Ingress Controller Setup

Overview

The ingress controller is responsible for:

• Managing external access to services
• Load balancing
• SSL/TLS termination
• Routing rules

Deployment Options

Helm Chart

Install with Helm

helm upgrade --install ingress-nginx ingress-nginx \
  --repo https://kubernetes.github.io/ingress-nginx \
  --namespace ingress-nginx \
  --create-namespace

Wait for the load balancer IP to be assigned:

kubectl get service -n ingress-nginx ingress-nginx-controller \
  --output jsonpath='{.status.loadBalancer.ingress[0].ip}'

Cloud Marketplace
