Previously `decnet status` on an agent showed every microservice as DOWN
because deploy's auto-spawn was unihost-scoped and the agent CLI gate
hid the per-host commands. Now:
- collect, probe, profiler, sniffer drop out of MASTER_ONLY_COMMANDS
(they run per-host; master-side work stays master-gated).
- mutate stays master-only (it orchestrates swarm-wide respawns).
- decnet/mutator/ excluded from agent tarballs — never invoked there.
- decnet/web exclusion tightened: ship db/ + auth.py + dependencies.py
(profiler needs the repo singleton), drop api.py, swarm_api.py,
ingester.py, router/, templates/.
- Four new systemd unit templates (decnet-collector/prober/profiler/
sniffer) shipped in every enrollment tarball.
- enroll_bootstrap.sh enables + starts all four alongside agent and
forwarder at install time.
- updater restarts the aux units on code push so they pick up the new
release (best-effort — legacy enrollments without the units won't
fail the update).
- status table hides Mutator + API rows in agent mode.
Agents never run the FastAPI master app (decnet/web/) or serve the React
frontend (decnet_web/) — they run decnet.agent, decnet.updater, and
decnet.forwarder, none of which import decnet.web. Shipping the master
tree bloats every enrollment payload and needlessly widens the worker's
attack surface.
Excluded paths are unreachable on the worker (all cli.py imports of
decnet.web are inside master-only command bodies that the agent-mode
gate strips). Tests assert neither tree leaks into the tarball.
Bootstrap used to end with `decnet updater --daemon` which forks and
detaches — invisible to systemctl, no auto-restart, dies on reboot.
Ships a decnet-updater.service template matching the pattern of the
other units (Restart=on-failure, log to /var/log/decnet/decnet.updater.log,
certs from /etc/decnet/updater, install tree at /opt/decnet), bundles
it alongside agent/forwarder/engine units, and the installer now
`systemctl enable --now`s it when --with-updater is set.
Wi-Fi APs bind one MAC per associated station, so VirtualBox/VMware
guests bridged over Wi-Fi rotate the VM's DHCP lease when Docker's
macvlan starts emitting container-MAC frames through the vNIC. Adds a
`use_ipvlan` toggle on the Agent Enrollment tab (mirrors the updater
daemon checkbox): flips the flag on SwarmHost, bakes `ipvlan=true` into
the agent's decnet.ini, and `_worker_config` forces ipvlan=True on the
per-host shard at dispatch. Safe no-op on wired/bare-metal agents.
Rename log-file-path -> log-directory (maps to DECNET_LOG_DIRECTORY). Bundle
now ships three systemd units rendered with agent_name/master_host and installs
them into /etc/systemd/system/. Bootstrap replaces direct 'decnet X --daemon'
calls with systemctl enable --now. Each unit pins DECNET_SYSTEM_LOGS so agent,
forwarder, and deckies logs land at decnet.{agent,forwarder}.log and decnet.log
under /var/log/decnet.
