The Upgrade of Kubernetes Ingress Nginx

The ingress-nginx container image I’ve been using was v0.25, and that’s more than 1 year old. The recent release is v0.44 but it’s a big leap from 25 to 44 and I’ve found some major differences between the 2 versions.

Version 0.25 implemented API version of networking.k8s.io/v1beta1 while version 0.44 has networking.k8s.io/v1. Here are samples for both versions:

# v1beta1
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: wordpress
  annotations:
    kubernetes.io/ingress.class: prod

  rules:

      http:
        paths:
          - path: /
            backend:
              serviceName: wordpress
              servicePort: 8080
# v1
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: wordpress
spec:
  ingressClassName: prod
  rules:
    - host: raynix.info
      http:
        paths:
          - path: /
            pathType: prefix
            backend:
              service:
                name: wordpress
                port: 
                  number: 8080
