Apollo GraphQL Terraform Provider

Unnoficial Terraform provider for Apollo GraphQL. Enable management of resources like graphs, graph variants, subgraphs, graph API keys, and more using Terraform.

The killer feature of this provider is the extensive schema checks done before a subgraph is created or updated. This make it virtually impossible to deploy an invalid subgraph and break the supergraph because of it. If an errors or warnings are detected, the provider will nicely display them in the Terraform output.

Usage example

In order to use this provider you will need to add the following code to your Terraform configuration file:

terraform {
  required_providers {
    apollostudio = {
      source = "sapher/apollostudio"
      version = ">= 1.3.0"
    }
  }
}

provider "apollostudio" {
  api_key = "<your-api-key>"
  org_id  = "<your-org-id>"
}

All the resources and data sources are documented in the provider documentation page.

Contributions

Any contributions are welcome!

Local development

In the following section, we will see how to setup a local development environment for the provider. This will allow you to test your changes locally and ease the development process.

Prerequisites

API Key

First you will need an account on Apollo GraphQL and you will need to generate an API Key with the GRAPH_ADMIN role for the whole organization. It is recommended to use API key with this role so that all features of the provider are available. Otherwise, if you have to use another role, some resources won't be available.

Tools

The following tools need to be installed on your machine and available in your PATH:

• golang
• terraform

The following tools are optional but highly recommended. They are used to run checks and tests locally:

• pre-commit : Run checks before committing code
• golangci-lint : Linter for Golang codebase
• gitleaks : Analyze git history to find secrets

Clone repository

git clone [email protected]:sapher/terraform-provider-apollostudio.git $HOME/terraform-provider-apollostudio

This will clone this repository in the $HOME/terraform-provider-apollostudio folder. It is important to keep the folder name as terraform-provider-apollostudio otherwise the content of the docs folder will be rendered by the make generate command using a different prefix than the one awaited.

Configure local environment

Next, you need to create or update the file ~/.terraformrc with the following content:

provider_installation {
  dev_overrides {
    "hashicorp.com/sapher/apollostudio" = "/home/<your-username>/terraform-provider-apollo"
  }

  direct {}
}

This will force terraform to use the local provider instead of the published one from the registry.

Note that the path needs to be absolute and should point to the folder where you cloned the repository.

Now you need to build the provider:

cd $HOME/terraform-provider-apollostudio
make build

An executable file named terraform-provider-apollostudio should have been created in the repository root folder.

Usage of the development provider

Now you can create a new main.tf file with the following content:

terraform {
  required_providers {
    apollostudio = {
      source = "hashicorp.com/sapher/apollostudio"
    }
  }
}

provider "apollostudio" {
  api_key = "<your-api-key>"
  org_id  = "<your-org-id>"
}

data "apollostudio_graphs" "this" {}

Unless you use other providers in your code, you don't have to run terraform init as the provider is run from the local machine.

Install git hooks

We use pre-commit to run some checks before committing any code. To install the git hooks, run the following command:

pre-commit install

Be sure to have the tools listed in the prerequisites section installed and available in your PATH.

You can also run pre-commit at any time by running the following command:

pre-commit run --all-files

Runs acceptance tests locally

Before running any of the following commands, you need to export these environment variables:

export APOLLO_API_KEY=<your-api-key>
export APOLLO_ORG_ID=<your-org-id>

As acceptance tests are run against a real Apollo GraphQL organization, we need to create a dedicated graph for the tests.

For this you need to go to your dashboard and create a new graph with the following settings:

Name	Value
Graph Name	testacc-terraform
Graph ID	testacc-terraform - ⚠️ do not use autogenerated id
Description	graph dedicated for terraform provider acceptance testing
Subgraph Name	countries
Routing URL	https://countries.trevorblades.com

Then you can run the acceptance tests :

make testacc
