Minikube 설치 및 예제

Minikube는 로컬 Kubernetes 클러스터를 설정하는 도구로, 개발자와 Kubernetes 사용자들이 쉽게 사용할 수 있도록 설계되었습니다. 

Mac PC에서 Lima환경(Linux)에서 Minikube를 설치하였습니다.

Hello Minikube

 

Minikube 설치

https://minikube.sigs.k8s.io/docs/start/?arch=%2Fmacos%2Fx86-64%2Fstable%2Fbinary+download

macOS를 사용해서 다음과 같이 선택하였습니다.

minikube start

 

 

설치를 완료하면 minikube start합니다.

다음 명령어로 kubectl 명령어를 사용할 수 있습니다.
minikube kubectl -- get po -A

alias를 등록해서 사용 가능합니다.
alias kubectl="minikube kubectl --"

minikube는 Kubernetes 대시보드를 번들로 제공합니다.

Applications 배포
Service
Create a sample deployment and expose it on port 8080:

• kubectl create deployment hello-minikube --image=kicbase/echo-server:1.0
• kubectl expose deployment hello-minikube --type=NodePort --port=8080

It may take a moment, but your deployment will soon show up when you run:

• kubectl get services hello-minikube

The easiest way to access this service is to let minikube launch a web browser for you:

• minikube service hello-minikube

Alternatively, use kubectl to forward the port:

• kubectl port-forward service/hello-minikube 7080:8080

Tada! Your application is now available at http://localhost:7080/.

Cluster 관리 명령어

Pause Kubernetes without impacting deployed applications:

• minikube pause

Unpause a paused instance:

• minikube unpause

Halt the cluster:

• minikube stop

Change the default memory limit (requires a restart):

• minikube config set memory 9001

Browse the catalog of easily installed Kubernetes services:

• minikube addons list

Create a second cluster running an older Kubernetes release:

• minikube start -p aged --kubernetes-version=v1.16.1

Delete all of the minikube clusters:

• minikube delete --all
