📌 Protofire Experience Operating Kubernetes with Cozystack
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.
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 Cozystack, primarily due to its all-in-one approach and compatibility with bare-metal infrastructure.
Cozystack is built on Talos Linux, which provides immutable and secure nodes, and includes a set of pre-packaged Helm-ready applications such as PostgreSQL, Redis, RabbitMQ, and Ingress-NGINX. These built-in components allowed us to accelerate the initial setup while maintaining flexibility for customization.
Currently, we manage two Kubernetes clusters—each composed of three control-plane and three worker nodes, with capacity planned for scaling. Based on our infrastructure modeling and cost tracking, we expect a 7× to 10× reduction in spend compared to our previous AWS setup.
During the initial phase, migrating and tuning each environment, including adapting Helm charts, took more than a day. Through iteration and process improvements, we’ve since reduced this time: today, standard environments can be provisioned and configured in roughly one day.
We also restructured our observability tooling during this process. We adopted Loki for centralized log collection, complementing the existing metrics and Grafana dashboards already available through the platform.
Cozystack’s recent joining CNCF Sandbox gave us additional reassurance regarding its long-term support and technical maturity. From our perspective, this migration has provided meaningful operational and financial benefits, and helped us simplify and standardize how we deliver and maintain services internally.

😜 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.
Kube-OVN Cluster Health Monitor
A new component called the Kube-OVN Plunger continuously monitors the health of the Kube-OVN network's central control cluster. This external agent gathers OVN cluster status and consensus information, exposing Prometheus metrics and live events stream via SSE. As a result, it provides much better visibility of the virtual network layer and helps maintain a reliable and observable network in Cozystack. This change opens the road to automated Kube-OVN database operations and recovery in specific corner cases.
Configurable CoreDNS Addon for Kubernetes
Cozystack introduces a dedicated CoreDNS addon for managing cluster DNS with greater flexibility. CoreDNS is now deployed via a Helm chart and can be tuned through custom values in the cluster specification, including autoscaling, replica count, and adjusting service IP. CoreDNS can now be configured in the dashboard and using Cozystack API.
Granular SeaweedFS Service Configuration
The SeaweedFS S3 storage service in Cozystack is now far more configurable at a component level. The Helm chart for SeaweedFS now includes independent configuration for each component and its resources. It includes the master nodes, volume servers with support for multiple zones, filers, the backing database, and the S3 gateway. Administrators can set per-component parameters such as the number of replicas, available CPU, memory, and storage size.
Server-side Encryption for S3
Cozystack v0.36.0 includes SeaweedFS 3.97, bringing support for server-side encryption of S3 buckets (SSE-C, SSE-KMS, and SSE-S3).
Breaking change: upon updating Cozystack, SeaweedFS will be updated to a newer version, and the services specification will be converted to the new format.
Custom Resource Profiles for Ingress Controller
NGINX controller is now configurable on a per-replica basis. Configurations include the ingress controller pods' CPU and memory requests/limits, either with direct values or using one of the available presets.
Built-in LLDP-Based Neighbor Discovery in Talos
Cozystack now includes the LLDPD extension in its Talos OS image, enabling Link Layer Discovery Protocol (LLDP) out of the box. This means each node can automatically discover and advertise its network neighbors and topology without any manual setup.
Use external IP for Egress Traffic in VMs
When a virtual machine has an external IP assigned to it, it will now always use it for egress traffic, independently of the external method used.
🔔 New components versions
- Update LINSTOR to v1.31.3
- Update SeaweedFS to v3.97
- Update Kube-OVN to 1.14.5
- Replace Bitnami images with alternatives in all charts
📚 New Documentation
- REST API Reference
- How to add a node to a Cozystack cluster
- Troubleshooting LINSTOR controller crash loops
- Troubleshooting LINSTOR CrashLoopBackOff related to a broken database
- Troubleshooting Piraeus custom resources
All changes: v0.36.0, v0.36.1, v0.36.2

📌📌📌 Cozystack v0.37: Brand New UI
In the new release, the Cozystack developer community unveiled a completely new UI based on the openapi-ui project. The maintainers fully rewrote the platform’s frontend, delivered numerous improvements, and fixed issues that existed in the previous Kubeapps-based UI. Let’s see what’s inside.
Cluster selector
A cluster selector has been added. Today, the dashboard operates in single-cluster mode (one dashboard per cluster). The same UI will power multi-cluster mode in future releases.
Namespace navigation (Tenant Namespace)
On the cluster view, you now see all namespaces you’re ennoscriptd to. The list is built via the Kubernetes API aggregation layer (tenant namespace), so only namespaces you have access to are shown.
Application categories
Existing applications are split into three categories. In upcoming releases, categories will be optional — you’ll be able to deploy only selected groups and skip others.
Richer resource pages
Every resource page now includes:
- a resource table and basic metadata,
- Conditions,
- Workloads (what’s currently running),
- Ingresses, Services, Secrets,
- the resource YAML.
OpenAPI-driven configurators
Resource creation uses forms auto-generated from the Kubernetes OpenAPI spec. Field definitions and validation come directly from the spec — no YAML comments needed.
Spec generation from Helm
New application specs are generated from Helm charts using the cozy-values generator. Fields you add in the form are reflected live in the resulting YAML.
Tenant administration separated
Tenant management modules have moved to a dedicated Administration section: create sub-tenants and deploy tenant-specific modules/apps there (subject to your role and permissions).
VM features groundwork
A VNC console tab for virtual machines is planned and will appear as an additional tab. Certain resource types (e.g., KubeVirt VMs) will gain specialized tabs/fields.
New Components Versions
Flux Operator 0.29.0
Cilium v1.17.8
Velero v1.17.0
openapi-ui v1.0.3
LINSTOR v1.32.3
SeaweedFS v3.99
All changes: v0.37.0, v0.37.1, v0.37.2, v0.37.3, v0.37.4

On the cluster view, you now see all namespaces you’re ennoscriptd to. The list is built via the Kubernetes API aggregation layer (tenant namespace), so only namespaces you have access to are shown.
Application categories
Existing applications are split into three categories. In upcoming releases, categories will be optional — you’ll be able to deploy only selected groups and skip others.
Richer resource pages
Every resource page now includes:
- a resource table and basic metadata,
- Conditions,
- Workloads (what’s currently running),
- Ingresses, Services, Secrets,
- the resource YAML.
OpenAPI-driven configurators
Resource creation uses forms auto-generated from the Kubernetes OpenAPI spec. Field definitions and validation come directly from the spec — no YAML comments needed.
Spec generation from Helm
New application specs are generated from Helm charts using the cozy-values generator. Fields you add in the form are reflected live in the resulting YAML.
Tenant administration separated
Tenant management modules have moved to a dedicated Administration section: create sub-tenants and deploy tenant-specific modules/apps there (subject to your role and permissions).
VM features groundwork
A VNC console tab for virtual machines is planned and will appear as an additional tab. Certain resource types (e.g., KubeVirt VMs) will gain specialized tabs/fields.

Cozystack: Build Your Own Open Source AWS On Bare Metal - Andrei Kvapil, Maintainer
Kubernetes and cloud infrastructure are the de facto standard. Many teams default to public clouds (AWS/GCP/Azure)—convenient, but not for everyone. Vendor lock-in, data control, and compliance push workloads to bare metal. i'll explain in a five minutes how Cozystack enables businesses to build open-source bare-metal infrastructure with cloud-like ease and zero vendor lock-in, while empowering service and hosting providers to compete with hyperscalers.
2. CNCF Project Pavilion: November, 11, 10:30 AM - 3:00 PM
Kiosk: 14B
Let's meet in Atlanta, November 10-13 and talk about your clouds and cloud platforms!
