read_with_startup_retry retries the first read of a client secret through a store that is restarting. Nothing in swarm-queue-client calls it; its only callers are the four binaries that read the secret (swarm-builder, swarm-claude-login, swarm-controller, swarm-review-classifier), and they already depend on swarm-secret-client. It sits beside stored_secret, which moved there in #5538. swarm-queue-client drops its backon dependency and the tokio test-util dev-dependency that only these tests used.
The module is a rename (97% similar); everything else in the diff follows
from the move:
- stored_secret.rs: private `chain()` helper, the 8-line copy of the queue
crate's `chain` the module called as `crate::chain`; the queue crate's
public `chain` stays.
- stored_secret.rs: `Duration::from_mins(5)` in `MAX_REREAD_DELAY` is
unchanged moved code, not a new use.
- swarm-secret-client Cargo.toml: gains futures-util, tokio and tracing as
dependencies and tokio `test-util` plus tracing-subscriber as dev
dependencies; the module and its tests use them.
- swarm-queue-client Cargo.toml: drops futures-util and the tracing-subscriber
dev dependency, which only the moved module used; its tokio dev comment is
reworded to the tests that remain.
- Cargo.lock: the same dependency moves, nothing else.
- swarm-queue-client lib.rs: imports `swarm_secret_client::stored_secret`,
and its tests use a small local `Store` in place of the moved module's
test-only `Fake`, which is no longer reachable.
- callers (hive-c0re, swarm-builder, swarm-ci-metrics, swarm-claude-login,
swarm-controller, swarm-nats-auth, swarm-review-classifier): import path
only; no re-export is left behind.
swarm-secret-publish and its path unit now run inside authelia's container,
beside the mint, and read each client secret at the path authelia writes it.
The host unit and host path unit, which read the secrets through the
container's root on the host, are gone, and so is
deploy.authelia.hostClientSecretDir, which only they read. The publisher keeps
its store identity, the secret-publisher leaf. The host hands the leaf and the
store's CA into the container as nspawn system credentials, and the unit loads
them; where this host mints the leaf, the container waits for swarm-bao-pki.
Authelia does not wait for the publisher, which retries every 30 seconds while
the store is down.
The container also runs the journal forwarder the other service containers
run, pushing to a receiver of its own on the swarm collector (serviceProducers
swarm-authelia) as a new machine OIDC client (swarm.authelia.otel.clientId)
that authelia registers for itself and the publisher carries to the store. The
fetch unit reads it back under the publisher's leaf, also handed to it as a
system credential, so the swarm-secret-publisher policy gains read on that one
leaf; its stanza keeps create and update, which the exact path would otherwise
take from the services/* prefix. Without the leaf the forwarder is off.
The container drops --link-journal=host, and the host collector stops reading
it. The services' "nothing at <path>" errors name the publisher in authelia's
container.
hive-c0re (`hive-<name>`), swarm-controller and swarm-review-classifier
read their queue client secret from the store once and held it as
`ClientSecret::Value` for the life of the process. After authelia
re-minted a secret and swarm-secret-publish stored the new one, every
later token mint presented the old value and was refused until the
daemon restarted.
`ClientSecret::Stored` replaces `Value`: a `StoredSecret` holds the
secret in memory with a caller-supplied read callback, so the crate
takes no store dependency. When the token endpoint answers 400 or 401,
`mint_token` (and its blocking sibling, used by the controller's OTLP
exporters) re-reads it and, if the store holds a different secret,
mints once more with it. One re-read runs at a time and is spawned so
it outlives a caller that gives up. A re-read that fails or finds the
refused value delays the next one, 5 s doubling to 5 min, so a secret
that stays wrong costs one store read per delay. Logs name the client
id and never the secret.
swarm-nats-auth's `oidc_secret` was the template; its re-read machinery
now sits on `StoredSecret`, so the tree has one copy. The responder
gains the same re-read backoff.
The controller keeps its `IDENTITY` OnceLock: it now holds a
`QueueConfig` whose secret is re-read, and the lazily built vcs-metrics
exporter reads the identity from it.
agent_renewal.rs's module doc said a re-minted agent queue secret only
reaches the agent at its next start; hive-agent reads the store on every
connection attempt after its first, so the doc now says that.
Part of #5017 (slice Q).
A controller that started before the forge's host had published its token
ran without forge access until someone restarted it: on a split-host first
deploy that is a manual step. Now the forge client lives in a slot that is
filled once (`Late<T>`, an `Arc<OnceLock<T>>`):
- `forge::enable` tries the store once at start. On failure it logs once and
re-reads in the background with backoff (30s doubling to a 5-minute cap,
no log per retry), fills the slot and logs once when the token is there.
- The forge passes (#5014's per-hive token mint among them), the config-PR
poll and the webhook registration start from that moment, through
`start_forge`'s callback.
- Job nodes and HTTP handlers read the slot when they run, so they answer
"no forge" before and work after.
A token replaced in the store after the slot is filled still reaches the
controller with its next restart. The round-1 change that shared
`queue_identity::fetch_with_retry` is reverted; nothing else uses it.
Refs #4998
The controller's forge token never entered bao: the forge minted it in its
container, hive-forge-swarm-controller-token copied it to a host file, and the
controller LoadCredential'ed that file. forgeTokenFile defaulted to that path
only where the forge ran, so a controller on any other host had no forge
access unless an operator copied the file by hand.
Now the forge's host publishes it and the controller reads it:
- swarm-bao-forge-publisher (replaces hive-forge-swarm-controller-token)
waits for the in-container token, logs in with its own forge-publisher leaf
and writes it to swarm/controller/swarm-controller/forge/token. It runs on
every forge container start, the old unit's trigger.
- New principal swarm-forge-publisher: leaf minted by glue-bao-tls.nix,
policy create/update on that one path, written by
swarm-bao-forge-publisher-policy, CN reserved as a hive name.
- The controller policy gains read on that path. swarm-controller reads it
at start under its own certificate with the OIDC secret's retry, and runs
without forge access if it still cannot.
- forgeTokenFile, its LoadCredential and the forgeEnv gate are gone;
SWARM_CONTROLLER_FORGE_URL is always set. hostSwarmControllerTokenFile is
removed, and a tmpfiles rule deletes the old host copy on the forge host.
The in-container file stays: the mint unit's only-once guard reads it, and
it is the publisher's source.
Refs #4998
The controller's OIDC client secret (client `swarm-controller`, used for
the queue connection, the auth-bridge bearer and the OTLP push) came from
an operator-placed file, `deploy.swarm-controller.queue.clientSecretFile`,
handed in by `LoadCredential=`.
Now `swarm-secret-publish`, which already copies authelia's minted OIDC
secrets into the store, also publishes this one, to
`swarm/controller/swarm-controller/oidc/client`. That path sits under
`controller/`, which no hive's policy reads. The controller reads it once
at start with its existing store certificate and holds it in memory, as
`swarm_queue_client::ClientSecret::Value`. If the store is down, it
retries for about a minute and then fails the start, so `Restart=` tries
again.
Policy delta: the controller gets `read` on that leaf, and the publisher
gets `create`/`update` on that leaf.
Removed: the `queue.clientSecretFile` option (both spellings, now removed
options with a message), its singleHostSwarm default, the credential and
placeholder, and the path watcher plus its restart oneshot. A controller
without a store identity is now an eval error, because it has no other
way to get the secret.
