Tue, 31 Mar 2026 00:00:00 +0000

Cozystack 1.2: OpenSearch, VPC Peering, and Smarter Tenant Scheduling

The Cozystack 1.2 release line is now available. v1.2.0 was published on March 27, 2026, and v1.2.1 followed on March 31, 2026.

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 v1.2.1 release focuses on safety and operational stability.

Main highlights

Managed OpenSearch in the application catalog

Cozystack 1.2 adds OpenSearch 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.

Cozystack v1.0 & v1.1: Introducing Package-Based Architecture, Cozystack Operator, Velero Strategy Controller, MongoDB and OpenBAO Support

Mon, 16 Mar 2026 07:30:00 +0000

Author: Timur Tukaev (Ænix)

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.

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).

Cozystack v0.41: MongoDB, Dashboard Edit Button, Resource Quota UI, JWT Security, and cert-manager Gateway API

Tue, 20 Jan 2026 00:00:00 +0000

Cozystack v0.41: MongoDB, Dashboard Edit Button, Resource Quota UI, JWT Security, and cert-manager Gateway API

Version 0.41 expands the database catalog with MongoDB and significantly improves the dashboard and security posture.

Major Features and Improvements

MongoDB as a Managed Application

MongoDB joins the Cozystack application catalog as a fully managed service with:

Replica set deployment with configurable replicas.
Persistent storage with configurable size.
Resource management (CPU and memory requests/limits).
Built-in monitoring integration.

Dashboard Edit Button

All resources in the dashboard now have an Edit button, enabling users to modify any deployed application directly from the UI without switching to the CLI.

Cozystack v0.40: LINSTOR Scheduler, SeaweedFS Traffic Locality, ValuesFrom Configuration, and Platform Decomposition

Sat, 10 Jan 2026 00:00:00 +0000

Cozystack v0.40: LINSTOR Scheduler, SeaweedFS Traffic Locality, ValuesFrom Configuration, and Platform Decomposition

Version 0.40 is a substantial release that optimizes storage performance, introduces a new configuration mechanism, and refactors the platform architecture for modularity.

Major Features and Improvements

LINSTOR Scheduler

A new LINSTOR scheduler places pods on nodes that have local storage replicas, minimizing network I/O for storage-heavy workloads. An admission webhook automatically routes pods to the optimal node. Combined with auto-diskful (converting diskless to diskful after 30 minutes of Primary state), this creates a self-optimizing storage topology.

Cozystack v0.39: Topology-Aware Routing, Windows VM Scheduling, Talm Overhaul, and VMAgent for Tenants

Tue, 23 Dec 2025 00:00:00 +0000

Cozystack v0.39: Topology-Aware Routing, Windows VM Scheduling, Talm Overhaul, and VMAgent for Tenants

Version 0.39 enhances networking, scheduling, and the tooling around Cozystack infrastructure management.

Major Features and Improvements

Topology-Aware Routing for Cilium

Cilium services now support topology-aware routing, keeping traffic local to the same zone or region when possible. This reduces latency and cross-zone network costs.

Automatic Cilium Pod Rollouts

Cilium pods now automatically roll out when their configuration changes, eliminating the need for manual restarts after config updates.

Talm v0.17: Built-in Age Encryption for Secrets Management

Wed, 17 Dec 2025 00:00:00 +0000

Talm v0.17: Built-in Age Encryption for Secrets Management

The latest release of Talm, the configuration manager for Talos Linux, introduces a powerful new feature: built-in encryption using the age encryption tool. This enhancement allows you to securely store sensitive configuration files like secrets.yaml, talosconfig, and kubeconfig in Git repositories while following security best practices.

Why Age Encryption?

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 git-crypt or external secret management systems add complexity and dependencies.

Cozystack v0.38: Virtual Private Cloud, VNC Console, Configurable Worker K8s Versions, and HTTPS Enforcement

Tue, 25 Nov 2025 00:00:00 +0000

Cozystack v0.38: Virtual Private Cloud, VNC Console, Configurable Worker K8s Versions, and HTTPS Enforcement

😜 Cozystack v0.36: Server-side Encryption for S3, Kube-OVN Cluster Health Monitor, REST API Documentation

The new version of Cozystack focuses on the stability, observability, and flexible configuration of managed applications.

👉 Major Features and Improvements

Per-Namespace Resource Limits for Tenants

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.

Cozystack v0.35:
