RUNBOOK — BYO deployment (a host Felhom does NOT own)
0. Prerequisites
- Hub customer created; retrieval passphrase delivered to the box owner over a secure channel (typed at a no-echo prompt — never on the command line).
- Cloudflare tunnel + API tokens on the customer config (the dashboard publishes on their domain).
- (Optional, recommended) Pre-enable offsite on the customer config — the descriptor + one-time password wait harmlessly, and day-0 wires offsite hands-off, answering the customer-egress reachability question in the first report cycles.
- Owner-side facts to collect up front (one command for them:
pvesm status):- storage names for
--acl-storages(which storages may Felhom WRITE: minimum the archive storage —local— and the guest-restore storage); - is there an LVM-thin (
local-lvm)? The guest restore target defaults tolocal-lvmand there is currently NO flag to change it — a ZFS-only box needs the--restore-storageinstaller follow-up first (open item); - cluster? → node name (the installer REFUSES multi-node without an explicit
--node— the wrong-node footgun guard, verified live); - agreed guest slice (cores/MiB — REQUIRED in byo mode) and vmid (default 9201; check
pct list+qm listfor collisions — the owner may have 100+ guests).
- storage names for
1. The trust conversation (what the owner will ask — verified answers)
- "Nothing changes on my system?" Additive-only, and provable: (a)
--dry-runprints every mutating command with zero execution; (b) the real install prints the full host-mutation list and requires typed consent; (c) write containment:Datastore.Allocate/AllocateSpaceONLY on the storages they name (verifiable:pveum user permissions felhom-agent@pve --path /storage/<any>), read-only Audit elsewhere (the monitor needs to SEE all storages — by design); (d) VM privileges exist only at/pool/felhom— their existing guests are permission-unreachable; (e) no network/bridge/sysctl/HA/ storage.cfg changes; (f)--uninstallreverts fully. - Root password: the installer ROTATES root@pam to a generated recovery credential vaulted to the hub — tell the owner BEFORE the install, not after they're locked out of the PVE UI.
- The agent runs non-root behind a fixed-argument sudoers allowlist; disk formatting exists only for drives the owner explicitly enrolls (type-to-confirm; data-bearing devices refused without an operator signature).
2. Preflight (read-only — installs nothing, not even the agent)
curl -fsSL https://felhom.eu/scripts/felhom-host-install.sh -o felhom-host-install.sh \
&& sudo bash felhom-host-install.sh --customer-id <ID> --mode byo \
--cores <N> --memory <MiB> --node <node> --acl-storages "local <restore-storage> [...]" --preflight-only
Reads PVE version, storages, RAM, guest count; DIES with the exact remedy on findings (missing ACL storage names, foreign DNS resolver on :53 — refuse-over-mutate). Multi-storage syntax: ONE quoted, space-separated argument.
3. Install
Same command minus --preflight-only; passphrase at the prompt; typed consent after the mutation list.
If it fails mid-way: fix the finding and re-run with --resume (idempotent; keep the full corrected
argument list, e.g. the widened --acl-storages). Permission 403s at the restore step = the ACL list is
missing the storage named in the error → --rescope-acl --acl-storages "<corrected list>", then --resume
(live-verified recovery path).
4. Cluster rules (verified live — hand these to the owner in writing)
- The Felhom guest is node-local by design: agent, guest hook (agent-installed under the node's
local:snippets), and physical/NAS drive binds all live on the install node. - Never add the guest to HA resources; never migrate it. Four node-locality layers break on a foreign node: binds (empty), agent (unreachable → controller shows the WRONG node's storage data), guest hook (missing → the guest fail-closed refuses to start — a feature), and the controller's fixed agent-endpoint. Everything self-heals on migrating back.
- The cluster itself is untouched: pveum entries replicate via pmxcfs (inert), corosync/HA/quorum are never modified.
5. Verify (remote, hub-side — no SSH exists to a BYO box, by design)
Host + guest appear on the hub within a cycle; controller at the floor version (updates are floor-driven
and, since v0.112.0, credential-free — the Git Sync fields are ONLY for private catalogs); tunnel
Healthy; dashboard live on the customer domain. If offsite was pre-enabled: report shows
offsite: pending — proof the bridge consumed the one-time password and installed its key from the
CUSTOMER's egress. Then → RUNBOOK-escrow-ceremony (note the K prerequisite there: a BYO box without the
PBS tier needs agent ≥ v0.80.0 identity-only mode).
6. Data storage for apps (BYO owners rarely hand over disks)
Preferred: NAS share (Hálózati tárhely) — NFS or SMB, mounted host-side under /mnt/felhom-drives/,
role-gated bulk-userdata, automount. NFS recipe (live-verified): a DEDICATED export (never reuse their
backup share — all_squash would break its other clients), options
rw,no_subtree_check,insecure,all_squash,anonuid=101000,anongid=101000, directory owned 101000:101000
(container uid 1000 + the unprivileged-LXC +100000 offset — the agent source documents this as the
export's job). NFSv4 path = pseudo-root-relative (/export/foo on the server → enter /foo).
UI uid field: the app's container uid (1000). Physical drive enrollment stays available if they dedicate
an empty disk.
7. Rollback
--uninstall (guest destroyed, agent + config + .bak purged, optional --remove-golden) — the promise
from Step 1, kept.
