Building Production Kubernetes Ingress Architectures

In Kubernetes clusters, an Ingress resource exposes HTTP and HTTPS routes from outside the cluster to services within the cluster. Proper Ingress configuration requires coordinating API versions, ingressClassName directives, cert-manager ClusterIssuer annotations for automated Let's Encrypt SSL certificates, CORS security headers, and rate-limiting rules. This generator produces validated, production-grade Ingress manifests ready to commit to GitOps repositories.

Frequently Asked Questions

What API version should modern Kubernetes Ingress use?

Modern Kubernetes clusters (version 1.19+) require networking.k8s.io/v1. Older versions like extensions/v1beta1 and networking.k8s.io/v1beta1 have been completely removed and deprecated in Kubernetes 1.22+.

How does cert-manager automatically issue SSL certificates for Ingress?

When you add the annotation 'cert-manager.io/cluster-issuer: <issuer-name>' to an Ingress and define a tls block, cert-manager detects the resource, creates an ACME HTTP-01 or DNS-01 challenge against Let's Encrypt, verifies domain ownership, and stores the resulting TLS keypair in the specified Kubernetes Secret.

What is the difference between Prefix and Exact pathType?

'Prefix' matches based on a URL path prefix split by '/'. For example, path: /api will match /api, /api/, and /api/v1. 'Exact' matches the URL path strictly letter-for-letter and will not match any child paths.

What is the role of ingressClassName in Kubernetes?

In networking.k8s.io/v1, the spec.ingressClassName field officially replaces the legacy 'kubernetes.io/ingress.class' annotation, directing the cluster to the specific Ingress Controller (such as nginx, traefik, or kong) that should manage the resource.
