docker-compose安装jenkins

1、环境准备：准备安装好docker的服务器一台
2、在服务器上创建一个目录用于安装Jenkins

mkdir jenkins

3、下载好要挂载的：maven、jkd；并将下载好的tar.gz包上传至服务器待安装目录中并解压

tar -xzvf tar -xzvf apache-maven-3.9.6-bin.tar.gz
tar -xzvf graalvm-jdk-21_linux-x64_bin.tar.gz

在这里插入图片描述

4、修改解压后maven中的setting配置文件
主要修改仓库存储路径和镜像仓库

    <localRepository>/root/jenkins/repo</localRepository>
    <!-- 配置阿里云镜像地址 -->
    <mirror>
      <id>alimaven</id>
      <name>aliyun maven</name>
      <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
     <mirrorOf>central</mirrorOf>
    </mirror>

5、配置maven和jdk的PATH挂载文件，git用系统默认的就行，不需要额外配置

mkdir -p ~/jenkins/conf
vi profile

profile内容

export MAVEN_HOME=/usr/local/maven/apache-maven-3.9.6
export PATH=$MAVEN_HOME/bin:$PATH
export JAVA_HOME=/usr/local/java/graalvm-jdk-21.0.2+13.1
export PATH=$JAVA_HOME/bin:$PATH

6、配置jenkins的docker-compose.yml文件

version: '3.9'

services:
  jenkins:
    image: jenkins/jenkins:2.440.2
    container_name: jenkins
    user: root
    restart: always
    deploy:
      resources:
        limits:
          cpus: '1.00'
          memory: 1G
        reservations:
          cpus: '0.10'
          memory: 256M
    ports:
      - "8080:8080"
      - "50000:50000"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /usr/bin/docker:/usr/bin/docker
      - ./data:/var/jenkins_home
      - ./apache-maven-3.9.6:/usr/local/maven/apache-maven-3.9.6
      - ./graalvm-jdk-21.0.2+13.1:/usr/local/java/graalvm-jdk-21.0.2+13.1
      - ./conf/profile:/root/.bashrc
    environment:
      - TZ=Asia/Shanghai
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:8080/login"]
      interval: 30s
      timeout: 10s
      retries: 8
      start_period: 60s

7、启动好后访问，跟随引导安装推荐插件和创建账户

8、配置环境变量，只需配置：系统管理–全局属性–环境变量：PATH
path获取方法：进入Jenkins的docker中进行获取

docker exec -it jenkins bash
echo $PATH

PATH变量

/usr/local/java/graalvm-jdk-21.0.2+13.1/bin:/usr/local/maven/apache-maven-3.9.6/bin:/opt/java/openjdk/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

配置完成后截图：

9、访问403异常错误排查：
MESSAGE: No valid crumb was included in the request
在这里插入图片描述
处理办法：
将【启用代理兼容】勾上
10、新建一个流水线任务并配置pipeline脚本：

pipeline {
    agent any

    stages {
        
        stage('开始') {
            // 开始
            steps {
              echo "开始"
            }
        }
        
        stage('环境检测') {
            steps {
                
                // 构建环境检测
                sh '''
                     cat /proc/version
                     free -m
                     df -h
                     docker -v
                     git -v
                     mvn -v
                     java -version
                   '''
                 echo 'Hello jenkins'
                 
            }
        }
        
        stage('你好 jenkins') {
            // 结束
            steps {
              echo "结束"
            }
        }
        
    }
}
