ㅁ 들어가며

 ㅇ CKA 자격증을 준비하면서 다중노드환경이 필요하였다.

 ㅇ Taron님의 블러그를 참조하여 만들었습니다.

 ㅇ 기본적으로 kubectl과 docker 설치는 Taron님의 블러그를 참조하세요.

 

ㅁ minikube install

brew install minikube

 

ㅁ minikube start

minikube start --driver docker

 

ㅁ Ingress 설치

$ minikube addons enable ingress

 

ㅁ 클러스터 노드 확인

minikube node list

 

ㅁ Worker 노드 생성

minikube node add --worker

 

ㅁ Role 추가 및 확인

$ kubectl label node minikube-m02 node-role.kubernetes.io/worker=worker
node/minikube-m02 labeled
$ kubectl get nodes -o wide
