bunny

bunny is a build tool that makes packaging unikernels and libOSes as easy as building containers. It accepts either a YAML-based bunnyfile or standard Containerfile/Dockerfile syntax, and produces OCI images with the annotations and metadata required to run them with urunc. bunny can run as a BuildKit frontend (so docker build just works) or locally via buildctl, and supports multiple unikernel frameworks and rootfs formats including initrd, block, and raw.
