Kuberik: Safe, Hands-Off Deployments for Kubernetes (Luka Rumora)

Most teams deploying to Kubernetes end up in one of two places: either GitOps that stops at applying manifests, or brittle CI pipelines full of bash and glue. Both fall short of true end-to-end delivery.
The ideal is well known—canaries, health checks, smoke tests, promotions, rollback—but Kubernetes lacks a native, reusable way to compose these without reinventing everything.
Existing tools solve pieces (Argo Rollouts, Flagger, Kargo), but not the whole pipeline.
Kuberik fills that gap: it orchestrates the full journey from release to production—detecting, gating, rolling out, verifying, and promoting—using opinionated, pluggable Kubernetes resources that integrate with existing GitOps setups.

Luka is a Lead SRE with 10 years of experience building platform infrastructure and internal developer tooling, always with the same focus: systems that are robust, easy to maintain, and a pleasure to use. Over the years, he has watched the delivery tooling landscape change, from Jenkins to GitLab CI to Drone to GitHub Actions, yet the fundamental approach to CD has stayed the same: step-based pipelines with the same challenges they had a decade ago. He built Kuberik because he believes we can do better.

Kubernetes Without the Operator: A Minecraft Panel with Rust and kube-rs (Hadi Cherkaoui, CM Informatik AG)

Anvil is a Kubernetes-native Minecraft server panel written in
Rust. It creates one StatefulSet, PVC, and Service per server
through direct kube-rs calls, with no CRD and no controller. The
Kubernetes API itself is the runtime state store; every user
action is a direct API call.

This 20-minute talk argues that the operator pattern is sometimes the
wrong tool. Controllers earn their complexity when there's
autonomous state to reconcile. They become a ceremony when there
isn't. Anvil is a worked example of the imperative alternative,
running on a home lab k0s cluster.

Hadi Cherkaoui is a 17-year-old EFZ Plattformentwickler apprentice
at CM Informatik AG in Schwerzenbach, ZH. He works daily with k0s
and FluxCD, and is interested in Kubernetes, Rust, infrastructure
automation, and homelab projects.

Vibe Code Survival Guide for Open-Source (Vadim Bauer, Container-Registry.ch)

Vibe code is flooding open-source projects with an ever-growing volume of pull requests and ideas.
Banning AI contributions isn't the answer, yet it is difficult to resist.
How can open source projects survive and keep progressing despite the pressure?
This talk covers the project playbook we're building in CNCF Harbor and Harbor Satellite: defining a clear project direction so contributors, human or AI-assisted, know what's in scope before they contribute. Setting explicit acceptance criteria and guardrails. Using AI on the maintainer side to triage, review, and filter the growing volume of contributions. Deciding as a project where your boundaries are, what's core, what's an extension, and what's out of scope, so you stop drowning in well-intentioned feature PRs that slowly erode coherence.
We share what works, what fails, and how we are rethinking open-source, contributions, community, and project

Vadim Bauer is a Container Silverback with over a decade of experience in running containers in production. As a maintainer of the CNCF project Harbor, he focuses on extending the boundaries of OCI artifact management, adoption, and developer experience. At 8gears, Vadim helps cloud providers, ISVs, and enterprises adopt Harbor and use OCI capabilities.

Writing a Kubernetes Cluster Autoscaler Provider with externalgrpc (Marco De Luca, VSHN)

The Kubernetes Cluster Autoscaler decides when to scale, but it doesn't know how to create a VM. That's the cloud provider's job, and the upstream tree covers mostly big clouds. With externalgrpc, you can plug virtually any cloud into the autoscaler over gRPC.
This talk first looks at how the Cluster Autoscaler works under the hood and where the cloud provider fits in. Then we walk through implementing one for a Swiss IaaS provider as an out-of-tree gRPC service: the design choices, the parts of the contract that matter, and the gotchas you only find by reading the autoscaler source. By the end, you'll know how to attach autoscaling to a cloud that isn't on the upstream list.

Marco De Luca is a software/infrastructure engineer at VSHN AG. He spends most of his time on Kubernetes platforms, developer tooling, and making sure things don't break at 3 AM. At mdnix.io, he writes about infrastructure, Linux, Kubernetes, and the things he builds along the way. When he's not behind a terminal, he's somewhere in the Alps with his camera or having a private jam session with his guitar.
