如何删除 kubernetes 上的入口 controller？

Question

I have a Kubernetes cluster in which I have multiple ingress controllers. I have deleted the source file of one ingress controller. How can I delete the ingress controller that I don't want further??

Answer 1

first of all, you can follow below steps without manifest files:

1. get the namespace which your ingress controller installed in

   kubectl get ns 

for example: ingress-nginx

2- remove all resources in this namespace

kubectl delete all  --all -n ingress-nginx

if your ingress controller is not installed in a dedicated namespace so you will have to remove resources one by one.

kubectl delete ingress ingress-nginx
kubectl delete deployment ingress-nginx
kubectl delete service ingress-nginx
