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.
The bootstrap was installing into /opt/decnet/.venv with an editable
`pip install -e .`, and /usr/local/bin/decnet pointed there. The updater
writes releases to /opt/decnet/releases/active/ with a shared venv at
/opt/decnet/venv — a parallel tree nothing on the box actually runs.
Result: updates appeared to succeed (release dir rotated, SHA changed)
but systemd kept executing the untouched bootstrap code.
Changes:
- Bootstrap now installs directly into /opt/decnet/releases/active
with the shared venv at /opt/decnet/venv and /opt/decnet/current
symlinked. Same layout the updater rotates in and out of.
- /usr/local/bin/decnet -> /opt/decnet/venv/bin/decnet.
- run_update / run_update_self heal /usr/local/bin/decnet on every
push so already-enrolled hosts recover on the next update instead
of needing a re-enroll.
- run_update / run_update_self now log each phase (receive, extract,
pip install, rotate, restart, probe) so the updater log actually
shows what happened.
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.
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.
