안녕하세요. 미들웨어 입니다.
이번 시간에는 Weblogic을 Docker 이미지로 만드는 방법에 대해 핸즈온 가이드를 진행해보겠습니다.
Openshift 의 활용이 늘어나다 보니 Weblogic 을 올리는 경우도 자주 있는데, 최신 버전을 사용해야 하거나, 환경이 오라클 리눅스가 아닐 경우는 원하는 환경으로 이미지를 만들어야 하는 경우가 발생 할 수 있습니다.
##############################
## 1. weblogic Image Tool (WIT) 다운로드
##############################
1. 웹로직 이미지 툴 WIT 다운로드
- 파일 다운로드 후 서버 업로드 (리눅스용 다운)
파일명 : weblogic-image-tool-main.zip (첨부파일로 올려드립니다)
2. WIT 설치 가이드
##############################
## 2. weblogic Image Tool 설치 단계
#############################
package, clean, mvn clean package 빌드 실행, 사전에 MVN은 설치되있어야 합니다
1. 빌드 실행
- 압축해제
unzip weblogic-image-tool-main.zip
- mvn package 실행
mvn package weblogic-image-tool-main
빌드 성공 (스샷)
- 빌드성공하면 아래처럼 /tests/target 디렉토리 생성
[weblogic@weblogic-test weblogic-image-tool-main]$ cd tests/
[weblogic@weblogic-test tests]$ ll

2. imagetool.zip 압축해제
- imagetool 디렉토리 들어가서 imagetool.zip 압축 해제
[weblogic@weblogic-test target]$ unzip imagetool.zip
Archive: imagetool.zip
creating: imagetool/
creating: imagetool/bin/
inflating: imagetool/bin/imagetool.cmd
inflating: imagetool/bin/imagetool.sh
inflating: imagetool/bin/logging.properties
inflating: imagetool/bin/setup.sh

inflating: imagetool/lib/compiler-0.9.10.jar
3. source setup.sh 실행 (imagetool.sh 실행)
- 압축 해제후 /bin 폴더 들어가면 아래와 같은 imagetool.sh, setup.sh 파일 확인
[weblogic@weblogic-test bin]$ pwd
/home/weblogic/weblogic-image-tool-main/installer/target/imagetool/bin
[weblogic@weblogic-test bin]$ ll
total 16
-rwxr-x---. 1 weblogic weblogic 972 Oct 7 21:44 imagetool.cmd
-rwxr-x---. 1 weblogic weblogic 1121 Oct 7 21:44 imagetool.sh
-rwxr-x---. 1 weblogic weblogic 1132 Oct 7 21:44 logging.properties
-rwxr-x---. 1 weblogic weblogic 1216 Oct 7 21:44 setup.sh
- source setup.sh 실행
(java 환경변수 설정)
Please set the JAVA_HOME environment variable to match the location of your Java installation. Java 8 or newer is requiredzz
4. JAVA 환경변수를 .bash_profile 등록
export JAVA_HOME=/usr
PATH=$PATH:$HOME/.local/bin:$HOME/bin:$MAVEN_HOME/bin:$JAVA_HOME/bin
- source setup.sh 실행
- imagetool.sh 실행 (스샷 참고)
[weblogic@weblogic-test bin]$ ./setup.sh
[weblogic@weblogic-test bin]$ ./imagetool.sh
##############################
## 3. imagetool 명령어로 이미지 생성
#############################
1. java, weblogic 다운로드
설치 프로그램을 다운로드 한뒤 원하는 경로에 저장해둔다
경로 : /home/weblogic/install
[weblogic@weblogic-test install]$ ll
total 5867356
-rw-rw-r--. 1 weblogic weblogic 1635717400 Sep 1 19:59 fmw_12.2.1.4.0_infrastructure_Disk1_1of1.zip
145520298 Oct 7 23:10 jdk-8u301-linux-x64.tar.gz
2. 캐시툴 사용 (Cache Tool to add the installzzers)
위에 저장했던 경로와 파일명을 입력해줍니다.
- imagetool 명령어
imagetool cache addInstaller --type jdk --version 8u202 --path /home/weblogic/install/jdk-8-linux-x64.tar.gz
imagetool cache addInstaller --type wls --version 12.2.1.3.0 --path /home/weblogic/install/fmw_12.2.1.4.0_infrastructure_Disk1_1of1.zip
- 실행 (Successfully added to cache)
[weblogic@weblogic-test bin]$ imagetool cache addInstaller --type jdk --version 8u202 --path /home/weblogic/install/jdk-8-linux-x64.tar.gz
[INFO ] Successfully added to cache. jdk_8u202=/home/weblogic/install/jdk-8-linux-x64.tar.gz

[INFO ] Successfully added to cache. wls_12.2.1.3.0=/home/weblogic/install/fmw_14.1.1.0.0_wls_lite_generic.jar
[weblogic@weblogic-test bin]$
3. 캐시 항목 확인 (imagetool cache listItems)
[weblogic@weblogic-test bin]$ imagetool cache listItems
Cache contents
cache.dir=/home/weblogic/cache
jdk_8u202=/home/weblogic/install/jdk-8-linux-x64.tar.gz
wls_12.2.1.3.0=/home/weblogic/install/fmw_12.2.1.4.0_infrastructure_Disk1_1of1.zip
4. docker 설치 및 실행
docker 사전 설치되있어야 합니다.
설치는 아래 내용 참고
- docker 설치
sudo yum install docker
sudo yum install docker-registry
- docker 자동실행 등록
sudo systemctl enable docker.service

Weblogic 에서 openshift 나 쿠버네티스에서 사용 할 수 있는 이미지를 생성 하는 방법에 대해 가이드 해봤습니다.
그럼 ...열공하세요~~
