Container Orchestration Lessons: From Docker Compose to Kubernetes

Docker Compose got us from zero to production fast. But as we scaled past a handful of services, we needed proper orchestration.

Why We Moved

  • Auto-scaling based on CPU and memory thresholds
  • Self-healing — Failed containers restart automatically
  • Rolling deployments with automatic rollback
  • Service discovery without hardcoded URLs
  • Resource limits to prevent noisy neighbours

What Surprised Us

Kubernetes complexity is real. We spent a month getting observability right. But the operational wins — auto-scaling, self-healing, declarative config — made it worth it.
