[ec2-user@ansible-server docker]$ ansible-playbook kube-deploy-svc.yml

-> 빨간 부분은 지울게 없어서 오류난 것
-> ignore를 안썼으면 저기서 멈춤

Git Bash(코드 수정)

$ rm -rf hello_world/
$ git clone https://github.com/seo369/hello-world.git
$ cd hello_world/
$ cd webapp/src/main/webapp/
$ vi index.jsp -> 내용 변경
$ git add .
$ git commit -, "test1"
$ git push origin master

-> 빌드유발 해놔서 자동 빌드

-> 변경내용 잘 나옴

delete

$ kubectl delete all -all
$ eksctl delete cluster EKS-CLUSTER --region ap-northeast-2
