&lt;p&gt;hello, world! We are the team behind 
&lt;a href="https://cozystack.io" target="_blank"&gt;Cozystack&lt;/a&gt;, an open-source platform for building clouds on your own hardware. We want to explain why we decided to target the game server space and what came of it.&lt;/p&gt;
&lt;p&gt;&lt;img src="https://deploy-preview-470--cozystack.netlify.app/blog/2026/04/game-servers-on-cozystack-no-april-fools-joke/cozystack-dashboard-game-servers-marketplace.png" alt="Cozystack dashboard showing a marketplace of managed game servers"&gt;&lt;/p&gt;
&lt;h2 id="what-is-cozystack"&gt;What Is Cozystack&lt;/h2&gt;
&lt;p&gt;Cozystack is a platform that turns ordinary servers into a full-fledged cloud. The project is part of CNCF Sandbox, is distributed under the Apache 2.0 license, and is deployed on bare-metal servers.&lt;/p&gt;</description></item><item><title>Cozystack 1.2: OpenSearch, VPC Peering, and Smarter Tenant Scheduling</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2026/03/cozystack-1-2-opensearch-vpc-peering-and-smarter-tenant-scheduling/</link><pubDate>Tue, 31 Mar 2026 00:00:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2026/03/cozystack-1-2-opensearch-vpc-peering-and-smarter-tenant-scheduling/</guid><description>&lt;h3 id="cozystack-12-opensearch-vpc-peering-and-smarter-tenant-scheduling"&gt;Cozystack 1.2: OpenSearch, VPC Peering, and Smarter Tenant Scheduling&lt;/h3&gt;
&lt;p&gt;The Cozystack 1.2 release line is now available. 
&lt;a href="https://github.com/cozystack/cozystack/releases/tag/v1.2.0" target="_blank"&gt;v1.2.0&lt;/a&gt; was published on March 27, 2026, and 
&lt;a href="https://github.com/cozystack/cozystack/releases/tag/v1.2.1" target="_blank"&gt;v1.2.1&lt;/a&gt; followed on March 31, 2026.&lt;/p&gt;
&lt;p&gt;This cycle expands the platform in three important directions: managed search and analytics, secure networking between tenant environments, and better control over where tenant workloads run. The follow-up &lt;code&gt;v1.2.1&lt;/code&gt; release focuses on safety and operational stability.&lt;/p&gt;
&lt;h3 id="main-highlights"&gt;Main highlights&lt;/h3&gt;
&lt;h4 id="managed-opensearch-in-the-application-catalog"&gt;Managed OpenSearch in the application catalog&lt;/h4&gt;
&lt;p&gt;Cozystack 1.2 adds &lt;strong&gt;OpenSearch&lt;/strong&gt; as a fully managed service. It supports OpenSearch v1, v2, and v3, can run in a multi-role topology, enables TLS by default, ships with built-in HTTP Basic authentication, and can optionally deploy OpenSearch Dashboards alongside the engine.&lt;/p&gt;</description></item><item><title>Cozystack v1.0 &amp; v1.1: Introducing Package-Based Architecture, Cozystack Operator, Velero Strategy Controller, MongoDB and OpenBAO Support</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2026/03/cozystack-1-0-release/</link><pubDate>Mon, 16 Mar 2026 07:30:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2026/03/cozystack-1-0-release/</guid><description>&lt;p&gt;&lt;strong&gt;Author&lt;/strong&gt;: Timur Tukaev (Ænix)&lt;/p&gt;
&lt;p&gt;The last platform release was 0.41. So it came as a surprise when the next release, 0.42, turned out to be the answer to the ultimate question of life, the universe, and everything. The number of serious changes that had piled up was just too great—so much so that 0.42 had to be renamed to 1.0.&lt;/p&gt;
&lt;p&gt;With the release of v1.0.0, Cozystack is undergoing a fundamental architectural transition. We’ve built a package system based on FluxCD and OCI artifacts — think of it like apt for Debian/Ubuntu, but made for Kubernetes (see “Package-based Deployment” below). This let us introduce a unique new approach: Build Your Own Platform (BYOP).&lt;/p&gt;</description></item><item><title>Cozystack at KubeCon Europe 2026</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2026/03/cozystack-at-kubecon-amsterdam-26/</link><pubDate>Wed, 11 Mar 2026 00:00:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2026/03/cozystack-at-kubecon-amsterdam-26/</guid><description>&lt;p&gt;&lt;strong&gt;Author&lt;/strong&gt;: Timur Tukaev (Ænix)&lt;/p&gt;

&lt;p&gt;The latest release of 
&lt;a href="https://github.com/cozystack/talm" target="_blank"&gt;Talm&lt;/a&gt;, the configuration manager for Talos Linux, introduces a powerful new feature: built-in encryption using the 
&lt;a href="https://age-encryption.org/" target="_blank"&gt;age&lt;/a&gt; encryption tool. This enhancement allows you to securely store sensitive configuration files like &lt;code&gt;secrets.yaml&lt;/code&gt;, &lt;code&gt;talosconfig&lt;/code&gt;, and &lt;code&gt;kubeconfig&lt;/code&gt; in Git repositories while following security best practices.&lt;/p&gt;
&lt;p&gt;&lt;img src="https://cdn-images-1.medium.com/max/800/0*encryption.png" alt=""&gt;&lt;/p&gt;
&lt;h3 id="why-age-encryption"&gt;Why Age Encryption?&lt;/h3&gt;
&lt;p&gt;Managing secrets in Git repositories has always been a challenge. While storing configuration files in version control is convenient for GitOps workflows, sensitive data like API keys, certificates, and cluster credentials should never be committed in plain text. Traditional solutions like &lt;code&gt;git-crypt&lt;/code&gt; or external secret management systems add complexity and dependencies.&lt;/p&gt;</description></item><item><title>Flux-aio, Kubernetes mTLS and the Chicken and Egg Problem</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2025/12/flux-aio-kubernetes-mtls-and-the-chicken-and-egg-problem/</link><pubDate>Fri, 12 Dec 2025 00:00:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2025/12/flux-aio-kubernetes-mtls-and-the-chicken-and-egg-problem/</guid><description>&lt;p&gt;&lt;img src="https://deploy-preview-470--cozystack.netlify.app/blog/2025/12/flux-aio-kubernetes-mtls-and-the-chicken-and-egg-problem/chicken-and-egg-problem.png" alt=""&gt;&lt;/p&gt;
&lt;p&gt;Here at 
&lt;a href="https://cozystack.io/" target="_blank"&gt;Cozystack&lt;/a&gt;, we&amp;rsquo;re once again solving the chicken-and-egg problem: how to deploy CNI and kube-proxy through Flux, while ensuring Flux itself works without CNI and kube-proxy.&lt;/p&gt;
&lt;p&gt;Flux can be started without CNI and kube-proxy using the 
&lt;a href="https://github.com/stefanprodan/flux-aio" target="_blank"&gt;flux-aio&lt;/a&gt; project (by the creator of Flux), which runs a single deployment with all controllers configured to communicate with each other via localhost.&lt;/p&gt;
&lt;p&gt;The specific challenge for Cozystack is that we deploy a small HTTP server with Helm charts and other assets used in the platform to each cluster. Flux reads these charts and installs them into the system.&lt;/p&gt;</description></item><item><title>CozySummit lineup is out!</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2025/10/cozysummit-lineup-is-out/</link><pubDate>Tue, 14 Oct 2025 00:00:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2025/10/cozysummit-lineup-is-out/</guid><description>&lt;h3 id="-cozysummit-lineup-isout"&gt;👻 CozySummit lineup is out!&lt;/h3&gt;

&lt;p&gt;Resource management for Cozystack tenants has received a final patch and is now graduated to a stable feature. Platform administrators can define explicit CPU, memory, and storage limits for each tenant’s namespace via the tenant specification. This prevents any single tenant from consuming more than their share of cluster resources, ensuring cluster stability and a guaranteed service level for each tenant.&lt;/p&gt;</description></item><item><title>Protofire Experience Operating Kubernetes with Cozystack</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2025/09/protofire-experience-operating-kubernetes-with-cozystack/</link><pubDate>Wed, 10 Sep 2025 00:00:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2025/09/protofire-experience-operating-kubernetes-with-cozystack/</guid><description>&lt;h3 id="protofire-experience-operating-kubernetes-with-cozystack"&gt;

&lt;p&gt;In a recent infrastructure transition that spanned several months, our team explored alternative container orchestration platforms to simplify operations and optimize costs. At the time, our environment consisted of nearly a hundred AWS accounts running multiple ECS services, along with managed PostgreSQL, Redis, RabbitMQ, and ALBs.&lt;/p&gt;
&lt;p&gt;One of the goals was to consolidate our deployment architecture under Kubernetes while maintaining support for stateful services, without introducing significant operational complexity. After evaluating different options, we decided to adopt 
&lt;a href="http://cozystack.io" target="_blank"&gt;Cozystack&lt;/a&gt;, primarily due to its all-in-one approach and compatibility with bare-metal infrastructure.&lt;/p&gt;</description></item><item><title>New CNCF Webinar: Building Your Own Cloud Platform with Open Source</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2025/09/new-cncf-webinar-building-your-own-cloud-platform-with-open-source/</link><pubDate>Fri, 05 Sep 2025 00:00:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2025/09/new-cncf-webinar-building-your-own-cloud-platform-with-open-source/</guid><description>&lt;h3 id="new-cncf-webinar-building-your-own-cloud-platform-with-opensource"&gt;New CNCF Webinar: Building Your Own Cloud Platform with Open Source&lt;/h3&gt;

&lt;p&gt;The new version of Cozystack takes a major step forward in its modular (or: decomposed) architecture, enabling users to swiftly integrate custom applications and services. This significantly extends the platform’s out-of-the-box functionality to meet specific business needs. And there’s more!&lt;/p&gt;

&lt;p&gt;What is Cozystack?&lt;/p&gt;
&lt;/blockquote&gt;
&lt;blockquote&gt;
&lt;p&gt;Cozystack is a free PaaS and framework for building clouds that unifies VMs, containers, and GPU workloads under Kubernetes. Companies can turn hardware into a cloud: offer users or customers managed K8s, VMs, managed data bases, applications and GPU services. With KubeVirt integration, multi-tenancy, and bare-metal simplicity, it lets enterprises deploy AI, databases, or edge apps without vendor lock-in. Cozystack is a CNCF Sandbox project.&lt;/p&gt;</description></item><item><title>Invitation to CozySummit Virtual — December 3</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2025/08/invitation-to-cozysummit-virtual--december-3/</link><pubDate>Thu, 14 Aug 2025 00:00:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2025/08/invitation-to-cozysummit-virtual--december-3/</guid><description>&lt;h3 id="invitation-to-cozysummit-virtualdecember3"&gt;Invitation to CozySummit Virtual — December 3&lt;/h3&gt;

&lt;p&gt;Talos Linux is a specialized operating system designed for running Kubernetes. In my opinion, it does that task better than others. First and foremost it handles full lifecycle management for Kubernetes control-plane components.&lt;/p&gt;
&lt;p&gt;On the other hand, Talos Linux focuses on security, minimizing the user’s ability to influence the system. A distinctive feature of this OS is the near-complete absence of executables, including the absence of a shell and the inability to log in via SSH. All configuration of Talos Linux is done through a Kubernetes-like API.&lt;/p&gt;</description></item><item><title>Cozystack Now Offers GPU Passthrough for AI/ML Virtual Machines</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2025/04/cozystack-now-offers-gpu-passthrough-for-ai-ml-virtual-machines/</link><pubDate>Fri, 18 Apr 2025 00:00:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2025/04/cozystack-now-offers-gpu-passthrough-for-ai-ml-virtual-machines/</guid><description>&lt;h3 id="cozystack-now-offers-gpu-passthrough-for-aiml-virtualmachines"&gt;&lt;strong&gt;Cozystack Now Offers GPU Passthrough for AI/ML Virtual Machines&lt;/strong&gt;&lt;/h3&gt;
&lt;p&gt;The open-source cloud platform has introduced direct GPU passthrough in its latest release, enabling users to accelerate AI, machine learning, and other compute-intensive workloads on virtual machines. By leveraging physical GPUs from host nodes, teams can now deploy open-source AI stacks without proprietary cloud dependencies.&lt;/p&gt;
&lt;p&gt;&lt;img src="https://cdn-images-1.medium.com/max/800/1*Z4hqqFhepCzEwJn7WZpJQw.png" alt=""&gt;&lt;/p&gt;

&lt;h3 id="what-is-cozystack"&gt;What is Cozystack?&lt;/h3&gt;
&lt;p&gt;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 
&lt;a href="https://cozystack.io/docs/components/" target="_blank"&gt;full list of components&lt;/a&gt;). Cozystack also provides a ready-made stack for observability and alerting based on Victoria Metrics, Victoria Logs, Grafana, and Alerta.&lt;/p&gt;</description></item><item><title>Cozystack v0.22 Release: telemetry, patched Talos v1.9.1, new entities Workload and WorkloadMonitor</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2025/01/cozystack-v0-22-release-telemetry-patched-talos-v1-9-1-new-entities-workload-and-workloadmonitor/</link><pubDate>Fri, 17 Jan 2025 00:00:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2025/01/cozystack-v0-22-release-telemetry-patched-talos-v1-9-1-new-entities-workload-and-workloadmonitor/</guid><description>&lt;h3 id="cozystack-v022-release-telemetry-patched-talos-v191-new-entities-workload-and-workloadmonitor"&gt;Cozystack v0.22 Release: telemetry, patched Talos v1.9.1, new entities Workload and WorkloadMonitor&lt;/h3&gt;
&lt;h3 id="main-changes"&gt;Main changes&lt;/h3&gt;
&lt;p&gt;In the latest release was added cozystack-controller and new entities: Workload and WorkloadMonitor, which allow monitoring the state of pods managed by operators and evaluating the service level according to predefined rules.&lt;/p&gt;
&lt;p&gt;Since different applications in Cozystack are managed by different operators, we decided to create a unified format for displaying the status of each service.&lt;/p&gt;</description></item><item><title>Introducing the Pre-New Year Release of open source platform Cozystack v0.21:</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2024/12/introducing-the-pre-new-year-release-of-open-source-platform-cozystack-v0-21/</link><pubDate>Sat, 28 Dec 2024 00:00:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2024/12/introducing-the-pre-new-year-release-of-open-source-platform-cozystack-v0-21/</guid><description>&lt;h3 id="introducing-the-pre-new-year-release-of-open-source-platform-cozystack-v021-new-user-dashboard-talos-linuxetc"&gt;Introducing the Pre-New Year Release of open source platform Cozystack v0.21: New User Dashboard, Talos Linux, etc.&lt;/h3&gt;
&lt;p&gt;The dashboard now works directly with the Cozystack API instead of relying on FluxCD resources. This enhancement enables the platform to provide a user-friendly graphical interface while integrating with Kubernetes’ standard RBAC model for managing deployment permissions.&lt;/p&gt;
&lt;p&gt;&lt;img src="https://cdn-images-1.medium.com/max/800/1*O0OQMDGX0oHS2AXm0zDg4g.png" alt=""&gt;&lt;/p&gt;
&lt;p&gt;Each tenant now includes four default groups:&lt;br&gt;

&lt;ul&gt;
&lt;li&gt;Kube-OVN updated to the latest stable release.&lt;/li&gt;
&lt;li&gt;Improved logic in KubeVirt CCM, delivering more reliable load balancers for tenant Kubernetes clusters.&lt;/li&gt;
&lt;li&gt;Resolved user permissions issues in OIDC.&lt;/li&gt;
&lt;li&gt;Added a dedicated cluster admin group.&lt;/li&gt;

&lt;p&gt;Hi there! I’m Andrei Kvapil, but you might know me as 
&lt;a href="https://github.com/kvaps" target="_blank"&gt;@kvaps&lt;/a&gt; in communities dedicated to Kubernetes and cloud-native tools. In this article, I want to share how we implemented our own extension api-server in the open-source PaaS platform, Cozystack.&lt;/p&gt;
&lt;p&gt;Kubernetes truly amazes me with its powerful extensibility features. You’re probably already familiar with the 
&lt;a href="https://kubernetes.io/docs/concepts/architecture/controller/" target="_blank"&gt;controller&lt;/a&gt; concept and frameworks like 
&lt;a href="https://book.kubebuilder.io/" target="_blank"&gt;kubebuilder&lt;/a&gt; and 
&lt;a href="https://sdk.operatorframework.io/" target="_blank"&gt;operator-sdk&lt;/a&gt; that help you implement it. In a nutshell, they allow you to extend your Kubernetes cluster by defining custom resources (CRDs) and writing additional controllers that handle your business logic for reconciling and managing these kinds of resources. This approach is well-documented, with a wealth of information available online on how to develop your own operators.&lt;/p&gt;</description></item><item><title>Cozystack v0.18</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2024/11/cozystack-v0-18/</link><pubDate>Thu, 07 Nov 2024 00:00:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2024/11/cozystack-v0-18/</guid><description>&lt;h3 id="cozystack-v018-release-public-api-server-metrics-and-logs-from-tenant-clusters-and-other-improvements"&gt;Cozystack v0.18 Release: Public API Server, Metrics and Logs from Tenant Clusters, and Other Improvements&lt;/h3&gt;
&lt;h3 id="-public-api-for-cozystack"&gt;🔥 Public API for Cozystack&lt;/h3&gt;
&lt;p&gt;This is the biggest and most anticipated update for us. Cozystack now includes its own Kubernetes API server, which automatically translates all requests to custom resources into HelmReleases.&lt;/p&gt;
&lt;p&gt;This means that platform administrators can now provide users with granular access to specific resources (Kuberneteses, VirtualMachines, Postgresses, etc.). Additionally, the API server can be easily extended with additional components by simply listing them in a ConfigMap — no recompilation required.&lt;/p&gt;</description></item><item><title>What’s New in Cozystack v0.17</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2024/10/what-s-new-in-cozystack-v0-17/</link><pubDate>Thu, 24 Oct 2024 00:00:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2024/10/what-s-new-in-cozystack-v0-17/</guid><description>&lt;h3 id="whats-new-in-cozystack-v017-windows-on-vms-vm-image-upload-app-and-web-interface-for-s3buckets"&gt;What’s New in Cozystack v0.17: Windows on VMs, VM image upload app, and web interface for S3 buckets&lt;/h3&gt;

&lt;p&gt;The Cozystack project has released Talm, a configuration manager for Talos Linux&lt;/p&gt;
&lt;p&gt;The developers of the open-source PaaS platform 
&lt;a href="https://cozystack.io/" target="_blank"&gt;Cozystack&lt;/a&gt; have prepared the 
&lt;a href="https://github.com/cozystack/talm" target="_blank"&gt;Talm&lt;/a&gt; project, aimed at simplifying the configuration of bare-metal servers for 
&lt;a href="https://www.talos.dev/" target="_blank"&gt;Talos Linux&lt;/a&gt;, 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.&lt;/p&gt;</description></item><item><title>DIY: Create Your Own Cloud with Kubernetes (Part 3)</title><link>https://deploy-preview-470--cozystack.netlify.app/blog/2024/04/diy-create-your-own-cloud-with-kubernetes-part-3/</link><pubDate>Fri, 05 Apr 2024 07:40:00 +0000</pubDate><guid>https://deploy-preview-470--cozystack.netlify.app/blog/2024/04/diy-create-your-own-cloud-with-kubernetes-part-3/</guid><description>&lt;p&gt;&lt;strong&gt;Author&lt;/strong&gt;: Andrei Kvapil (Ænix)&lt;/p&gt;

&lt;p&gt;Not so far ago, I was faced with a quite unusual task of configuring routing for MetalLB. All would be nothing, since MetalLB usually does not require any additional configuration from user side, but in our case there is a fairly large cluster with a quite simple network configuration.&lt;/p&gt;
&lt;p&gt;In this article I will show you how to configure source-based and policy-based routing for the external network on your cluster.&lt;/p&gt;</description></item></channel></rss>
