OS Images

Hetzner Cloud OS images available for cluster nodes, and why the default is Debian 13.

Hetzner Cloud offers the following Debian/Ubuntu images:

ImageNameRecommendation
debian-13Debian 13 TrixieRecommended for K8s
debian-12Debian 12 BookwormStable, well-proven
ubuntu-24.04Ubuntu 24.04 LTSGood for K8s
ubuntu-22.04Ubuntu 22.04 LTSWell-proven

Why Debian 13?

  • Stability: long support cycles
  • Compatibility: the pkgs.k8s.io apt repository used for kubeadm, kubelet, and kubectl ships Debian packages
  • Small footprint: leaner than Ubuntu, but not as small as Alpine
  • No glibc/musl issues: unlike Alpine, no compatibility problems

Hetzner Cloud doesn’t provide dedicated “slim” or “minimal” variants. The standard images are fairly compact already.
