Four fixes from the on-host agent bring-up:
1. Bake the real fleet CA into the image. New `fleet_ca` build var (default =
the committed placeholder) file-provisions the trust anchor to
/etc/dot1x/radius-ca.pem — used by wpa_supplicant (RADIUS) AND the fleet-agent
(verify the manager). CI materializes a FLEET_CA secret to a runner-temp file
and passes -var fleet_ca; unset => placeholder (lab). No CA material committed.
2. server-pki.sh installs the agent CLIENT CA as root+intermediate (not root
only). Host TPM certs are leaf-only in NV and signed by the step-ca
intermediate, so a root-only client CA makes the manager advertise only the
root in its CertificateRequest -> Go clients send no cert ("tls: certificate
required") and it couldn't verify a leaf-only cert anyway. bootstrap.sh now
exports intermediate_ca.crt so FLEET_CA_INTERMEDIATE resolves.
3. New `fleet-manager register-host <serial> [-name] [-hostnqn]` subcommand:
seeds/updates an inventory record for a host enrolled out of band (bench
broker, migrated fleet) through the real store, so its agent stream is
accepted. The manual counterpart to the authorise-approve flow.
4. The agent surfaces the authoritative recv-side gRPC status instead of the
bare io.EOF gRPC returns on the send side when the server ends the stream —
so "host is not enrolled" (PermissionDenied) shows up instead of "EOF".
Follow the code removal through the rest of the tree now that Traefik owns UI TLS:
- compose: drop FLEET_MGR_ADMIN_BEHIND_PROXY + ADMIN_CERT/_KEY from the manager
env; correct the ./pki mount comment (agent + broker certs only).
- .env.example: drop the BEHIND_PROXY + cert vars + self-TLS note.
- DEPLOY.md / README: remove the self-TLS "alternative" and the BEHIND_PROXY /
ADMIN_CERT config rows.
- server-pki.sh: point the admin UI cert at Traefik, not ./pki/admin.
- delete serving/fleet-manager/acme/ (the retired ACME side-car).
Complete the deployment story for the server-side control plane:
- docker-compose.yml: private InfluxDB (published to loopback only) + a
host-networked fleet-manager (reaches the loopback enrol-broker on
127.0.0.1:9443 and binds a routable gRPC agent listener, like the broker).
- .env.example: RP origin (diskless-server.bitasylum.org), Influx token/DB
password, cert/PKI paths; the Influx token wires influxdb + manager with
one value.
- server-pki.sh: issue the agent-plane server cert from the fleet CA (step)
and stage the fleet root as the client-verify CA.
- DEPLOY.md: end-to-end runbook — three-cert PKI (fleet-CA agent cert, broker
admin-client cert, Let's Encrypt DNS-01 UI cert), register-admin passkey
bootstrap, compose up, hardware-free smoke test, backups.
- .dockerignore: keep host node_modules/dist/pki/secrets out of the build
context so the embedded SPA is the one built in-image.
- .gitignore: never commit .env / issued PKI / data.
Design docs marked as-built: fleet-management-design.md as-built note
(resolved forks — gRPC bidi transport, InfluxDB metrics, SPA graphs, passkey
admin auth, broker fold-in "alongside"); tpm-enrolment-design.md (broker
fold-in + agent transport fork resolved); TODO.md #14 → partly built, with
the on-host agent + per-host boot-version assignment (#6) called out as the
remaining work.
