原理：
docker-maven-plugin 調用一個 docker 的api,進行打包鏡像，tag標簽，push到遠程倉庫。
遠程倉庫的密碼,在本地maven 的setting.xml里配置一個server ，idea根據id可以獲取到遠程倉庫的賬號，密碼
一、docker主機開啟docker 遠程訪問API
Ubuntu：
vi /lib/systemd/system/docker.service
Centos7
vi /usr/lib/systemd/system/docker.service
找到ExecStart
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock
修改完后 重置重啟
systemctl daemon-reload
systemctl restart docker
防火牆開放端口:2375
驗證
http://ip:2375/images/json 或 curl http:/ip:2375/info
二、在docker主機配置遠程倉庫地址，以便非https 也能訪問
vi /etc/docker/daemon.json
{ "registry-mirrors": [ "https://dockerhub.azk8s.cn", "https://reg-mirror.qiniu.com" ], "insecure-registries": ["registry1的IP地址:端口號","registry2的IP地址:端口號"] }
修改完后 重置重啟
systemctl daemon-reload
systemctl restart docker
三、maven 配置 遠程倉庫的賬號密碼
編輯 maven settings.xml文件
<server> <id>local_docker</id> <username>lulu</username> <password>123456</password> </server>
四、pom 配置
<properties> <project.name>bluetoothled</project.name> <!-- 私有倉庫配置，需要settings.xml文件配合serverId對應的倉庫服務 賬號密碼 --> <docker.serverId>local_docker</docker.serverId> <docker.registry>192.168.182.100:5000</docker.registry> <docker.host>http://192.168.182.100:2375</docker.host> </properties>
<build> <plugins> <!-- Srping Boot 打包工具 打包成可執行的jar --> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> <!--打包后 復制jar包到指定文件目錄--> <plugin> <artifactId>maven-resources-plugin</artifactId> <version>3.1.0</version> <executions> <execution> <id>copy-resources</id> <!-- here the phase you need --> <phase>validate</phase> <goals> <goal>copy-resources</goal> </goals> <configuration> <!-- 復制資源后的輸出目錄 --> <outputDirectory>target</outputDirectory> <resources> <resource> <directory>src/main/docker</directory> <filtering>true</filtering> </resource> </resources> </configuration> </execution> </executions> <configuration> <encoding>UTF-8</encoding> </configuration> </plugin> <!-- docker插件 --> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>1.2.0</version> <configuration> <!-- 私有倉庫配置，需要settings.xml文件配合serverId對應的服務地址 --> <serverId>${docker.serverId}</serverId> <!-- docker私服地址 --> <registryUrl>${docker.registry}</registryUrl> <!-- 指定docker server的地址，該配置不需要本機安裝docker --> <dockerHost>${docker.host}</dockerHost> <imageName>${project.name}/${project.artifactId}:${project.version}</imageName> <imageTags> <imageTag>${project.version}</imageTag> </imageTags> <!-- docker的構建目錄（構建上下文），包含Dockerfile --> <dockerDirectory>target</dockerDirectory> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> <executions> <!-- package之前清除上一次構建的image --> <execution> <id>remove-image</id> <phase>package</phase> <goals> <goal>removeImage</goal> </goals> <configuration> <imageName> ${project.name}/${project.artifactId} </imageName> <imageTags> <imageTag>${project.version}</imageTag> <imageTag>latest</imageTag> </imageTags> </configuration> </execution> <execution> <id>remove-tag-image</id> <phase>package</phase> <goals> <goal>removeImage</goal> </goals> <configuration> <imageName> ${docker.registry}/${project.name}/${project.artifactId} </imageName> <imageTags> <imageTag>${project.version}</imageTag> <imageTag>latest</imageTag> </imageTags> </configuration> </execution> <!-- 將docker:build綁定到package這個phase --> <execution> <id>build-image</id> <phase>package</phase> <goals> <goal>build</goal> </goals> <configuration> <!-- imageName中若不指定tag，則會打上latest --> <imageName>${project.name}/${project.artifactId}:${project.version}</imageName> <!-- 可以使用<imageTags>標簽打其他額外的tag --> </configuration> </execution> <!-- 將docker:tag綁定到package這個phase --> <execution> <id>tag-image</id> <phase>package</phase> <goals> <goal>tag</goal> </goals> <configuration> <!-- docker tag IMAGE[:TAG] [REGISTRY_HOST[:REGISTRY_PORT]/]REPOSITORY[:TAG] --> <!-- images與IMAGE[:TAG]對應，必須在build階段已經構建了 --> <image>${project.name}/${project.artifactId}:${project.version}</image> <!-- newName與tag命令的第二個參數對應 --> <newName> ${docker.registry}/${project.name}/${project.artifactId}:${project.version} </newName> </configuration> </execution> <execution> <id>tag-image-latest</id> <phase>deploy</phase> <goals> <goal>tag</goal> </goals> <configuration> <!-- docker tag IMAGE[:TAG] [REGISTRY_HOST[:REGISTRY_PORT]/]REPOSITORY[:TAG] --> <!-- images與IMAGE[:TAG]對應，必須在build階段已經構建了 --> <image>${project.name}/${project.artifactId}:${project.version}</image> <!-- newName與tag命令的第二個參數對應 --> <newName> ${docker.registry}/${project.name}/${project.artifactId}:latest </newName> </configuration> </execution> <!-- 將docker:push綁定到deploy這個phase --> <execution> <id>push-image</id> <phase>deploy</phase> <goals> <goal>push</goal> </goals> <configuration> <imageName> ${docker.registry}/${project.name}/${project.artifactId}:${project.version} </imageName> </configuration> </execution> <execution> <id>push-image-latest</id> <phase>deploy</phase> <goals> <goal>push</goal> </goals> <configuration> <imageName> ${docker.registry}/${project.name}/${project.artifactId}:latest </imageName> </configuration> </execution> </executions> </plugin> </plugins> </build>

五、在idea中命令控制台中使用
創建鏡像
mvn clean
package
docker:build
推送鏡像到Registry
mvn clean
package
docker:build -DpushImage
推送指定tag的鏡像到Registry
mvn clean
package
docker:build -DpushImageTag
執行 build、tag、push 操作
mvn deploy
如果想跳過 docker 某個過程時，只需要：
-DskipDockerBuild 跳過 build 鏡像
-DskipDockerTag 跳過 tag 鏡像
-DskipDockerPush 跳過 push 鏡像
-DskipDocker 跳過整個階段
