4장. WebLogic Image Tool을 활용한 WebLogic Docker Image로 운영환경 구성하기 - Managed_Server 구성

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.

[root@middleware-works-centos8 wls14c]# docker image ls
REPOSITORY                   TAG               IMAGE ID       CREATED       SIZE
wls                          14.1.1.0.0-slim   b107ac6eb4eb   6 days ago    1.02GB
wls                          14.1.1.0.0        033e6f70ff0f   6 days ago    1.39GB
wls                          12.2.1.3.0        d4374a78436c   6 days ago    1.36GB
ghcr.io/oracle/oraclelinux   8-slim            c7c0b3ae3077   4 weeks ago   101MB

WebLogic 14c(14.1.1.0.0) slim 기본 이미지(Image Id: b107ac6eb4eb)로 컨테이너 구동 후 managed로 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. 9002 port: managed server port

 

우선 managed server로 사용할 컨테이너를 기동 합니다.

다음 옵션으로 실행해 줍니다.

docker container run --name wls_slim -d -p 9002:9002 -it -v $PWD/properties:/u01/oracle/properties -v $PWD/domains:/u01/oracle/domains b107ac6eb4eb

[root@middleware-works-centos8 wls14c]# pwd
/home/opc/docker_datas/wls14c
[root@middleware-works-centos8 wls14c]# ls
docker_run_container.sh  domains  properties  wls_admin.sh  wls_managed.sh
[root@middleware-works-centos8 wls14c]# cat wls_managed.sh
#!/bin/bash
 
# 14c normal
#docker container run --name wls_admin -d -p 7001:7001 -it -v $PWD/properties:/u01/oracle/properties -v $PWD/domains:/u01/oracle/domains 033e6f70ff0f
 
# 14c slim
docker container run --name wls_slim -d -p 9002:9002 -it -v $PWD/properties:/u01/oracle/properties -v $PWD/domains:/u01/oracle/domains b107ac6eb4eb
 
#docker container run --name wls_admin -d -p 7001:7001 -p 9002:9002 -it -v $PWD:/u01/oracle/properties -e ADMINISTRATION_PORT_ENABLED=true -e DOMAIN_NAME=docker_domain -e ADMIN_NAME=docker-AdminServer 033e6f70ff0f
[root@middleware-works-centos8 wls14c]# ./wls_managed.sh
99d80dfef4329bc382827598a9ae1a9e11e020b3f4f5d3fbaff6db6428560213
[root@middleware-works-centos8 wls14c]# docker ps -a
CONTAINER ID   IMAGE          COMMAND       CREATED             STATUS             PORTS                    NAMES
99d80dfef432   b107ac6eb4eb   "/bin/bash"   4 seconds ago       Up 3 seconds       0.0.0.0:9002->9002/tcp   wls_slim
e4fdcdde81ee   033e6f70ff0f   "/bin/bash"   About an hour ago   Up About an hour   0.0.0.0:7001->7001/tcp   wls_admin

docker ps 명령으로 정상적으로 컨테이너가 실행된 것이 확인됩니다.

---

2. WebLogic Managed 구성

실행된 컨테이너로 접속하여 WebLogic managed를 구성해 보겠습니다.

 

사실 여기서부터는 On-Prem환경과 다른 부분이 없습니다만 docker container로도 정상적으로 동작하는 것을 확인하기 위해 진행하도록 하겠습니다.

 

다음 명령으로 container에 접속 후 StartNodeMonager.sh 파일을 실행합니다.

docker exec -it wls_slim /bin/bash

컨테이너 접속 후

/u01/oracle/domains/docker_domain/bin/StartNodeManager.sh 파일 실행

[root@middleware-works-centos8 wls14c]# docker ps -a
CONTAINER ID   IMAGE          COMMAND       CREATED             STATUS             PORTS                    NAMES
99d80dfef432   b107ac6eb4eb   "/bin/bash"   2 minutes ago       Up 2 minutes       0.0.0.0:9002->9002/tcp   wls_slim
e4fdcdde81ee   033e6f70ff0f   "/bin/bash"   About an hour ago   Up About an hour   0.0.0.0:7001->7001/tcp   wls_admin

%DOMAIN_HOME/nodemanager/nodemanager.properties  파일을 수정해 줍니다.

 

SSL 인증서가 없으니 17번째 라인 'SecureListener' 항목을 'false'로 변경 후 저장합니다.

NodeManager 실행이 완료되면 웹로직 콘솔로 돌아와 시스템을 구성해 줍니다.

 

참고로 Container 간의 통신을 위해서는 다음과 같이 docker network 작업이 진행되어야 합니다.

(Admin 서버와 node manager 간의 통신을 위해 사용)

docker network create wls-network
docker network connect wls-network wls_admin
docker network connect wls-network wls_slim

[root@middleware-works-centos8 wls14c]# docker network create wls-network

Node manager가 확인 되었습니다.

WebLogic NodeManager 등록완료

 

Node manager 등록이 완료되었으므로 서버를 생성하고 기동 해 줍니다.

Managed Server 생성

 

생성한 managed 서버를 기동해 줍니다.

Managed Server 기동

 

서버 기동이 완료되었습니다.

Managed Server 기동완료

서버 기동 완료 후 접근 확인입니다.

배포된 App이 없어 404 페이지가 뜨고 있지만 slim 버전의 docker image로 서비스가 가능한 것을 확인할 수 있었습니다.

Managed Server 확인

여기까지 WebLogic Image Tool을 사용하여 WebLogic docker image를 생성하고 운영환경에 구성하는 방법을 알아보았습니다.

 

타 WAS 대비 강력한 기능을 제공하는 WebLogic도 이제 container 환경에서 사용이 가능하며, managed 서버의 경우 slim image를 사용하면 불필요한 용량을 줄일 수 있어 이러한 구조에서는 활용 의미가 있을 것 같습니다.
