序，因此提供程序设置不会传播到模块。对于非官方提供者(例如，标记为verified)，必须定义相应的required_providers和provider <name> {}块。另外，确保删除.terraform目录并重新运行terraform init。
