Bocker

Docker implemented in 100 lines of bash.

Prerequisites

The following packages are needed to run bocker.

  • util-linux >= 2.25.2
  • btrfs-progs

Because most distributions do not ship a new enough version of util-linux you will probably need grab the sources from here and compile it yourself.

Additionally /var/bocker needs to be on a btrfs filesystem.

For ease of use a Vagrantfile is included which will build the needed environment.

Example Usage

$ ./bocker init base-image/

$ ./bocker images
