          <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
      </properties>
    </profile>

安装 jenkins

• 拉取Jenkins镜像

  docker pull jenkins/jenkins
  

• 编写docker-compose.yml

  version: "3.1"
  services:
    jenkins:
      image: jenkins/jenkins
      container_name: jenkins
      ports:
        - 8080:8080
        - 50000:50000
      volumes:
        - ./data/:/var/jenkins_home/
  

• 启动容器

  docker-compose up -d
  

• error

  touch: cannot touch '/var/jenkins_home/copy_reference_file.log': Permission denied
  

  chmod -R 777 data

  ---

设置SSH service

CI

• 新建任务
  1. 源码管理
     
  2. Build Steps
  3. 构建后操作
  4. Dockerfile

  FROM adoptopenjdk/openjdk8
  COPY demo.jar /usr/local
  WORKDIR /usr/local
  CMD java -jar demo.jar
  

  5. docker-compose.yml

  version: '3.1'
  services:
    demo:
      build: ./
      image: demo:v1.1.0
      container_name: demo
      ports:
      - 8081:8081
  

CD

• 安装 git插件

• 配置Git参数

• 在执行build 前添加执行 shell命令

• error

    stderr: fatal: unable to access 'https://gitee.com/wuyc12138/demo.git/': Could not resolve host: gitee.com
  

  解决

  docker exec -it jenkins bin/bash
  git config --global http.sslVerify false
  

• Jenkins[docker]使用宿主机的docker

  sudo chown root:root /var/run/docker.sock
  sudo chmod o+rw /var/run/docker.sock
  

  • 添加数据卷

    version: "3.1"
    services:
      jenkins:
        image: jenkins/jenkins
        container_name: jenkins
        ports:
          - 8080:8080
          - 50000:50000
        volumes:
          - ./data/:/var/jenkins_home/
          - /usr/bin/docker:/usr/bin/docker
          - /var/run/docker.sock:/var/run/docker.sock
          - /etc/docker/daemon.json:/etc/docker/daemon.json
