kubernetes minikube install

minikube

쿠버네티스를 로컬에서 실행하려면 master node 와 slive node를 구성해야 하는데 이는 많은 비용이 들기때문에 간단하게 로컬에서 구성해 볼수있는 시스템이 있다. 이것이 바로 minikube 이다.

현업에서 실제 운영할때는 minikube를 구성하여 사용하지 않고 kubeadm 을 이용하여 구축한다고 한다. minikube는 학습용으로 쿠버네티스를 쉽게 배우고 개발 할 수 있도록 하는데 중점을 둔 로컬 쿠버네티스이다.

이전에 docker 설치와 kubernetes 를 활성화 해두어 중간에 kubectl 설치시 에러가 난게 보인다. 이부분은 무시해도 된다.
