JAVA项目如何通过maven打包成docker的方式推送到docker仓库里面

在生产环境中，现在k8s越来越流行，所以我们日常的项目几乎都是使用docker的方式部署到k8s集群里面的。之前我们介绍过如何把项目进行docker打包，可参考《微服务实战spring cloud alibaba（十三）使用docker部署我们的所有服务》，今天我们直接介绍在项目的maven里面pom.xml里面添加plugin，实现在本地或者jekins上直接把项目打包成docker并推送到docker镜像里面。

我们这里使用的插件是：jlib插件。所以这里我们直接在pom.xml的build的plugins里面添加如下plugin

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>com.google.cloud.tools</groupId>
                <artifactId>jib-maven-plugin</artifactId>
                <version>3.1.4</version>
                <configuration>
                    <!--配置基本镜像-->
                    <from>
                        <image>openjdk:8-jdk-alpine</image>
                        <!-- <image>adoptopenjdk:8-jre</image> 选一个就行，有的镜像方法不全-->
                    </from>
                    <!--配置最终推送的地址，仓库名，镜像名-->
                    <to>
                        <image>docker.io/这里填写docker账户名/仓库名</image>
                        <tags>
                            <tag>v1.1</tag>
                            <tag>latest</tag>
                        </tags>
                        <auth>
                            <username>docker账号</username>
                            <password>密码</password>
                        </auth>
                    </to>
                    <container>
                        <mainClass>com.chunhui.WhatsupMallPlusApplication改成自己的主类</mainClass>
                        <jvmFlags>
                            <jvmFlag>-Xms512m</jvmFlag>
                            <jvmFlag>-Xmx1024m</jvmFlag>
                            <!-- 记录内存溢出时的推展情况-->
                            <jvmFlag>-XX:+HeapDumpOnOutOfMemoryError</jvmFlag>
                            <!-- 内存溢出文件位置-->
                            <jvmFlag>-XX:HeapDumpPath=./</jvmFlag>
                        </jvmFlags>
                        <ports>
                            <port>8090端口号</port>
                        </ports>
                        <!--使用该参数将镜像的创建时间与系统时间对其,不然镜像上传的时间会是四十几年前-->
                        <creationTime>USE_CURRENT_TIMESTAMP</creationTime>
                    </container>
                </configuration>
 
                <!--绑定到maven lifecicle-->
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>build</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

然后我们在idea的maven下面的plugin里面可以看到jlib
