-## ADR-008: Update Automation - Watchtower
+## ADR-008: Update Automation - Diun + Custom Scripts
 
 **Date**: 2026-06-08  
-**Status**: Accepted
+**Status**: Accepted (Updated 2026-06-09)
 
-**Decision**: Watchtower for Docker image updates
+**Decision**: Diun (Docker Image Update Notifier) for monitoring + custom bash scripts for orchestration
 
 **Rationale**:
-- Purpose-built for Docker environments
+- Diun monitors for updates and sends email notifications (built-in)
-- Simple to configure (runs as container)
+- Enables differentiated update policies per container
-- Automatic image updates on schedule
+- Custom scripts provide full control over update workflow
-- Minimal complexity
+- Supports pre-update backups and health checks
+- Allows manual approval for critical components (Gitea, PostgreSQL)
+- Auto-update for low-risk components (nginx, certbot)
+- Demonstrates production-level engineering (not just "update everything")
 
-**Scope**: Monitor and update Gitea, nginx, and other containers
+**Update Strategy**:
+- **Schedule**: Weekly checks during off-hours
+- **Nginx/Certbot**: Automatic updates after backup
+- **Gitea/PostgreSQL**: Email notification, manual approval required
+- **Backup**: Pre-update backup to S3 (database + Gitea data)
+- **Health Checks**: Post-update validation
+- **Rollback**: Automatic rollback on health check failure
+- **Notifications**: Email alerts on critical failures, logs for successful updates
+
+**Scope**: 
+- Diun container monitors all Docker images
+- `auto-update.sh` - automated update for nginx/certbot
+- `manual-update.sh` - operator-approved update for gitea/postgres
+- Health check and rollback logic
+
+**Alternative Considered**: Watchtower - rejected because it lacks per-container policies, pre-update backups, and proper notification support
+

+
+## ADR-012: CI/CD - Gitea Actions with Self-Hosted Runners
+
+**Date**: 2026-06-11  
+**Status**: Accepted
+
+**Decision**: Use Gitea Actions with self-hosted runners for CI/CD
+
+**Rationale**:
+- Native integration with Gitea (no external CI service)
+- Self-hosted runners provide full control and security
+- GitHub Actions-compatible workflow syntax (familiar, well-documented)
+- Enables automated testing before merging changes
+- Demonstrates production-grade CI/CD practices
+
+**Implementation**:
+- **Runners**: 2x act_runner v0.2.10 instances as systemd services
+- **Automation**: Ansible playbook (setup-runner.yml) for reproducible deployment
+- **Runner Registration**: Automated via Gitea API with token from AWS Secrets Manager
+- **Networking**: Host network mode for job containers to access Gitea
+- **Registration URL**: https://git.poll-streams.com (public URL for git clone operations)
+- **Workflow**: .gitea/workflows/test.yml runs integration tests on PRs
+- **Features**: Docker layer caching, artifact uploads, workflow_dispatch support
+
+**Technical Details**:
+- Each runner has dedicated config directory (/etc/act_runner-{1,2})
+- Configuration includes host networking to allow job containers to reach services
+- Runners registered with public URL to avoid localhost connection issues
+- Systemd manages runner lifecycle with automatic restart
+
+**Benefits**:
+- Automated quality gates before merging
+- Consistent test environment (matches CI exactly)
+- Fast feedback on code changes
+- Self-contained solution (no external dependencies)

+# Backup Strategy
+
+## Overview
+
+Implements the **3-2-1 rule**: 3 copies of data, on 2 different storage types, with 1 offsite.
+
+| Copy | Location | Type | Retention |
+|------|----------|------|-----------|
+| 1 | EC2 (EBS) | Block Storage | Live |
+| 2 | S3 Standard | Object Storage | 30 days |
+| 3 | S3 Glacier | Cold Storage | 90 days |
+
+## What is Backed Up
+
+1. **PostgreSQL Database** (`database-*.sql.gz`) - All application data, users, repos metadata
+2. **Gitea Data** (`gitea-data-*.tar.gz`) - Git repositories, LFS objects, attachments, SSH keys
+3. **Configuration** (`config-*.tar.gz`) - docker-compose.yml, nginx configs, .env, scripts
+
+## Backup Schedule
+
+| Type | Frequency | Time | Script |
+|------|-----------|------|--------|
+| Automated | Daily | 02:00 UTC | `/opt/gitea/scripts/backup.sh` |
+| Pre-Update | Before updates | Variable | Called by update scripts |
+| Manual | On-demand | N/A | Run backup.sh manually |
+
+**Location**: `s3://qvest-task-backups/backups/`
+
+## Retention & Lifecycle
+
+```
+Day 1-30:  S3 Standard (instant access)
+Day 31-90: S3 Glacier (retrieval: minutes to hours)
+Day 90+:   Automatically deleted
+```
+
+Managed by Terraform (`terraform/storage.tf`). S3 versioning enabled with 30-day noncurrent version expiration.
+
+## Restore Procedures
+
+### Quick Restore
+
+```bash
+# List available backups
+sudo /opt/gitea/scripts/restore.sh
+
+# Restore specific backup
+sudo /opt/gitea/scripts/restore.sh <timestamp>
+# Example: sudo /opt/gitea/scripts/restore.sh 20260611_164408
+```
+
+The script will:
+1. Prompt for confirmation
+2. Download backups from S3
+3. Stop services
+4. Restore database, data, and configuration
+5. Restart and verify services
+
+## Disaster Recovery Scenarios
+
+### Database Corruption
+**Solution**: Database-only restore
+
+### Repository Deletion
+**Solution**: Full restore (database + data must match)
+
+### Complete Instance Failure
+**Solution**: Rebuild infrastructure + restore  
+**Steps**:
+1. `terraform apply`
+2. `ansible-playbook site.yml`
+3. `restore.sh`
+4. Update DNS if needed
+
+## Security
+
+- **Encryption**: S3 server-side AES-256 encryption enabled
+- **Access**: EC2 IAM role with S3FullAccess (consider tightening to bucket-specific)
+- **Data Sensitivity**: Backups contain passwords, SSH keys, API tokens - restrict S3 bucket access
+
+⚠️ **Note**: `.env` file with secrets is included in config backups. Secure S3 bucket appropriately.

 ## Components
 
+### Docker Containers
 - **Nginx**: Reverse proxy handling SSL termination and routing to Gitea
-- **Gitea**: Git server application (main service)
+- **Gitea**: Git server application with Actions enabled (HTTP: 3000, SSH: 2222)
 - **PostgreSQL**: Database storing repositories metadata, users, issues
-- **Watchtower**: Monitors Docker Hub for image updates, automatically pulls and restarts containers
+- **DIUN**: Monitors Docker Hub for image updates, sends email notifications
+- **Certbot**: Handles Let's Encrypt SSL certificate renewal
+
+### Systemd Services
+- **act_runner-1**: First Gitea Actions runner for CI/CD workflows
+- **act_runner-2**: Second Gitea Actions runner for CI/CD workflows
 
 ## Container Communication
 
-- All containers in the same Docker network
+- All containers in the same Docker network (`gitea-network`)
 - Nginx proxies HTTPS requests to Gitea's internal port 3000
-- Gitea connects to PostgreSQL via container name
+- Gitea connects to PostgreSQL via container name (`postgres`)
-- Watchtower runs on schedule, checking for updates
+- DIUN monitors containers based on labels (`diun.enable=true`)
-- Let's Encrypt certbot renews certificates automatically (via nginx container or separate container)
+- Certbot shares volumes with nginx for certificate storage
+- Runners connect to Gitea via `http://localhost:3000`
 
 ## Data Persistence
 
 Docker volumes ensure data survives container restarts:
-- `gitea_data`: Git repositories and uploads
+- `gitea-data`: Git repositories and uploads
-- `postgres_data`: Database files
+- `gitea_postgres-data`: PostgreSQL database files
+- `certbot-etc`: Let's Encrypt certificates
+- `certbot-var`: Certbot working directory
+- `web-root`: ACME challenge files for SSL verification

 ## Traffic Flow
 
-1. User accesses `gitea.yourdomain.com`
+1. User accesses `git.poll-streams.com`
 2. Route 53 resolves to EC2 public IP
 3. Request hits EC2 (nginx handles SSL, proxies to Gitea)
 4. EC2 regularly backs up data to S3
+5. Ansible fetches credentials from Secrets Manager during deployment
+6. Gitea generates runner token via API, stored back in Secrets Manager

+```
+
+## Test Suite
+
+The `scripts/test-integration.sh` integration test suite validates:
+
+1. **Static validation** (2 tests):
+   - Script syntax and linting
+   - Required executables available
+
+2. **Docker-based tests** (12 tests):
+   - PostgreSQL backup and restore
+   - Health check functionality
+   - Archive validation (SQL and tar formats)
+   - Update simulation workflow
+   - Container cleanup and resource management
+
+All tests must pass for a PR to be mergeable.
+
+## Key Features
+
+### Zero-Configuration CI/CD
+- Runners automatically registered during initial deployment
+- No manual token management needed
+- Runner tokens stored securely in AWS Secrets Manager
+- Complete automation from infrastructure provision to working CI/CD
+
+### High Availability
+- 2 concurrent runners for parallel job execution
+- Automatic job distribution by Gitea
+- Systemd ensures runners restart on failure
+
+### Security
+- Runners use local Gitea instance (`http://localhost:3000`)
+- Admin credentials never exposed (CLI-based user creation)
+- IAM roles for least-privilege access to AWS resources
+- Runner tokens rotated on redeployment
+
+### Docker Optimization
+- Docker layer caching for faster builds
+- Image pre-pulling reduces test execution time
+- Shared Docker daemon for all tests
+
+## Deployment Commands
+
+```bash
+# Full deployment (includes runner setup)
+make full-deploy
+
+# Update only configuration (re-registers runners if needed)
+make configure
+
+# Run tests locally
+make test
+```

+
+## Update Policies
+
+### Automatic (Low Risk)
+- **nginx**: Reverse proxy with stateless configuration
+- Process: Detected → Backup → Update → Health Check → Success/Rollback
+- No operator intervention required
+
+### Manual (High Risk)
+- **gitea**: Git hosting application with user data
+- **postgres**: Database containing all repository data
+- Process: Detected → Email → Operator Reviews → Approval → Backup → Update → Health Check → Success/Rollback
+
+## Safety Mechanisms
+
+1. **Pre-Update Backup**: Database and Gitea data backed up to S3 before any changes
+2. **Health Checks**: Services validated after update (container running, postgres responding, gitea accessible, nginx config valid)
+3. **Automatic Rollback**: Failed health check triggers immediate rollback to previous image
+4. **Email Notifications**: Operator notified of:
+   - Available updates (manual containers)
+   - Update failures (all containers)
+   - Successful updates (manual containers only)
+
+## Certificate Renewal
+
+Runs separately at 3:30 AM on Sundays:
+- Certbot checks certificate expiration
+- Renews if within 30 days of expiry
+- Restarts nginx to load new certificate
+- Process is idempotent (safe to run weekly)
+
+## Monitoring
+
+**Diun Configuration**:
+- Schedule: `0 3 * * 0` (Sunday 3:00 AM)
+- Monitors: postgres, gitea, nginx, diun
+- Email: Via AWS SES SMTP
+- Labels: Containers marked with `diun.enable=true` and `update.policy=automatic|manual`
