🔥🔥🔥 The Open Source Platform Cozystack Version 0.16.0 Released: Alert System with Telegram Notifications and More Improvements

Key Highlights Cozystack now features an alert system based on the open-source tool Alerta, with the ability to configure notifications directly to Telegram. Additionally, you can receive alerts from k8s-prometheus stack, all Grafana dashboards have been updated, as well as Grafana itself and the grafana-operator.

Other changes:
- Nginx-ingress updated to version v1.11.2 and issue with accessing nginx-ingress from inside the cluster was resolved
- Flux and flux-operator updated to the latest versions
- Updated Kamaji to the latest version and fixed issue with controller restarts
- Added endpointslice controller to CCM; ordered services now send traffic only to nodes that serve them
- Talos Linux updated to version v1.8.0
- Cilium updated to the latest patch version (v1.16.2)

What’s New in Cozystack v0.17: Windows on VMs, VM image upload app, and web interface for S3 buckets

Virtualization Enhancements
The old Virtual Machine app has been split into two separate apps: vm-disk and vm-instance.

vm-disk (Virtual Machine Disk) has been separated from the virtual machine application, now supporting image uploads from HTTP or local sources. When creating a disk, you can specify the source and type of image—CD-ROM or classic.

vm-instance (Virtual Machine Instance) allows you to launch a virtual machine from created disks.

This new structure enables the creation of virtual machines with multiple disks, installation from CD-ROMs, and the ability to switch disks between different VMs. This approach allows for more flexible disk and virtual machine configuration management.

The old Virtual Machine app has been retained for compatibility and to offer a simpler way of launching virtual machines in Cozystack.

InstanceType and InstanceProfile Options
New instanceType and instanceProfile options have been added, along with a default set of instances and profiles for Ubuntu, RHEL, Alpine, and Windows. You can now configure virtual machines with optimal parameters (e.g., enable TPM, use virtio devices, or tablet-pointer) depending on the operating system. Instead of manually specifying resources for a VM, you can use standardized instances designed for specific workloads.

These instance types also extend to Kubernetes, allowing for better planning of your node groups.

CDI Upload Proxy
An option for enabling proxying for image uploads from local machines has been added to the ingress, and the CDI (Containerized Data Importer) has been updated for better compatibility with block devices. Previously, image uploads for LINSTOR using the virtctl utility were unavailable, but we have resolved this issue and contributed a patch upstream to LINSTOR.

Windows Virtual Machine Support
With the new vm-disk and vm-instance features, we tested the installation of Windows 10 and Windows Server 2025 from ISO, followed by switching to VirtIO drivers. Everything works smoothly.

Web Interface for S3 Buckets
When ordering S3 buckets, a web interface is now automatically deployed for accessing them. You can upload and delete files, as well as generate temporary links for public access.

This interface is built on s3manager (Apache 2.0).

Alert System Improvements
New alerts for FluxCD have been added, providing real-time status updates on releases. Alerts are now more structured and categorized, making it easier to navigate and identify issues. Additionally, the Resource field now displays the specific problematic resource, allowing for faster troubleshooting and resolution.

Telegram Alert Integration
A new feature allows the delivery of alerts directly to Telegram, including deduplication to prevent alert spam. Alerts now come with actionable buttons, enabling you to manage the lifecycle of each alert (e.g., acknowledge, resolve) directly within the Telegram interface.
