This looks excellent, and very fun to play with!

I used this one-liner to run an instance directly from remote source:

  dagger -c 'git https://github.com/onkernel/kernel-images | head | tree | docker-build --dockerfile containers/docker/Dockerfile | up --ports 8501:8501,8080:8080,6080:6080,9222:9222'

Be aware that the initial docker build is quite long... But caching kicks in for subsequent runs.

I look forward to playing with this!
