From bare metal to managed Kubernetes: Cozystack architecture explained

This article provides a technical transcript from a meetup in Dubai focused on the Cozystack platform. The author details the architecture of this open-source solution designed for deploying managed services on bare metal hardware. The discussion covers key system components, including Talos, Flux, LINSTOR, Kube-OVN, Cilium, KubeVirt, and Kamaji. Special attention is given to the 'Kubernetes-in-Kubernetes' concept and the separation of control plane management, compute nodes, and storage. The author explains how user resources are transformed into functional services and defines the boundary between cloud platforms and traditional virtualization. This material is valuable for DevOps engineers and architects working with Kubernetes infrastructure and the automation of cloud environments on bare metal servers.
