安装

使用docker 安装

# 拉取jenkins镜像
[ashsh@pro-data-sh002 ~]$ docker pull jenkinsci/blueocean

# 运行镜像
[ashsh@pro-data-sh002 jenkins]$ docker run \
  -u root \
  --rm \
  -d \
  -p 9089:8080 \
  -p 50000:50000 \
  -v /mnt/app/server/jenkins/data:/var/jenkins_home \
  -v /mnt/app/server/maven/apache-maven-3.1.1:/mnt/app/server/maven/apache-maven-3.1.1 \
  -v /usr/java/jdk1.8.0_181-cloudera:/usr/java/jdk1.8.0_181-cloudera \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v $(which docker):/usr/bin/docker \
  jenkinsci/blueocean

安装后引导

第一次访问新的Jenkins实例时，系统会要求您使用自动生成的密码对其进行解锁。

1. 浏览到 http://localhost:8080（或安装时为Jenkins配置的任何端口），并等待 解锁 Jenkins 页面出现。

1. 从Jenkins控制台日志输出中，复制自动生成的字母数字密码（在两组星号之间）

Maven项目接入Jenkins

pom.xml

pom文件中添加maven docker的打包插件

<!-- Docker maven plugin -->
	<build>
		<plugins>
			<plugin>
				<groupId>com.spotify</groupId>
				<artifactId>docker-maven-plugin</artifactId>
				<version>1.0.0</version>
				<configuration>
					<imageName>${project.artifactId}</imageName>
					<dockerDirectory>src/main/docker</dockerDirectory>
					<resources>
						<resource>
							<targetPath>/</targetPath>
							<directory>${project.build.directory}</directory>
							<include>${project.build.finalName}.jar</include>
						</resource>
					</resources>
				</configuration>
			</plugin>

			<plugin>
				<groupId>com.spotify</groupId>
				<artifactId>dockerfile-maven-plugin</artifactId>
				<version>1.4.13</version>
				<configuration>
					<repository>${project.artifactId}</repository>
				</configuration>
			</plugin>
		</plugins>
	</build>

dockerfile

供maven 插件编译docker镜像使用

FROM java:openjdk-8-jre-alpine

# 定义环境变量
ENV APP_NAME foreign-api-1.0-SNAPSHOT # 项目名
ENV BUILD_ENV ashsh_dev				 # 启动环境
ENV LOCAL_PATH /opt/${APP_NAME}		# 镜像工作目录

# 制作镜像运行命令
RUN mkdir -p ${LOCAL_PATH} /opt/logs/foreign-api/test # 创建所需的目录
RUN apk --no-cache add curl								# 添加curl 工具， 健康检查用（openjdk-8 镜像默认不带curl）
RUN echo 'Asia/Shanghai' >/etc/timezone				# 修改镜像时区

ADD target/${APP_NAME}.jar ${LOCAL_PATH}  		# 启动jar文件

# 设置工作目录
WORKDIR ${LOCAL_PATH}

# 启动命令
CMD java  -Xms800m -Xmx1662m -XX:PermSize=256m -XX:MaxPermSize=1024m -XX:MaxNewSize=1024m -jar ${APP_NAME}.jar --spring.cloud.nacos.config.namespace=${BUILD_ENV}

jenkinsfile

定义 jenkins 脚本执行流程

def project_url = "http://2587984bx6.zicp.vip/java-export/shenshen-export.git"
def project_name = "foreign-api"
def branch_name = "*/dev"
def gitlab_auth = "71e9f234-d159-4ac6-ab42-d031fb02d0a9"
def tag = "latest"
def harbor_address = "172.19.166.202/library"
def image_name = "${harbor_address}/${project_name}:${tag}"
def webhook_url = "http://139.196.179.174:9000/api/webhooks/dc3ac6a1-3c6c-4d39-af3c-be9a082a9651"

node {
    def mvnHome
    stage('拉取代码') { // for display purposes
        checkout(
            [
                $class: 'GitSCM',
                branches: [[name: "${branch_name}"]],
                extensions: [],
                userRemoteConfigs: [
                    [
                        credentialsId: "${gitlab_auth}",
                        url: "${project_url}"
                    ]
                ]
            ]
        )
    }
    stage('构建代码') {
        sh "mvn clean package -DskipTests dockerfile:build"
        sh "docker tag ${project_name} ${image_name}"
    }
    stage('推送镜像') {
        sh "docker login -u $user -p $passwd 172.19.xxx.xxx"
        sh "docker push ${image_name}"
        sh "curl -X POST ${webhook_url}"
    }
}
