안녕하세요 쿠버네티스 네트워크 질문드립니다~!~!

Question

쿠버네티스 네트워크에서 인그레스실습에서 1. kubectl apply -k `pwd`/ingress-nginx/deploy/static/provider/baremetal/ 를 입력했더니 The connection to the server localhost:8080 was refused - did you specify the right host or port? 2. root@master:~# openssl req -x509 -nodes -days 365 -newkey rsa:2048 \ > -out ingress-tls.crt \ > -keyout ingress-tls.key \ > -subj "/CN=ingress-tls" --cert ingress-tls.crtGenerating a RSA private key .................................................+++++ ....+++++ writing new private key to 'ingress-tls.key' ----- root@master:~# root@master:~# kubectl create secret tls ingress-tls \ > --namespace default \ > --key ingress-tls.key \ > --cert ingress-tls.crt error: failed to create secret Post "http://localhost:8080/api/v1/namespaces/default/secrets?fieldManager=kubectl-create": dial tcp [::1]:8080: connect: connection refused 이렇게 뜨는데 어디를 바꾸면 될까요??
