An overview of Kubernetes Ingress resources and the controllers that fulfill them, covering terminology, creation, and prerequisites.

Explains how the rewrite-target annotation in the NGINX Ingress controller maps user-facing URL paths to backend services, preventing 404 errors. Includes examples of simple and regex-based rewrites.

A practical walkthrough of the Kubernetes Gateway API using the NGINX Gateway Controller, covering HTTP routing, TLS termination, traffic splitting, and multi-protocol support. The concepts are implementation-agnostic and apply across any Gateway API-compatible controller.

Kubernetes provides a built-in DNS service that assigns predictable names to Services and Pods within a cluster. By default, pods use cluster.local as their search base for internal DNS resolution, enabling communication through human-readable names rather than ephemeral IP addresses.

Network namespaces provide the foundation for container network isolation in Docker and Kubernetes. This guide covers listing, creating, and linking namespaces, bridging, NAT, and how Docker and Kubernetes build on these primitives.

A practical guide to installing and configuring the Ingress-Nginx Controller in Kubernetes, covering Helm and kubectl methods, cloud-provider annotations, and local testing workflows.
