The first release of the free PAAS platform cozystack based on Kubernetes has been published. The project is positioned as a complete platform for hosting providers and a framework for building private and public clouds. Cozystack is designed to be installed directly on servers and covers all aspects of infrastructure preparation to provide managed services. Users can launch and provide Kubernetes Clusters, databases, and virtual machines on demand. The platform’s code is available on GitHub and distributed under the Apache-2.0 license.
Talos Linux and Flux CDs form the basic technology stack for Cozystack. System images, core components, and necessary modules are pre-built and updated atomically to minimize moving parts and ensure stable performance.
The platform utilizes Kubevirt technology to launch virtual machines directly in Kubernetes containers. It integrates with Cluster API to deploy controlled Kubernetes Clusters within the main Kubernetes Cluster. Cozystack also includes a network factory based on Kube-OVN, Cilium for service network organization, Metallb for external service announcements, Linstor for storage repository management using ZFS as the underlying storage layer, and DRBD for replication. Additionally, there is a monitoring solution based on Victoriametrics and Grafana.
One of the key features of Cozystack is the easy installation method in an empty data center using PXE and the Debian-like installer talos-booststrap. Despite commercial interest, the project is being developed by community enthusiasts and is committed to remaining free. A request has been submitted to CNCF (Cloud National Computing Foundation) to consider transferring Cozystack
