## The short version

Deploy an 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.

### WHAT WAS VERIFIED

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).

## INFRASTRUCTURE

### What it needs

- [Compute](/content/discover/primitive/compute/index.html): verified (Apps run in isolated x86\_64 Firecracker microVMs; sizes are the priced VM sizes.)
- [Postgres](/content/discover/primitive/postgres/index.html): 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](/content/discover/primitive/s3-compatible-object-storage/index.html): verified (Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.)

## PREREQUISITES

### Before you start

- 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

## STEP BY STEP

### How to do it

1. 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. 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). Copy the approach into your schema; keep migrations idempotent and run them with --release-command.

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. 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.

```
   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=...
   ```

5. 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. On failure read `ample logs <deployment_id> --kind build` then `--kind runtime`.

```
   ample logs <deployment_id> --kind build
   ```

## EXAMPLES

### Tested examples

- **Symfony pattern fixture** (`tests/deploy-canaries/symfony-patterns`): Multi-pattern Symfony app whose bulk import staging module was checked live; the module is under tests/deploy-canaries/_pattern-modules.

## SUCCESS CHECKS

### How to know it worked

- app responds on its public URL (`/` on the live URL, expect ample canary symfony patterns)
- bulk-import-staging self-test (`/p/bulk-import-staging` on the live URL, expect imported=2 rejected=1 restart=ok)

## COST

### Cost estimate

Estimated 10.00 USD per month (size prices from pricing.toml at build revision ca0b484a7a9957c573a88d3a32dc603c3c10135a).

- app server x1 `s-1vcpu-1gb`: 5.00 USD
- managed PostgreSQL database x1 `s-1vcpu-1gb`: 5.00 USD

Upper-bound monthly price of the tested sizes. Buckets are allocation-priced per quota and not included.

## EVIDENCE
