Host asset library with Laravel: relational workflow state

Summary

Deploy a asset library 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 asset library-specific behavior as your application code.

Infrastructure Requirements

  1. Compute

    • Summary: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
    • Status: verified
    • Canonical Path: /discover/primitive/compute
  2. Postgres

    • Summary: Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.
    • Status: verified
    • Canonical Path: /discover/primitive/postgres

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

Success Checks

  1. Description: app responds on its public URL

    • Kind: http_get
    • Path: /
    • Expect: ample canary laravel patterns
  2. Description: transactional-workflows self-test

    • Kind: http_get
    • Path: /p/transactional-workflows
    • Expect: tx=ok history=2 conflict=rejected
