Replace Hetzner infrastructure and cloud-provider assumptions with Proxmox
VM clones, kube-vip API HA, and NFS-backed storage. Update bootstrap,
Flux addons, CI workflows, and docs to target the new private Proxmox
baseline while preserving the existing Tailscale, Doppler, Flux, Rancher,
and B2 backup flows.
Update the baseline to treat Rancher backup and restore validation as part
of the accepted platform state, and capture the successful live drill run
performed on 2026-04-18.
Add a post-deploy smoke test that validates Tailscale DNS, proxy readiness,
reachability, and service responses for Rancher, Grafana, and Prometheus.
Move the operator to the stable Helm repo/version and align the baseline docs
with the current HA private-only architecture.
Major changes:
- Terraform: Scale to 3 control planes (cx23) + 3 workers (cx33)
- Terraform: Add Hetzner Load Balancer (lb11) for Kubernetes API
- Terraform: Add kube_api_lb_ip output
- Ansible: Add community.network collection to requirements
- Ansible: Update inventory to include LB endpoint
- Ansible: Configure secondary CPs and workers to join via LB
- Ansible: Add k3s_join_endpoint variable for HA joins
- Workflow: Add imports for cp-2, cp-3, and worker-3
- Docs: Update STABLE_BASELINE.md with HA topology and phase gates
Topology:
- 3 control planes (cx23 - 2 vCPU, 8GB RAM each)
- 3 workers (cx33 - 4 vCPU, 16GB RAM each)
- 1 Load Balancer (lb11) routing to all 3 control planes on port 6443
- Workers and secondary CPs join via LB endpoint for HA
Cost impact: +~€26/month (2 extra CPs + 1 extra worker + LB)
Document the successful completion of Hetzner CCM and CSI integration:
- CCM deployed via Ansible before workers join (fixes uninitialized taint)
- CSI provides hcloud-volumes StorageClass for persistent storage
- Two consecutive rebuilds passed all phase gates
- PVC provisioning tested and working
Platform now has full cloud provider integration with persistent volumes.
