tfjson's Introduction

tfjson

Utility to read in a Terraform plan file and dump it out in JSON.

Installation

$ go get github.com/mike-dunton/tfjson

Usage

Given the following Terraform resources:

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

resource "aws_vpc" "main" {
  cidr_block = "10.0.0.0/16"
}

module "inner" {
  source = "./inner"
}

// in inner module:

resource "aws_vpc" "inner" {
  cidr_block = "10.0.0.0/8"
}

Running terraform plan -out=terraform.tfplan produces a Terraform plan file. The JSON representation produced by tfjson looks like:

$ tfjson terraform.tfplan
{
    "aws_vpc.main": {
        "cidr_block": "10.0.0.0/16",
        "default_network_acl_id": "",
        "default_route_table_id": "",
        "default_security_group_id": "",
        "destroy": false,
        "destroy_tainted": false,
        "dhcp_options_id": "",

    },
