# Host order tracking with Symfony: inventory imports

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

## Representative Queries
- Host order tracking with Symfony: inventory imports
- Where can I host Order tracking 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**: 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**: 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**: Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.

## 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
- An Ample account token with servers:write, databases:read, buckets:read

## 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

## Workflow Steps
1. **Build and start**: 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. The server must bind 0.0.0.0 on PORT.
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. 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). Re-running with no change is a no-op.
5. **Verify**: Fetch the live URL and the pattern self-test route(s) (/p/bulk-import-staging) from the example; then run your own checks.

## Cost Estimate
- **Currency**: USD
- **Monthly Amount**: 10.0
- **Basis**: size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty

### Components
- **App server**: s-1vcpu-1gb - quantity: 1.0 - monthlyAmount: 5.0
- **Managed PostgreSQL database**: s-1vcpu-1gb - quantity: 1.0 - monthlyAmount: 5.0

## 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 order tracking itself (your import format, mapping and conflict rules) is application code and was not separately tested; the pattern checks are what was verified.
- Apps auto-pause when idle and wake on the next request; always-on is an operator setting, not a plan feature.
- Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified; apps and their databases are placed together.

## Evidence Summary
- **Summary**: Symfony pattern fixture deployed on Ample; checks passed for bulk-import-staging and configuration-secrets.
- **Observed At**: 2026-09-20T22:23:52Z
- **Scope**: checks: [/p/bulk-import-staging], pattern: pattern:bulk-import-staging, template: php-8.5.
