Dagger Types Reference
Dagger Types are primitives that hold internal references to values stored in the Dagger Engine. They extend the CUE type system and can be used in Dagger Actions. Their definitions can be imported from the dagger.io/dagger package.
The following types are available:
| Definition | File | Description |
|---|---|---|
#FS | types.cue | Reference to a filesystem tree |
#Secret | types.cue | Secure reference to an external secret |
#Socket | types.cue | Reference to a network socket: unix or npipe |
And there's a special instance of a Dagger Type:
| Definition | File | Type | Description |
|---|---|---|---|
#Scratch | values.cue | #FS | An empty filesystem tree |
Data structures
There's also some data structures that are tightly coupled to core actions. Their definitions are in the dagger.io/dagger/core package.
Related to mounts
| Definition | File | Description |
|---|---|---|
#Mount | core/exec.cue | Transient filesystem mount |
#CacheDir | core/exec.cue | A (best effort) persistent cache dir |
#TempDir | core/exec.cue | A temporary directory for command execution |
Related to container images
| Definition | File | Description |
|---|---|---|
#ImageConfig | core/image.cue | Container image config |
#HealthCheck | core/image.cue | Container health check |
