You guessed correctly: Dagger does not replace Github Actions, they are complementary. The Dagger project itself uses Github Actions and Dagger together :)

Sure, you can do that. The only dependency to run Dagger is Docker or any OCI-compatible runtime. So, assuming the `ubuntu-latest` runner has docker installed, you can just execute your Dagger-enabled tool, and it should work out of the box.

For example here's our own github workflow for testing the Python SDK (you can look around for other workflows): https://github.com/dagger/dagger/blob/main/.github/workflows...

Note that the word "dagger" doesn't even appear, since Dagger is embedded as a library (in this case, using the Go SDK). As far as GHA is concerned, it's just executing a regular binary.
