1.修改linux服务器docker配置文件

vim  /usr/lib/systemd/system/docker.service

添加配置

ExecStart=/usr/bin/dockerd

-H fd:// --containerd=/run/containerd/containerd.sock  

-H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

重启docker

systemctl daemon-reload

systemctl restart docker

2.Idea下载docker插件

3.修改项目pom文件

 <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.4.1</version>
 
                <configuration>
                    <fork>true</fork>
                    <addResources>true</addResources>
                    <mainClass>com.Main8090</mainClass>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>1.0.0</version>
                <!--将插件绑定在某个phase执行-->
                <executions>
                    <execution>
                        <id>build-image</id>
                        <!--将插件绑定在package这个phase上。也就是说，用户只需执行mvn package ，就会自动执行mvn docker:build-->
                        <phase>package</phase>
                        <goals>
                            <goal>build</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <!--指定生成的镜像名 ${project.artifactId} -->
                    <imageName>idea2021test</imageName>
                    <!--指定标签-->
                    <imageTags>
                        <imageTag>latest</imageTag>
                    </imageTags>
                    <!-- 指定 Dockerfile 路径 ${project.basedir}：项目根路径下-->
                    <dockerDirectory>${project.basedir}</dockerDirectory>
                    <!--指定远程 docker api地址-->
                    <dockerHost>http://101.200.201.196:2375</dockerHost>
                    <!-- 这里是复制 jar 包到 docker 容器指定目录配置 -->
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <!--jar 包所在的路径 此处配置的 即对应 target 目录-->
                            <directory>${project.build.directory}</directory>
                            <!-- 需要包含的 jar包 ，这里对应的是 Dockerfile中添加的文件名　-->
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                    <!-- 以下两行是为了docker push到DockerHub使用的。 -->
                    <!--<serverId>docker-hub</serverId>-->
                    <!--<registryUrl>https://index.docker.io/v1</registryUrl>-->
                </configuration>
            </plugin>
        </plugins>
    </build>

4.打包、build

表示build成功

5.创建容器

6.配置映射端口

7.运行
