DevOps

DevOps isn't a job title - it's a ceasefire between devs who ship code and ops who keep the lights on. You got your backend running locally , congrats. Now figure out how to get it to production without waking up to a 3AM PagerDuty alert because your Node process OOM-killed itself on a $5 VPS. A backend dev who understands DevOps ships faster , breaks less , and sleeps more - that's the whole game

12 files covering Docker , CI/CD , Kubernetes , monitoring , secrets management , and scaling - the survival tools you need when your Express API needs to handle 10k concurrent users and the connection pool throws in the towel

what you'll find here

  • Containerization - Docker intro , Dockerfiles , Docker Compose , multi-service setups
  • Container Security - Stop running everything as root , scan images for known vulns
  • CI/CD Pipelines - GitHub Actions that actually test and deploy properly
  • Environment & Secrets - .env management , secrets that stay secret , config per environment
  • Scaling - Horizontal scaling , database connection pooling , caching layers
  • Monitoring - Structured logging , Prometheus metrics , health checks , dashboards
  • Kubernetes - K8s fundamentals for when Docker Compose isn't enough
