The agent's baked default pointed at the PUBLIC admin-UI name
(diskless-server.bitasylum.org), which resolves to the serving host's outbound IP
— unreachable from the fleet LAN. There's no split-horizon to "automate": the
manager agent plane is just another *.fleet.lab, served by the fleet dnsmasq like
boot/nvme/audit.
- serving/.env.example: MGMT_HOST=manager.fleet.lab.
- serving/docker-compose.yml: dnsmasq --address=/${MGMT_HOST}/${SERVER_IP}.
- files/agent/agent.env + main.go default: FLEET_AGENT_MANAGER=manager.fleet.lab:9600.
- server-pki.sh: AGENT_SANS default -> manager.fleet.lab (cert SAN matches the
baked name, so no FLEET_AGENT_SERVER_NAME override).
- docs/TODO #14 gotcha #4 updated: fleet name, not the IP+server-name workaround.
The public diskless-server.bitasylum.org stays the ADMIN-UI name (Traefik/:443).
Verifying the step signer against a real step-ca surfaced two real bugs the
mock signer had hidden, plus made the bench CA actually initialise:
- signer.go: move --not-after from `step ca token` (validity caps ~1h ->
"token validity too long") to `step ca sign` (it is the CERT lifetime).
Without this the step signer never issues a cert.
- dot1x-bench compose: DOCKER_STEPCA_INIT_PASSWORD_FILE pointed at a file that
does not exist at first init (it is an INPUT path), so `step ca init` failed
and never wrote secrets/password. Use DOCKER_STEPCA_INIT_PASSWORD (the value)
which the entrypoint writes to secrets/password, where bootstrap + broker read.
- bootstrap.sh: self-heal the root-owned ./pki Docker auto-creates; detect the
CA password at $STEPPATH/password or secrets/password (varies by image
version); raise authority.claims.maxTLSCertDuration so 720h fleet certs are
allowed (stock cap 24h, which also blocked bootstrap's own RADIUS cert); fix
RADIUS cert paths to write via the /export mount (were host paths run inside
the container, so they never resolved).
- serving stack: add the enrol-broker service (temporary home; nginx already
proxies /enrol/) defaulting to the zero-dependency lab path (mock signer +
insecure loopback admin), with ENROL_* knobs to switch to step + mTLS.
- verify-serving.sh: exercise request -> approve -> cert through the deployed
nginx /enrol/ proxy.
- TODO #11: record the step-signer verification + the two fixes.
Step signer VERIFIED end-to-end against a real step-ca: issued cert chains to
the fleet root, EKU clientAuth, hostnqn derived from serial.
