Host product catalog with Symfony: relational catalog data

Deploy a product catalog built with Symfony 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 Symfony: 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 product catalog-specific behavior as your application code.

Representative Queries

• Host product catalog with Symfony: relational catalog data
• Where can I host Product catalog built with Symfony?
• I need catalog tables, transactional update logic and application-level access boundaries.

Resource Requirements

• Compute
• Postgres

Infrastructure Requirements

1. Compute

   • Status: verified
   • Summary: 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

   • Status: verified
   • 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.

Execution Status

ready

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)
• 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 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 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

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 product catalog itself (your domain records, validation rules and concurrency policy) 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.
• 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; monthlyAmount=5.0
• managed PostgreSQL database: size=s-1vcpu-1gb; quantity=1.0; monthlyAmount=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

• Kind: canary_run
  • Summary: Symfony pattern fixture deployed on Ample (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); checks passed for transactional-workflows and configuration-secrets. Pattern proof: 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).
