The gateway's nginx + dnsmasq no longer run in their own nspawn container.
`nix/host-modules/hive-gateway/default.nix` loses the
`containers.hive-gateway` wrapper and everything that existed only to punch
holes in it: `privateNetwork = false`, `CAP_NET_ADMIN`, five bind mounts,
its own `stateVersion`, `networking.firewall.enable = false`,
`networking.resolvconf.enable = false`, and the `hive-gateway-resolv`
path+service pair. 465 -> 303 lines.
The container never bought isolation here. It shared the host netns by
necessity — nginx binds the host's :80/:443, dnsmasq answers on the bridge —
so each of those settings was undoing a boundary the gateway could not
afford in the first place.
Four things made it more than a deletion, none of them visible in the nix
diff:
- The self-signed cert service also imports the hive CA leaf, so removing it
with the container would have left nginx naming a missing cert file, which
it refuses to load at all.
- The nginx reload is a hive-priv verb. It still needs root, but no longer
for the reason its doc gave, and `--machine=` was both transport and
scope — so the unit name is now hard-coded in the helper as the
containment.
- The lifecycle verb named a container that stops existing.
- `journalctl -M hive-gateway` had no machine to enter.
Per the operator's ruling, the operator verb keeps working and agents lose
it. `InfraContainer` answered three questions that used to share an answer;
it now splits into `name()` (identity), `target()` (Container vs HostUnit),
`service_unit()` (the systemd unit), and `agent_restartable()`, which the
MCP restart path checks before the capability so the refusal cannot read as
"ask for infra_admin". `SIBLING_CONTAINERS` drops the gateway — it gates the
requests that name a container as a string — while `FromStr` still accepts
it, because that answers what a name is, not who may act on it. The
dashboard's gateway journal reads host journald filtered to `nginx.service`.
Prose was corrected where it only named a location, and re-argued where the
container was doing security work: a `0666` per-agent socket was safe
because only the gateway container had the directory bind-mounted. There is
no mount now, so the directory permissions are the whole of the access
control — the constraint holds, its mechanism doesn't.
Gate: nix fmt / clippy --all-targets -D warnings / cargo test all clean (710
tests); hivectl-cli.md regenerated from the clap tree. The nix eval was run
in both TLS shapes at this commit: every delta in the rendered
virtualHosts is one of the three intended path moves, dnsmasq settings are
byte-identical, and the absence probe flips true -> false with bindMounts
emptied.
One attrset describing every hive in the swarm including this one,
identical on every host, with hiveName selecting which entry is us.
"My peers" is derived (swarm.peerHives) rather than declared.
Every field in the old per-host peer list was intrinsic to the hive it
described, never to the pair -- so the list was a directory each host
kept its own copy of. Beyond the deduplication it removes a bug class:
two hosts could hold different endpoints for the same third hive with
nothing to detect the disagreement.
Drops the per-hive caCert. Trust inside a swarm derives from the swarm
root, which every hive chains to. What that genuinely removes is
trusting a hive whose root this swarm does not own -- a cross-swarm
problem that wants a mechanism of its own, not a field that happened to
work.
The matrix container's certificateFiles block goes with it and could
NOT be migrated: that list is read at build time and the swarm root is
a runtime file (its key must never enter the store), so there is no
build-time name to put there. caCert being a nix path was precisely
what made it the build-time distribution channel. Agents are unaffected
-- hive-tls folds the root into the hive trust bundle and the meta
renderer embeds that one file. Tracked separately.
Migration is an assertion plus warnings, not a rename: hives is peers
union {self}, and the set gains a member no existing config has written
down. A rename migrates a name and a default can re-root a meaning;
neither can conjure a new member. The warning explains, the self-entry
assertion stops the build.
services.hyperhive.c0re.swaggerUiTheme -> services.hyperhive.gateway.swaggerUiTheme.
hive-c0re has no relationship to this option (it's consumed entirely
by the gateway's nginx config) since the previous two commits moved
the theme files out of hive-c0re/ and gateway to hosting the whole
dist itself — the option shouldn't live in c0re's namespace either.
Pure option move: default wiring in flake.nix now sets
services.hyperhive.gateway.swaggerUiTheme instead of the c0re one;
hive-gateway/default.nix reads it via the module's own already-bound
cfg (services.hyperhive.gateway) instead of reaching into c0re's.
Verified: nix build .#swagger-ui-theme unaffected (same store path,
pure option-plumbing change, no content change); a full nixosSystem
eval of nixosModules.default resolves the option at its new path and
confirms the gateway's /api/docs/ location still aliases the correct
store path.
