Mind the Flannel MTU on Hetzner private networks, separate stateless and stateful workloads at the storage layer, keep observability minimal but real, and treat backups as a tested practice rather than a config setting.</p> <p>A managed Kubernetes service is the right answer for most teams. When it is not the right answer (cost, control, locality of data), self-hosted k3s on a low-cost provider like Hetzner is one of the better options. We have run several clusters of this shape in production for over a year. This post is the set of decisions that have held up.</p>
