Drupal on Aruba Cloud
Deploy Drupal 10 — a flexible, enterprise-grade open-source CMS — on Aruba Cloud using Terraform and cloud-init. Drupal is installed via Composer with a managed MySQL 8.0 DBaaS backend, following the same production pattern as the WordPress example.
Provider version: arubacloud/arubacloud
~> 0.5| Terraform: ≥ 1.9
Introduction
Drupal 10 is built on the drupal/recommended-project Composer template, which bundles Drupal core, Drush (the Drupal CLI), and sensible defaults for production. This example provisions:
- Apache2 + PHP 8.1 with all Drupal-required extensions
- Drupal 10 installed via Composer + Drush in fully unattended mode
- Managed MySQL 8.0 via ArubaCloud DBaaS — Drupal never touches raw SQL
- Ports 80 and 443 open to the internet
- Optional HTTPS via Let's Encrypt when
domainis set
Bootstrap time: Composer downloads ~80 MB of PHP packages. Expect 15–20 minutes before the site is reachable.

Deployment Instructions
1. Clone and navigate
git clone https://github.com/arubacloud/terraform-arubacloud-examples.git
cd terraform-arubacloud-examples/drupal
2. Configure variables
cp terraform.tfvars.example terraform.tfvars
Set credentials, passwords, and admin email:
db_password = "your-strong-db-password"
admin_email = "admin@example.com"
admin_password = "your-strong-admin-password"
3. Deploy
terraform init
terraform plan
terraform apply
Bootstrap takes 15–20 minutes — Composer downloads and DBaaS provisioning run in parallel.
4. Access Drupal
terraform output site_url
terraform output admin_url
Log in with admin_user and admin_password.
Troubleshooting
Site not loading after apply
The bootstrap is still running. Check progress:
ssh ubuntu@$(terraform output -raw vm_public_ip)
sudo tail -f /var/log/cloud-init-output.log
Drush site:install failed
Check if DBaaS was reachable:
nc -zv $(terraform output -raw db_host) 3306
sudo cat /var/log/cloud-init-output.log | grep -A5 "ERROR\|Waiting"
