Per operator review (#1899): the hive's own domain should never be
typed by hand. Remove the --domain flag from peer-config and wg init
entirely; both now resolve it from the daemon (HostRequest::HiveDomain).
peer-config errors with a clear hint if the daemon can't answer; wg init
prints the peer block best-effort (skips it, still enables the mesh, if
unresolved). Regenerated docs/tools/hivectl-cli.md.
Per operator review: hivectl shouldn't make the operator retype this
hive's own domain. Add a HostRequest::HiveDomain admin-socket query
(c0re answers from HYPERHIVE_HIVE_DOMAIN, already in its service env) and
a domain field on HostResponse.
hivectl peer-config now resolves the domain as: --domain override (kept
for offline/scripted use), else the daemon query; errors with a clear
hint when neither resolves. wg init resolves it best-effort too, so it
prints the hand-over peer-config block without --domain (skipped, not
failed, when the daemon is unreachable).
Regenerated docs/tools/hivectl-cli.md.
Add `hivectl peer-config --domain <this-hive-domain>`: prints the
`services.hyperhive.swarm.peers."<domain>"` nix block a peer operator
pastes to federate with this hive. Emits `caCert = ./<hive>-ca.pem` plus
a `cp /var/lib/hive-tls/ca.pem ./<hive>-ca.pem` line when this hive
serves a self-signed CA (the cert file exists); omits caCert for
ACME/public-CA hives (trusted by the default bundle). Includes the
WireGuard public key when the mesh key exists, and the
wireguardAddress/Endpoint passed via flags.
`wg init` gains an optional --domain; when set it calls peer-config at
the end, so a fresh mesh setup prints the hand-over block in one command.
Pure output — reads local state (TLS CA cert presence, wg key), never
mutates. Regenerated docs/tools/hivectl-cli.md.
Closes#1897.
New agents get a btrfs subvolume state root automatically when the host
FS is btrfs, but agents that predate that migration are left on plain
dirs and miss the subvolume feature set (snapshots, per-subvol
usage/quota, send/receive migration). Add an opt-in operator verb to
convert an existing plain-dir agent in place.
btrfs cannot promote a directory to a subvolume in place, so the new
privileged op stages a sibling subvolume mirroring the dir (create +
`cp -a --reflink=auto` preserving ownership/permissions/xattrs + match
the root's owner and mode), then atomically renames the original aside
and the subvolume into place, then removes the original. Any failure
before the swap leaves the original untouched; idempotent (no-op if
already a subvolume) and btrfs-gated.
The `hivectl subvol upgrade <agent> --yes` verb composes it client-side
like `restart`: stop the agent so its state bind-mount is released, run
the migration via hive-priv, then restart it — the restart is attempted
regardless of the migration outcome so a failed migration never leaves
the agent down.
- hive-sh4re: UpgradeAgentSubvolume priv request variant.
- hive-priv: the migration handler plus stage/cleanup helpers.
- hive-c0re: priv_client wrapper and the hivectl verb; regen CLI docs.
Follow-up to the btrfs-subvolume migration. Operator-opt-in disk
accounting + quotas on agent state subvolumes via btrfs qgroups:
- three privileged ops (qgroup ops need root): EnsureBtrfsQuota
(btrfs quota enable on the agent-state filesystem — statfs-gated,
idempotent, no-op off btrfs), ReadSubvolumeUsage (btrfs qgroup show
-f --raw for one agent), SetSubvolumeQuota (btrfs qgroup limit, or
clear). Reuses the is_on_btrfs helper from the subvolume work.
- priv_client wrappers, incl parse_qgroup_usage -> (referenced,
exclusive) bytes.
- hivectl 'quota' subcommand: enable / show [agent] / limit <agent>
<size|none>, with a K/M/G/T size parser + human-readable output.
Quota is deliberately NOT auto-enabled: btrfs quota enable triggers a
full rescan that is I/O-heavy on a large filesystem, and the operator
should choose when to pay that. 'quota show' on a plain-dir agent (no
subvolume) reports no qgroup data rather than erroring.
One-time-setup convenience for the inter-hive WireGuard mesh
(services.hyperhive.swarm) so nobody has to remember the wg dance:
- hivectl wg init [--address X] — generate (if absent) the hive's
private key at /etc/wireguard/hive.key (0400, never clobbered),
derive + print the public key, and print the swarm.wireguard nix
snippet to enable the mesh.
- hivectl wg peer <domain> --pubkey --address [--endpoint] — print the
swarm.peers.<domain> nix snippet to add a remote hive.
- hivectl wg status — wrap wg show wg-hive.
Hybrid model per the design: the verb owns the imperative state (the
key file), the operator pastes the printed nix into host config (kept
in git) — nothing mutates declarative config behind their back.
hivectl-only (root host ops, like the gateway htpasswd verbs); no
priv/wire/c0re changes.
flake: wrap hivectl with wireguard-tools on PATH so wg resolves even
before the mesh config (which would otherwise pull it in) exists —
wg init is the first setup step. Add clippy.toml doc-valid-idents for
the WireGuard proper noun. Regenerate hivectl-cli.md.
Add a 'hivectl completions <shell>' subcommand (clap_complete) that
prints a completion script for bash/zsh/fish/elvish/powershell, generated
from hivectl's own clap command tree so it never drifts from the real
verbs/flags. The package build installs the bash/zsh/fish scripts via
installShellFiles, so an operator gets working completion automatically
once hivectl is on their profile with shell completion enabled.
Regenerated docs/tools/hivectl-cli.md for the new verb.
Drop the enumeration of what the flag does not apply to, per operator
review on the sibling graceful-stop change. Regenerate the CLI doc so
the markdown-docs self-diff check stays in sync.
`hivectl restart [scope]` cycles the scoped containers — composes the
existing stop + start daemon ops client-side (reusing the merged Stop/Start
wire ops + global --socket), so no new wire/c0re surface. Same scope model
as stop/start (--agents/--agent/--ci/--forge/--gateway/--matrix), and
--graceful on the stop half. If the stop phase reports a failure the start
phase is skipped so a half-stopped hive isn't blindly started over.
Regenerated docs/tools/hivectl-cli.md.
The host admin socket path was duplicated on every daemon-assisted verb
(agents restart/restart-all, stop, start). Hoist it to a single global arg
on the top-level Cli (`--socket`, default DEFAULT_HOST_SOCKET, accepted
before or after the subcommand) and thread cli.socket through dispatch.
Verbs that don't talk to the daemon ignore it. Pure CLI-ergonomics change;
no wire/behaviour change. Regenerated docs/tools/hivectl-cli.md.
The hivectl-docs flake check regenerates docs/tools/hivectl-cli.md from the
clap command tree and asserts it's committed up to date. Adding the stop/start
verbs changed the CLI, so the doc was stale and the check failed. Regenerate it.
