🔥Another CozySummit Virtual 2026 speaker worth your attention.
⚡𝐒𝐢𝐦𝐨𝐧 𝐊𝐨𝐮𝐝𝐢𝐣𝐬 — Founder and Engineer at ConfigButler — will present: “𝐖𝐡𝐚𝐭 𝐈𝐟 𝐄𝐯𝐞𝐫𝐲 𝐂𝐨𝐳𝐲𝐬𝐭𝐚𝐜𝐤 𝐂𝐡𝐚𝐧𝐠𝐞 𝐁𝐞𝐜𝐚𝐦𝐞 𝐚 𝐂𝐨𝐦𝐦𝐢𝐭?”
💪The idea: instead of Git driving the platform, the platform continuously writes its intent back to Git. Automatic. Silent. A durable, readable history of everything that happened — without changing how operators work.
Simon calls it Reverse GitOps. He’s building a real implementation at github.com/ConfigButler/gitops-reverser, and Cozystack’s platform-oriented Kubernetes API turns out to be a natural fit for the pattern.
If auditability and infrastructure history matter to your team — this talk is worth an hour of your time.

🔥Another CozySummit Virtual 2026 speaker worth your attention.
⚡Robert Galik — Senior Architect, founder of beby.cloud, and educator at Košická akadémia softvérového vývoja — will present: “Building a Sustainable Edge PaaS for Education: The BeBy.cloud Journey with Cozystack.”
💡The premise: students with no IT background, a low-energy edge cluster, and a full-stack Cozystack environment instead of a public cloud sandbox. No AWS bill. No abstraction layers hiding what’s actually happening. Just Kubernetes — the way it works in production at Deutsche Telekom, Siemens Healthineers, and AT&T.
Robert will show real stories of students going from zero to cloud-ready — and why a private edge cloud turns out to be a better learning environment than any managed service.
If you’re thinking about talent pipelines, cloud-native education, or what “pure Kubernetes” actually means as a foundation — this talk is for you.

Timur Tukaev, our COO, will be speaking at DevOpsDays Tashkent 2026 on May 15.
His talk: “How to Become a CNCF Project.”
It is not a theoretical overview. Cozystack was rejected the first time.
The application was weak, the story wasn’t clear, and the TOC wasn’t convinced. Two months later, our team spent a month studying successful applications, reading comments on failed ones and rewriting the narrative from the very begining.
The second application got Cozystack into CNCF Sandbox.
The talk covers what actually matters in a Sandbox application, how to talk to TAG and TOC, what signals show a project is ready and why joining a foundation like CNCF can be a growth strategy, not a bureaucratic detour.
May 15. Tashkent.

✨Another CozySummit Virtual 2026 speaker worth your attention.
Lu Servén Marín — SRE at AuthZed, maintainer of Thanos, Kilo, and various Prometheus community projects — will present: “Building a Multi-Cloud Service Mesh from the Ground Up with Kilo.”
The talk goes bottom-up: Kubernetes networking fundamentals, then what it actually takes to connect containers across nodes, geographic locations, and clusters using WireGuard and Kilo as the network fabric. From there, Lu builds a service mesh incrementally — static mesh first, then service discovery, then automated service mirroring.
No hand-waving. The talk also covers the challenges, limitations, and alternatives — which is usually the part that's most useful.

Cozystack vs OpenStack: An Honest Comparison for 2026
🧐 OpenStack has been the default answer to “how do we build a private cloud?” for over a decade — broad feature set, massive vendor ecosystem, first-mover gravity.
🤓 But a growing number of teams are discovering that operating OpenStack is a full-time job in itself.
🤯 Configuration drift across dozens of interacting services, painful upgrades that block entire sprints, and a hiring pool that shrinks as engineers gravitate toward Kubernetes-native tooling.

🚀 Ænix x WHMCS — turn your hosting panel into a modern cloud
We've built a WHMCS integration that plugs Cozystack straight into the billing panel you already run. Your customers order, you bill, Cozystack provisions — no separate control plane, no rip-and-replace.
⚙️ What your customers can now self-serve from WHMCS:
• Kubernetes clusters — managed, multi-tenant
• Managed databases — PostgreSQL, MySQL, Redis, Kafka, ClickHouse, RabbitMQ, NATS
• Virtual machines — KubeVirt-based, Linux & Windows
• Message brokers & queues
• S3-compatible object storage
• GPU workloads — for AI/ML and rendering
All provisioned, metered and invoiced through your WHMCS billing.
💸 Why it matters
If you run a hosting business or a cloud on WHMCS, you can now add a full catalog of modern, in-demand services to your offering in days — not quarters — and open new revenue lines without leaving the panel your team already knows. New services, same billing, more margin.
We also help hosters and clouds:
• migrate workloads off other hosting panels, OpenStack, VMware and legacy stacks
• integrate Cozystack + billing with other control panels
• package and add the specific apps and services your customers ask for
Especially if you're already on WHMCS — this is the fastest way to start selling Kubernetes, databases, VMs and GPU, and earn more from the customers you already have.

Cozystack uses LINSTOR + DRBD for replicated block storage. DRBD replicates at the block device level — below the filesystem, below the database, below everything. It's been battle-tested in Linux HA setups for over two decades. LINSTOR adds the Kubernetes-native orchestration layer on top.
⚙ How It Works
1. DRBD (Distributed Replicated Block Device) synchronously mirrors block devices between nodes. Every write to Node A is immediately written to Node B before the application gets an acknowledgment.
2. LINSTOR manages DRBD resources as Kubernetes StorageClasses. When a PVC requests storage, LINSTOR creates a DRBD volume, selects replica nodes, and handles the lifecycle.
3. CSI Driver exposes LINSTOR volumes as standard Kubernetes PersistentVolumes.

#Cozystack #LINSTOR #DRBD #Kubernetes #CloudNative #BareMetal #PrivateCloud #Storage
Every bare-metal operator's nightmare: a disk fails at 3 AM. If your storage is node-local (a
local-path or hostPath volume pinned to one node), you're restoring from backup and praying it's recent. Ceph gives you replication but demands 3+ dedicated storage nodes, a PhD in CRUSH maps, and constant tuning. Most teams either over-invest in storage infrastructure or under-invest and pay the price in outages.Cozystack uses LINSTOR + DRBD for replicated block storage. DRBD replicates at the block device level — below the filesystem, below the database, below everything. It's been battle-tested in Linux HA setups for over two decades. LINSTOR adds the Kubernetes-native orchestration layer on top.
⚙ How It Works
1. DRBD (Distributed Replicated Block Device) synchronously mirrors block devices between nodes. Every write to Node A is immediately written to Node B before the application gets an acknowledgment.
2. LINSTOR manages DRBD resources as Kubernetes StorageClasses. When a PVC requests storage, LINSTOR creates a DRBD volume, selects replica nodes, and handles the lifecycle.
3. CSI Driver exposes LINSTOR volumes as standard Kubernetes PersistentVolumes.
Result: any pod or VM that uses a
replicated StorageClass gets synchronous block-level replication across nodes — transparently.🎛 Setting Up Storage
Step 1 — Prepare disks:
# Set up LINSTOR CLI alias
alias linstor='kubectl exec -n cozy-linstor deploy/linstor-controller -- linstor'
# Check what LINSTOR sees
linstor node list
linstor physical-storage list
If disks don't appear, they likely have leftover metadata. Clean them:
# Using talm (installation covered in POST 9)
# WARNING: never wipe the OS install disk (machine.install.disk) — only data disks.
talm -f nodes/node1.yaml wipe disk nvme0n1 nvme1n1
Step 2 — Create storage pools (ZFS):
linstor physical-storage create-device-pool \
zfs node1 \
/dev/nvme0n1 /dev/nvme1n1 \
--pool-name data \
--storage-pool data
Repeat for each node.
Step 3 — Verify:
linstor storage-pool list
You should see a
data pool on each node with available capacity.Step 4 — Use it:
Any application that specifies
storageClass: replicated now gets DRBD-replicated volumes (three replicas by default). PostgreSQL, MongoDB, VM disks — all of them.# In any application config:
values:
storageClass: replicated
size: 50Gi
🛟 What happens when a node fails:
1. DRBD detects the node is gone
2. The volume remains available on the surviving replica node
3. Kubernetes reschedules the pod to a node that has the replica
4. When the failed node comes back, DRBD automatically resyncs
No manual intervention. No restore from backup. No data loss.

New Cozystack Highlights: Persistent Public IPs.
Today IP addresses in Kubernetes are ephemeral. You create a LoadBalancer service, you get an IP, you delete the service, the IP is gone. Recreate it and you get a different one. For anyone running real workloads on public IPs, that churn is a problem, and Cozystack users have been asking to fix it for a while.
The prototype shown at the last community meeting borrows the model everyone already knows from storage: just like a PersistentVolumeClaim binds to a PersistentVolume through a StorageClass, an IPAddressClaim binds to an IPAddress through an IPAddressClass.
What that unlocks:
— Reserve an IP before attaching it to anything, then bind it to a service via annotation
— Delete the service, the IP stays reserved and comes back to the same claim
— Move one reserved IP between services without losing it
— Contention policies: keep an IP alive after its claim is deleted, or release it back to the pool
— A reserved IP can't be stolen by another service
The design is deliberately platform-agnostic. The core controller handles the claim-to-address logic; a separate driver talks to the backend, MetalLB today, but the same pattern fits AWS Elastic IPs or anything else, much like a CSI driver for storage.
Still a prototype, but the direction is set: IP addresses become a first-class, reservable resource in Cozystack.

Blockstor — a new storage control plane for Cozystack, written from scratch in Go.
LINSTOR-compatible: it keeps the LINSTOR CSI driver and Piraeus operator, and uses the Kubernetes API as the single communication plane between controllers and satellite nodes.
Andrei @kvaps walks through the migration tool, the blockstore CLI, synchronous DRBD replicas, RWX via NFS-Ganesha for AI workloads, and block-level live migration for VMs.
Plus the roadmap: BYOK encryption and a QEMU/QCOW2 backend.
Ends with Q&A: API server crashes, leader election, and running alongside LINSTOR.
