🎯 Objective¶
Menetapkan recommendation dan Decision Handoff untuk restart policy, host-boot orchestration, ownership, startup dependency, serta verification boundary persistent lab monitoring tanpa mengubah source runtime atau container state.
🌍 Background¶
TN-035 menyelesaikan persistent Prometheus–Alertmanager–Mailpit delivery dan
menyisakan restart policy serta host-boot orchestration sebagai deferred
operability decision. Current-state Infrastructure masih mencatat owner
Runtime service continuity sebagai not determined.
Project owner menyetujui TN-036 sebagai documentation-only decision assessment pada 2026-08-30 dan menanyakan apakah TN ini menjadi Technical Note terakhir dalam phase Monitoring Integration and Runtime Deployment. Status tersebut tidak dapat diasumsikan hanya dari nomor TN: phase closure memerlukan keputusan eksplisit mengenai continuity serta disposition pekerjaan phase yang masih planned atau deferred.
📚 Scope¶
Aktivitas yang disetujui mencakup:
- read-only review terhadap Engineering Journal, current-state documentation, repository boundary, dan lifecycle interface runtime terkait;
- assessment alternatif manual continuity, container restart policy, dan rootless systemd/Quadlet orchestration;
- penetapan recommendation, decision questions, ownership boundary, dan verification criteria; serta
- pembuatan TN-036 dan pembaruan phase navigation.
Aktivitas ini tidak mencakup source atau configuration change pada
tomcat-monitoring maupun runtime repository, Podman inspection, container
mutation, host service change, host reboot, implementation, runtime test,
cleanup, ADR acceptance, commit, atau push.
📥 Inputs¶
| Input | State | Relevance |
|---|---|---|
TN-035 Next Steps |
Verified | Restart policy dan host-boot orchestration menjadi deferred operability decision. |
| Infrastructure ownership | Verified | Runtime service continuity belum memiliki owner atau mechanism yang diterima. |
| Runtime repository contracts | Observed | run.sh membuat container secara langsung dan tidak menetapkan restart atau host-boot contract. |
| Integration repository contract | Verified | Deployment orchestration dimiliki tomcat-monitoring; generic runtime repository tidak boleh mengambil alih automation project. |
| Project owner direction | Accepted | TN-036 dijalankan sebagai penutup phase; capability lanjutan dibahas pada phase baru ketika aktivitasnya dimulai. |
🔍 Findings¶
- Source
tomcat-monitoringsaat ini menyediakan configuration initializer, validator, dan integration fixtures, tetapi belum menyediakan deklarasi service host atau deployment orchestration untuk memulihkan topology setelah reboot. - Runtime
run.shTomcat/JMX Exporter, Telegraf, Prometheus, dan Alertmanager menjalankanpodman run --detachtanpa restart policy. Source inspection tersebut tidak membuktikan current container settings atau host service state karena runtime inspection berada di luar approved scope. - Menambahkan policy pada generic runtime repository akan melanggar ownership boundary: availability expectation, startup ordering, environment identity, dan deployment verification merupakan tanggung jawab integration orchestration.
--restartpada container dapat menjadi bagian dari process-recovery policy, tetapi tidak cukup sebagai host-boot contract tanpa mechanism host yang menjalankan kembali rootless container dan menetapkan ordering.- Rootless systemd/Quadlet merupakan kandidat yang paling lengkap bila target membutuhkan automatic recovery setelah process failure dan host reboot. Kelayakannya belum diverifikasi terhadap versi Podman/systemd, user lingering, lokasi unit, startup ordering, dan exact lab runtime.
- Ansible dan CI/CD tetap planned. Keduanya dapat menyediakan provisioning dan deployment yang reproducible, tetapi tidak otomatis menjadi boot-time service owner tanpa keputusan tambahan.
- Dashboard, CI/CD/Ansible, external delivery, container-status metrics, production deployment, dan end-to-end verification bukan objective yang harus diselesaikan di phase ini. Project owner menerima pemisahan pekerjaan tersebut ke phase baru ketika aktivitasnya benar-benar dimulai.
🔀 Alternatives¶
| Alternative | State | Capability | Trade-off |
|---|---|---|---|
| Manual recovery; continuity tetap deferred | Selected | Mempertahankan persistent lab sebagai environment yang dijalankan operator sesuai kebutuhan. | Tidak menjamin recovery otomatis setelah process failure atau host reboot. |
| Integration-owned container restart policy | Assessed | Dapat menangani sebagian process-exit recovery dengan policy yang disetujui. | Host-boot activation, dependency ordering, dan operator visibility tetap memerlukan contract terpisah. |
Rootless systemd/Quadlet di tomcat-monitoring |
Deferred | Dapat menyatakan container, network, volume, dependency, restart, dan boot lifecycle pada owner integration. | Ditinjau kembali hanya jika automatic continuity menjadi kebutuhan yang disetujui. |
| Ansible atau CI/CD sebagai boot-time owner | Rejected for boot lifecycle; retained for provisioning | Cocok untuk reproducible provisioning dan controlled deployment. | Pipeline atau playbook tidak seharusnya diasumsikan berjalan otomatis pada setiap host boot. |
⚠️ Risks¶
| Risk | State | Mitigation or Closure Condition |
|---|---|---|
| Restart loop menutupi configuration atau dependency failure | Deferred | Tidak ada restart automation pada current contract; review kembali sebelum future implementation. |
| Startup order tersedia tetapi readiness dependency belum terpenuhi | Deferred | Definisikan dependency dan readiness criteria jika automatic continuity dibuka kembali. |
| Rootless service tidak aktif saat host boot | Accepted | Current lab bersifat operator-managed dan tidak mengklaim automatic host-boot recovery. |
| Automation mereferensikan certificate atau secret secara tidak aman | Open | Gunakan existing non-Git material dan reference contract; jangan menyalin sensitive material ke unit atau Git. |
| Phase ditutup sementara outstanding work tidak memiliki tujuan penerus | Closed | Capability lanjutan dipisahkan ke phase baru ketika pekerjaan benar-benar dimulai. |
❓ Open Questions¶
| Question | State | Owner | Closure Condition | Blocked Activity |
|---|---|---|---|---|
| Apakah persistent lab harus pulih otomatis setelah container process failure dan host reboot? | Answered — operator-managed on 2026-08-30 | Project owner | Manual start dan recovery diterima sebagai current availability boundary. | Tidak ada; automatic continuity ditunda. |
| Siapa owner host-level rootless service lifecycle? | Deferred | Project owner atau infrastructure owner | Owner ditetapkan jika automatic continuity dibuka kembali. | Future continuity automation only. |
| Apakah rootless systemd/Quadlet diterima sebagai target mechanism? | Deferred | Project owner | Alternative dinilai kembali jika automatic continuity dibutuhkan. | Future continuity automation only. |
| Apakah TN-036 menjadi TN terakhir phase ini? | Answered — Yes on 2026-08-30 | Project owner | Capability lanjutan dipisahkan ke phase baru ketika aktivitasnya dimulai. | Tidak ada; phase closure dapat diselesaikan. |
💡 Recommendation¶
Pertahankan persistent lab sebagai operator-managed environment. Jangan menambahkan restart/boot behavior ke generic runtime repository dan jangan membuat implementation TN untuk continuity sebelum terdapat kebutuhan baru serta authorization terpisah.
Dashboard, container-status metrics, CI/CD/Ansible, external delivery, production deployment, dan end-to-end verification dicatat sebagai pekerjaan future. Phase baru dibuat hanya ketika salah satu aktivitas tersebut dimulai.
⚖️ Decision Handoff¶
Project owner menetapkan persistent lab sebagai operator-managed environment pada 2026-08-30. Restart policy dan host-boot automation ditunda; rootless systemd/Quadlet tetap menjadi alternatif future dan bukan accepted target implementation.
Project owner juga menetapkan TN-036 sebagai Technical Note terakhir phase Monitoring Integration and Runtime Deployment. Pekerjaan lanjutan dipisahkan ke phase baru ketika benar-benar dimulai. Keputusan ini tidak membatalkan pekerjaan future dan tidak mengotorisasi implementasinya.

🧾 Outcome¶
Assessment telah mengidentifikasi ownership boundary, empat alternatif,
recommendation bersyarat, risiko, dan decision questions. Tidak ada runtime
state yang diperiksa atau diubah, sehingga current container health dan
host-boot behavior tetap Not verified.
Project owner menerima operator-managed lab sebagai current availability boundary dan menutup phase pada TN-036. Tidak ada source, runtime, container, host-service, atau secret change. Runtime health dan host-boot behavior tidak diperiksa ulang dalam aktivitas documentation-only ini.
Documentation review lulus: changed tracked files dan TN baru tidak memiliki
whitespace error, TN-036 terdaftar pada phase index serta .pages, seluruh
relative documentation targets tersedia, dan heading structure telah direview.
Phase index berstatus Completed, current-state Infrastructure mencatat manual
start/recovery, dan stale In Progress decision text tidak ditemukan pada
TN-036 di luar command history.
MkDocs render berstatus Not verified karena executable tidak tersedia;
dependency tidak dipasang.
⏭️ Next Steps¶
Mulai phase baru hanya ketika dashboard, monitoring status container, CI/CD/Ansible, external delivery, production deployment, end-to-end verification, atau automatic continuity benar-benar dikerjakan dan memiliki scope serta authorization sendiri.
