Phoenix Shield

PhoenixShield 🔥🛡️

"Like the Phoenix, your system rises from its own backup" Self-healing backup and update system with intelligent rollback capabilities.

Why PhoenixShield?

Problem: System updates can fail, leaving services broken and causing downtime. Solution: PhoenixShield provides a complete safety net with automatic rollback when things go wrong. Benefits: 🔄 Automatic Recovery - Self-heals when updates fail 🧪 Canary Testing - Test updates before production 📊 Health Monitoring - 24h post-update monitoring ⚡ Smart Rollback - Only revert changed components 🛡️ Zero-Downtime - Graceful degradation when possible

1. Initialize PhoenixShield

phoenix-shield init --project myapp --backup-dir /var/backups

2. Create Pre-Update Snapshot

phoenix-shield snapshot --name "pre-update-$(date +%Y%m%d)"

3. Safe Update with Auto-Recovery

phoenix-shield update \ --command "npm update" \ --health-check "curl -f http://localhost/health" \ --auto-rollback

4. Monitor Post-Update

phoenix-shield monitor --duration 24h --interval 5m

1. Pre-Flight Checks

Before any update, PhoenixShield verifies: phoenix-shield preflight Checks: ✅ Disk space available ✅ No critical processes running ✅ Backup storage accessible ✅ Network connectivity ✅ Service health baseline

2. Intelligent Backup

# Full system snapshot phoenix-shield backup --full # Incremental (only changed files) phoenix-shield backup --incremental # Config-only backup phoenix-shield backup --config Backup includes: Configuration files Database dumps System state Process list Network connections Health metrics baseline

3. Canary Deployment

Test updates on isolated environment first: phoenix-shield canary \ --command "apt upgrade" \ --test-duration 5m \ --test-command "systemctl status nginx"

4. Production Update

Execute update with safety net: phoenix-shield deploy \ --command "npm install -g openclaw@latest" \ --health-checks "openclaw --version" \ --health-checks "openclaw health" \ --rollback-on-failure

5. Post-Update Monitoring

Automatic monitoring stages: TimeframeChecks0-5 minCritical services running5-30 minAll services responding30-120 minIntegration tests2-24hStability monitoring phoenix-shield monitor --start

6. Smart Rollback

When update fails, PhoenixShield: Attempts soft recovery - Restart services Config rollback - Revert configuration Package rollback - Downgrade packages Full restore - Complete system restore Emergency mode - Minimal services, notify admin # Manual rollback phoenix-shield rollback --to-snapshot "pre-update-20260205" # Check what would be rolled back (dry run) phoenix-shield rollback --dry-run

Safe OpenClaw Update

#!/bin/bash # Update OpenClaw with PhoenixShield protection phoenix-shield preflight || exit 1 phoenix-shield snapshot --name "openclaw-$(date +%Y%m%d)" phoenix-shield deploy \ --command "npm install -g openclaw@latest && cd /usr/lib/node_modules/openclaw && npm update" \ --health-check "openclaw --version" \ --health-check "openclaw doctor" \ --rollback-on-failure phoenix-shield monitor --duration 2h

Ubuntu Server Update

phoenix-shield deploy \ --command "apt update && apt upgrade -y" \ --health-check "systemctl status nginx" \ --health-check "systemctl status mysql" \ --pre-hook "/root/notify-start.sh" \ --post-hook "/root/notify-complete.sh" \ --auto-rollback

Multi-Server Update

# Update multiple servers with PhoenixShield SERVERS="server1 server2 server3" for server in $SERVERS; do phoenix-shield deploy \ --target "$server" \ --command "apt upgrade -y" \ --batch-size 1 \ --rollback-on-failure done

Configuration

Create phoenix-shield.yaml: project: my-production-app backup: directory: /var/backups/phoenix retention: 10 # Keep last 10 backups compression: gzip health_checks: - command: "curl -f http://localhost/health" interval: 30s retries: 3 - command: "systemctl status nginx" interval: 60s monitoring: enabled: true duration: 24h intervals: critical: 1m # 0-5 min normal: 5m # 5-30 min extended: 30m # 30-120 min stability: 2h # 2-24h rollback: strategy: smart # smart, full, manual auto_rollback: true max_attempts: 3 notifications: on_start: true on_success: true on_failure: true on_rollback: true

Integration with CI/CD

• # GitHub Actions example
• name: Safe Deployment
• run: |
• phoenix-shield preflight
• phoenix-shield snapshot --name "deploy-$GITHUB_SHA"
• phoenix-shield deploy \
• --command "./deploy.sh" \
• --health-check "curl -f http://localhost/ready" \
• --auto-rollback

1. Always Use Preflight

# Bad phoenix-shield deploy --command "apt upgrade" # Good phoenix-shield preflight && \ phoenix-shield deploy --command "apt upgrade"

2. Test Rollback Before Production

phoenix-shield snapshot --name test phoenix-shield deploy --command "echo test" phoenix-shield rollback --dry-run # See what would happen

3. Monitor Critical Updates

phoenix-shield deploy --command "major-update.sh" phoenix-shield monitor --duration 48h # Extended monitoring

4. Maintain Backup Hygiene

# Regular cleanup phoenix-shield cleanup --keep-last 10 --older-than 30d # Verify backups phoenix-shield verify --all

"Preflight check failed"

Check disk space: df -h Verify backup location exists Ensure no critical processes running

"Rollback failed"

Check backup integrity: phoenix-shield verify Manual restore from: /var/backups/phoenix/ Contact admin for emergency recovery

"Health checks failing"

Extend monitoring: phoenix-shield monitor --duration 48h Check service logs: journalctl -u myservice Consider partial rollback: phoenix-shield rollback --config-only
