reference

1. dockerize node app

2. Jenkins 구성 (docker 기반)

  • docker network 생성 (작업 디렉토리 jenkins)
mkdir jenkins
cd jenkins
docker network create jenkins
  • jenkins Dockerfile 구성
# jenkins/Dockerfile
FROM jenkins/jenkins:latest AS docker
USER root
RUN apt-get update && apt-get install -y lsb-release

# blueocean은 필요시 추가 설치
FROM kustomize AS jenkins
USER jenkins
RUN jenkins-plugin-cli --plugins "docker-workflow:1.26"
  • docker image build
docker build -t jenkins-server:1.0 .
  • docker compose 구성
