Host order tracking with Symfony: authorized file delivery

Summary

Deploy a order tracking 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 order tracking-specific behavior as your application code.

Infrastructure requirements

Prerequisites

Exact tested configuration

Steps

  1. Build and start. composer install --no-dev from composer.lock with Symfony Runtime's dotenv disabled. 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 (401 without token, export=ok rows=3).
  3. Wire object storage. Create the bucket(s), then pass endpoint, region, bucket and keys as --env values. Use path-style addressing. Keep private data in an unpublished bucket.
  4. Deploy. Run the synchronous deploy once and read the result (exit 0 live, 1 failed, 2 blocked).
   ample deploy . --name <app-name> --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...
  1. Verify. Fetch the live URL and the pattern self-test route(s) (/p/generated-downloads); then run your own checks.
