infra/devcontainer/kubeconfig.sh was never staged into the delivery-A commit, so the branch built on main carried main's single-cluster tooling and `--context k3s-prod` failed with 'context does not exist' mid-incident. Not Flux-reconciled, so it never affected the cluster — but it breaks prod diagnosis from a checkout of this branch, which is when you need it most. Carries the concurrency fix: the merged kubeconfig holds both contexts and NO current-context, with each invocation getting a per-invocation selector file prepended to KUBECONFIG. Two concurrent dev.sh runs with different CLUSTER values previously overwrote each other's current-context mid-command — reproduced live, a CLUSTER=dev reader returned k3s-prod nodes on 3 of 7 iterations.

infra/ — node provisioning and the toolchain
OpenTofu (Proxmox VE) + cloud-init + Ansible bring up the 3-node k3s/Cilium dev cluster.
Spec: ../home-network-k3s/docs/02-environments-and-provisioning.md.
| Path | What |
|---|---|
tofu/ |
The "Create" stage: 3 cloud-init'd VMs on the Proxmox box (bpg/proxmox provider) |
cloud-init/ |
First-boot baseline shipped as a Proxmox user-data snippet |
ansible/ |
The "Baseline"/"Configure" stages: k3s HA, Cilium, kube-vip, the VPN egress gateway |
devcontainer/ |
The pinned toolchain (tofu, ansible, sops, age, flux, kubectl, helm and the whole CI gate toolchain) |
cluster.sh |
RETIRED — drove the old libvirt VMs; does not work against Proxmox |
PHASE1-STATUS.md |
Current state of the cluster and how to reconnect to it |
PHASE1-SCOPE.md |
Historical Phase-1 scoping doc (libvirt era — superseded) |
Where the cluster actually lives
The dev cluster is not on this workstation. It runs on a Proxmox VE host; the nodes sit on the Proxmox LAN and are reached across a pfSense NAT:
| Nodes | k3s-dev-1/2/3 at 192.168.1.50/.51/.52 — 6 vCPU, 24 GiB, Debian 13, k3s v1.36.4 |
| kube-API | kube-vip VIP 192.168.1.49:6443, reached from the workstation via NAT 192.168.2.50:6443 |
| Node SSH | pfSense NAT 192.168.2.102:2250/2251/2252 → node :22 (Ansible only) |
| Ingress VIP | 192.168.1.53 (Cilium L2, shared Gateway); .53–.60 reserved for LB VIPs |
The earlier libvirt/KVM cluster on 10.73.0.0/24 is retired. Any doc or command referencing
virsh, qemu:///system, or 10.73.0.x for the cluster is historical.
