Safety Rules

1. **Verify environment is running:**

   ddev list

2. **Always create backups before destructive actions** (e.g. `import-db`, `cim`). 3. **Check `ddev config` validity** before rebuilding environments. 4. **Validate `composer.json`** before Composer operations. 5. **Never commit credentials or `.ddev/secrets`** to version control.

Common Workflows

Installing a New Module

1. `ddev composer require drupal/[module_name]` 2. `ddev drush en [module_name] -y` 3. `ddev drush cr` 4. `ddev drush cex -y` (optional)

Updating Drupal Core

1. `ddev export-db --file=backup.sql` 2. `ddev composer update drupal/core* --with-dependencies` 3. `ddev drush updb -y` 4. `ddev drush cr` 5. Test the site

Deploying Configuration

1. On dev: `ddev drush cex -y` 2. Commit exported configs 3. On target env: `ddev pull` 4. `ddev drush cim -y` 5. `ddev drush cr`

Creating a Custom Module

1. `mkdir -p web/modules/custom/[module_name]` 2. Create `[module_name].info.yml` 3. Add routes/controllers/forms as needed 4. `ddev drush en [module_name] -y` 5. `ddev drush cr`

Monitoring and Debugging

Log Files

ddev drush watchdog:show
ddev logs web
ddev logs db

Health Checks

ddev list
ddev drush status
ddev exec "df -h"
ddev exec "php -v"

Environment Variables

Typical variables managed by DDEV:

• `DRUPAL_VERSION=11`
• `PHP_VERSION=8.3`
• `MYSQL_DATABASE=drupal`
• `DDEV_PROJECT` (project name)
• `.ddev/config.yaml` controls PHP, webroot, and DB settings.

---

Best Practices

1. Use **Composer** for all code changes. 2. Keep **config in Git**. 3. Use **Drush** over the web UI for reliability. 4. Update order: Composer → DB updates → Cache clear. 5. Test locally with `ddev` before deploying. 6. Avoid wildcards (`*`) in `composer.json`. 7. Automate **database and files backups**. 8. Never modify core or contrib modules directly.
