### Host csv import tool with Laravel: relational workflow state

**Summary**: Deploy a csv import tool built with Laravel on Ample using the transactional workflows 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. Verified on Laravel: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected). Not separately tested: your domain records, validation rules and concurrency policy; treat the csv import tool-specific behavior as your application code.

### Representative Queries
- Host csv import tool with Laravel: relational workflow state
- Where can I host CSV import tool built with Laravel?
- I need a domain record schema, validation rules and concurrency behavior.

### Resource Requirements
- **primitive:compute**
- **primitive:postgres**

### Infrastructure Requirements
- **Compute**:  Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
- **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.

### Prerequisites
1. A Laravel project that builds and starts with the documented commands (composer install --no-dev from composer.lock, then FrankenPHP serving public/ (php-server with the index.php fallback) reading PORT on the php-8.5 template).
2. A PostgreSQL driver reading DATABASE_URL at runtime (auto-provisioned when omitted, or supplied with --env).
3. An Ample account token with servers:write, databases: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, then FrankenPHP serving public/ (php-server with the index.php fallback) reading PORT on the php-8.5 template. The server must bind 0.0.0.0 on PORT.
2. **Implement the pattern on PostgreSQL**: The fixture's module implements transactional workflows: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected). Copy the approach into your schema; keep migrations idempotent and run them with --release-command.
3. **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. Command: ample deploy . --name  --public
4. **Verify**: Fetch the live URL and the pattern self-test route(s) (/p/transactional-workflows) from the example; then run your own checks. On failure read `ample logs  --kind build` then `--kind runtime`. Command: ample logs  --kind build

### Examples
- **Laravel pattern fixture**: Multi-pattern Laravel app whose transactional workflows module was checked live; the module is under tests/deploy-canaries/_pattern-modules.

### Success Checks
- **App responds on its public URL**: kind: http_get, path: /, expect: ample canary laravel patterns
- **Transactional-workflows self-test**: kind: http_get, path: /p/transactional-workflows, expect: tx=ok history=2 conflict=rejected

### Limitations
1. Verified on the php-8.5 template at s-1vcpu-1gb with the example fixture; other sizes, templates and Laravel major versions are not verified.
2. The csv import tool itself (your domain records, validation rules and concurrency policy) is application code and was not separately tested; the pattern checks are what was verified.
3. Region, compliance attestations and request-duration limits are unknown and not claimed.
4. Apps auto-pause when idle and wake on the next request; always-on is an operator setting, not a plan feature.
5. Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified; apps and their databases are placed together.

### 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**: size s-1vcpu-1gb, quantity 1.0, monthly amount 5.0
  - **Managed PostgreSQL database**: size s-1vcpu-1gb, quantity 1.0, monthly amount 5.0
- **Note**: Always-on monthly price of the tested sizes; apps and databases auto-pause when idle. Buckets are allocation-priced per quota and not included.

### Evidence Summary
1. **Canary Run**: Laravel pattern fixture deployed on Ample (composer install --no-dev from composer.lock, then FrankenPHP serving public/ (php-server with the index.php fallback) reading PORT on the php-8.5 template); checks passed for transactional-workflows and configuration-secrets.

2. **Canary Run**: The same Laravel app deployed with a --release-command migration; the marker it created was readable after activation.
