I just apply the yaml file to install ingress-nginx controller in my private VM.

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.1/deploy/static/provider/baremetal/deploy.yaml

got following result, but it looks like ingress pod is working and i can access it(via node ip:port).

root@master01 ~# kubectl get pod -n ingress-nginx

NAME READY STATUS RESTARTS AGE ingress-nginx-admission-create-t7lfp 0/1 Completed 0 18s ingress-nginx-admission-patch-pghtm 0/1 CrashLoopBackOff 1 (15s ago) 18s ingress-nginx-controller-54cf4b5cfb-cj2vv 0/1 Running 0 18s root@master01 ~# kubectl get pod -n ingress-nginx -o wide

I just want to know why "ingress-nginx-admission-patch-pghtm" (patch job) always failed and any impact?

Following is logs for the pod log and pod descriptions

1. patch job pod log

root@master01 ~# kubectl logs ingress-nginx-admission-patch-pghtm -n ingress-nginx

**{"level":"info","msg":"patching webhook configurations 'ingress-nginx-admission' mutating=false, validating=true, failurePolicy=Fail","source":"k8s/k8s.go:38","time":"2022-02-14T11:19:40Z"}**

**{"err":"the server could not find the requested resource","level":"fatal","msg":"failed getting validating webhook","source":"k8s/k8s.go:47","time":"2022-02-14T11:19:40Z"}**

2. patch job pod description
