Docker & Kubernetes

A practical guide to containerizing applications and running them reliably in Kubernetes. This skill covers the full lifecycle from writing a production-ready Dockerfile to deploying with Helm, configuring traffic with Ingress, and debugging cluster issues. The emphasis is on correctness and operability - containers that are small, secure, and observable; Kubernetes workloads that self-heal, scale, and fail gracefully. Designed for engineers who know the basics and need opinionated guidance on production patterns.
