ConfigMap 생성
1. 01.configmap/configmap.sh
bxcm-install-gen.sh Shell에 의해 생성되어진 설치 yaml 파일의 변경 사항이 없는 경우에는 configmap.sh 을 이용하여 한번에 생성할 수 있다.
다음은 configmap.sh Shell을 실행한 예이다.
01.configmap$ sh configmap.sh

configmap/job-execution-template created
>> kubectl apply -f webadmin-configmap.yaml
configmap/bxframework-webadmin created

####################################################################################2. ConfigMap 개별 생성
ConfigMap에 정의되어 있는 프레임워크 설정을 프로젝트에서 구축되는 환경에 따라 추가, 변경 등이 있을 수 있다. 이럴 경우에는 ConfigMap 생성 yaml 파일을 프로젝트 환경에 맞에 수정한 후 kubectl Command를 이용하여 적용하면 된다.

다음은 각 ConfigMap에 대한 자세한 내용과 적용 방법에 대해서 기술하였다.
