From Localhost to the Stars: My Kubernetes Odyssey (aka How I Stopped Worrying and Learned to Love the Cluster)

Short summary

The author contrasts docker-compose YAML with equivalent Kubernetes manifests for a Flask API + Postgres setup.

• •Docker Compose fails when moving from local to production; Kubernetes abstracts infrastructure details
• •Kubernetes controllers constantly reconcile actual state against your declared desired state
• •Practical walkthrough: converting a docker-compose setup to Kubernetes Deployments, Services, and PersistentVolumeClaims
