README

Drupal 11 installation powering the headless backend for decoupled.io. Custom dc_core install profile, FrankenPHP-based Docker image, and a fly.toml for building + pushing the image to Fly.io.

This repo is application code only. Provisioning of Fly tenant apps — the orchestration that spins up a new Drupal site per customer — lives in the decoupled-dashboard repo under scripts/fly/. If you're looking for bin/provision-tenant.sh, it moved there.

Stack

• Drupal 11 on PHP 8.5
• FrankenPHP (Caddy + PHP worker mode) — Dockerfile + Caddyfile in repo root
• PostgreSQL (Drupal runs on Postgres via settings.platform.php)
• APCu for hot cache bins via Drupal's chainedfast backend
• dc_core install profile (see web/profiles/dc_core/)
  • Custom modules: dc_chatbot, dc_config, dc_import, dc_mail, dc_puck, dc_revalidate
  • GraphQL Compose for headless API
  • OAuth consumers auto-generated per install via hook_install()

Local development

DDEV-based local dev (see .ddev/config.yaml):

ddev start
ddev composer install
ddev drush site:install dc_core -y

Building the Fly image

Every tenant on Fly pulls its image from the decoupled-drupal-frankenphp Fly app's registry. To ship a new image:

fly deploy

This builds the FrankenPHP image on Fly's builder, pushes it to registry.fly.io/decoupled-drupal-frankenphp, and redeploys the source app. New tenants provisioned after this automatically pick up the new image (the dashboard's provisioner resolves the current tag at create time).

Rolling the image out to existing tenants is the dashboard's fly-fleet-deploy.yml GitHub Action — it loops over every tenant-* app and fly deploys them against the new tag. Run from the dashboard repo.
