Overview

Merge dagger.io/dagger/engine into dagger.io/dagger. The result is a single package known as the Dagger CUE API, version 0.2. It is documented below.

Dagger CUE API (0.2+)

As of Dagger 0.2 (codename Europa), the Dagger CUE API can be imported at dagger.io/dagger.

The Dagger CUE API is the set of CUE packages released alongside the Dagger engine, to allow developers to access its features.

Plan definition

#Plan defines the structure of a Dagger plan - a complete configuration executable by dagger up.

Core types

Dagger extends the CUE type system with the following core types:

are implemented by Dagger itself, and are always available.

The following core actions are available:
