### Host marketplace with Symfony: public product media

**Summary**  
Deploy a marketplace built with Symfony on Ample using the public media library pattern. Compute runs the app in an isolated microVM behind a public HTTPS URL, a managed PostgreSQL 16 database is auto-provisioned and injected as DATABASE_URL, a private S3-compatible bucket holds objects with credentials delivered as encrypted environment variables, and a published bucket serves public assets from the CDN host. Verified on Symfony: an object written to a published bucket with an immutable Cache-Control header, a mapping row, and the CDN URL serving it publicly. Not separately tested: your media processing, object layout and cache policy; treat the marketplace-specific behavior as your application code.

### Representative Queries
- Host marketplace with Symfony: public product media
- Where can I host Marketplace built with Symfony?
- I need product-to-object mappings and a tested public media delivery path.

### Resource Requirements
- primitive:compute
- primitive:postgres
- primitive:s3-compatible-object-storage
- primitive:cdn

### Infrastructure Requirements
1. **Compute**  
   - **Status:** verified  
   - **Summary:** Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
2. **Postgres**  
   - **Status:** verified  
   - **Summary:** Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.
3. **S3-compatible object storage**  
   - **Status:** verified  
   - **Summary:** Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.
4. **CDN**  
   - **Status:** verified  
   - **Summary:** The CDN host serves objects from published buckets. It does not front app compute and is not a cache or key-value store.

### Prerequisites
- A Symfony project that builds and starts with the documented commands (composer install --no-dev from composer.lock with Symfony Runtime's dotenv disabled), 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.
- A bucket from `ample bucket create` with its credentials passed as encrypted S3_* environment variables and a second, published bucket for public assets.
- An Ample account token with servers:write, databases:read, buckets:read.

### Workflow Steps
1. **Build and start**  
   Run: `composer install --no-dev` from composer.lock.
2. **Implement the pattern on PostgreSQL**  
   Copy the approach into your schema; keep migrations idempotent and run them with --release-command.
3. **Wire object storage**  
   Create the bucket(s), then pass endpoint, region, bucket and keys as --env values.
4. **Deploy**  
   Run the synchronous deploy once and read the result. Command: `ample deploy . --name --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=...`
5. **Verify**  
   Fetch the live URL and the pattern self-test route(s).

### Examples
- **Symfony pattern fixture**  
  Multi-pattern Symfony app whose public media library module was checked live; the module is under tests/deploy-canaries/_pattern-modules.

### Limitations
- Verified on the php-8.5 template at s-1vcpu-1gb with the example fixture; not verified on other sizes and templates.
- The marketplace's behavior (your media processing, object layout and cache policy) was not tested separately.

### Cost Estimate
- **Monthly Amount:** 10.0 USD  
   - **Basis:** price from pricing.toml.  
   - **Components:**  
     - App server: s-1vcpu-1gb - 5.0 USD.
     - Managed PostgreSQL database: s-1vcpu-1gb - 5.0 USD.
