# Host knowledge base with Laravel: Postgres-backed content ## Summary Deploy a knowledge base built with Laravel on Ample using the relational records 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, and a published bucket serves public assets from the CDN host. Verified on Laravel: a workspace-scoped table, an explicit state machine (draft to review to published) that rejects invalid transitions, and a cross-workspace read that returns nothing (transitions=true isolation=true). Not separately tested: your record schema, states and access rules; treat the knowledge base-specific behavior as your application code. ## Infrastructure requirements - Compute: verified (Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.) - Postgres: 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.) - CDN: verified (The CDN host serves objects from published buckets. It does not front app compute and is not a cache or key-value store.) ## Prerequisites - 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) - 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 ## Exact 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` ## 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 relational records: a workspace-scoped table, an explicit state machine (draft to review to published) that rejects invalid transitions, and a cross-workspace read that returns nothing (transitions=true isolation=true). Copy the approach into your schema; keep migrations idempotent and run them with --release-command. 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. Publish only the bucket that serves public assets and reference its CDN URL. 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 --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=... --env CDN_PUBLIC_URL=... ``` 5. **Verify.** Fetch the live URL and the pattern self-test route(s) (/p/relational-records) from the example; then run your own checks. On failure read `ample logs --kind build` then `--kind runtime`. ``` ample logs --kind build ``` ## Tested examples - **Laravel pattern fixture** (tests/deploy-canaries/laravel-patterns): Multi-pattern Laravel app whose relational records module was checked live; the module is under tests/deploy-canaries/_pattern-modules. ## Success checks - app responds on its public URL (`/` on the live URL, expect ample canary laravel patterns) - relational-records self-test (`/p/relational-records` on the live URL, expect records=ok transitions=true isolation=true) ## Limitations - 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. - The knowledge base itself (your record schema, states and access rules) 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. - PutObject and GetObject with path-style addressing are verified; multipart upload, listing, presigned URLs and lifecycle rules are not. - The CDN serves published-bucket objects only; cache rules, purge and TTL control are not verified (the fixture sets Cache-Control on upload and versions keys). ## Cost estimate Estimated 10.00 USD per month (size prices from pricing.toml at build revision a1b8c38919e59cd035ebabaced73cf84ece24371). - app server x1 `s-1vcpu-1gb`: 5.00 USD - managed PostgreSQL database x1 `s-1vcpu-1gb`: 5.00 USD Always-on monthly price of the tested sizes; apps and databases auto-pause when idle. Buckets are allocation-priced per quota and not included. ## Verification evidence - canary_run on 2026-09-20T20:36:21Z at revision `118ad1c6d7d23d4c2ce069254bab9ec9d37cd57b-dirty (CLI 118ad1c)`: 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 relational-records and configuration-secrets.
