만약 아래와 같은 에러가 나오면

  Exiting due to GUEST_MISSING_CONNTRACK: Sorry, Kubernetes 1.21.2 requires conntrack to be installed in root's path

minikube addons enable metric-server

혹시 아래와 같은 에러가 발생하면

Exiting due to MK_ADDON_ENABLE: run callbacks: metric-server is not a valid addon

오타가 난것이니 잘 보고 다시금 해보실..

addons list에서 나오는 항목을 복사해서 사용하는것이 좋을것~~으로 생각

minikube addons enable ingress

minikube addons enable metalb
