Cozystack Becomes a CNCF Sandbox Project

On February 28, members of the CNCF Technical Oversight Committee completed their voting and unanimously accepted Cozystack, a platform for building private clouds and PaaS, into the CNCF Sandbox. The project is currently undergoing the onboarding process. Let’s break down what this means in practice, what Cozystack is, and what the CNCF Sandbox represents.

What is Cozystack?

Cozystack is an open-source platform that enables the creation of a bare metal cloud for deploying proven cloud-native and open-source tools: managed Kubernetes clusters, databases as a service, applications as a service, and virtual machines based on KubeVirt (see the full list of components). Cozystack also provides a ready-made stack for observability and alerting based on Victoria Metrics, Victoria Logs, Grafana, and Alerta.

Cozystack has officially been included in the CNCF Landscape

You can now find the Cozystack open source platform in the CNCF Landscape categories of Platform and Certified Kubernetes — Installed. Despite being a relatively young platform, Cozystack is experiencing rapid growth, and an active community of developers and users has already formed around it.

Weekly open meetings are held to discuss the platform’s development, and the Telegram chat is constantly buzzing with discussions and questions. Our speakers are regularly invited to industry conferences to share their experiences with integrating and utilizing various Open Source components within the platform. For example, you can check out a recent video from the Talos Linux Install Fest and a series of articles on building your own cloud in the official Kubernetes blog.

The Cozystack project has released Talm, a configuration manager for Talos Linux

The developers of the open-source PaaS platform Cozystack have prepared the Talm project, aimed at simplifying the configuration of bare-metal servers for Talos Linux, an operating system designed to run Kubernetes with a Kubernetes-like API and configured via a single Yaml manifest. Although Talm was created to describe the declarative installation of Cozystack, it is not tied specifically to this platform and can be used to manage any Talos Linux configurations. The project is developed under the MPL license.
