Overview

If you need to deploy multiple Nginx Ingress Controllers, that is, you want to use different traffic entries with different Ingress rules:

You can deploy multiple Nginx Ingress Controllers for the cluster and specify different ingressClassName for different Ingresses.
This document describes the configuration methods for installing multiple Nginx Ingress Controllers.

Configuration Method

To install multiple Nginx Ingress Controllers, you need to specify ingressClassName in values.yaml (ensure there are no conflicts):
controller:
  ingressClassName: prod
  ingressClassResource:
    name: prod
    controllerValue: k8s.io/ingress-prod
Note:
Three fields need to be changed simultaneously.
Additionally, the release names for multiple instances must be different from those of installed ones. Even if the namespaces are different, the release names cannot be the same (to avoid ClusterRole conflicts). The sample code is as follows:
helm upgrade --install prod ingress-nginx/ingress-nginx \\
  --namespace ingress-nginx --create-namespace \\
  -f values.yaml
When creating Ingress resources, you also need to specify the corresponding ingressClassName:
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: nginx
spec:
  ingressClassName: prod
  rules:
    - http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: nginx
                port:
                  number: 80
