Azure-AKS 생성하기

Azure에서 AKS 구축하기!!

I CAN DO IT :)

 

나의 참고 사이트 : https://learn.microsoft.com/ko-kr/azure/aks/learn/quick-kubernetes-deploy-portal?tabs=azure-cli

 

 

클러스터 만들기

 

 

리소스그룹 이름: RG-jytestsvc-001

K8S 클러스터 이름: k8s-jytest-001

이건.. 기본 노드 풀인데.. 이걸 수정해 주어야 하는건지를 모르겠다 ㅠㅠ

왜냐면, 삭제하고 새롭게 nodepool을 생성해주었더니 위와 같이 만들 수 없다고 나옴..

어쨋든 노트 풀 추가해주기!

노드 풀 이름: jytestpool

노드 크기도 D2v_v3로 해주었다.

 

모니터링 모두 없애기 해주었고 -> 만들기!

애플리케이션 테스트

kubectl get pods

모든 Pod가 Running인지 확인합니다.

 

kubectl get service store-front --watch

store-front 애플리케이션의 공용 IP 주소를 확인합니다. 

--watch 인수와 함께 kubectl get service 명령을 사용하여 진행 상황을 모니터링합니다.

 

 

 

20.247.160.188으로 접속하면! 

아래와 같이 테스트 이미지 페이지가 보여진다 :) 굿

 

 

이대로 따라하니 성공했다!!
