Show HN: Bocker – Docker implemented in 100 lines of bash
Using btrfs subvolumes as the image format, that's a nice touch. On the same road as the hypothetical systemd packaging system (not that I'm very enthusiastic about that).The network, PID and mount namespaces are the ones unshared, plus a private /proc.I like tools like this because they're reality checks on how the basics of Linux containers are just a few essential system calls, and particularly that they're limited.
