docker-compose安装jenkins全过程_云虚拟主机

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

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

补充：

以上配置在jenkins中执行mvn -v命令查看mvn对应的java版本时，发现还是旧的版本，跟挂载的版本不一致，这是因为jenkins去执行时使用的是jenkins启动时的java_home导致的，此时需要增加下环境变量进行覆盖就可

查看镜像设置的java_home

docker  inspect jenkins/jenkins:2.440.2

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

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"
            }
        }
        
    }
}
