[Jenkins] Docker로 Jenkins 빌드 및 설치
계속 미뤄왔던 젠킨스 도입.
지속적인 빌드와 배포 자동화를 의미하는 CI/CD 쪽에서 jenkins는 대다수 개발자들이 이용하는 툴이다.
매번 war 수동으로 말아서 서버로 밀어 넣고 restart 하는 삶은 이제 그만,,
한번 공부하고 써보자! 무중단배포하는 그날까지~~~~~~~
1. 공식 이미지 존재 여부 확인
docker hub에 Jenkins 공식 이미지가 존재한다.

2. Volume 폴더 생성
jenkins 폴더에 접근할 수 있도록 volume 폴더를 만들고 권한을 주자
$ mkdir -p /opt/docker/volume/jenkins && chmod -R 777 "$_"
3. Dockerfile 생성
FROM jenkins/jenkins:centos7
USER root일단 dockerfile쪽은 작성할 게 별로 없는데 나중에 추가하도록 하자
추가.
FROM jenkins/jenkins:centos7
#metadata
LABEL name="minggu"
LABEL email="minha1002@gmail.com"
LABEL description="jenkins test"
USER root
# Install docker
RUN yum update -y && yum install -y docker wget
4. docker-compose.yml
# docker-compose.yml
version: "3.8"
services:
wildfly:
...
jenkins:
container_name: jenkinsC
enviroment:
TZ: "Asia/Seoul"
build:
context: ./dockerfiles/jenkins/
dockerfile: jenkins.Dockerfile
ports:
- 5080:8080
- 50000:50000
volumes:
- /opt/docker/volume/jenkins:/var/jenkins_home
- /var/run/docker.sock:/var/run/docker.sock저번에 만들어 둔 wildfly 밑에 새로 jenkins라는 이름의 service를 만들었다. 간단간단
5. docker compose up을 통한 build
#특정 service 명 입력

혹시라도 background로 docker를 실행했다면 docker logs [docker name]으로 로그를 다시 찍어보면 된다.
6. jenkins console 접속
아까 열어둔 서버:5080 포트로 접속해보면
짜잔 접속이 된다.
방금 전 패스워드를 입력하고
플러그인을 설치해주자.
admin 계정을 생성해주고 고정 URL을 정해주면
