If ci-backup-template.service is killed mid-run (SIGTERM), the Python finally block that restarts act-runner.service is skipped. A subsequent backup then finds the runner already inactive, _stop_runner returns False, and the finally restart is gated off — leaving the runner down indefinitely (incident: 21 mag 2026, runner stayed off ~80 min). Add ExecStopPost=-/bin/systemctl start act-runner.service so systemd guarantees the runner is restarted regardless of how the unit exits (success, failure, signal). The `-` prefix preserves the unit's own exit status. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
systemd units — Local CI/CD System (Linux host)
Coppie *.service + *.timer che replicano i task periodici registrati su
Windows da scripts/Register-CIScheduledTasks.ps1. Pensate per essere
installate su un host Linux Mint / Ubuntu LTS, con il package
ci_orchestrator installato in /opt/ci/venv/.
Mapping Windows Task Scheduler → systemd timer
| Windows Task Scheduler | systemd unit | Cadenza | Comando |
|---|---|---|---|
CI-CleanupOrphans |
ci-cleanup-orphans.timer |
every 6h + at boot | python -m ci_orchestrator vm cleanup --max-age-hours 6 |
CI-RetentionPolicy |
ci-retention-policy.timer |
daily 03:00 + at boot | python -m ci_orchestrator retention run |
CI-DiskSpaceAlert |
ci-watch-disk-space.timer |
every 15 min | python -m ci_orchestrator monitor disk |
CI-RunnerHealth |
ci-watch-runner-health.timer |
every 15 min | python -m ci_orchestrator monitor runner |
| (nuovo) | ci-backup-template.timer |
weekly Sun 02:00 | python -m ci_orchestrator template backup --all-templates |

Nota:
ci-backup-template.servicegira comeroot(nonci-runner) perché chiamasystemctl stop/start act-runner.serviceprima e dopo il backup. Tutti gli altri service girano comeci-runner.
Installazione
# 1. Copia le unit in /etc/systemd/system/
sudo cp deploy/systemd/ci-*.service deploy/systemd/ci-*.timer /etc/systemd/system/
# 2. Reload systemd
sudo systemctl daemon-reload
# 3. Abilita + avvia tutti i timer
for t in ci-cleanup-orphans ci-retention-policy ci-watch-disk-space \
ci-watch-runner-health ci-backup-template; do
sudo systemctl enable --now "${t}.timer"
done
# 4. Verifica
systemctl list-timers --all 'ci-*'
Test e troubleshooting
# Trigger manuale di un singolo task (esegue il .service una volta)
sudo systemctl start ci-cleanup-orphans.service
# Log dell'ultima esecuzione
journalctl -u ci-cleanup-orphans.service -n 50 --no-pager
# Live tail di tutti i task CI
journalctl -u 'ci-*' -f
Rollback
for t in ci-cleanup-orphans ci-retention-policy ci-watch-disk-space \
ci-watch-runner-health ci-backup-template; do
sudo systemctl disable --now "${t}.timer"
sudo rm -f "/etc/systemd/system/${t}.service" "/etc/systemd/system/${t}.timer"
done
sudo systemctl daemon-reload
A questo punto il fallback è ri-attivare i task su Windows con
scripts/Register-CIScheduledTasks.ps1.
