Docker and Kubernetes are changing the way to deploy services and applications in the Linux world. What about FreeBSD? 2 years ago we presented pot, another jail abstraction framework. In time, the pot framework has developed to provide features containers-alike. The plugin interface provided by nomad (a container orchestrator), allowed us to develop a driver for pot, enabling nomad to orchestrate pot jails. In this talk, we'd like to present this FreeBSD-based ambitious alternative to Docker-Kubernetes

The talk presents a project that use pot containers to implement a CI/CD pipeline on FreeBSD. The presentation highlights the internal structure of the project, showing how jails and ZFS are used to efficiently implement a build pipeline.

The initial idea of pot was to imitate containers, like docker, but using FreeBSD technologies, like jails and ZFS. The goal was to run several "pots" on my laptop to serve my needs and, at the same time, to learn how to manage them efficiently, especially in term disk usage. Instead of using/extending existing tools, like ezjail or iocage, I decided to reinvent the wheel and to write myself a new tool. After some time, I realized that making pot more generic and available to everyone could be a good idea and that's what I intend to present. I also show some interesting use cases and, hopefully, a live demo.
