How to use it?

[s1gnate-sync]

Right now executing command build is very dangerous as it deletes huge chunks of rootfs, try to run it outside of isolated rootfs and your os is ruined. How it supposed to work?

localhost:~/dockerless/alpine$ tar xvf /work/rootfs-images/alpine.edge.tar.gz .

Just on funny side it seems like very developer is doing his own "docker" :D

[ThomasK33]

Hey @s1gnate-sync, thanks for opening the issue.

Dockerless aims to run from within an isolated container, e.g., docker or another OCI-compliant runtime.
It performs all the steps specified in a Dockerfile imperatively on the rootfs without needing to have a Docker socket or build kit present.
Everything is executed just in time, and once completed, it will result in the same fs and environment as if the image was built ahead of time.
