drop the one-time migration: seed the store from a leftover file once, leave the file
A leftover plaintext client secret is stored once with -cas=0 when the store holds none, so nothing rotates. A store value wins over a different file. The file is no longer read back, compared or removed, and the migration unit is gone.

### Swarm-level — one of each per swarm

|
||||
| swarm-services root CA (cert + key) | `swarm-bao.nix`'s granting unit, inside the store's `pki` mount | the **key** never leaves the mount; the **cert** lands at `/var/lib/swarm-bao-services-pki/services-root.pem` (0644) and at `/var/lib/hive-tls/swarm-services-root.pem` on every hive | nothing to copy — every hive receives the cert with the leaf it asks the store for, or from `pki/ca/pem` where it fronts no swarm name and needs a store identity |
|
||||
| authelia session, JWT, storage-encryption and OIDC HMAC keys | `authelia-swarm-secrets` in authelia's container. It stores each in the swarm secret store at `swarm/services/swarm-authelia/keys/<name>` when the store holds none: the value of the key an earlier release generated, or a new one when there is no such file. The files stay on disk. While the store's policy doesn't grant the leaf yet, or the store is down, the unit runs on the files. A container with no secret publisher identity generates the files, as before | `/var/lib/authelia-swarm/{session,jwt,storage-encryption,oidc-hmac}.key` | nothing to place: the publisher's store leaf is the one in the row below. A store that stays unreachable on a start with no key file keeps authelia from starting |
|
||||
| authelia OIDC issuer key (RSA) | same unit, same store path (`oidc-issuer`) | `/var/lib/authelia-swarm/oidc-issuer.key` | same — relying parties verify against the **public** half at `/jwks.json` |
|
||||
| swarm appservice registration (`as_token`, `hs_token`) | `swarm-matrix-ctl appservice sync` in `hive-matrix`. The store's pair wins; a store holding none takes the container's own tokens, so the value doesn't change by moving. Only `appservice render` on a container with neither mints a new pair | `/var/lib/swarm-matrix-appservice/{as-token,hs-token,swarm.yaml}` in `hive-matrix`, the last copy `sync` took, which tuwunel starts from; the store path is `swarm/controller/swarm-controller/matrix/appservice-registration` | nothing to place: matrix-ctl's store leaf is the one the container binds. A store that's down leaves the homeserver running on the files |
|
||||
| OIDC client secret, plaintext half | `authelia crypto hash generate --random` | the swarm secret store, at the path its reader fetches: `swarm/hives/<hive>/oidc/client`, `swarm/controller/swarm-controller/oidc/client` or `swarm/services/<client id>/oidc/client`. The bridge reads its own into `/run/swarm-authelia-bridge/client-secret` before each start. A container with no secret publisher identity keeps it in `/var/lib/authelia-swarm/oidc-clients/<id>.secret`; `authelia-swarm-client-secrets` moves the files an earlier release left into the store and removes them | nothing to place: readers fetch it from the store ([how](credentials.md#hive-level-secrets)) |
|
||||
| OIDC client secret, digest half | the same mint | `oidc-clients/<id>.digest` | authelia's own half; merged at runtime via `settingsFiles` |
|
||||
| the swarm collector's copy of its OIDC secret | `swarm-bao-otel-oidc.service` reads it out of the swarm secret store, **on every host that runs the collector and holds a store identity** | `/run/swarm-otel-oidc/<id>.secret` on the host's tmpfs, bind-mounted read-only into the `swarm-otel` container — never on persistent disk, so a reboot fetches it again | same unit, same path — one route, co-located or not. A collector with no store identity has `clientSecretFile == null`, its already-supported unauthenticated-push degrade — see [swarm-level secrets](credentials.md#swarm-level-secrets) |
|
||||
| Grafana's copy of its OIDC secret | `swarm-bao-grafana-oidc.service` reads it out of the swarm secret store, **on every host that runs Grafana** | `/run/swarm-grafana-secrets/<id>.secret` on the host's tmpfs, bind-mounted read-only into the `swarm-grafana` container — never on persistent disk, so a reboot fetches it again | same unit, same path — one route, co-located or not. Nothing for an operator to place beyond this host's store leaf, see [hive-level secrets](credentials.md#hive-level-secrets) |
|
||||
| Grafana's admin password | `swarm-bao-grafana-admin.service` creates it in the swarm secret store at `swarm/services/<grafana client id>/admin/password` when the store holds none, then copies it out, **on every host that runs Grafana**. Grafana's leaf may create that leaf but not update it, so the store keeps the first value, and the secret publisher can't write it. To rotate, run `bao kv metadata delete secret/swarm/services/<grafana client id>/admin/password` with a token that may, such as the root token (Grafana's, the publisher's and the controller's can't), then `systemctl restart swarm-bao-grafana-admin`; a plain `bao kv delete` isn't enough, see [the callout xkey's section](credentials.md#the-queues-callout-xkey) | `/run/swarm-grafana-secrets/admin-password` on the host's tmpfs, bind-mounted read-only into the `swarm-grafana` container, never on persistent disk: `security.admin_password` for a new database, and `grafana cli admin reset-admin-password` in `grafana.service`'s `preStart` for an existing one, on every start | same unit, same path. After a reboot the unit fetches the file again, and Grafana doesn't start until it exists, so it stays down rather than falling back to the upstream default `admin` |
|
||||
| Grafana's metrics bearer | `swarm-bao-grafana-metrics-bearer.service` creates it in the swarm secret store at `swarm/services/<grafana client id>/metrics/bearer` when the store holds none, then copies it out, **on every host that runs Grafana**. Same grant as the admin password, create without update. To rotate, run `bao kv metadata delete secret/swarm/services/<grafana client id>/metrics/bearer` with a token that may, then `systemctl restart swarm-bao-grafana-metrics-bearer` | `/run/swarm-grafana-secrets/metrics-bearer` on the host's tmpfs, bind-mounted read-only into the `swarm-grafana` container, holding `Bearer <value>`: the metrics datasource's `Authorization` header. The logs datasource sends the same header. `swarm-metrics-auth` on the metrics store's host, and a second instance on the log store's host (`swarm-logs-grafana-auth`), read the stored value themselves, each under its own leaf | same unit, same path. The unit restarts Grafana when the file changes |
|
||||
| Grafana's datasource encryption key | `swarm-bao-grafana-secret-key.service` stores it in the swarm secret store at `swarm/services/<grafana client id>/secret-key` when the store holds none, then copies it out, **on every host that runs Grafana**. It stores the key an earlier release generated at `/var/lib/grafana-secret/secret_key` in the container, so the key doesn't change, and mints a new one only on a host with no such file. Same grant as the admin password, create without update. The earlier file stays on disk. While the store's policy doesn't grant the leaf yet, or the store is down, the unit runs Grafana on that file | `/run/swarm-grafana-secrets/secret-key` on the host's tmpfs, bind-mounted read-only into the `swarm-grafana` container: `security.secret_key` | same unit, same path. Grafana doesn't start until the file exists. Changing the key leaves Grafana unable to read the datasource secrets it stored, so never delete the store path to rotate it |
|
||||
| the swarm controller's webhook secret | `swarm-controller` stores it in the swarm secret store at `swarm/controller/swarm-controller/forge/webhook-secret` when the store holds none: the value of `webhook-secret` in its state directory, or a new one when there is no such file. The state directory file stays on disk and is the fallback while the store is unreachable or its policy doesn't grant the path yet | the swarm secret store; the controller holds it in memory and registers the same value with the forge's hooks | nothing to place: the controller's store leaf already exists. A store that stays unreachable on a start with no state directory file leaves the webhook endpoint answering 503 |
|
||||
| the metrics store responder's own store leaf (cert + key) | `signLeaf` in `glue-bao-tls.nix` (`swarm-bao-pki.service`), on the host that runs the secret store, once, subject `deploy.bao.metricsAuthCommonName`. `swarm-bao-metrics-auth-policy.service` writes the `swarm-metrics-auth` role and its read grants on the bearer leaf and on the metrics store forwarder's client secret, nothing else | `/var/lib/swarm-bao-pki/metrics-auth.pem` and `metrics-auth-key.pem` on the store's host, handed to `swarm-metrics-auth` through `LoadCredential` (paths in argv, never values) and read by path by `swarm-victoriametrics-forwarder-oidc` | **the operator** places a leaf with that subject on the metrics store's host and names it in `deploy.victoriametrics.authBaoClientCertFile` / `authBaoClientKeyFile`; evaluation fails naming both until then. If the store is on another host, deploy that host first: the role must exist before the responder's login succeeds, and until it does the gateway refuses every Grafana query (fail closed) |
|
||||
| the secret publisher's store leaf (cert + key) | `signLeaf` in `glue-bao-tls.nix` (`swarm-bao-pki.service`), on the host that runs the secret store, once, subject `deploy.bao.secretPublisherCommonName`. `swarm-bao-secret-publisher-policy.service` writes the `swarm-secret-publisher` role: create and update under `swarm/hives/*`, `swarm/services/*` and the controller's client, and read on the `oidc/client` leaves it mints, the controller's client and authelia's five keys alone | `/var/lib/swarm-bao-pki/secret-publisher.pem` and `secret-publisher-key.pem` on the host, handed into authelia's container as nspawn system credentials, which `authelia-swarm-secrets`, `authelia-swarm-client-secrets`, `swarm-authelia-bridge` and the forwarder's `swarm-journal-forwarder-oidc` load with `LoadCredential`. nspawn won't start authelia's container while a named file is missing | **the operator** copies the leaf to authelia's host, beside the hive's own store leaf, where `glue-secret-publisher-bao-identity.nix` looks, or names it in `deploy.swarm-secret-publisher.baoClientCertFile` / `baoClientKeyFile` |
|
||||
| the swarm controller's copy of its OIDC secret | `swarm-controller` reads it out of the swarm secret store at start, under its own leaf | the daemon's memory only; never on disk | same read, co-located or not. Nothing for an operator to place beyond the controller's store leaf (`deploy.swarm-controller.baoClientCertFile`) |
|
||||
| a hive's copy of its own OIDC secret | hive-c0re reads it out of the swarm secret store when it first connects to the queue, under the hive's own leaf | the daemon's memory only; never on disk | same read, co-located or not. Nothing for an operator to place beyond the hive's store leaf (`deploy.bao.clientCertFile`) |
|
||||
| the hive collector's copy of its hive's OIDC secret | `swarm-bao-hive-otel-oidc.service` reads it out of the swarm secret store under the hive's own leaf, **on every hive that runs the collector and holds that leaf**; the leaf is the source | `/run/hive-otel-oidc/hive-<name>.secret` on the hive's host tmpfs, 0400 root, loaded by `LoadCredential` — never on persistent disk, so a reboot fetches it again | same unit, same path, co-located or not. Nothing for an operator to place beyond the hive's store leaf (`deploy.bao.clientCertFile`). Naming a secret file with `otel.clientSecretFile` instead is legacy for a host without a leaf: the build warns, and the fix is to place the leaf from `/var/lib/swarm-bao-pki/hives/<hive>/` and drop the setting |
|
||||
| the swarm controller's forge token | the forge's `forgejo-swarm-controller-account`, in-container, once | the swarm secret store at `swarm/controller/swarm-controller/forge/token`, written by the mint under the forge publisher's leaf, which the forge container loads as a credential; the controller holds it in memory only. `/var/lib/forgejo/swarm-controller-token-name` in the forge container holds its name, the minter's record that it has minted | nothing to place beyond the controller's store leaf. A forge host without the store needs the publisher's leaf placed (`deploy.bao.forgePublisherClientCertFile`) |
|
||||
| the swarm controller's Grafana token | `swarm-bao-grafana-controller-token.service`, **on the host that runs Grafana**, as Grafana's built-in admin over its socket: it creates the `swarm-controller` service account as a Viewer (and sets it back to Viewer on every run), mints a token for it and writes it to the swarm secret store at `swarm/controller/swarm-controller/grafana/token` under Grafana's leaf. Re-run every ten minutes: it keeps a stored token Grafana accepts, and replaces one Grafana refuses with 401 (or a missing one), deleting every other token of that account first | the swarm secret store only; the controller reads it for `GET /api/alerts` and holds it in memory, re-reading the store once when Grafana answers 401 | nothing to place: Grafana's leaf is already required to run Grafana. Until the unit has run, `/api/alerts` answers 503 naming the empty path |
|
||||
| an agent's API-key environment (`ANTHROPIC_API_KEY`, `ANTHROPIC_BASE_URL`, an ACP provider key) | `hive-agent-backend-env.service`, in the agent's container, on an agent with a store that uses `useApiKey` or the `acp` runtime. When the store holds nothing at `swarm/agents/<agent>/backend-env` and `backendEnvironmentFile` is a non-empty file, it creates the leaf with the file's exact bytes and `-cas=0`, under the agent's own leaf, which may create that path and not update it. It never rotates a value and never rewrites or deletes the file. To set or replace a key, use **set the API-key environment** in the swarm UI (`PUT /api/hives/{hive}/agents/{agent}/backend-env`): `swarm-controller` overwrites the leaf with its own grant, and the store's value then wins over the file. Its **remove** (`DELETE` on the same path) deletes the leaf, and an agent whose file has content then creates it from that file again | the swarm secret store at that path; the unit writes it to `/run/hive-agent-backend-env/env` (tmpfs, `0600`, root), and `hive-agent` and `hive-subagent-daemon` load that after `backendEnvironmentFile` as `EnvironmentFile=` | the same unit, same path. A variable in the store wins over the same one in the file. With the store down at a start, the file alone carries the agent, as it did before the store held a copy; with an older hive build the agent ignores the leaf and keeps reading the file |
|
||||
| an agent's proxy settings (`HTTPS_PROXY`, `HTTP_PROXY`, `NO_PROXY`, the credential in the proxy URL) | `hive-agent-proxy-credential.service`, in the agent's container, as the agent user, at start and every 10 minutes: it reads `swarm/agents/<agent>/proxy-credential` under the agent's own leaf and builds the file from it. It writes nothing while the path holds nothing or the hive's facts name no squid | `/run/hive-agent-proxy-credential/proxy.env` (tmpfs, `0600`, the agent user); the harness, its bash tool, the subagents, the MCP servers and the pollers load it as `EnvironmentFile=-` and read it when they start | With no credential, or on a hive that writes no `HIVE_SQUID_PROXY` and `HIVE_EGRESS_NO_PROXY` fact, nothing writes the file and a unit has no proxy variable and reaches the internet directly. A failed read keeps the file already in place. A unit started before the file appeared goes direct until its next start. The credential is also in the environment of every process those units start, so `env` in the agent's shell prints it |
|
||||
| an agent's claude login (`.credentials.json`) | `swarm-claude-login.service`, in its container, when an operator completes `claude auth login` from the agent's card in the swarm UI; it stores the file as a new version at `swarm/agents/<agent>/claude-credentials` under its own leaf, which may create and update that path and read nothing under an agent | the swarm secret store at that path; the agent's `hive-agent` reads it under the agent's own leaf every 30 seconds while it waits for a login and writes it to `~/.claude/.credentials.json` | the same read, co-located or not; nothing for an operator to place beyond the agent's store leaf. When the store's copy and the agent's differ the KV version decides: the agent installs only a version newer than the last it installed (`claude-credentials-version` under the harness dir), because claude rotates the refresh token in its own copy and the stored one goes stale. The agent ignores a stale or equal version, and a relogin writes a newer one — [claude-login.md](claude-login.md) |
|
||||
| the queue responder's copy of its OIDC secret | the responder reads it out of the swarm secret store itself as it starts, under its own leaf, and again when authelia refuses it | the daemon's memory only; never on disk | same read, wherever authelia runs. Nothing for an operator to place beyond the responder's store leaf (`deploy.nats.authBaoClientCertFile`) |
|
||||
| the queue container's journal forwarder's copy of the queue's OIDC secret | `swarm-journal-forwarder-oidc.service` inside the `swarm-nats` container reads it out of the swarm secret store under the responder's store leaf, and again every 10 minutes | `/run/swarm-journal-forwarder-oidc/client-secret` on the container's tmpfs, root `0400`, never on persistent disk; `LoadCredential` hands it to the collector | same unit, same path. After a reboot the collector restarts until the file exists, then resumes from its saved journal cursor. Nothing for an operator to place beyond the responder's store leaf (`deploy.nats.authBaoClientCertFile`) |
|
||||
| the CI runner, Grafana, log store, cache, forge and homeserver containers' journal forwarders' OIDC secrets | `swarm-journal-forwarder-oidc.service` inside each container reads its forwarder client's secret (`swarm.<service>.otel.clientId`) out of the swarm secret store under the store leaf the host already holds for that service, handed in as a system credential (bound in read-only, for the homeserver's), and again every 10 minutes | `/run/swarm-journal-forwarder-oidc/client-secret` on the container's tmpfs, root `0400`, never on persistent disk; `LoadCredential` hands it to the collector | same unit, same path. Nothing for an operator to place beyond those leaves (`deploy.bao.ciRunnerClientCertFile`, `deploy.bao.grafanaOidcClientCertFile`, `deploy.victorialogs.authBaoClientCertFile`, `deploy.bao.forgePublisherClientCertFile`, `deploy.bao.atticClientCertFile`, `deploy.matrix.ctlBaoClientCertFile`) |
|
||||
| the metrics store container's journal forwarder's OIDC secret | `swarm-victoriametrics-forwarder-oidc.service` on the store's host reads its forwarder client's secret (`swarm.victoriametrics.otel.clientId`) out of the swarm secret store under the metrics store responder's leaf, and again every 10 minutes: the container has no network to reach the store | `/run/swarm-victoriametrics-forwarder-oidc/<id>.secret` on the host (tmpfs), root `0400`, never on persistent disk; bound into the container read-only, where `LoadCredential` hands it to the collector | same unit, same path. Nothing for an operator to place beyond that leaf (`deploy.victoriametrics.authBaoClientCertFile`) |
|
||||
| the CI run poller's forge token | `swarm-controller`, with the forge's admin API, for its `ci-metrics` account, at start and in a five-minute pass | the swarm secret store at `swarm/services/ci-metrics/forge/token`; `swarm-ci-metrics` reads it once per pass under its own leaf and holds it in memory for that pass. When the store's token no longer matches the forge's, the controller's next pass mints a new one; until then the poller's forge calls answer 401, the unit fails and no cursor moves | nothing to place beyond the poller's leaf (`deploy.bao.ciMetricsClientCertFile`), on a host without the store |
|
||||
| the CI run poller's copy of its OIDC secret | authelia's mint, which creates it in the swarm secret store | `swarm-ci-metrics` reads `swarm/services/<swarm.ci-metrics.clientId>/oidc/client` once per pass under its own leaf, and again when authelia refuses it; memory only. While it differs from authelia's, the token request fails, nothing gets pushed and no cursor moves | same leaf, nothing else |
|
||||
| authelia's container's journal forwarder's OIDC secret | authelia's mint, in its container, like every client's secret (`swarm.authelia.otel.clientId`). It creates it at `swarm/services/<id>/oidc/client`, and `swarm-journal-forwarder-oidc.service` in the same container reads it back under the secret publisher's leaf, at start and every 10 minutes | `/run/swarm-journal-forwarder-oidc/client-secret` on the container's tmpfs, root `0400`; `LoadCredential` hands it to the collector. | none: the forwarder runs only in authelia's container, and is off there without the publisher's leaf |
|
||||
| authelia subject store | `swarmctl` and `swarm-authelia-bridge` | `users.yml` — one file, read and written by both | `swarmctl`, on the host that runs authelia |
|
||||
| wireguard private key | **the operator** — `wg genkey` | whatever `deploy.wireguard.privateKeyFile` names | always operator-provided; nothing generates this for you |
|
||||
| queue auth-callout nkeys (user seed + account seed) | `swarm-nats-auth ensure-callout-keys`, run by `swarm-bao-nats-callout-xkey` on the queue's host when the store holds no seed; the verb stores a seed it finds at `/var/lib/swarm-nats-callout/{callout-user,issuer}.seed` as is, then removes the file | the swarm secret store: the seeds at `swarm/services/swarm-nats/callout/{user,issuer}-seed`, read by the `swarm-nats-auth` role alone; the public halves at `swarm/public/swarm-nats/callout-{user,issuer}` | nothing to place beyond the responder's store leaf (`deploy.nats.authBaoClientCertFile`) |
|
||||
| queue auth-callout xkey (curve seed) | `swarm-nats-auth ensure-callout-keys`, run by `swarm-bao-nats-callout-xkey` on the queue's host when the store holds no seed | the swarm secret store: the seed at `swarm/services/swarm-nats/callout/xkey-seed`, read by the `swarm-nats-auth` role alone; the public half at `swarm/public/swarm-nats/callout-xkey` | nothing to place beyond the responder's store leaf (`deploy.nats.authBaoClientCertFile`) |
|
||||
| the queue's TLS key, copied for the gateway's `/metrics` vhost | `swarm-nats-gateway-cert.service` on the queue's host, where the gateway uses self-signed TLS: a copy of the queue's bao-PKI TLS leaf (`/var/lib/swarm-nats-tls/`) once `swarm-bao-nats-tls` has issued it, else a throwaway 30-day self-signed pair for the queue's name until then | `/var/lib/swarm-nats-gateway-tls/{cert,key}.pem`; the key is `0640` group `nginx`, read by nginx for the queue's `/metrics` vhost. The queue's own key stays `0600` root | the copy is redone on each leaf renewal (`swarm-bao-nats-tls` starts the unit, which queues a non-blocking nginx reload when nginx is running); a restart before any leaf exists keeps the pair already there. Until `swarm-bao-nats-tls` issues the leaf the vhost serves the throwaway cert, so the collector's scrape fails TLS. Nothing for an operator to place |
|
||||
| the secret store's own contents | openbao, on first `bao operator init` — **an operator action, not a unit** | inside the `swarm-bao` container, at its own `/var/lib/openbao`, kept across rebuilds by `ephemeral = false`. ⚠️ **Not a host path**: `nixos-container destroy swarm-bao` takes the raft data with it, so back up the container's tree, not `/var/lib/`. Only the store's TLS material (`/var/lib/swarm-bao-tls`) and its PKCS11 token (`/var/lib/swarm-bao-token`) are host-level | n/a — there is one store; a hive elsewhere is a _client_ of it and holds none of this |
|
||||
| the secret store's unseal material | the HSM/TPM under `deploy.bao.seal = "pkcs11"`; openbao itself under `"shamir"` | in the token; or held by whoever ran `bao operator init`, which is what `"shamir"` means and why it's stated rather than inferred | n/a — only the host running the store seals anything |

|

| swarm-services root CA (cert + key) | `swarm-bao.nix`'s granting unit, inside the store's `pki` mount | the **key** never leaves the mount; the **cert** lands at `/var/lib/swarm-bao-services-pki/services-root.pem` (0644) and at `/var/lib/hive-tls/swarm-services-root.pem` on every hive | nothing to copy — every hive receives the cert with the leaf it asks the store for, or from `pki/ca/pem` where it fronts no swarm name and needs a store identity |
|
||||
| authelia session, JWT, storage-encryption and OIDC HMAC keys | `authelia-swarm-secrets` in authelia's container. It stores each in the swarm secret store at `swarm/services/swarm-authelia/keys/<name>` when the store holds none: the value of the key an earlier release generated, or a new one when there is no such file. The files stay on disk. While the store's policy doesn't grant the leaf yet, or the store is down, the unit runs on the files. A container with no secret publisher identity generates the files, as before | `/var/lib/authelia-swarm/{session,jwt,storage-encryption,oidc-hmac}.key` | nothing to place: the publisher's store leaf is the one in the row below. A store that stays unreachable on a start with no key file keeps authelia from starting |
|
||||
| authelia OIDC issuer key (RSA) | same unit, same store path (`oidc-issuer`) | `/var/lib/authelia-swarm/oidc-issuer.key` | same — relying parties verify against the **public** half at `/jwks.json` |
|
||||
| swarm appservice registration (`as_token`, `hs_token`) | `swarm-matrix-ctl appservice sync` in `hive-matrix`. The store's pair wins; a store holding none takes the container's own tokens, so the value doesn't change by moving. Only `appservice render` on a container with neither mints a new pair | `/var/lib/swarm-matrix-appservice/{as-token,hs-token,swarm.yaml}` in `hive-matrix`, the last copy `sync` took, which tuwunel starts from; the store path is `swarm/controller/swarm-controller/matrix/appservice-registration` | nothing to place: matrix-ctl's store leaf is the one the container binds. A store that's down leaves the homeserver running on the files |
|
||||
| OIDC client secret, plaintext half | `authelia crypto hash generate --random` | the swarm secret store, at the path its reader fetches: `swarm/hives/<hive>/oidc/client`, `swarm/controller/swarm-controller/oidc/client` or `swarm/services/<client id>/oidc/client`. The bridge reads its own into `/run/swarm-authelia-bridge/client-secret` before each start. A container with no secret publisher identity keeps it in `/var/lib/authelia-swarm/oidc-clients/<id>.secret`; a file an earlier release left seeds the store once when it holds no value, and stays unused | nothing to place: readers fetch it from the store ([how](credentials.md#hive-level-secrets)) |
|
||||
| OIDC client secret, digest half | the same mint | `oidc-clients/<id>.digest` | authelia's own half; merged at runtime via `settingsFiles` |
|
||||
| the swarm collector's copy of its OIDC secret | `swarm-bao-otel-oidc.service` reads it out of the swarm secret store, **on every host that runs the collector and holds a store identity** | `/run/swarm-otel-oidc/<id>.secret` on the host's tmpfs, bind-mounted read-only into the `swarm-otel` container — never on persistent disk, so a reboot fetches it again | same unit, same path — one route, co-located or not. A collector with no store identity has `clientSecretFile == null`, its already-supported unauthenticated-push degrade — see [swarm-level secrets](credentials.md#swarm-level-secrets) |
|
||||
| Grafana's copy of its OIDC secret | `swarm-bao-grafana-oidc.service` reads it out of the swarm secret store, **on every host that runs Grafana** | `/run/swarm-grafana-secrets/<id>.secret` on the host's tmpfs, bind-mounted read-only into the `swarm-grafana` container — never on persistent disk, so a reboot fetches it again | same unit, same path — one route, co-located or not. Nothing for an operator to place beyond this host's store leaf, see [hive-level secrets](credentials.md#hive-level-secrets) |
|
||||
| Grafana's admin password | `swarm-bao-grafana-admin.service` creates it in the swarm secret store at `swarm/services/<grafana client id>/admin/password` when the store holds none, then copies it out, **on every host that runs Grafana**. Grafana's leaf may create that leaf but not update it, so the store keeps the first value, and the secret publisher can't write it. To rotate, run `bao kv metadata delete secret/swarm/services/<grafana client id>/admin/password` with a token that may, such as the root token (Grafana's, the publisher's and the controller's can't), then `systemctl restart swarm-bao-grafana-admin`; a plain `bao kv delete` isn't enough, see [the callout xkey's section](credentials.md#the-queues-callout-xkey) | `/run/swarm-grafana-secrets/admin-password` on the host's tmpfs, bind-mounted read-only into the `swarm-grafana` container, never on persistent disk: `security.admin_password` for a new database, and `grafana cli admin reset-admin-password` in `grafana.service`'s `preStart` for an existing one, on every start | same unit, same path. After a reboot the unit fetches the file again, and Grafana doesn't start until it exists, so it stays down rather than falling back to the upstream default `admin` |
|
||||
| Grafana's metrics bearer | `swarm-bao-grafana-metrics-bearer.service` creates it in the swarm secret store at `swarm/services/<grafana client id>/metrics/bearer` when the store holds none, then copies it out, **on every host that runs Grafana**. Same grant as the admin password, create without update. To rotate, run `bao kv metadata delete secret/swarm/services/<grafana client id>/metrics/bearer` with a token that may, then `systemctl restart swarm-bao-grafana-metrics-bearer` | `/run/swarm-grafana-secrets/metrics-bearer` on the host's tmpfs, bind-mounted read-only into the `swarm-grafana` container, holding `Bearer <value>`: the metrics datasource's `Authorization` header. The logs datasource sends the same header. `swarm-metrics-auth` on the metrics store's host, and a second instance on the log store's host (`swarm-logs-grafana-auth`), read the stored value themselves, each under its own leaf | same unit, same path. The unit restarts Grafana when the file changes |
|
||||
| Grafana's datasource encryption key | `swarm-bao-grafana-secret-key.service` stores it in the swarm secret store at `swarm/services/<grafana client id>/secret-key` when the store holds none, then copies it out, **on every host that runs Grafana**. It stores the key an earlier release generated at `/var/lib/grafana-secret/secret_key` in the container, so the key doesn't change, and mints a new one only on a host with no such file. Same grant as the admin password, create without update. The earlier file stays on disk. While the store's policy doesn't grant the leaf yet, or the store is down, the unit runs Grafana on that file | `/run/swarm-grafana-secrets/secret-key` on the host's tmpfs, bind-mounted read-only into the `swarm-grafana` container: `security.secret_key` | same unit, same path. Grafana doesn't start until the file exists. Changing the key leaves Grafana unable to read the datasource secrets it stored, so never delete the store path to rotate it |
|
||||
| the swarm controller's webhook secret | `swarm-controller` stores it in the swarm secret store at `swarm/controller/swarm-controller/forge/webhook-secret` when the store holds none: the value of `webhook-secret` in its state directory, or a new one when there is no such file. The state directory file stays on disk and is the fallback while the store is unreachable or its policy doesn't grant the path yet | the swarm secret store; the controller holds it in memory and registers the same value with the forge's hooks | nothing to place: the controller's store leaf already exists. A store that stays unreachable on a start with no state directory file leaves the webhook endpoint answering 503 |
|
||||
| the metrics store responder's own store leaf (cert + key) | `signLeaf` in `glue-bao-tls.nix` (`swarm-bao-pki.service`), on the host that runs the secret store, once, subject `deploy.bao.metricsAuthCommonName`. `swarm-bao-metrics-auth-policy.service` writes the `swarm-metrics-auth` role and its read grants on the bearer leaf and on the metrics store forwarder's client secret, nothing else | `/var/lib/swarm-bao-pki/metrics-auth.pem` and `metrics-auth-key.pem` on the store's host, handed to `swarm-metrics-auth` through `LoadCredential` (paths in argv, never values) and read by path by `swarm-victoriametrics-forwarder-oidc` | **the operator** places a leaf with that subject on the metrics store's host and names it in `deploy.victoriametrics.authBaoClientCertFile` / `authBaoClientKeyFile`; evaluation fails naming both until then. If the store is on another host, deploy that host first: the role must exist before the responder's login succeeds, and until it does the gateway refuses every Grafana query (fail closed) |
|
||||
| the secret publisher's store leaf (cert + key) | `signLeaf` in `glue-bao-tls.nix` (`swarm-bao-pki.service`), on the host that runs the secret store, once, subject `deploy.bao.secretPublisherCommonName`. `swarm-bao-secret-publisher-policy.service` writes the `swarm-secret-publisher` role: create and update under `swarm/hives/*`, `swarm/services/*` and the controller's client, and read on the `oidc/client` leaves it mints, the controller's client and authelia's five keys alone | `/var/lib/swarm-bao-pki/secret-publisher.pem` and `secret-publisher-key.pem` on the host, handed into authelia's container as nspawn system credentials, which `authelia-swarm-secrets`, `swarm-authelia-bridge` and the forwarder's `swarm-journal-forwarder-oidc` load with `LoadCredential`. nspawn won't start authelia's container while a named file is missing | **the operator** copies the leaf to authelia's host, beside the hive's own store leaf, where `glue-secret-publisher-bao-identity.nix` looks, or names it in `deploy.swarm-secret-publisher.baoClientCertFile` / `baoClientKeyFile` |
|
||||
| the swarm controller's copy of its OIDC secret | `swarm-controller` reads it out of the swarm secret store at start, under its own leaf | the daemon's memory only; never on disk | same read, co-located or not. Nothing for an operator to place beyond the controller's store leaf (`deploy.swarm-controller.baoClientCertFile`) |
|
||||
| a hive's copy of its own OIDC secret | hive-c0re reads it out of the swarm secret store when it first connects to the queue, under the hive's own leaf | the daemon's memory only; never on disk | same read, co-located or not. Nothing for an operator to place beyond the hive's store leaf (`deploy.bao.clientCertFile`) |
|
||||
| the hive collector's copy of its hive's OIDC secret | `swarm-bao-hive-otel-oidc.service` reads it out of the swarm secret store under the hive's own leaf, **on every hive that runs the collector and holds that leaf**; the leaf is the source | `/run/hive-otel-oidc/hive-<name>.secret` on the hive's host tmpfs, 0400 root, loaded by `LoadCredential` — never on persistent disk, so a reboot fetches it again | same unit, same path, co-located or not. Nothing for an operator to place beyond the hive's store leaf (`deploy.bao.clientCertFile`). Naming a secret file with `otel.clientSecretFile` instead is legacy for a host without a leaf: the build warns, and the fix is to place the leaf from `/var/lib/swarm-bao-pki/hives/<hive>/` and drop the setting |
|
||||
| the swarm controller's forge token | the forge's `forgejo-swarm-controller-account`, in-container, once | the swarm secret store at `swarm/controller/swarm-controller/forge/token`, written by the mint under the forge publisher's leaf, which the forge container loads as a credential; the controller holds it in memory only. `/var/lib/forgejo/swarm-controller-token-name` in the forge container holds its name, the minter's record that it has minted | nothing to place beyond the controller's store leaf. A forge host without the store needs the publisher's leaf placed (`deploy.bao.forgePublisherClientCertFile`) |
|
||||
| the swarm controller's Grafana token | `swarm-bao-grafana-controller-token.service`, **on the host that runs Grafana**, as Grafana's built-in admin over its socket: it creates the `swarm-controller` service account as a Viewer (and sets it back to Viewer on every run), mints a token for it and writes it to the swarm secret store at `swarm/controller/swarm-controller/grafana/token` under Grafana's leaf. Re-run every ten minutes: it keeps a stored token Grafana accepts, and replaces one Grafana refuses with 401 (or a missing one), deleting every other token of that account first | the swarm secret store only; the controller reads it for `GET /api/alerts` and holds it in memory, re-reading the store once when Grafana answers 401 | nothing to place: Grafana's leaf is already required to run Grafana. Until the unit has run, `/api/alerts` answers 503 naming the empty path |
|
||||
| an agent's API-key environment (`ANTHROPIC_API_KEY`, `ANTHROPIC_BASE_URL`, an ACP provider key) | `hive-agent-backend-env.service`, in the agent's container, on an agent with a store that uses `useApiKey` or the `acp` runtime. When the store holds nothing at `swarm/agents/<agent>/backend-env` and `backendEnvironmentFile` is a non-empty file, it creates the leaf with the file's exact bytes and `-cas=0`, under the agent's own leaf, which may create that path and not update it. It never rotates a value and never rewrites or deletes the file. To set or replace a key, use **set the API-key environment** in the swarm UI (`PUT /api/hives/{hive}/agents/{agent}/backend-env`): `swarm-controller` overwrites the leaf with its own grant, and the store's value then wins over the file. Its **remove** (`DELETE` on the same path) deletes the leaf, and an agent whose file has content then creates it from that file again | the swarm secret store at that path; the unit writes it to `/run/hive-agent-backend-env/env` (tmpfs, `0600`, root), and `hive-agent` and `hive-subagent-daemon` load that after `backendEnvironmentFile` as `EnvironmentFile=` | the same unit, same path. A variable in the store wins over the same one in the file. With the store down at a start, the file alone carries the agent, as it did before the store held a copy; with an older hive build the agent ignores the leaf and keeps reading the file |
|
||||
| an agent's proxy settings (`HTTPS_PROXY`, `HTTP_PROXY`, `NO_PROXY`, the credential in the proxy URL) | `hive-agent-proxy-credential.service`, in the agent's container, as the agent user, at start and every 10 minutes: it reads `swarm/agents/<agent>/proxy-credential` under the agent's own leaf and builds the file from it. It writes nothing while the path holds nothing or the hive's facts name no squid | `/run/hive-agent-proxy-credential/proxy.env` (tmpfs, `0600`, the agent user); the harness, its bash tool, the subagents, the MCP servers and the pollers load it as `EnvironmentFile=-` and read it when they start | With no credential, or on a hive that writes no `HIVE_SQUID_PROXY` and `HIVE_EGRESS_NO_PROXY` fact, nothing writes the file and a unit has no proxy variable and reaches the internet directly. A failed read keeps the file already in place. A unit started before the file appeared goes direct until its next start. The credential is also in the environment of every process those units start, so `env` in the agent's shell prints it |
|
||||
| an agent's claude login (`.credentials.json`) | `swarm-claude-login.service`, in its container, when an operator completes `claude auth login` from the agent's card in the swarm UI; it stores the file as a new version at `swarm/agents/<agent>/claude-credentials` under its own leaf, which may create and update that path and read nothing under an agent | the swarm secret store at that path; the agent's `hive-agent` reads it under the agent's own leaf every 30 seconds while it waits for a login and writes it to `~/.claude/.credentials.json` | the same read, co-located or not; nothing for an operator to place beyond the agent's store leaf. When the store's copy and the agent's differ the KV version decides: the agent installs only a version newer than the last it installed (`claude-credentials-version` under the harness dir), because claude rotates the refresh token in its own copy and the stored one goes stale. The agent ignores a stale or equal version, and a relogin writes a newer one — [claude-login.md](claude-login.md) |
|
||||
| the queue responder's copy of its OIDC secret | the responder reads it out of the swarm secret store itself as it starts, under its own leaf, and again when authelia refuses it | the daemon's memory only; never on disk | same read, wherever authelia runs. Nothing for an operator to place beyond the responder's store leaf (`deploy.nats.authBaoClientCertFile`) |
|
||||
| the queue container's journal forwarder's copy of the queue's OIDC secret | `swarm-journal-forwarder-oidc.service` inside the `swarm-nats` container reads it out of the swarm secret store under the responder's store leaf, and again every 10 minutes | `/run/swarm-journal-forwarder-oidc/client-secret` on the container's tmpfs, root `0400`, never on persistent disk; `LoadCredential` hands it to the collector | same unit, same path. After a reboot the collector restarts until the file exists, then resumes from its saved journal cursor. Nothing for an operator to place beyond the responder's store leaf (`deploy.nats.authBaoClientCertFile`) |
|
||||
| the CI runner, Grafana, log store, cache, forge and homeserver containers' journal forwarders' OIDC secrets | `swarm-journal-forwarder-oidc.service` inside each container reads its forwarder client's secret (`swarm.<service>.otel.clientId`) out of the swarm secret store under the store leaf the host already holds for that service, handed in as a system credential (bound in read-only, for the homeserver's), and again every 10 minutes | `/run/swarm-journal-forwarder-oidc/client-secret` on the container's tmpfs, root `0400`, never on persistent disk; `LoadCredential` hands it to the collector | same unit, same path. Nothing for an operator to place beyond those leaves (`deploy.bao.ciRunnerClientCertFile`, `deploy.bao.grafanaOidcClientCertFile`, `deploy.victorialogs.authBaoClientCertFile`, `deploy.bao.forgePublisherClientCertFile`, `deploy.bao.atticClientCertFile`, `deploy.matrix.ctlBaoClientCertFile`) |
|
||||
| the metrics store container's journal forwarder's OIDC secret | `swarm-victoriametrics-forwarder-oidc.service` on the store's host reads its forwarder client's secret (`swarm.victoriametrics.otel.clientId`) out of the swarm secret store under the metrics store responder's leaf, and again every 10 minutes: the container has no network to reach the store | `/run/swarm-victoriametrics-forwarder-oidc/<id>.secret` on the host (tmpfs), root `0400`, never on persistent disk; bound into the container read-only, where `LoadCredential` hands it to the collector | same unit, same path. Nothing for an operator to place beyond that leaf (`deploy.victoriametrics.authBaoClientCertFile`) |
|
||||
| the CI run poller's forge token | `swarm-controller`, with the forge's admin API, for its `ci-metrics` account, at start and in a five-minute pass | the swarm secret store at `swarm/services/ci-metrics/forge/token`; `swarm-ci-metrics` reads it once per pass under its own leaf and holds it in memory for that pass. When the store's token no longer matches the forge's, the controller's next pass mints a new one; until then the poller's forge calls answer 401, the unit fails and no cursor moves | nothing to place beyond the poller's leaf (`deploy.bao.ciMetricsClientCertFile`), on a host without the store |
|
||||
| the CI run poller's copy of its OIDC secret | authelia's mint, which creates it in the swarm secret store | `swarm-ci-metrics` reads `swarm/services/<swarm.ci-metrics.clientId>/oidc/client` once per pass under its own leaf, and again when authelia refuses it; memory only. While it differs from authelia's, the token request fails, nothing gets pushed and no cursor moves | same leaf, nothing else |
|
||||
| authelia's container's journal forwarder's OIDC secret | authelia's mint, in its container, like every client's secret (`swarm.authelia.otel.clientId`). It creates it at `swarm/services/<id>/oidc/client`, and `swarm-journal-forwarder-oidc.service` in the same container reads it back under the secret publisher's leaf, at start and every 10 minutes | `/run/swarm-journal-forwarder-oidc/client-secret` on the container's tmpfs, root `0400`; `LoadCredential` hands it to the collector. | none: the forwarder runs only in authelia's container, and is off there without the publisher's leaf |
|
||||
| authelia subject store | `swarmctl` and `swarm-authelia-bridge` | `users.yml` — one file, read and written by both | `swarmctl`, on the host that runs authelia |
|
||||
| wireguard private key | **the operator** — `wg genkey` | whatever `deploy.wireguard.privateKeyFile` names | always operator-provided; nothing generates this for you |
|
||||
| queue auth-callout nkeys (user seed + account seed) | `swarm-nats-auth ensure-callout-keys`, run by `swarm-bao-nats-callout-xkey` on the queue's host when the store holds no seed; the verb stores a seed it finds at `/var/lib/swarm-nats-callout/{callout-user,issuer}.seed` as is, then removes the file | the swarm secret store: the seeds at `swarm/services/swarm-nats/callout/{user,issuer}-seed`, read by the `swarm-nats-auth` role alone; the public halves at `swarm/public/swarm-nats/callout-{user,issuer}` | nothing to place beyond the responder's store leaf (`deploy.nats.authBaoClientCertFile`) |
|
||||
| queue auth-callout xkey (curve seed) | `swarm-nats-auth ensure-callout-keys`, run by `swarm-bao-nats-callout-xkey` on the queue's host when the store holds no seed | the swarm secret store: the seed at `swarm/services/swarm-nats/callout/xkey-seed`, read by the `swarm-nats-auth` role alone; the public half at `swarm/public/swarm-nats/callout-xkey` | nothing to place beyond the responder's store leaf (`deploy.nats.authBaoClientCertFile`) |
|
||||
| the queue's TLS key, copied for the gateway's `/metrics` vhost | `swarm-nats-gateway-cert.service` on the queue's host, where the gateway uses self-signed TLS: a copy of the queue's bao-PKI TLS leaf (`/var/lib/swarm-nats-tls/`) once `swarm-bao-nats-tls` has issued it, else a throwaway 30-day self-signed pair for the queue's name until then | `/var/lib/swarm-nats-gateway-tls/{cert,key}.pem`; the key is `0640` group `nginx`, read by nginx for the queue's `/metrics` vhost. The queue's own key stays `0600` root | the copy is redone on each leaf renewal (`swarm-bao-nats-tls` starts the unit, which queues a non-blocking nginx reload when nginx is running); a restart before any leaf exists keeps the pair already there. Until `swarm-bao-nats-tls` issues the leaf the vhost serves the throwaway cert, so the collector's scrape fails TLS. Nothing for an operator to place |
|
||||
| the secret store's own contents | openbao, on first `bao operator init` — **an operator action, not a unit** | inside the `swarm-bao` container, at its own `/var/lib/openbao`, kept across rebuilds by `ephemeral = false`. ⚠️ **Not a host path**: `nixos-container destroy swarm-bao` takes the raft data with it, so back up the container's tree, not `/var/lib/`. Only the store's TLS material (`/var/lib/swarm-bao-tls`) and its PKCS11 token (`/var/lib/swarm-bao-token`) are host-level | n/a — there is one store; a hive elsewhere is a _client_ of it and holds none of this |
|
||||
| the secret store's unseal material | the HSM/TPM under `deploy.bao.seal = "pkcs11"`; openbao itself under `"shamir"` | in the token; or held by whoever ran `bao operator init`, which is what `"shamir"` means and why it's stated rather than inferred | n/a — only the host running the store seals anything |
