dagger up

The third standard workflow verb, joining dagger check and dagger generate. One command starts all services in your workspace — discovered automatically, started in parallel, ports tunneled to your host.

Annotate any function that returns a Service with +up, and dagger up discovers it across your workspace — including services from your dependencies. Port collisions are caught before anything starts, and container health checks gate readiness automatically. No YAML, no separate orchestration layer — just functions in your modules, composed through the same engine that runs your builds and tests.
