Raw Blame History

Role: k3s

Installs a single-node K3s cluster on Debian bookworm. Used as the runtime for the ess-pro role.

Design choices

  • Traefik disabled inside K3s because the project's DMZ Traefik already fronts the cluster. Routing happens via NodePort/ClusterIP through the external Traefik. If you want K3s' bundled Traefik as the ingress controller, remove traefik from k3s_disable_components and adjust the upstream Traefik to route by host headers only.
  • servicelb (Klipper) disabled for the same reason — no LoadBalancer services needed in the PoC.

Variables

See defaults/main.yml. Override k3s_version to pin a specific K3s release. The cluster/service CIDRs default to K3s' standard ranges; only change if they clash with your libvirt networks.

Usage

- hosts: vdmzess01
  roles:
    - role: k3s
    - role: ess-pro
