Continuous Integration and Deployment Engineering Journal

🔍 Overview

Phase ini mencatat seluruh perjalanan rekayasa otomasi Continuous Integration (CI) dan Continuous Deployment (CD) berbasis Jenkins untuk seluruh komponen platform Tomcat Monitoring (tomcat-monitoring, tomcat-diagnostic-service, tomcat-diagnostic-event-collector).

Fokus utama fase ini adalah membangun pipeline pengiriman kontainer berstandar Enterprise Production-Ready yang mengedepankan keamanan tanpa kebocoran rahasia (Zero Secret Leakage), pembuktian mutu bertingkat (Multi-Stage Quality Gates), kemasan OCI yang tidak berubah (Immutable OCI Artifacts), serta mekanisme Zero-Downtime Deployment dengan Automated Rollback pada runtime Rootless Podman.

🎯 Objective

Platform Tomcat Monitoring membagi otomasi CI/CD ke dalam 4 Lapisan Arsitektur (Architectural Layers) yang masing-masing dikelola oleh alur Jenkins Pipeline as Code tersendiri sesuai batas tanggung jawabnya (Separation of Concerns):

🎓 Lessons Learned

  1. Pemisahan Fase Dokumentasi CI/CD: Memisahkan dokumentasi CI/CD ke dalam workstream khusus (Continuous Integration and Deployment) memberikan kejelasan batas tanggung jawab antara integrasi fungsional monitoring dengan otomatisasi siklus hidup pengiriman software.
  2. Kesiapan Produksi Ditentukan Sejak Perancangan Awal: Menambahkan parameterisasi registry, penegakan isolasi secret, dan mekanisme rollback otomatis sejak fase desain mencegah timbulnya technical debt saat kode dipindahkan dari lab ke server produksi enterprise.
  3. Portabilitas Multi-Engine Menghilangkan Keterikatan Infrastruktur: Penggunaan helper adaptif berbasis shell POSIX memungkinkan eksekusi skrip otomasi yang seragam di lingkungan Red Hat (Podman) maupun Debian/Ubuntu (Docker) tanpa konfigurasi manual tambahan.
  4. Container Engine Socket API Melampaui Batasan OS: Menggunakan antarmuka soket/API resmi kontainer engine membebaskan platform dari ketergantungan pada shell host OS (Bash vs PowerShell) dan menghasilkan interaksi streaming event yang jauh lebih tangguh dan terstruktur.
  5. Manajemen Swap & Volume Izin Kunci Ketahanan Cloud Murah: Pada node cloud terbatas seperti AWS Free Tier (1GB RAM), konfigurasi swap 2GB dan otomatisasi perbaikan izin UID Docker (chown 1000:1000) pada named volume menjamin seluruh kontainer dan daemon beroperasi tanpa risiko OOM killer atau permission error.
