이 글은 2022.8.2에 기존 T-Story 블로그에 작성했던 글 입니다. (https://with-kami.tistory.com/1534844)
안녕하세요.
‘수상한 김토끼’ 입니다.
Oracle의 WebLogic Image Tool을 활용하여 WebLogic Docker Image 만들기 응용 1번째입니다.
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. 최신 버전의 WebLogic Docker Image 만들기
앞장에서 WebLogic Image Tool의 공식 홈페이지에 나와 있는 quick start와 같이 12c버전의 WebLogic을 docker image로 만들어 보았습니다만 예제에 나와 있지 않은 최신버전의 docker image 생성도 가능합니다.
이번에는 14c 버전을 docker image로 만들어 보도록 하겠습니다.
Docker image로 만들 WebLogic 14c 파일을 다운로드하여 줍니다.
https://www.oracle.com/middleware/technologies/weblogic-server-installers-downloads.html
우선 ‘Generic’을 선택하여 다운로드 받아 서버에 업로드해 줍니다.
[root@middleware-works-centos8 tmp]# ls fmw_14.1.1.0.0_wls.jar
서버에 파일 준비가 완료되면 이전과 같이 cache에 등록 후 create 과정을 수행하면 되는데 한 가지 차이점이 있습니다.
바로 create 시에 ‘–version’ 옵션을 주어야 하는 점인데요 정리하면 다음과 같습니다.
기존 Docker Image 생성방법: ./imagetool.sh create --tag wls:14.1.1.0.0 (에러발생)
변경 Docker Image 생성방법: ./imagetool.sh create --version=14.1.1.0.0 --tag wls:14.1.1.0.0 (정상동작)WebLogic 14c의 경우 JDK는 8 버전과 11 버전을 사용할 수 있으니 이 부분은 필요에 따라 맞춰 주시면 되며 JDK11을 사용하기 위해서는 ‘–jdkVersion’ 옵션을 추가해 주시면 됩니다. 정리하면 다음과 같습니다.
JDK 11 기반 Docker Image 생성방법: ./imagetool.sh create --version 14.1.1.0.0 --jdkVersion=11.0.9 --tag wls:14.1.1.0.0-jdk11저는 JDK옵션은 주지 않고 기존의 8 버전으로 생성해 보겠습니다.

기존에 생성되었던 12c 외에 14c버전 이미지도 정상적으로 생성된 것을 확인할 수 있습니다.
2. WebLogic Slim 버전 Docker Image 파일 생성
이번에는 Docker Image에 조금 더 적합한 WebLogic slim 버전 docker image를 생성해 보겠습니다.
WebLogic slim 버전은 Generic 또는 Fusion Middleware Infrastructure Installer보다 용량이 훨씬 작은 버전입니다.
예제나 클라이언트, Java DB 등이 필요 없는 대부분의 docker 운영환경에 적합한 버전으로 WebLogic 다운로드 페이지에서 slim항목을 선택하여 다운로드할 수 있습니다.
slim 버전을 다운로드하여 서버에 업로드해 줍니다.
[root@middleware-works-centos8 tmp]# ls fmw_14.1.1.0.0_wls_lite_slim_Disk1_1of1.zip
파일이 준비 되었으니 14c 버전과 동일하게 docker image를 생성해 보겠습니다.

정상적으로 WebLogic 14c 버전 slim docker image가 생성되었습니다.
Generic 버전과 약 300메가 정도 차이가 나는 것을 확인할 수 있으며, 수십 ~ 수백 대의 컨테이너를 운용하는 환경의 경우 더욱 효과가 클 것으로 보입니다.
이런 방법을 활용하면 WebLogic 뿐만 아니라 Oracle의 다른 미들웨어 제품들도 docker image를 생성할 수 있는데요
다음 제품들의 작업이 가능합니다.
