Deploy Applications Efficiently with Kubernetes nginx Ingress: Caching Media and CSS Example
In today’s digital world characterized by endless data, application efficiency is more imperative than ever, and Kubernetes nginx ingress provides an ideal solution for deploying applications with optimum speed and agility.
Understanding Kubernetes nginx Ingress
Before we dive into the hands-on instructions, let’s take a moment to understand Kubernetes and its ingress. In the simplest terms, Kubernetes is an open-source platform designed for automating deployments, scaling, and managing containerized applications. A pivotal concept within the Kubernetes ecosystem is “ingress”, which is an API object that governs external access to the services in a cluster, typically HTTP.
Herein, let’s focus on how to use Kubernetes nginx Ingress for deploying applications with caching media and CSS as an example.
Why Use nginx Ingress?
So, why would you want to use nginx ingress? Well, it gives your apps a significant speed advantage by enhancing the usage of server resources and reducing response times with HTTP cache.
Prerequisites
Ensure you have the following before starting:
1. A working Kubernetes cluster
2. Helm installed
3. An understanding of how to configure Ingress resources.
Don’t worry if you’re unfamiliar with these.
Here is an excellent resource for getting started: Kubernetes Ingress Documentation.
Installation Steps
Step One: Installing the Ingress Controller
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm install my-release ingress-nginx/ingress-nginx
Step Two: Configuring the HTTP Cache
As part of the next step, you’re going to explore caching options. But first, here’s a piece of tech humor to ease the complexities for you: Why don’t programmers like nature? It has too many bugs!
kind: ConfigMap
apiVersion: v1
metadata:
name: nginx-config
data:
proxy_cache_path: "/var/cache/nginx levels=1:2
keys_zone=my_cache:10m max_size=10g inactive=60m
use_temp_path=off"Step Three: Configuring Nginx Ingress
kind: Ingress
apiVersion: networking.k8s.io/v1beta1
metadata:
annotations:
nginx.ingress.kubernetes.io/enable-vts-status: "true"

}Final Thoughts
Kubernetes Nginx Ingress, configured with caching, is an efficient way to deploy applications that deal with media and CSS. As we end this tutorial, remember, every great developer once got stuck at “Hello, World!” If you’re finding Kubernetes Nginx Ingress complex, you’re on the right track. Keep practicing and exploring, and you’ll master it in no time.
