Host digital downloads with Symfony: authorized file delivery

Summary

Deploy a digital downloads built with Symfony on Ample using the generated downloads 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: an export query rendered to a CSV artifact stored with metadata in a private bucket and returned only to an authorized caller (401 without token, export=ok rows=3). Not separately tested: your export formats, retention policy and entitlement model; treat the digital downloads-specific behavior as your application code.

Representative Queries

• Host digital downloads with Symfony: authorized file delivery
• Where can I host Digital downloads built with Symfony?
• I need a file entitlement model and an application-enforced download authorization flow.

Resource Requirements

• primitive:compute
• primitive:postgres
• primitive:s3-compatible-object-storage

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. The server must bind 0.0.0.0 on PORT.

2. Implement the pattern on PostgreSQL
   The fixture's module implements generated downloads: an export query rendered to a CSV artifact stored with metadata in a private bucket and returned only to an authorized caller. 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. Use path-style addressing.

4. Deploy
   Run the synchronous deploy once and read the result. Re-running with no change is a no-op.

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

Examples

• Symfony pattern fixture
  Multi-pattern Symfony app whose generated downloads module was checked live.

Success Checks

• App responds on its public URL.
• Generated-downloads self-test.

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 digital downloads themselves are application code and were not separately tested.

Cost Estimate

• Monthly Amount: $10.00
  • App server: s-1vcpu-1gb
  • Managed PostgreSQL database: s-1vcpu-1gb
