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.

🎯 Guiding Principles

Zero Downtime Deployments: Utilize the Blue/Green architecture outlined in 04-04 wherever possible.
Infrastructure as Code: No manual unscripted changes. Modify the docker-compose.yml specs and .env.production templates directly.
Automated Backups: Backups must be validated automatically using the ASUSTOR pulling mechanism in 04-02.
Actionable Alerts: No noisy monitoring. Prometheus alerts in 04-03 should route to Slack/PagerDuty only when action is required.
