Jenkins结合Gitlab，实现镜像构建及推送

docker-compose

jenkins的docker-compose目录为为/home/jenkins，这个后面写脚本的时候需要对应上

version: '3'
services:
  docker_jenkins:
    restart: always
    image: jenkins/jenkins:lts
    container_name: docker_jenkins
    privileged: true 
    ports:
      - '8080:8080'
      - '50000:50000'
    volumes:
      - ./data/:/var/jenkins_home
      - /var/run/docker.sock:/var/run/docker.sock
      - /usr/bin/docker:/usr/bin/docker
      - /usr/lib/x86_64-linux-gnu/libltdl.so.7:/usr/lib/x86_64-linux-gnu/libltdl.so.7

授权目录

1. chmod 777 ./data -R
2. chmod 777 /var/run/docker.sock （设置宿主机可执行，因为进入jenkins容器还会使用宿主机docker）

安装插件

1. 搜索安装Git相关插件
2. 搜索安装Gitlab相关插件
3. 搜索安装Docker相关插件

凭据管理

1. Gitlab 用户名密码
2. 推送到阿里云镜像容器，docker login 的用户名密码
   
   

设置时区

System.setProperty('org.apache.commons.jelly.tags.fmt.timeZone', 'Asia/Shanghai')

点击运行

创建流水线

将jenkins生成的webhook地址复制到gitlab中

流水线脚本

下面脚本的/home/jenkins目录，需要指定为宿主机的挂载目录
需要修改credentialsId为自己的gitlab凭证、以及推送到镜像仓库的凭证
需要修改url为项目实际gitlab地址

java项目

node('built-in') { 



	 stage('Git Clone') {
        checkout([$class: 'GitSCM', branches: [[name: "origin/${env.gitlabSourceBranch}"]], extensions: [], userRemoteConfigs: [[credentialsId: 'ld-git', url: 'http://gitlab地址/asterism-back/aip-base.git']]])
	}

	
	stage('DockerPush-ld') {     

		globalDockerRegistry="registry.cn-hangzhou.aliyuncs.com" 
		credentials = "ledison7"
		imageStore="https://registry.cn-hangzhou.aliyuncs.com"
		tenantCode="fireworks" 
		docker.withRegistry(imageStore,credentials) {
		    sh encoding: 'UTF-8', label: 'Maven 缓存构建',script:'''
				docker run -i --rm  -v /home/jenkins/mavenRespo:/var/jenkins_home/mavenRespo  -v /home/jenkins/data/workspace/${JOB_NAME}:/usr/src/mymaven -w /usr/src/mymaven  maven:3.6.3  mvn clean package -DskipTests -s ./go_settings.xml
				sleep 1
		        '''
		
			commitId = "${env.gitlabMergeRequestLastCommit}".substring(0,8)
			imageTag = "registry.cn-hangzhou.aliyuncs.com/fireworks/aip-base:latest"
			sh encoding: 'UTF-8', label: '镜像构建',script:' docker build -t  '+imageTag+' -f Dockerfile . '
			sh encoding: 'UTF-8', label: '镜像推送',script:' docker push '+imageTag 
			sh encoding: 'UTF-8', label: '镜像清理',script:' docker rmi '+imageTag
		} 
	}
