Europa Universe
About this directory
europa-universe/ is a staging area for the upcoming universe.dagger.io package namespace,
which will be shipped as part of the Europa release.
What is Universe?
The Dagger Universe is a catalog of reusable Cue packages, curated by Dagger but possibly authored by third parties. Most packages in Universe contain reusable actions; some may also contain entire configuration templates.
The import domain for Universe will be universe.dagger.io. It will deprecate the current domain alpha.dagger.io.
Where is the dagger package?
Europa will also introduce a new package for the Dagger Core API: dagger.io/dagger.
This is a core package, and is not part of Universe (note the import domain).
The development version of the Europa core API can be imported as alpha.dagger.io/europa/dagger.
Where is the dagger/engine package?
Europa will also introduce a new package for the Low-Level Dagger Engine API : dagger.io/dagger/engine.
This is a core package, and is not part of Universe (note the import domain).
The development version of the Europa Low-Level Engine API can be imported as either:
- alpha.dagger.io/europa/dagger/engine/spec/engine for the full spec
- alpha.dagger.io/dagger/europa/engine for the implemented subset of the spec
Universe vs other packages
This table compares Dagger core packages, Dagger Universe packages, and the overall CUE package ecosystem.
| Dagger core | Dagger Universe | CUE ecosystem | |
|---|---|---|---|
| Import path | dagger.io |
universe.dagger.io |
Everything else |
| Purpose | Access core Dagger features | Safely reuse code from the Dagger community | Reuse any CUE code from anyone |
| Author | Dagger team | Dagger community, curated by Dagger | Anyone |
| Release cycle | Released with Dagger engine | Released continuously | No release cycle |
| Size | Small | Large | Very large |
| Growth rate | Grows slowly, with engine features | Grows fast, with Dagger community | Grows even faster, with CUE ecosystem |
Notable packages
Docker API
Import path: universe.dagger.io/docker
The docker package is a native Cue API for Docker. You can use it to build, run, push and pull Docker containers directly from Cue.
The Dagger container API defines the following types:
#Image: a container image#Run: run a command in a container#Push: upload an image to a repository#Pull: download an image from a repository#Build: build an image
Examples
Import path: universe.dagger.io/examples
This package contains examples of complete Dagger configurations, including the result of following tutorials in the documentations.
For example, the todoapp example corresponds to the Getting Started tutorial
TODO LIST
- Support native language dev in
docker.#Runwith good DX (Python, Go, Typescript etc.) - Coding style. When to use verbs vs. nouns?
- Easy file injection API (
container.#Image.files?) - Use file injection instead of inline for
#Command.script(to avoid hitting arg character limits) - Organize universe packages in sub-categories?
