안녕하세요.
'수상한 김토끼' 입니다.
Oracle의 WebLogic Image Tool을 활용하여 WebLogic Docker Image를 만들고 운영환경 구성하기입니다.
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. WebLogic Docker Container 실행
앞장에서 WebLogic Image Tool을 활용해 WebLogic의 docker image를 생성하였습니다.
이번에는 생성된 docker image를 사용하여 운영환경을 구성해 보도록 하겠습니다.
우선 사용하고자 하는 docker image를 확인합니다.

WebLogic 14c(14.1.1.0.0) 기본 이미지(Image Id: 033e6f70ff0f)로 컨테이너 구동 후 admin으로 사용하겠습니다.
Docker 명령을 자세히 다루지는 않겠습니다만, 관련 내용을 그대로 따라 하시면 구성이 가능합니다.
Docker 환경에서 사용되는 옵션은 다음과 같습니다.
1. domain_home: WebLogic domain home directory로 사용될 경로
2. properties: domain.properties 파일
3. 7001 port: admin port
우선 admin server로 사용할 컨테이너를 기동 합니다.
다음 옵션으로 실행해 줍니다.
docker container run --name wls_admin -d -p 7001:7001 -it -v $PWD/properties:/u01/oracle/properties -v $PWD/domains:/u01/oracle/domains 033e6f70ff0f|

docker ps 명령으로 정상적으로 컨테이너가 실행된 것이 확인됩니다.
2. WebLogic Admin 구성
실행된 컨테이너로 접속하여 WebLogic admin을 구성해 보겠습니다.
사실 여기서부터는 On-Prem환경과 다른 부분이 없습니다만 docker container로도 정상적으로 동작하는 것을 확인하기 위해 진행하도록 하겠습니다.
다음 명령으로 container에 접속합니다.
docker exec -it wls_admin /bin/bash|

Console에 접속 해 보겠습니다.
Domain 구성시 사용한 name, password를 입력 후 로그인합니다.
로그인에 성공하였습니다.
위와 같이 볼륨 마운트 방식으로 container를 구성하면 docker종료 후 재 실행 시에도 아무 문제없이 기존 domain구성을 활용할 수 있습니다.
여기까지 이번장을 마치고 다음 장에서는 managed server 구성에 대해 알아보도록 하겠습니다.
