# Dagger CUE API
|
|
|
|
As of Dagger 0.2, the Dagger CUE API can be imported via `dagger.io/dagger` & `dagger.io/dagger/core`
|
|
|
|
The Dagger CUE API is the set of CUE packages released alongside the Dagger engine.
|
|
|
|
Developers of other Dagger packages are expected to build on top of these core packages.
|
|
|
|
### Plan definition
|
|
|
|
`#Plan` defines the structure of a Dagger plan - a complete configuration executable by `dagger do`
|
|
|
|
| Definition | File | Description |
|
|
| :-- | :-- | :-- |
|
|
| `#Plan` | [plan.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/plan.cue) | A special kind of program which `dagger` can execute |
|
|
|
|
### Core types
|
|
|
|
Dagger extends the CUE type system with the following core types:
|
|
|
|
| Definition | File | Description |
|
|
| :-- | :-- | :-- |
|
|
| `#Address` | [types.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/types.cue) | Network service address |
|
|
| `#CacheDir` | [exec.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/core/exec.cue) | A (best effort) persistent cache dir |
|
|
| `#FS` | [types.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/types.cue) | Reference to a filesystem tree |
|
|
| `#HealthCheck` | [image.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/image.cue) | Container health check |
|
|
| `#ImageConfig` | [image.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/image.cue) | Container image config |
|
|
| `#Mount` | [exec.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/core/exec.cue) | Transient filesystem mount |
|
|
| `#Ref` | [image.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/image.cue) | An address for a remote container image |
|
|
| `#Scratch` | [types.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/types.cue) | An empty directory |
|
|
| `#Secret` | [types.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/types.cue) | Secure reference to an external secret |
|
|
| `#Socket` | [types.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/types.cue) | Reference to a network socket: unix, tcp/udp or npipe |
|
|
| `#TempDir` | [exec.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/core/exec.cue) | A temporary directory for command execution |
|
|
|
|
### Core actions
|
|
|
|
Dagger works by executing actions in a certain order and passing data between actions in a certain layout.
|
|
|
|
Developers can combine actions into higher-level actions, which in turn can be combined into even higher-level actions,
|
|
and so on at arbitrary levels of depth. At the bottom of this abstraction stack are *core actions*: these
|
|
are implemented by Dagger itself, and are always available.
|
|
|
|
The following core actions are available:
|
|
|
