Prod inventory scaffolding for the three bare-metal nodes, and the become posture the
operator ruled for production.
BECOME: prod does NOT get dev's NOPASSWD sudo. Prod keeps a real sudo boundary and
supplies the password to Ansible as an ansible-vault-encrypted `ansible_become_password`
in inventory/group_vars/k3s_prod/vault.yml, mirroring the existing hypervisor and
proxmox_hosts groups. The decrypting passphrase stays outside the repo
(~/.config/home-k3s/ansible-vault-pass), so plays still run unattended with no plaintext
secret in git. Committed here: README.md + vault.yml.example only — the operator creates
the encrypted vault (`ansible-vault create`), as with every other vaulted group.
PACKAGES BELONG IN THE ROLE (operator ruling): smartmontools is now declared in
node_baseline_packages, not hand-installed on a node. Drive health tooling is a
permanent part of a bare-metal node's baseline — dev nodes are VMs and never needed it.
Same click-ops-never principle as the rest of the repo.
ADDRESSING: nodes .10/.11/.12, reached DIRECTLY on the LAN (no pfSense NAT hop, unlike
dev's 192.168.2.102:225x mapping), so ansible_host is the real node IP. kube-vip
control-plane VIP is 192.168.2.9 — deliberately BELOW the nodes and OUTSIDE the Cilium
LB pool (.20-.30) so kube-vip and LB-IPAM can never contend for an address. The ingress
Gateway VIP (.20) and the LB pool are Flux/cluster-vars concerns and deliberately do
not appear in Ansible.
BLOCKED-BY-DESIGN: node_baseline_longhorn_device / node_baseline_etcd_device are present
but set to an obviously invalid /dev/BLOCKED-... path pending the operator's disk-layout
decision (node 1 is a single SATA SSD; the role's /dev/vdb,/dev/vdc defaults are virtio
names that do not exist on bare metal). Leaving them unset would silently fall back to
those equally-nonexistent defaults — a confusing failure that looks like a wiring bug.
This fails just as hard and says exactly why.
KNOWN FOLLOW-UP: roles/k3s_server and every node-host playbook hardcode the literal
group names k3s_primary/k3s_secondary/k3s_servers, so the k3s_prod_* groups are not
selected by them as-is. Harmless now (nothing can accidentally run against prod) but the
"same roles, unchanged" reuse R-ENV-02 promises needs the target group parameterized
before §6 of PROD-PROVISIONING.md can execute. Documented in hosts.ini and both READMEs.
Serves: R-ENV-01, R-ENV-03, R-SEC-01. Task: T-7.1. Gate: MERGE GATE: PASS.
