Host vendor portal with Rails: private documents

Deploy a vendor portal built with Rails on Ample using the private document library 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. Verified on Rails: a role-to-document access model with negative tests (401 without identity, 403 for the wrong role) and a private-bucket round-trip for the allowed role (private=ok). Not separately tested: your identity integration and role assignments; treat the vendor portal-specific behavior as your application code.

Input Schema

• env: Encrypted environment variables (bucket credentials, secrets).
• name: App name.
• path: Project directory or ample.toml service.
• release_command: Migration command run before activation.

Workflow Steps

1. Build and start
   Bundle install into vendor/bundle from Gemfile.lock (development and test groups skipped), then Puma via rails server reading PORT on the ruby-3.4 template with RAILS_ENV=production. The server must bind 0.0.0.0 on PORT.
2. Implement the pattern on PostgreSQL
   The fixture's module implements the private document library: a role-to-document access model with negative tests.
3. Wire object storage
   Create the bucket(s), then pass endpoint, region, bucket and keys as --env values.
4. Deploy
   Run the synchronous deploy once and read the result.
5. Verify
   Fetch the live URL and run your own checks.

Limitations

• Verified on the ruby-3.4 template at s-1vcpu-1gb with the example fixture; other sizes and versions are not verified.
• The vendor portal itself (identity integration and role assignments) is application code and hasn’t been tested separately.
• Apps auto-pause when idle and wake on the next request.

Cost Estimate

• Monthly Amount: $10.0 USD
  • Components:
    • App server (s-1vcpu-1gb): $5.0
    • Managed PostgreSQL database (s-1vcpu-1gb): $5.0

Evidence Summary

• Rails pattern fixture deployed on Ample; checks passed for private-document-library and configuration-secrets.
• The same Rails app deployed with a --release-command migration; the marker was readable after activation.

Example

• Multi-pattern Rails app whose private document library module was checked live.
