Pm2 Vps Release Guard

A production-grade release workflow for founders and small engineering teams running Node.js on a single Linux VPS with PM2 and Nginx, optionally behind Cloudflare. This skill makes an agent discover the real release contract before touching production, capture a safe baseline, protect .env/uploads/certificates/data, gate risky database migrations, restart only the intended PM2 process, verify from local upstream to public URL, and roll back from a known-good backup when a stop condition is met. Included: • A complete preflight → backup → deploy → verify → rollback workflow • A read-only Bash checker for PM2 status, restart stability, Nginx config, disk space, ports, and health endpoints • A detailed PM2/Nginx/Cloudflare runbook with rsync, cache, migration, and rollback patterns • Evidence-based release reporting that clearly states what was and was not verified Best for Node/Express/Next/Vite services on Ubuntu or Debian VPS hosts. It deliberately avoids Kubernetes and cloud-platform abstractions so single-server releases stay concrete, scoped, and recoverable.
