Idea安装配置docker插件 2.1. idea-plugins市场安装docker插件 略… 2.2. 配置docker 
3.springboot项目部署到docker服务器 3.1. 编写docker/dockerfile 
3.2.maven添加docker-maven-plugin插件 <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>1.0.0</version> <configuration> <!--指定生成的镜像名，如果不指定tag,默认会使用latest--> <imageName>jhs/${project.artifactId}:${project.version}</imageName> <!--添加额外的指定标签, 非必须--> <!-- <imageTags> <imageTag>${project.version}</imageTag> </imageTags> --> <!-- 指定 Dockerfile 路径 ：项目根路径下--> <dockerDirectory>${project.basedir}/docker</dockerDirectory> <!--指定远程 docker api地址--> <dockerHost>http://192.168.129.162:2375</dockerHost> <!-- copy资源 --> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> <!--docker build dockerfile时：设置镜像创建时的变量 --> <buildArgs> <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE> </buildArgs> </configuration> </plugin>3.3. docker:build 使用命令$ mvn clean package docker:build -Dmaven.test.skip=true构建镜像，在docker服务器上查看镜像是否上传成功： 
3.4 docker:tag docker命令行格式为：#docker tag <imageId or imageName> <nexus-hostname>:<repository-port>/<image>:<tag>
插件配置
<configuration>补充配置： <configuration> <image>jhs/${project.artifactId}:${project.version}</image> <!-- docker tag 打标签--> <newName>192.168.129.160:5000/${project.artifactId}:${project.version}</newName></configuration>为镜像打上tag标签，为后续的push做准备：mvn clean docker:tag -Dmaven.test.skip=true -DskipDockerBuild 
3.5 docker:push 插件配置
<configuration>补充配置： <configuration> <!-- docker push 推送到远程镜像仓库--> <!-- serverId: 为在maven setting.xml配置的server信息id--> <serverId>nexus-docker-registry</serverId> <registryUrl>192.168.129.160:5000</registryUrl> <!-- 打上tag的新镜像 push 到nexus--> <imageName>192.168.129.160:5000/${project.artifactId}</imageName></configuration>将上文打上tag标签的镜像，推送到私服nexus：mvn clean docker:push -Dmaven.test.skip=true -DskipDockerBuild -DskipDockerTag 
3.6 docker插件参数 -DskipDockerBuild to skip image build-DskipDockerTag to skip image tag-DskipDockerPush to skip image push-DskipDockerto skip any Docker goals 3.7 绑定命令到maven phases <executions> <execution> <id>build-image</id> <phase>package</phase> <goals> <goal>build</goal> </goals> </execution> <execution> <id>tag-image</id> <phase>package</phase> <goals> <goal>tag</goal> </goals> <configuration> <image>jhs/${project.artifactId}:${project.version}</image> <newName>192.168.129.160:5000/${project.artifactId}:${project.version}</newName> </configuration> </execution> <execution> <id>push-image</id> <phase>deploy</phase> <goals> <goal>push</goal> </goals> <configuration> <!-- docker push 推送到远程镜像仓库--> <!-- serverId: 为在maven setting.xml配置的server信息id--> <serverId>nexus-docker-registry</serverId> <registryUrl>192.168.129.160:5000</registryUrl> <imageName>192.168.129.160:5000/${project.artifactId}</imageName> </configuration> </execution> </executions>3.8 最佳实践 <properties> <docker.host>http://192.168.129.162:2375</docker.host> <docker.registry.url>192.168.129.160:5000</docker.registry.url> </properties> <build> <plugins> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>1.0.0</version> <configuration> <imageName>dic/${project.artifactId}:${project.version}</imageName> <!--添加额外的指定标签（可配置多个）, 若果没做指定，则为latest--> <!-- <imageTags> <imageTag>${project.version}</imageTag> </imageTags> --> <!-- 指定 Dockerfile 路径 ：项目根路径下--> <dockerDirectory>${project.basedir}/docker</dockerDirectory> <!--指定远程 docker api地址--> <dockerHost>${docker.host}</dockerHost> <!-- copy资源 --> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> <!--docker build dockerfile时：设置镜像创建时的变量 --> <buildArgs> <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE> </buildArgs> </configuration> <executions> <execution> <id>build-image</id> <phase>package</phase> <goals> <goal>build</goal> </goals> </execution> <execution> <id>tag-image</id> <phase>package</phase> <goals> <goal>tag</goal> </goals> <configuration> <image>dic/${project.artifactId}:${project.version}</image> <newName>${docker.registry.url}/${project.artifactId}:${project.version}</newName> </configuration> </execution> <execution> <id>push-image</id> <phase>deploy</phase> <goals> <goal>push</goal> </goals> <configuration> <!-- docker push 推送到远程镜像仓库--> <!-- serverId: 为在maven setting.xml配置的server信息id--> <serverId>nexus-docker-registry</serverId> <registryUrl>${docker.registry.url}</registryUrl> <imageName>${docker.registry.url}/${project.artifactId}</imageName> </configuration> </execution> </executions> </plugin> </plugins> </build>4.Docker私服仓库Harbor安装的步骤详解(补充) https://www.jb51.net/article/161964.htm
