안녕하세요.
'수상한 김토끼' 입니다.
Oracle의 WebLogic Image Tool을 활용하여 WebLogic Docker Image 만들기 응용 2번째입니다.
이 블로그 글은 미들웨어 경험이 없으신 분들도 쉽게 따라 하실 수 있도록 쉽게 작성하는 것이 목표입니다.
설명을 보고 진행하시다가 궁금하신 내용은 댓글로 문의하시면 가능한 범위 내에서 알려 드리도록 하겠습니다.
1. 기존 WebLogic Domain Artifact 백업 생성
앞서 2장 응용 1번째에서 WebLogic Image Tool의 공식 홈페이지에 나와 있는 quick start와 같이 12c버전의 WebLogic이 아닌 14c버전을 docker image로 만들어 보았습니다.
이번에는 응용 2번째로 기존 WebLogic Domain Artifact를 백업하여 기존 Domain을 포함하는 14c 버전 docker image를 만들어 보도록 하겠습니다.
이번 장에서는 데모 웹 응용 프로그램 1개(데이터 소스도 포함될 수 있음)가 실행 중인 기존 WebLogic Domain Artifact를 백업하는 과정을 진행할 예정입니다.
최종적으로는 OCI(Oracle Cloud)의 OCIR(Container Registry)에 저장하여 OKE에 배포하는 것을 목표로 합니다.
WebLogic Domain Artifact 백업을 위해서는 'WebLogic Deploy Tooling'을 사용하며, WDT(WebLogic Deploy Tooling)는 일상적인 도메인 생성 및 애플리케이션 배포 작업을 위해 복잡한 WLST 스크립트를 작성할 필요가 없도록 도와주는 도구입니다.

:: WebLogic Deploy Tooling
WebLogic Deploy Tooling WebLogic Deploy Tooling (WDT) makes it easy to stand up WebLogic environments and perform domain lifecycle operations in a repeatable fashion based on a metadata model that can be treated as source and evolve as the project evolves.
oracle.github.io
우선 WDT를 다운로드하여 WebLogic이 설치된 서버에 업로드를 해 줍니다.
https://github.com/oracle/weblogic-deploy-tooling/releases

본 예제에서는 최신버전인 2.4.2를 사용하겠습니다.
다운로드한 파일을 서버에 업로드 후 압축을 풀어줍니다.

압축을 푼 디렉터리의 bin 디렉터리로 이동하여 discoverDomain.sh 명령을 실행하여 Artifact를 생성해 줍니다.
discoverDomain.sh는 다음과 같이 사용합니다.
./discoverDomain.sh -oracle_home /home/weblogic/weblogic14c/ -domain_home /home/weblogic/weblogic14c/domains/kami_domain/ -archive_file wls-k8s-domain.zip -model_file wls-k8s-domain.yaml| Key | Value | Note |
| oracle_home | /home/weblogic/weblogic14c/ | oracle 미들웨어가 설치된 경로 위치 |
| domain_home | /home/weblogic/weblogic14c/domains/kami_domain/ | 기존 WebLogic 도메인이 설치된 경로 위치 |
| archive_file | wls-k8s-domain.zip | 대상 도메인에 바이너리 및 기타 파일 리소스를 배포하기 위한 zip파일 아카이브 |
| model_file | wls-k8s-domain.yaml | 도메인 및 애플리케이션을 설명하는 yaml 파일 |
discoverDomain.sh 파일 실행결과는 다음과 같습니다.

WebLogic Domain Artifact 백업이 완료되었습니다.
2. Artifact yaml 파일 수정
Domain Artifact 백업이 완료되어 생성된 yaml 파일과 zip 파일의 일부 항목에 대한 수정이 필요합니다.
우선 생성된 yaml 파일(wls-k8s-domain.yaml)을 확인해 보면 다음과 같습니다.

이 yaml 파일에서 '--FIX ME--'의 값을 올바른 값으로 변경하여 저장하는 과정이 필요합니다.
| Key | Value | Note |
| AdminUserName | weblogic | WebLogic 관리자 사용자 |
| AdminPassword | weblogic! | WebLogic 관리자 암호 |
| NodeManagerPasswordEncrypted | 이 항목 제거 | 삭제 (불필요) |
| CredentialEncrypted | 이 항목 제거 | 삭제 (불필요) |
| PasswordEncrypted | weblogic! | 데이터 소스 사용자 비밀번호 |
본 예제에 사용된 데모 애플리케이션에서는 데이터 소스가 없어 'PasswordEncrypted'항목은 없습니다만 사용하시는 환경에 맞게 변경해 주시면 됩니다.
변경이 완료된 파일은 다음과 같습니다.

여기까지 WebLogic Domain Artifact 백업이 완료되었습니다.
이번장은 여기서 마무리하고 다음장에서 Artifact 기반 docker 이미지 생성과 관련된 내용을 알아보도록 하겠습니다.
