Terraform Link Docs

This extension adds provider links to resources, data blocks and module sources in your Terraform files, with support for multiple documentation registries including Terraform Registry, OpenTofu, Library.tf, and custom URL templates.

Demo

Features

• Multi-registry docs support: registry.terraform.io, search.opentofu.org, library.tf, or custom templates.

Provider Resources

Resources and data sources are automatically linked to their documentation.

resource "aws_instance" "web" {}

data "aws_ami" "example" {}

Community Providers

The extension parses required_providers blocks to correctly link resources from community or partner providers to the Terraform Registry (e.g. Cloudflare, etc.).

terraform {
  required_providers {
    cloudflare = {
      source = "cloudflare/cloudflare"
    }
  }
}

resource "cloudflare_record" "example" {}

Modules

Below are generic examples of module sources where appropriate links are added.

Local Paths

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

Terraform Registry

module "consul" {
  source = "hashicorp/consul/aws"
  version = "0.1.0"
}

module "consul" {
  source = "app.terraform.io/example-corp/k8s-cluster/azurerm"
  version = "1.1.0"
}

module "vpc" {
  source  = "terraform-aws-modules/vpc/aws"
  version = "5.0.0"
}

# Submodules
module "" {
  source  = "terraform-aws-modules/iam/aws//modules/iam-assumable-role"
  version = "5.33.1"
}

Github

module "consul" {
  source = "github.com/hashicorp/example"
}

module "consul" {
  source = "git@github.com:hashicorp/example.git"
}

Generic Git Repository

module "eks_cluster" {
  source = "git::git@github.com:owner/repo.git//modules/eks-cluster"
}

# select a revision
module "eks_cluster" {
  source = "git::git@github.com:owner/repo.git//modules/eks-cluster?ref=v0.0.1"
}

# directly select a commit using its SHA-1 hash
module "eks_cluster" {
  source = "git::git@github.com:owner/repo.git//modules/eks-cluster?ref=51d462976d84fdea54b47d80dcabbf680badcdb8"
}

# "scp-like" address syntax
module "storage" {
  source = "git::username@example.com:repo/storage.git"
}

Bitbucket

module "consul" {
  source = "bitbucket.org/hashicorp/terraform-consul-aws"
