boco

Turn container images into bootable VMs

Example

FROM alpine:latest
CMD ["/bin/sh"]

# Build the container
podman build ./example/alpine -t boco-alpine

# Make the container bootable. boco injects a custom init program,
# then packs the rootfs as a qcow2 disk.
boco build qcow2 boco-alpine

# Boot the image using QEMU, and drop into /bin/sh.
boco boot boco-alpine

# Cleanup
boco image rm boco-alpine
podman image rm boco-alpine

Kernel

boco boots VMs using a shared kernel at $XDG_DATA_HOME/boco/registry/vmlinuz. Place a suitable x86 bzImage there before running boco boot.
