User Scenarios & Testing (mandatory)
User Story 1 - Zero-Downtime Deployment (Priority: P1)
As a DevOps engineer, I need to deploy updates for all services (NAP-DMS applications, databases, monitoring, Gitea, n8n, RocketChat, and supporting services) without interrupting user access to any system components.
Why this priority: Critical for business continuity - system cannot afford downtime during regular maintenance windows.
Independent Test: Can be fully tested by deploying a test application version using blue-green containers and verifying traffic switches seamlessly without user session interruption.
Acceptance Scenarios:
- Given a running production environment, When I deploy a new version, Then users continue accessing the system without interruption
- Given a deployment failure, When the rollback is triggered, Then the system immediately switches back to the previous stable version
User Story 2 - Automated Backup & Recovery (Priority: P1)
As a system administrator, I need automated daily backups of all services data (NAP-DMS applications, databases, monitoring, Gitea, n8n, RocketChat, configurations, and supporting services) and the ability to restore the entire system within 4 hours of a catastrophic failure.
Why this priority: Essential for data protection and business continuity compliance with document management regulations.
Independent Test: Can be fully tested by running backup procedures and performing a full system restore in a test environment to verify all data is recoverable.
Acceptance Scenarios:
- Given the backup schedule is configured, When the daily backup runs, Then all databases, files, and configurations are successfully backed up
- Given a system failure occurs, When I initiate recovery, Then the entire system is restored to its last known good state within 4 hours
User Story 3 - Real-time Monitoring & Alerting (Priority: P1)
As an on-call engineer, I need to receive immediate alerts when any system components (NAP-DMS applications, databases, monitoring, Gitea, n8n, RocketChat, and supporting services) fail or performance degrades below acceptable thresholds.
Why this priority: Prevents minor issues from becoming major outages and ensures rapid response to system problems.
Independent Test: Can be fully tested by simulating various failure scenarios and verifying appropriate alerts are generated and delivered to the correct channels.
Acceptance Scenarios:
- Given monitoring is active, When a service becomes unresponsive, Then an alert is sent within 30 seconds
- Given system resources exceed 80% utilization, When the threshold is crossed, Then a performance alert is generated with actionable diagnostics
User Story 4 - Container Security Hardening (Priority: P2)
As a security administrator, I need all containers (NAP-DMS applications, databases, monitoring, Gitea, n8n, RocketChat, and supporting services) to run with minimal privileges and no exposed secrets to maintain compliance with security policies.
Why this priority: Prevents privilege escalation attacks and protects sensitive configuration data.
Independent Test: Can be fully tested by running security scans on all containers and verifying they meet hardening requirements.
Acceptance Scenarios:
- Given containers are deployed, When I run a security audit, Then all containers pass privilege escalation and secret exposure checks
- Given new containers are added, When they are deployed, Then they automatically inherit security hardening policies
User Story 5 - Infrastructure as Code Management (Priority: P2)
As a DevOps engineer, I need to manage all infrastructure configurations (NAP-DMS applications, databases, monitoring, Gitea, n8n, RocketChat, and supporting services) through version-controlled code files rather than manual server changes.
Why this priority: Ensures consistency across environments and enables reproducible infrastructure deployments.
Independent Test: Can be fully tested by deploying a complete environment from code and verifying it matches the production configuration.
Acceptance Scenarios:
- Given infrastructure code changes, When I apply the changes, Then the environment configuration matches exactly what's defined in the code
- Given a new environment is needed, When I deploy from code, Then the environment is created with all required services and configurations
Edge Cases
- What happens when network connectivity between QNAP and ASUSTOR fails during backup operations?
- How does system handle container registry authentication failures during deployment?
- What happens when Docker Compose files contain syntax errors during environment startup?
- How does system handle SSL certificate expiration for reverse proxy services?
- What happens when monitoring services become unavailable while system is running?
- How does system handle storage space exhaustion on production servers?
- What happens when multiple deployment processes are initiated simultaneously?
- How does system handle database connection pool exhaustion during high load?
- What happens when automated security updates conflict with custom container configurations?
- How does system handle partial backup failures where some services complete but others fail?
- How does system handle Email SMTP service failures for alert notifications?
- What happens when Let's Encrypt certificate renewal fails due to network issues?
