HowTo: Kleene as a Container Management Platform for FreeBSD

(2025-02-14):
Kleene is a container management (jail manager) platform designed specifically for FreeBSD, bringing familiar concepts from Docker while fully embracing FreeBSDs native tools and philosophy. Instead of reinventing the wheel, Kleene follows the KISS (Keep It Simple, Stupid) principle, leveraging FreeBSD’s built-in features to simplify application deployment, maintenance, and upgrades without unnecessary complexity or abstraction. By using FreeBSD’s core technologies like jails, ZFS, and PF (Packet Filter), Kleene provides a streamlined way to build, run, and manage containerized applications while maintaining transparency and control. Key functionalities include: Jailed Applications: Running lightweight, isolated environments using ZFS for storage efficiency. Native Networking: Automatically setting up necessary network devices and configurations. Firewall Integration: Managing connectivity securely with FreeBSD’s PF firewall. Unlike some container solutions that introduce heavy layers of abstraction, Kleene stays true to FreeBSD’s “Power to Serve” motto, ensuring users retain full visibility and control over their system.

Run Linux Containers on FreeBSD 14 with Podman

(2024-10-06):
In one of my recent blog posts, I shared my journey as a long-time FreeBSD user. I talked about how I’ve been incredibly happy with the system, appreciating its rock-solid stability, flexibility, and performance. But, like every OS, FreeBSD had its gaps, especially when it came to some modern developments – one of which has been a pain point for many of us working with containerized environments: native support for Docker and Podman Linux images. Until recently, this missing functionality made working with containerized applications a bit of a challenge. Let me explain why that’s changed and how FreeBSD 14 has finally caught up to the container party. The Old Way: bhyve Linux VMs For a long time, one of the workarounds for running Linux containers on FreeBSD was to spin up a Linux VM using bhyve, FreeBSD’s native hypervisor. While bhyve is fantastic in its own right (fast, lightweight, .... [read more]
