Hookdeck Terraform Provider

The Hookdeck Event Gateway enables engineering teams to build, deploy, observe, and scale event-driven applications. For more information, see the Hookdeck documentation.

The Hookdeck Terraform provider enables you to manage your Hookdeck workspaces using IaC (Infrastructure-as-Code), including managing your sources, destinations, connections, transformations, and more. It also supports webhook registration workflow that allows you to configure webhooks as part of your CI/CD processes.

Installation

To install Hookdeck Terraform provider:

Obtain your Hookdeck API key from the dashboard
Add the following to your Terraform configuration file:

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

provider "hookdeck" {
  # set HOOKDECK_API_KEY env var or optionally specify the key in the provider configuration
  api_key = var.hookdeck_api_key
}

Using the provider

This README gives a basic example; for more examples, see the examples/ folder, the rendered documentation on the Terraform Registry, or docs folder in this repository.

# Configure a source
resource "hookdeck_source" "my_source" {
  name = "my_source"
}

# Configure a destination
resource "hookdeck_destination" "my_destination" {
  name = "my_destination"
  type = "HTTP"
  config = jsonencode({
    url  = "https://myapp.example.com/api"
  })
}

# Configure a connection
resource "hookdeck_connection" "my_connection" {
  source_id      = hookdeck_source.my_source.id
  destination_id = hookdeck_destination.my_destination.id
}

For Source config and Destination config you must provide a JSON object. This means you do not get validation on the config property within your IDE or when running terraform plan. However, when running terraform apply the Hookdeck API will provide error responses if invalid configuration is received.

Dependencies

This provider is built on top of the Hookdeck API.

Development

Running locally

See https://developer.hashicorp.com/terraform/tutorials/providers-plugin-framework/providers-plugin-framework-provider#prepare-terraform-for-local-provider-install

Brief details

Build and install:

go build
go install

Override the provider in a ~/.terraformrc:

provider_installation {

  dev_overrides {
      "hookdeck/hookdeck" = "/Users/leggetter/go/bin"
  }

  # For all other providers, install them directly from their origin provider
  # registries as normal. If you omit this, Terraform will _only_ use
  # the dev_overrides block, and so no other providers will be available.
  direct {}
}

Release

Released are managed via GitHub Releases.

To release, create a new release with a name representing the SemVer version. Also, create a tag with the same version. A GitHub action is triggered via the new Tag creation and uses GoReleaser to create a new set of release assets for the Hookdeck Terraform Provider.
