The mint creates each client's secret in the swarm secret store and writes only the digest to disk. It mints only when the store answers and holds none. A new unit moves the plaintext files an earlier release left into the store and removes each once the store holds the same value. The bridge reads its secret from the store into /run before each start. The secret publisher unit and its path unit are gone.
The swarm-nats container now runs its own otel collector, which reads the
container's journal and pushes it to the swarm collector at
https://<swarm.otel.domain>/swarm-nats, authenticated as the queue's
existing OIDC client (swarm.nats.clientId). Records carry
service.name=nats and no hive label.
The collector lives in a reusable container module,
nix/container-modules/swarm-journal-forwarder.nix, which follows
swarm-bao's forwarder: a journald receiver over /var/log/journal with
merge and a file_storage cursor, an otlphttp exporter with an
oauth2client authenticator that requests its own client id as audience,
self-metrics on a loopback telemetry port, and the client secret handed
in through LoadCredential. Unlike swarm-bao, the secret is fetched inside
the container by swarm-journal-forwarder-oidc.service, under the
container's own store identity (the swarm-nats-auth leaf, which already
holds a read grant on secret/swarm/services/swarm-nats/oidc/client).
The fetch retries until the store answers, and the collector restarts
until the file exists. A 10-minute timer re-reads the secret and restarts
the collector when it changed.
The swarm collector's authenticated producer route was hard-wired to
swarm-bao. It is now rendered from swarm.otel.serviceProducers
(internal), one receiver, oidc authenticator, gateway location and
pipeline entry per service: swarm-bao (port 4391, unchanged names) and
swarm-nats (port 4392). The reserved-fragment and port-collision
assertions cover every entry.
The queue's OIDC client registration gains its own id as audience and
RS256-signed access tokens, which the receiver verifies offline.
swarm-nats drops --link-journal=host, so its journal stays in the guest
where the forwarder reads it, as swarm-bao did in 44009dc51. The new
swarm.nats.otel.telemetryPort (8891) keeps the forwarder off the
collectors' 8888-8890 in the shared host netns, with an assertion.
module-eval-nats-authelia gains four cases: the container's forwarder
and fetch unit on the store host and on a queue-only host, the
responder role's read grant, the swarm collector's swarm-nats receiver
on a host without the queue, and the client registration.
Part of #4499
Part of #5342
The three client registrations move into glue-{controller,nats,matrix}-oidc-client.nix,
gated only on deploy.authelia.enable and reading their ids from swarm.* options,
so the host running authelia registers every one of them whichever host runs
the service. The matrix callback is a new read-only swarm.matrix.sso.redirectUri,
read by both the homeserver's config and its client entry.
swarm-secret-publish now also publishes the queue's and the homeserver's minted
secrets to swarm/services/<id>/oidc/client. The queue host reads its responder's
secret there with swarm-bao-nats-auth-oidc under the responder's own leaf
(swarm-nats-auth role gains that one read path), and the homeserver's host with
swarm-bao-matrix-oidc under matrix-ctl's leaf (swarm-matrix-ctl role gains its
one read path). The host-file copies are gone: swarm-nats-auth-secrets now
delivers only the callout seeds and the store identity, and
hive-matrix-oidc-secret is removed. A fetch unit whose leaf is unset still
renders and fails naming the option pair.
Closes#4943
