LanguageProject Introduction
Summary
This project provides a robust, high-performance Ingress controller implementation for Kubernetes, leveraging the power and reliability of NGINX. It serves as the standard way to route external HTTP/S traffic to services within a Kubernetes cluster.
Problem Solved
Kubernetes services are internal by default. Exposing them reliably and securely to external traffic, handling routing, load balancing, and SSL certificates across dynamic environments is complex. The NGINX Ingress Controller provides a standard, robust solution for this.
Core Features
Standard Ingress Features
Supports load balancing, SSL/TLS termination, and name-based virtual hosting out of the box.
Extensive Customization
Allows users to customize NGINX configuration using annotations and ConfigMaps.
Dynamic Configuration
Integrates with Kubernetes service discovery and updates configuration dynamically.
Tech Stack
Kubernetes
NGINX
Go
Lua
Use Cases
The Ingress NGINX Controller is essential for various scenarios requiring external access to applications running in Kubernetes.
Exposing Web Applications/APIs
Details
Expose web applications or APIs running as Kubernetes Services to the internet or an internal network via standard HTTP/S ports.
User Value
Provides a single entry point and handles routing, simplifying access management.
SSL/TLS Termination
Details
Terminate SSL/TLS connections at the cluster edge, offloading encryption/decryption from application pods.
User Value
Simplifies application code (no need for SSL handling in app) and centralizes certificate management.
Path or Host-Based Routing
Details
Route traffic to different backend services based on the request path or hostname (e.g., `/api` goes to service A, `/blog` goes to service B).
User Value
Enables running multiple services under a single domain or IP address.
