Kubernetes - NginxIngressController resources not creating - kubernetes

Question

We are using Nginx ingress operator version 0.2.0 and the controller version 1.11.1. Following steps are completed to deploy the CRD and operator.
https://github.com/nginxinc/nginx-ingress-operator/blob/release-0.2.0/docs/manual-installation.md
After that, we are deploying the controller using the following yaml:
apiVersion: k8s.nginx.org/v1alpha1
kind: NginxIngressController
metadata:
name: nginx-ingress-controller
namespace: ingress-nginx
spec:
type: deployment
image:
repository: nginx/nginx-ingress
tag: 1.11.1
pullPolicy: Always
serviceType: NodePort
nginxPlus: False
The manifest gets applied successfully but none of the required resources are getting created (deployment and service). Hence, the ingress is not getting the address.
kubectl get all -n ingress-nginx
No resources found in ingress-nginx namespace.
kubectl get ing
NAME CLASS HOSTS ADDRESS PORTS AGE
my-ingress <none> * 80 6h23m
kubeadm, kubelet & kubectl version 1.21.2.
Earlier we had deployed it on minikube and it was working fine.

Answer 1

I have reproduced the use case using Nginx ingress operator version 0.4.0 and the controller version 2.0.x by following the documentation and successfully created the Nginx Ingress Operator and NginxIngressController. Firstly, I didn't create the namespace ingress-nginx,While running the command
kubectl get all -n ingress-nginx. I was getting the error No resources found in ingress-nginx namespace.
After creating the required namespace by running the command kubectl create namespace ingress-nginx , I am able to get the resources(pod,service,deployment,replica set) successfully.
Can you try again by changing the nginx controller and operator versions to the latest one and also check the configurations correctly.
