# Host subscription content with Symfony: public product media

## Summary

Deploy a subscription content 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 subscription content-specific behavior as your application code.

## Infrastructure requirements

- Compute: verified (Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.)
- Postgres: verified (Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.)
- S3-compatible object storage: verified (Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.)
- CDN: verified (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 (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 (auto-provisioned when omitted, or supplied with --env)
- A bucket from `ample bucket create` with its credentials passed as encrypted S3_* environment variables and a second, published bucket for public assets (CDN_*)
- An Ample account token with servers:write, databases:read, buckets:read

## Exact tested configuration

- template: `php-8.5`
- runtime: `php`
- size: `s-1vcpu-1gb`
- install: `composer install --no-dev --prefer-dist --no-interaction --no-progress --optimize-autoloader`
- start: `frankenphp php-server --listen :$PORT --root public`

## 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 public media library; 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. Keep private data in an unpublished bucket. Publish only the bucket that serves public assets and reference its CDN URL.
4. **Deploy.** Run the synchronous deploy once and read the result (exit 0 live, 1 failed, 2 blocked). 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. On failure read `ample logs <deployment_id> --kind build` then `--kind runtime`.

## Tested examples

- **Symfony pattern fixture**: Multi-pattern Symfony app whose public media library module was checked live.

## Success checks

- app responds on its public URL
- public-media-library self-test 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 subscription content itself is application code and was not separately tested; the pattern checks are what was verified.
- Region, compliance attestations and request-duration limits are unknown and not claimed.
- Apps auto-pause when idle and wake on the next request; always-on is an operator setting, not a plan feature.

## Cost estimate

Estimated 10.00 USD per month:
- app server x1 `s-1vcpu-1gb`: 5.00 USD
- managed PostgreSQL database x1 `s-1vcpu-1gb`: 5.00 USD

## Verification evidence

- canary_run on 2026-09-20: Symfony pattern fixture deployed on Ample; checks passed for public-media-library and configuration-secrets.
