summary
Canonical builds distroless base images by extracting files from Ubuntu packages using a new tool called chisel, keeping provenance from the Ubuntu archive while removing shells and package managers. The pipeline uses Dockerfile and scripts to produce runtime-specific “slices” and yields 4–6 MB images for self-contained .NET apps, about half the size of earlier distroless variants. Images are published to Docker Hub and MCR and are currently marked experimental.
