# Infrastructure & Operations (OPS) Guide

**Project:** LCBP3-DMS
**Version:** 1.8.9 (Infrastructure Hardening)
**Last Updated:** 2026-04-18

## 📋 Overview

This directory (`04-Infrastructure-OPS/`) serves as the single source of truth for all infrastructure setups, networking rules, Docker Compose configurations, backups, and site reliability operations for the LCBP3-DMS project.

It consolidates what was previously split across multiple operations and specification folders into a cohesive set of manuals for DevOps, System Administrators, and On-Call Engineers.

> **🔒 v1.8.9 Infrastructure Hardening (Apr 2026):**
> Full Docker Compose security pass completed — 27 findings (C1–C6, H1–H7, M1–M9, L1–L5, S1–S4) addressed.
> All secrets externalized, container hardening applied, auth enforced on Mongo + Registry. See `04-00-docker-compose/SECURITY-MIGRATION-v1.8.6.md` for the full runbook.

### 🐳 Live Docker Compose Files (v1.8.9)

ทั้งหมดย้ายมาอยู่ใต้ [`04-00-docker-compose/`](./04-00-docker-compose/) แล้ว พร้อม hardening (secrets ผ่าน `env_file`, `read_only`, `cap_drop`, healthchecks, resource limits, auth บน Mongo + Registry):

| Stack | File | Path on NAS |
| ----- | ---- | ----------- |
| **App** (backend + frontend + clamav) | `QNAP/app/docker-compose-app.yml` | `/share/np-dms/app/` |
| **Database** (mariadb + pma) | `QNAP/mariadb/docker-compose-lcbp3-db.yml` | `/share/np-dms/mariadb/` |
| **Services** (redis + elasticsearch) | `QNAP/service/docker-compose.yml` | `/share/np-dms/services/` |
| **Reverse Proxy** (npm + landing) | `QNAP/npm/docker-compose.yml` | `/share/np-dms/npm/` |
| **Git** (gitea) | `QNAP/gitea/docker-compose.yml` | `/share/np-dms/git/` |
| **Automation** (n8n + tika + docker-socket-proxy) | `QNAP/n8n/docker-compose.yml` | `/share/np-dms/n8n/` |
| **Chat** (mongodb + rocketchat) | `QNAP/rocketchat/docker-compose.yml` | `/share/np-dms/rocketchat/` |
| **Monitoring Exporters** (node-exporter + cadvisor) | `QNAP/monitoring/docker-compose.yml` | `/share/np-dms/monitoring/` |
| **Registry** (registry + registry-ui, htpasswd auth) | `ASUSTOR/registry/docker-compose.yml` | `/volume1/np-dms/registry/` |
| **Gitea Runner** (act_runner) | `ASUSTOR/gitea-runner/docker-compose.yml` | `/volume1/np-dms/gitea-runner/` |
| **Monitoring Stack** (prometheus + grafana + loki + promtail + uptime-kuma) | `ASUSTOR/monitoring/docker-compose.yml` | `/volume1/np-dms/monitoring/` |

ไฟล์เสริม: [`x-base.yml`](./04-00-docker-compose/x-base.yml) (shared YAML anchors), [`.env.template`](./04-00-docker-compose/.env.template) (ตัวแบบ secrets), per-stack `.env.example` ในแต่ละ folder.

## 🎯 Guiding Principles

1. **Zero Downtime Deployments**: Utilize the Blue/Green architecture outlined in `04-04` wherever possible.
2. **Infrastructure as Code**: No manual unscripted changes. Modify the `docker-compose.yml` specs and `.env.production` templates directly.
3. **Automated Backups**: Backups must be validated automatically using the ASUSTOR pulling mechanism in `04-02`.
4. **Actionable Alerts**: No noisy monitoring. Prometheus alerts in `04-03` should route to Slack/PagerDuty only when action is required.
5. **🔒 Secret Hygiene (v1.8.9)**: No secrets in git — use `env_file: .env` (gitignored) per stack. Rotate any secret that appeared in history. Roadmap: Docker Swarm secrets → Infisical / Vault / SOPS (see `04-00-docker-compose/README.md` §S1).
6. **Container Hardening (ADR-016 + M4)**: All app containers must set `security_opt: [no-new-privileges:true]`, `cap_drop: [ALL]`, non-root `user:`, and `read_only: true` where compatible. Pin every image tag — no `:latest` in production.
