Deploy Staging / build (push) Failing after 1h1m21s
fix: auto-healer v5 — fix blocking bug, complete SRE flow verified
- Fixed blocking  command in incident reporting (added timeout 5s + --until now)
  Was causing the entire agent script to hang forever after saving each incident
- Full SRE flow now works end-to-end:
  1. Detect fault → 2. Fetch logs → 3. Analyze against knowledge base
  4. Save incident with full context (logs, inspect, events, resources)
  5. Execute restore protocol (rollback to :rollback image)
  6. Verify service restored
- 3 incidents successfully captured and logged with diagnostics
- All containers healthy, auto-healer monitoring every 30s

Error Knowledge Base

Log Pattern Root Cause Action
"Cannot find module" Missing dependency Rollback
"unexpected token" / "SyntaxError" JS parse error (bad deploy) Rollback
"heap out of memory" / "FATAL ERROR" OOM / memory leak Rollback
"ReferenceError" / "TypeError" Code bug Rollback
"PrismaClientInitializationError" DB connection issue Restart container
"ECONNREFUSED" / "ENOTFOUND" Downstream unreachable Restart container
"rate limit" / "429" Rate limiter Hotfix (auto-cleanup)
"jwt expired" / "invalid token" Config issue Check config → Rollback
"500" / "unhandled rejection" Unhandled exception Rollback
Container exit 137 / OOMKilled SIGKILL / OOM Rollback (if repeated)
Gateway 502 nginx down Reload gateway

Restore Protocol Steps

# 1. Save incident
cat > /var/log/falah/incidents/incident_$(date +%Y%m%d_%H%M%S).log << 'EOF'
... full diagnostics ...
EOF

# 2. Rollback
docker stop falah-mobile-staging
docker rm -f falah-mobile-staging  
docker run -d --name falah-mobile-staging \
  --restart unless-stopped \
  -p 4014:3000 \
  -v /var/services/homes/admin/falah-mobile/data:/app/data \
  --network falah-umbrel_falah-system \
  falah-mobile:rollback

# 3. Verify
curl -f http://localhost:4014/mobile/api/health

# 4. Report
echo "Incident: $id — rolled back to :rollback"

Hotfix Actions (no rollback needed)

  • Rate limit: Restart container (code auto-cleans every 5 min)
  • DB connection: Restart container (reconnect)
  • Gateway: nginx -s reload

Escalation

If 3+ restarts/hour or rollback fails:

  1. Log full incident with all diagnostics
  2. Do NOT restart again (leave for manual debug)
  3. Alert via available channels
