Symptom

The NGINX Ingress Controller add-on is in the unknown state, and after this add-on is uninstalled, residual components still remain.

Involved Kubernetes resources include:

Namespace-level resources: secret, ConfigMap, Deployment, Service, Role, RoleBinding, lease, ServiceAccount, and job
Cluster-level resources: ClusterRole, ClusterRoleBinding, IngressClass, and ValidatingWebhookConfiguration

Solution

Use kubectl to access a cluster.

Search for related resources.

className="nginx"
namespace="kube-system"
className=`if [[ ${className} == "nginx" ]]; then echo ""; else echo "-${className}";fi`
kubectl get -n ${namespace} secret sh.helm.release.v1.cceaddon-nginx-ingress${className}.v1 cceaddon-nginx-ingress${className}-admission 
kubectl get -n ${namespace} cm cceaddon-nginx-ingress${className}-controller
kubectl get -n ${namespace} deploy cceaddon-nginx-ingress${className}-controller cceaddon-nginx-ingress${className}-default-backend
kubectl get -n ${namespace} svc cceaddon-nginx-ingress${className}-controller-admission cceaddon-nginx-ingress${className}-default-backend cceaddon-nginx-ingress${className}-controller
kubectl get -n ${namespace} role cceaddon-nginx-ingress${className}
kubectl get -n ${namespace} rolebinding cceaddon-nginx-ingress${className}
kubectl get -n ${namespace} lease ingress-controller-leader${className}
kubectl get -n ${namespace} serviceAccount cceaddon-nginx-ingress${className}
kubectl get clusterRole cceaddon-nginx-ingress${className}
kubectl get clusterRoleBinding cceaddon-nginx-ingress${className}
kubectl get ingressClass ${className}
kubectl get ValidatingWebhookConfiguration cceaddon-nginx-ingress${className}-admission

className specifies the name of a controller. namespace specifies the namespace where NGINX Ingress Controller was installed.

Manually delete the residual resources if the preceding resources are present.
