Deferred until the collector had a logs pipeline writing to it: a store
nothing writes to starts, answers queries and returns nothing, so the first
person to look concludes there were no logs rather than that nothing was
collecting them.
Drops swarm.otel.url (a loopback default an operator had to override on a
split host) in favor of swarm.otel.domain -- the same
gateway.localNames + nginx-vhost-through-the-gateway shape every other
swarm service (authelia, grafana, victoriametrics, ui) already uses. The
hive tier's exporter now reaches it as https://<domain> unconditionally,
resolved locally by dnsmasq on a co-located host and over the real network
otherwise, instead of a config knob nobody sets until they hit the silent
drop.
Costs CA trust on the hive tier: otel.nix wires
lib/hive-ca-trust.nix's trustBundle with hostUnit = true on the
opentelemetry-collector host unit, the same flag #3441/#3442 added for
swarm-controller and hive-c0re.
mara, #3125 comment 58363: "go c".
All four sibling swarm containers import swarm-container-resolver.nix;
this one did not. It matters more here than most: otel.endpoint is an
operator-configured external hostname, and reaching it is the entire
reason this container holds a credential.
Also aligns two details with those siblings - the enable default is
asserted from swarm-required-services.nix with the metrics pair it
feeds, so that file remains the one place a service host is declared,
and machine is readOnly since its description already calls it a fact
rather than a knob.
Review feedback: the metrics pair had nothing writing into it, and it sat
outside the switch that turns on every other swarm-wide service.
The collector now exports to VictoriaMetrics as well as upstream — a
fan-out, not a choice: a local store is for looking at this swarm, an
upstream is for whoever aggregates across swarms.
That makes a local store a complete destination on its own, so
`otel.endpoint` is no longer required when it runs here; a hive with
neither is still refused. The assertion only ever relaxes, so every
config that evaluated before still does.
`enableRequiredServices` now derives both halves, alongside matrix,
authelia and nats. They derive together because a store with no UI is
unreadable and a UI with no store is empty.
enableRequiredServices asserts the services that exist once per swarm and
are optional -- its own description says so -- and the queue meets that
rule. It was left out because this file predates the swarm-nats container
by nine days and was never revisited, not because anyone decided against
it.
The all-local mode already derives nats.autoGenerateCallout, so it was
minting the queue's callout nkeys and never starting the queue. With this
the mode's loopback derivation for the controller points at something
that is actually running.
mara: enableAllLocalDefaults is more of a deployment mode via settings
set, less a default setting.
That reframing is the change. A mode asserts values; an option declares
what it is when nobody asks. Written as default = <flag>, every service
option had to name a switch it has no relationship to, and the answer to
what does all-local turn on was spread across five files.
Two modules now hold the two tiers - local-defaults.nix for the mode and
what it asserts directly, swarm-required-services.nix for the
services-live-here switch and the per-service enables under it. Each
service module keeps its own declaration and loses only the line about
when a deployment wants it.
mkDefault is the right precedence rather than a compromise: it beats an
option default and yields to any explicit definition, so the mode fills
in for an operator who has not spoken and never argues with one who has.
Evaluated config is unchanged in both directions.
