APEX Server Operations Skill (OPS-L3)

This skill encapsulates the operational competencies derived from the Jan-2026 Forensic Audit & SOP.

1. Zero-Downtime Deployment

Rolling Update Protocol

bash

# Scale up new containers first
docker compose up -d --no-deps --scale apex-api=2 apex-api

# Wait for health check (30 seconds)
sleep 30

# Verify new container is healthy
docker compose ps | grep apex-api

# Scale down to remove old container
docker compose up -d --no-deps --scale apex-api=1 apex-api

Verification

bash

# Continuous health check during deployment
while true; do curl -sf http://localhost:4000/health?skip_tenant_validation=1 && echo " OK" || echo " FAIL"; sleep 1; done

2. Forensic Log Analysis

Attack Pattern Detection

bash

# SQL Injection attempts
docker logs apex-api 2>&1 | grep -iE "union.*select|drop.*table|;.*--|or.*1.*=.*1"

# Cross-tenant violations
docker logs apex-api 2>&1 | grep -i "cross-tenant\|tenant context\|forbidden"

# Rate limit violations
docker logs apex-api 2>&1 | grep "Rate limit exceeded" | awk '{print $NF}' | sort | uniq -c | sort -rn | head 10

Automated Hourly Scan

Create /home/apex-v2-dev/apex-v2/scripts/security-scan.sh:

bash

#!/bin/bash
ERRORS=$(docker logs apex-api --since 1h 2>&1 | grep -cE "CRITICAL|SECURITY|AUDIT LOG FAILURE")
if [ "$ERRORS" -gt 0 ]; then
    echo "[ALERT] $(date): $ERRORS security events detected!"
fi

3. Secret Rotation Lifecycle

Sentry DSN Rotation

•Generate new key in Sentry Dashboard
•Update environment: sed -i 's|NEXT_PUBLIC_SENTRY_DSN=.*|NEXT_PUBLIC_SENTRY_DSN=NEW_DSN|g' .env
•Restart services: docker compose restart apex-api apex-storefront
•Invalidate old key in Sentry Dashboard

Database Password Rotation

bash

docker exec apex-postgres psql -U apex -c "ALTER USER apex WITH PASSWORD 'NEW_PASSWORD';"
sed -i 's|OLD_PASSWORD|NEW_PASSWORD|g' .env
docker compose restart apex-api

JWT Secret Rotation

⚠️ WARNING: This invalidates ALL active sessions!

bash

NEW_SECRET=$(openssl rand -base64 64 | tr -d '\n')
sed -i "s|JWT_SECRET=.*|JWT_SECRET=$NEW_SECRET|g" .env
docker compose restart apex-api

4. Precision Disaster Recovery

Full Database Backup

bash

docker exec apex-postgres pg_dump -U apex -d apex -Fc > ~/backups/$(date +%Y%m%d)/apex_full.dump

Tenant-Specific Backup

bash

TENANT_ID="demo-store"
docker exec apex-postgres pg_dump -U apex -d apex --schema="tenant_${TENANT_ID}" -Fc > ~/backups/tenant_${TENANT_ID}.dump

Tenant Restore (<5 minutes)

bash

docker exec apex-postgres psql -U apex -d apex -c "DROP SCHEMA IF EXISTS tenant_${TENANT_ID} CASCADE;"
docker exec -i apex-postgres pg_restore -U apex -d apex < ~/backups/tenant_${TENANT_ID}.dump

5. Emergency Kill Switch

bash

# Suspend malicious tenant immediately
curl -X PATCH http://localhost:4000/api/tenants/TENANT_ID/suspend
