## Host marketplace with Symfony: inventory imports

Deploy a marketplace built with Symfony on Ample using the bulk import staging 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. Verified on Symfony: a CSV staged as an object, row-level validation with per-row errors recorded, and a restart-safe import keyed by import id (imported=2 rejected=1 restart=ok). Not separately tested: your import format, mapping and conflict rules; treat the marketplace-specific behavior as your application code.

### Representative Queries
- Host marketplace with Symfony: inventory imports
- Where can I host Marketplace built with Symfony?
- I need an inventory import contract, staging objects and row-level error handling.

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

### 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.

### Workflow Steps
1. **Build and start**  
   composer install --no-dev from composer.lock with Symfony Runtime's dotenv disabled, then FrankenPHP serving public/ reading PORT on the php-8.5 template with APP_ENV=prod.

2. **Implement the pattern on PostgreSQL**  
   The fixture's module implements bulk import staging: a CSV staged as an object, row-level validation with per-row errors recorded, and a restart-safe import keyed by import id (imported=2 rejected=1 restart=ok).

3. **Wire object storage**  
   Create the bucket(s), then pass endpoint, region, bucket and keys as --env values. Use path-style addressing.

4. **Deploy**  
   Run the synchronous deploy once and read the result.

5. **Verify**  
   Fetch the live URL and the pattern self-test route(s) from the example; then run your own checks.

### Limitations
- Verified on the php-8.5 template at s-1vcpu-1gb with the example fixture; other sizes, templates and Symfony major versions are not verified.
- The marketplace itself (your import format, mapping and conflict rules) is application code and was not separately tested.

### Cost Estimate
- **Currency**: USD
- **Monthly Amount**: 10.0
- **Basis**: size prices from pricing.toml
- **Components**:
  - App server: s-1vcpu-1gb (Quantity: 1, Monthly Amount: 5.0)
  - Managed PostgreSQL database: s-1vcpu-1gb (Quantity: 1, Monthly Amount: 5.0)

### Examples
- **Symfony pattern fixture**: Multi-pattern Symfony app whose bulk import staging module was checked live.

### Success Checks
1. App responds on its public URL: **expected** - ample canary symfony patterns.
2. Bulk-import-staging self-test: **expected** - imported=2 rejected=1 restart=ok.
