🗜 The CNCF webinar is now live! Andrei Kvapil: Kubernetes is the new Skynet or the rise of Kubernetes automation

https://www.youtube.com/watch?v=rBruFVdY6Fs

Kubernetes is famous as the container orchestrator—but lately, it’s becoming the orchestrator of everything. Crossplane for external resources, operators for databases, and beyond.

What if you could deploy a platform that runs itself—with minimal human intervention? In this talk, Andrei Kvapil will break down the tools making this possible:

- Talos Linux for provisioning Kubernetes on bare metal
- KubeVirt for orchestrating VMs seamlessly
- Cluster API and Kamaji for large-scale cluster management

Agenda and notes

- News: Release v0.30.0.
- GPU support.
- News: new test infrastructure from CNCF. We’re actively working on CI, and it helped us advance GPU support. We’re also able to work with ARM now.
- State of Kubernetes Certified. https://t.me/cozystack/10620
- Are there new successful deployments? Come and tell us about your Cozystack cluster. (this should be a regular topic)
- What’s your current Cozystack version and why it is what it is? It would be nice to hear both those who follow the edge and those who are several versions behind.
- Do we need out-of-the-box integration with proxmox? One community member is working on it, but in a separate branch. We can take an effort to merge it in a neat way, if there’s demand.

Open Floor:
- [kirill] tracing solution for Cozystack
- [kirill] DevSecOps
- [nbykov] gpu-operator support in Talos Linux. GPU for pods. GPU for vms
- [femi] Ever wondered if we can delete cozystack deployment and reapply it, just incase.. doing kubectl delete -f ordinarily don't work.
- [femi] changing tenant configuration should updated all components

Sergey Pronin (ex-Percona) recently published a detailed comparison in his personal blog, evaluating various solutions for running and managing databases in Kubernetes. He reviewed four platforms: KubeBlocks, KubeDB, Cozystack, and Percona Everest.

While all options focus solely on database provisioning, Cozystack stands out as the only platform enabling full-fledged cloud deployment—going beyond just databases to offer a complete, ready-to-use cloud solution.

🎥 CNCF On demand webinar: Kubernetes is the new Skynet or the rise of Kubernetes automation

Date and time:
CEST: Apr 24, 9:00 AM — Apr 25, 9:00 AM
PT: Apr 24, 12:00 AM — Apr 25, 12:00 AM

Webinar topics and agenda:
What if we had a Platform able to operate and pilot itself, with a fraction of human-based operations?

In this talk, Andrei's knowledge and developer experience will shed light on the tools being able to execute complex tasks such as installing Kubernetes on bare metal servers (Talos Linux), tools being able to satisfy all the complex conditions of orchestrating VM's (KubeVirt), till to operate Kubernetes clusters at large scale.

🚀 Supercharge Your AI/ML Workloads with GPU-Powered VMs in Cozystack!

The latest Cozystack release brings native GPU support for virtual machines, letting you run AI/ML applications on 100% open-source infrastructure. Just plug in a physical GPU to your node, and pass it through to your VM — no vendor lock-in, no compromises.

What’s next? We’re already working on:
🔹 vGPU support (fractional GPU sharing)
🔹 Tenant GPU access via K8s operator for AI workloads in multi-tenant clusters

📖 Check out the docs to get started: cozystack.io/docs/operations/virtualization/gpu

What is Cozystack
Cozystack is a free PaaS and framework for building clouds that unifies VMs, containers, and GPU workloads under Kubernetes. With KubeVirt integration, multi-tenancy, and bare-metal simplicity, it lets enterprises deploy AI, databases, or edge apps without vendor lock-in. And service providers can turn hardware into a cloud business: sell managed K8s, VMs and GPU services. CNCF Sandbox project.

We've raised

Ænix, the company behind the open-source Cozystack platform, today announced a $300,000 seed investment round by Prospective Technologies, a venture capital firm known for backing cutting-edge developer tools and early-stage tech companies, including imgproxy, Qase, and DBeaver.

This funding will fuel the growth of Cozystack, an open-source platform that simplifies the deployment and management of virtual machines, containers, databases, bare-metal applications, and AI workloads. Designed for enterprises and service providers seeking digital sovereignty, Cozystack provides modern APIs to manage on-premises hardware, enhancing security and compliance for regulated industries.

We haven’t shared much about Cozystack’s new features lately, even though we’ve released six new versions over the past month and a half: 0.24, 0.25, 0.26, 0.27, 0.28, and 0.29. Let’s take a closer look at the changes, starting from the latest release and going back to version 0.24.
