timedatectl
sudo timedatectl set-timezone Asia/Seoul
Time zone: Asia/Seoul (KST, +0900)

Jenkins 에 Dockerfile과 docker-compose.yml 파일 세팅

• docker-compose.yml

services:
  jenkins:
    build: .
    container_name: jenkins
    ports:
      - "7070:8080"
      - "50000:50000"
    user: root
    volumes:
      - ./volumes/jenkins:/var/jenkins_home
      - /var/run/docker.sock:/var/run/docker.sock
      - /etc/localtime:/etc/localtime:ro         # 로컬 시간 설정
    environment:
      - TZ=Asia/Seoul                            # 로컬 시간 설정
    restart: unless-stopped

• Dockerfile

# ~/jenkins/Dockerfile
FROM jenkins/jenkins:lts-jdk17

USER root

Jenkins Container 접속

• 초기비밀번호 확인: docker exec -it jenkins cat /var/jenkins_home/secrets/initialAdminPassword
• http://EC2-IP:7070 접속하여 초기비밀번호 입력
• 플러그인 자동 설치 후 몇 분간 대기
