openbao gains a second listener, `ui`, on 127.0.0.1:<deploy.bao.uiPort>
(default 8204) with TLS off and no client-certificate requirement, and
`ui = true`. The existing listeners are unchanged. An nginx inside the
store's container, on 127.0.0.1:<deploy.bao.uiProxyPort> (default 8206),
forwards only /ui/ and /v1/ to it, redirects / to /ui/, answers 403 on
sys/unseal, sys/seal, sys/step-down, sys/rekey* and sys/generate-root*,
and 404 on everything else.
The gateway on the store's host serves `swarm.bao.ui.domain` (default
bao-ui.<swarm>) behind the authelia auth_request subrequest, proxying to
that nginx; the name joins serviceDomains and localNames like every
other gateway-published swarm service. authelia gets an access_control
rule restricting that name to group:admins, rendered wherever authelia
runs, since the default policy admits any session.
Trade-off, ruled by the operator on the parent issue: the UI listener
asks for no client certificate, so on that door a bao token alone is the
credential.
Three comments and a doc line claimed every API listener demands a
client certificate; they now except the loopback UI listener. The
module-eval case counting declared listeners excludes `ui` by name, as
it already did `metrics`.
On a self-signed gateway, the UI's name is a swarm service name, so its
host requests the services leaf from the store. `swarm-services-cert`
sits Before= and RequiredBy= the gateway's cert import, which nginx
Requires=. On a host whose only swarm name is the UI, that would hold
nginx, and with it the stream passthrough every reader dials, on a login
to a store that may be sealed. hive-tls drops those two edges exactly
when the UI is the only local swarm name: nginx starts on the existing
hive-leaf fallback, and the script's existing re-import reloads nginx
once the leaf issues. Every other host keeps both edges.
An agent's store identity was signed in swarm-controller's memory by a CA
a controller-host unit generated on disk, and the listener never trusted
that CA. Agent leaves now come from the store itself: a `pki-agents` PKI
mount whose root openbao generates internally, so the agent CA's key
never exists outside the store.
- swarm-bao-agent-pki (new, store host, as the bao granter): enables and
tunes the mount, generates the root once (guarded on an empty issuer
list, no replace branch), upserts the `swarm-agent` role (client
certificates named `hive-agent-*` only, 90 days), caches the CA at
/var/lib/swarm-bao-tls/agent-ca.pem and composes the listener bundle.
- The listener's tls_client_ca_file is a new listener-client-ca.pem
(client-ca.pem, then the agent CA). Host cert-auth roles still pin
client-ca.pem, so an agent leaf satisfies no host role. swarm-bao-certs
composes the same bundle before openbao starts.
- openbao reads tls_client_ca_file only at start, so when the bundle
changed after openbao started, swarm-bao-agent-pki restarts
openbao.service in the container; under `seal = "shamir"` it prints
the step instead. Once swarm-bao-certs has a cached CA, later boots
start openbao with it and do not restart.
- The controller policy gains exactly `update` on
pki-agents/issue/swarm-agent. mint_and_verify now asks that role for
the leaf (the store generates the key), writes the agent's cert-auth
role pinning the issuing CA bao returned, and writes the agent's
policy as render_agent alone: the hive-shared queue credential stanza
is gone.
- deploy.bao.agentPkiRoleName (must start `swarm-`, asserted with the
other pki role names); swarm-controller gets
SWARM_CONTROLLER_AGENT_PKI_MOUNT/_ROLE from the deploy.bao options.
Deleted: swarm-controller-agent-ca and its options (agentCaFile,
agentCaKeyFile), env, LoadCredential entries and assertion;
agent_identity's Authority, rcgen signing and validity window; the
rcgen and time dependencies of swarm-controller (rcgen leaves the
workspace); policy::render_agent_with_queue and its tests. The CN-prefix
assertion policy.rs said was owed is not: agent and host roles pin
different CAs.
Migration is re-creating each agent after deploy; that overwrites the
stale role and policy.
Closes#4756
The single module-eval derivation forced ~62 full nixosSystem
fixtures live at once to compute its cases list: 10.6GB peak RSS /
5m25s to evaluate, by far the dominant cost in nix flake check.
Splits it into 21 independent checks.module-eval-* derivations
(1-7 fixtures each) sharing builders/helpers via module-eval/lib.nix,
so no single derivation needs more than a handful of fixtures live
at once. A few cases spanning two clusters carry a small duplicated
fixture rather than threading shared state through lib.nix.
