使用Jenkins和dockerfile-maven-plugin部署專案

Jenkins節點：

博主的專案目錄結構

在springboot子模塊的pom檔案添加plugin（我這里是在dockerfile-maven-plugin的pom中添加的）

<build>
    <finalName>${project.artifactId}</finalName>
    <plugins>
        <plugin>
            <groupId>com.spotify</groupId>
            <artifactId>dockerfile-maven-plugin</artifactId>
            <version>1.4.13</version>
            <configuration>
                <repository>${project.build.finalName}</repository>
                <tag>${project.version}</tag>
                <buildArgs>
                    <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
                </buildArgs>
            </configuration>
        </plugin>
    </plugins>
</build>

如果父模塊中沒有引入mvn plugin的話這里還需要引入（我這里父級目錄以及包含了這個plugin）

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <version>${frame-version}</version>
    <executions>
        <execution>
            <goals>
                <goal>repackage</goal>
            </goals>
        </execution>
    </executions>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.1</version>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
    </configuration>
</plugin>

專案子模塊根目錄下創建dockerfile

FROM openjdk:8-alpine3.9
MAINTAINER my dockerfile-maven-plugin "chris"
#修改源
RUN echo "http://mirrors.aliyun.com/alpine/latest-stable/main/" > /etc/apk/repositories && \
    echo "http://mirrors.aliyun.com/alpine/latest-stable/community/" >> /etc/apk/repositories
#安裝軟體
RUN apk --update add curl bash tzdata && \
    rm -rf /var/cache/apk/*
#修改時區
ENV TZ Asia/Shanghai
#spring專案暴露的埠
EXPOSE 8091
#傳入一個引數JAR_FILE
ARG JAR_FILE
#把本地檔案JAR_FILE復制到docker中改名為app.jar，上面的pom檔案已經傳入了<JAR_FILE>
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-jar","/app.jar"]

先在本地mvn package一下看看能不能打包

把專案推送到git
進入Jenkins配置流水線

pipeline {
	//執行腳本的agent服務器名
    agent {
        label 'agent-131'
    }
    stages {
        stage('環境驗證') {
            steps {
                sh label: '',
                script: '''java -version
                        docker -v
                        git version
                        mvn -v
                        '''
            }
        }
        stage('拉取代碼') {
            steps {
            	//可以參考https://blog.csdn.net/weixin_41029286/article/details/117607238拉取代碼
                echo '拉取代碼'
            }
        }
        stage('mvn打包') {
            steps {
                //我這里是多級目錄的專案，先cd到子模塊
                sh label: '', script: '''cd chris-framework-devops/dockerfile-maven-plugin/
                pwd
                mvn clean package'''
            }
        }
        stage('洗掉容器') {
            steps {
				sh label: '', script: '''echo \'檢查容器是否存在\'
				containerid=`docker ps -a | grep -w dockerfile-maven-plugin | awk \'{print $1}\'` 
				if [ "$containerid" != "" ];then
					echo ‘容器存在，停止容器’ 
					docker stop $containerid 
					echo ‘洗掉容器’
					docker rm $containerid
				fi'''
            }
        }
        stage('洗掉鏡像') {
            steps {
                sh label: '', script: '''echo \'檢查鏡像是否存在\'
                imageid=`docker images | grep dockerfile-maven-plugin | awk \'{print $3}\'` 
                if [ "$imageid" != "" ];then
                	echo \'洗掉鏡像\'
                	docker rmi -f  $imageid
                fi'''
            }
        }
        stage('構建鏡像') {
            steps {
            	//cd到子模塊，子模塊中要引入dockerfile-maven-plugin不然會報錯No plugin found for prefix 'dockerfile' in the current project
                sh label: '', script: '''cd chris-framework-devops/dockerfile-maven-plugin/
                pwd
                mvn dockerfile:build'''
            }
        }
       	stage('啟動容器') {
            steps {
                sh label: '', script: 'docker run -itd --name=dockerfile-maven-plugin -p 8091:8091 dockerfile-maven-plugin:1.0-SNAPSHOT '
            }
        }
    }
}

保存流水線并構建

測驗一下
