## Configure build and start for Rails

### Summary
Build and start for a Rails app on Ample. Verified on Rails: the app built and started with the documented commands and answered on its public HTTPS URL. 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`.

### Prerequisites
- A Rails project (`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`)
- An Ample account token with `servers:write`

### 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. **Deploy**  
   Run the synchronous deploy once and read the result.  
   Command: `ample deploy . --name  --public`
3. **Verify**  
   Fetch the live URL on the example; on failure read the build and runtime logs.  
   Command: `ample logs  --kind build`

### Tested Configuration
- **Template**: ruby-3.4  
- **Runtime**: ruby  
- **Size**: s-1vcpu-1gb  
- **Install**: `bundle config set --local path vendor/bundle && bundle config set --local without 'development test' && bundle install`  
- **Start**: `bundle exec rails server -b 0.0.0.0 -p $PORT`

### Success Checks
- **App responds on its public URL**  
  Kind: `http_get`  
  Path: `/`  
  Expect: `ample canary rails patterns`

### Limitations
- Verified on the `ruby-3.4` template at `s-1vcpu-1gb`; other sizes and Rails major versions are not verified.
- Region, compliance attestations, and request-duration limits are unknown and not claimed.

### Cost Estimate
- **Currency**: USD  
- **Monthly Amount**: 5.0  
- **Note**: Always-on monthly price of the tested sizes; apps auto-pause when idle. Buckets are allocation-priced per quota and not included.

### Evidence Summary
- **Summary**: Rails pattern fixture deployed on Ample; for this guide: the app built and started with the documented commands and answered on its public HTTPS URL.
