Bootstrap a regular (non-ITAR) k3s cluster on cnode1/2/3 with embedded
etcd. All cluster communication — node registration, API server, etcd
peering, flannel VXLAN — runs exclusively over Tailscale IPs. Zero LAN
addresses appear in node status or TLS certificates.
Scripts (k8s/):
- env.sh: shared config (Tailscale IPs, SSH opts, k3s version)
- wipe.sh: remove existing k3s from all cnodes
- install-cp.sh: full bootstrap (cnode1 --cluster-init, then cnode2/3 join)
- join-servers.sh: re-join cnode2/3 only (fixes broken join state)
- post-setup.sh: apply NoSchedule taints, fetch kubeconfig, verify
- verify.sh: 13-point health check (nodes, Tailscale IPs, taints, etcd,
CoreDNS, API server, workload isolation)
- probe-nodes.sh: SSH + Tailscale reachability check
All 3 cnodes are tainted control-plane:NoSchedule so no user workloads
can schedule on the control plane. 13/13 health checks pass.
Docs updated: k8s README TL;DR reflects k3s (not Talos) as the deployed
choice, with Talos preserved for the future ITAR cluster.

## Current State: STABLE
|
|
|
|
The merged PFVCluster repo is fully operational across provisioning, DNS
|
|
infrastructure, Proxmox cluster ops, and k8s control plane.
|
|
|
|
## Completed Work
|
|
|
|
### Server Provisioning (validated on sectestbed-sandbox)
|
|
- [x] SetupNewSystem.sh deploys end-to-end to rc=0 (Debian 13 trixie)
|
|
- [x] Security hardening: SSH, SCAP-STIG, Wazuh, 2FA (SSH+Cockpit+Webmin)
|
|
- [x] NTP: redundant pfv-netinfra-01/02 (192.168.3.252/253), synced stratum 3
|
|
- [x] DNS resolv.conf: managed static file pointing at netinfra pair
|
|
- [x] Test suite: 5 tests (framework, safe-download, 2fa, https, system-req)
|
|
- [x] VM validation harness: git-based deploy + auto-rollback + guest-agent access
|
|
|
|
### DNS Cluster (pfv-netinfra-01/02)
|
|
- [x] Production Technitium config replicated from tailscale-router (read-only)
|
|
- [x] 124 zones on both nodes (knel.net + reverse DNS)
|
|
- [x] pfv-netinfra-01 = PRIMARY, pfv-netinfra-02 = SECONDARY
|
|
- [x] Zone replication via rsync systemd timer (every 60s)
|
|
- [x] Credentials + 2FA replicated identically to production
|
|
- [x] Both LAN IPs resolve knel.net device names + recurse externally
|
|
|
|
### Proxmox Cluster Ops
|
|
- [x] 5 of 7 hosts fully performance-tuned (tsys1/3/6/7/9)
|
|
- [x] Fleet audit complete (PROJECT.md has ground truth)
|
|
- [ ] tsys4: blocked on PCIe NIC + RAM install
|
|
- [ ] tsys5: blocked on 2nd ethernet cable + NVMe install
|
|
- [ ] tsys2: pending rebuild from Win10 to Proxmox
|
|
|
|
### Kubernetes Control Plane (k3s HA — LIVE)
|
|
- [x] 3-node k3s HA control plane deployed: cnode1/2/3 (v1.36.2+k3s1, embedded etcd)
|
|
- [x] **All traffic over Tailscale IPs** — no LAN IPs in node status or certs
|
|
- [x] All 3 cnodes tainted `control-plane:NoSchedule` (zero user workloads)
|
|
- [x] 13/13 health checks pass (verify.sh): nodes Ready, etcd quorum,
|
|
Tailscale IPs, CoreDNS, API server, workload isolation
|
|
- [x] Scripts in `k8s/`: wipe, install-cp, join-servers, post-setup, verify
|
|
- [x] Kubeconfig saved to `~/.kube/config.pfv-k8s` (gitignored, embedded certs)
|
|
- [ ] Workers (wnodes) not yet joined to this cluster
|
|
- [ ] Distro decision: **k3s chosen for regular R&D cluster**. Talos docs
|
|
preserved in `docs/k8s/` for future ITAR/classified cluster.
|
|
|
|
### Repo Merge
|
|
- [x] KNELServerBuild merged into PFVCluster (history preserved)
|
|
- [x] Directory structure reorganized (provisioning/, tests/, perf/, docs/)
|
|
- [x] All docs gardened: links fixed, stale refs removed, tailscale.md updated
|
|

## Known Issues
|
|
|
|
| Issue | Impact | Status |
|
|
|-------|--------|--------|
|
|
| Technitium AXFR uses port 53 (occupied by Pi-hole) | Zone transfer via rsync instead of native AXFR | Workaround in place |
|
|
| `download.proxmox.com` unreachable from sandbox VM | 2 validation tests warn (environmental) | Not a code issue |
|
|
| tsys4/5 hardware pending | Perf tuning incomplete on 2 hosts | Waiting on physical install |
|
|
|
|
## Pending (next session priorities)
|
|
|
|
1. **k8s workers:** Join wnodes to the k3s cluster (agents, not servers)
|
|
2. **k8s: confirm 3 decisions** for future Talos/ITAR cluster:
|
|
- Cnode count: 3 (recommended) vs 5
|
|
- Cnode host spread: tsys9 + tsys1 + tsys3 (recommended, 3-host, local-lvm)
|
|
- Tailscale pattern: subnet router on `tailscale-router` (recommended)
|
|
3. Provisioning: add `tailscale up --accept-dns=false` after resolv.conf deploy
|
|
4. DNS: verify Pi-hole forwards knel.net to local Technitium on both nodes
|
|
5. Perf: complete tsys4/5 tuning after hardware install (Friday)
|
|
6. tsys2: rebuild from Win10 to Proxmox (k8s-dedicated host)
|
|
7. **k8s deferred topics** (tracked for future sessions): ETL tooling
|
|
(GDAL/PostGIS/xarray/Dask → RWX vs RWO), HPC scheduler (Argo/Volcano),
|
|
per-tenant vcluster policy templates, solar-aware scale-out
|
|
|
