Abstracts:
### Piotr Zaniewski - Kubernetes Without the Kubernetes: Local Dev with vind
What if you could run a complete, production-compatible Kubernetes cluster without any Kubernetes? https://github.com/loft-sh/vcluster (vCluster in Docker) creates fully functional Kubernetes environments using only Docker containers—no host cluster, no kind, no minikube.
This talk explores how vind reimagines local Kubernetes development:
The Problem
Tools like https://kind.sigs.k8s.io/ and https://minikube.sigs.k8s.io/ require complex image loading workflows (kind load docker-image), lack working LoadBalancer services, and struggle with multi-cluster scenarios. Developers waste hours fighting tooling instead of building.
The Solution
vind runs the Kubernetes control plane and simulated worker nodes as Docker containers, sharing your host's Docker daemon. This enables:
- Zero image management - Pull-through registry proxy uses your local Docker cache
- Working LoadBalancers - Services of type LoadBalancer just work, reachable from localhost
- Multi-node simulation - Configure multiple worker containers with individual settings
- External node joining - Connect real machines via https://www.vcluster.com/docs/configure/vcluster-yaml/private-nodes/vpn for hybrid testing
### Dr. Stefan Schimanski - Tracing Causality Through Controllers:
Protecting Your Infrastructure
Kubernetes controllers automate rollout and lifecycle. But as humans step further out of the loop, the risks grow substantial.
This talk recounts an incident where hundreds of expensive GPU nodes were lost—left idling, burning thousands of dollars per hour. The root cause? The controller pattern we all rely on.
After a decade of this pattern, we still lack a fundamental concept: causality. Why does something happen? Is it user intent—or an accident along the way?
Every layer applies desired state blindly, potentially wiping out critical infrastructure. One update can brick an entire fleet. Automated. Fast. Disastrous.
This talk introduces Kausality, a project designed to fill that gap.
