Focker is a FreeBSD image orchestration tool in the vein of Docker. Focker leverages ZFS and Jails to natively provide powerful containerization primitives (images, volumes and containers) first introduced by the Docker platform without taking up the significantly more challenging task of achieving Docker compatibility. This has never been and never will be the goal of Focker which allows it to remain a lightweight tool with minimal dependencies and highly maintainable codebase. At the same time, the image building paradigm based on checksummed steps/layers and flexible composition builder offer significant time savings for pragmatic FreeBSD sysadmins. You can download Focker directly from GitHub or install using pip from PyPi.
