Deploy
Goal
This snapshot advances Keystone Gazette by teaching you to prepare Keystone Gazette for Platform.sh / Docker with managed MySQL.
Every numbered folder is a complete app. Run this stage independently, then compare it with the previous folder.
Prerequisites
Use PHP 8.2+, Composer, and Docker for MySQL stages.
Port 8002 must be free. Copy .env.example before starting database stages.
- PHP 8.2+ and Composer
- A code editor and terminal
- Docker from part 4 onward
Concepts
Production needs HTTPS cookies, a strong APP_SECRET, and env-only database URLs.
Keep controllers thin: forms accept input, Doctrine entities enforce rules, and Twig escapes output by default.
Walkthrough
Review deploy docs; never commit .env.
Read the example, then open the matching snapshot. The repository includes the surrounding setup and error handling.
APP_ENV=prod\nDATABASE_URL=mysql://...
Run and verify
Enter 12-Deploy, install Composer deps, copy .env.example, and start the Symfony server on port 8002.
Open http://127.0.0.1:8002. Watch the terminal for validation and database errors.
docker compose up -d
git clone https://github.com/michaeldunga1/fcc-symfony-blog.git
cd fcc-symfony-blog/12-Deploy
composer install
cp .env.example .env
symfony server:start --port=8002 --no-tls
# or: php -S 127.0.0.1:8002 -t public
Troubleshooting
If sessions vanish after deploy, check HTTPS cookie settings.
For database failures, confirm Docker and the keystone_NN name when applicable. Never commit .env or vendor.
- Read the first error first
- Restart after environment changes
- Never commit secrets
Try this
List every secret that must live only in the host environment.
Test a happy path and one invalid or unauthorized request.
- Make one small change
- Test it in the browser
- Compare with the next snapshot only after it works
