배치작업의 시작
1. Kubernetes 환경일 경우 - yaml을 이용하여 배치작업 실행
|
Kubernetes에서의 yaml 파일을 이용한 Job 실행은 고객사의 프로젝트 환경에 따라 실행 할 수 있는 yaml을 서버에서 생성하여 관리할 필요가 있다. |
다음은 yaml 파일의 실행 예제이다.

# 배치 - Kubernetes Job 실행
$ kubectl apply -f batch-sample-job.yaml

# 배치 - Kubernetes Job 실행 결과 확인
$ kubectl get po | grep sample-init
