Cozystack has recently released version 0.33 of its workstack platform, which is built on Kubernetes. The platform aims to provide a ready-made solution for hosting providers and a framework for building private and public clouds. By installing directly on servers, Cozystack covers all aspects of infrastructure preparation to offer managed services, including launching Kubernetes clusters, databases, and virtual machines. The platform’s code is available on GitHub and distributed under the Apache-2.0 license.
Cozystack utilizes talos linux and flux cd in its technology stack. Pre-built images with the system, core, and necessary modules are updated atomarly, eliminating the need for components like DKMS and package managers for stable performance. A straightforward installation method is provided for deploying in an empty data center using PXE and the Debian-like installer talos-bootstrap. Cozystack also offers a variety of services such as KAFKA, FerretDB, PostgreSQL, CILIUM, GRAFANA, and Victoria Metrics within the platform.
Within the Cozystack platform, the network infrastructure is implemented using kube-ovn, while cilium is used to organize the service network and Metallb for service announcements. Storage is handled by linstor, which suggests using ZFS as a base layer for storage and DRBD for replication. Additionally, a monitoring stack based on Victoriametrics and Grafana is included. Virtual machines are launched using kubevirt technology, allowing for classic virtual machines to run directly in Kubernetes containers with all necessary integrations.
Recently, the project team has released versions 0.31, 0.32, and 0.33 of Cozystack, introducing various changes and improvements in each release.
