# Connect Postgres for Symfony

## Summary
Database connection for a Symfony app on Ample. Verified on Symfony: a managed PostgreSQL database auto-provisioned and injected as DATABASE_URL, with real queries succeeding at request time (records=ok). Build and start: composer install --no-dev from composer.lock with Symfony Runtime's dotenv disabled (extra.runtime.disable_dotenv; .env never ships, its values arrive as encrypted env, and compile-time parameters such as DEFAULT_URI need a default), then FrankenPHP serving public/ (php-server with the index.php fallback) reading PORT on the php-8.5 template with APP_ENV=prod.

## Representative Queries
- Connect Postgres for Symfony
- Where can I host Connect Postgres built with Symfony?
- I need driver setup, connection settings, secret handling and a real connection test.

## Resource Requirements
- primitive:compute
- primitive:postgres

## Infrastructure Requirements
- **Compute**: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
- **Postgres**: Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.

## Prerequisites
- A Symfony project (composer install --no-dev from composer.lock with Symfony Runtime's dotenv disabled (extra.runtime.disable_dotenv; .env never ships, its values arrive as encrypted env, and compile-time parameters such as DEFAULT_URI need a default), then FrankenPHP serving public/ (php-server with the index.php fallback) reading PORT on the php-8.5 template with APP_ENV=prod)
- A PostgreSQL driver reading DATABASE_URL at runtime
- An Ample account token with servers:write, databases:read

## Workflow Steps
1. **Build and start**: composer install --no-dev from composer.lock with Symfony Runtime's dotenv disabled (extra.runtime.disable_dotenv; .env never ships, its values arrive as encrypted env, and compile-time parameters such as DEFAULT_URI need a default), then FrankenPHP serving public/ (php-server with the index.php fallback) reading PORT on the php-8.5 template with APP_ENV=prod; the server must bind 0.0.0.0 on PORT.
2. **Read DATABASE_URL at runtime**: Open connections from the environment inside handlers or a pool; omit DATABASE_URL to auto-provision a managed database or pass --env DATABASE_URL=... for an existing one.
3. **Verify**: Fetch the live URL and /p/relational-records on the example; on failure read the build and runtime logs. Command: ample logs --kind build

## Examples
- **Symfony pattern fixture**: Verified database connection on Symfony. Source Reference: tests/deploy-canaries/symfony-patterns

## Success Checks
- App responds on its public URL (kind: http_get, path: /, expect: ample canary symfony patterns).
- Relational-records check from the example (kind: http_get, path: /p/relational-records, expect: see the pattern fixture checks).

## Limitations
- Verified on the php-8.5 template at s-1vcpu-1gb; other sizes and Symfony major versions are not verified.
- Region, compliance attestations and request-duration limits are unknown and not claimed.
- Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified.

## Cost Estimate
- **Currency**: USD
- **Monthly Amount**: $10.00
- **Basis**: size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty

### Components
- **App server**: size: s-1vcpu-1gb, quantity: 1.0, monthly amount: $5.0
- **Managed PostgreSQL database**: size: s-1vcpu-1gb, quantity: 1.0, monthly amount: $5.0

### Note
Always-on monthly price of the tested sizes; apps auto-pause when idle. Buckets are allocation-priced per quota and not included.
