Convert Terraform Provider Configuration to JSON

Terraform Provider Configuration

Provider blocks configure the cloud provider plugins that Terraform uses to manage infrastructure. Multi-region and multi-account setups use provider aliases.

HCL Provider Configuration

terraform {
  required_version = ">= 1.5"

  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.0"
    }
    random = {
      source  = "hashicorp/random"
      version = "~> 3.5"
    }
  }

  backend "s3" {
    bucket = "my-terraform-state"
    key    = "prod/terraform.tfstate"
    region = "us-east-1"
  }
}

provider "aws" {
  region = "us-east-1"

  default_tags {
    tags = {
      ManagedBy = "terraform"
    }
  }
}

provider "aws" {
  region = "eu-west-1"
}

JSON Structure

The terraform block contains required_version, required_providers, and backend as nested structures. Provider blocks are keyed by provider name:

{
  "terraform": {
    "required_version": ">= 1.5",
    "required_providers": {
      "aws": {
        "source": "hashicorp/aws",
        "version": "~> 5.0"
      }
    },
    "backend": {
      "s3": {
        "bucket": "my-terraform-state",
        "key": "prod/terraform.tfstate",
        "region": "us-east-1"
      }
    }
  },
  "provider": {
    "aws": {
      "region": "us-east-1"
    }
  }
}

Provider Aliases

Multiple provider configurations for the same provider use aliases. In HCL:

provider "aws" {
  alias  = "eu"
  region = "eu-west-1"
}

Version Constraints

The ~> 5.0 version constraint means "any 5.x version". Other operators include >=, <=, !=, and exact version pins.
