项目相关信息

创建Dockerfile文件

目录结构如下：

Docker内容如下：

FROM java:8
ADD ./docker-0.0.1.jar  ./app.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "./app.jar"]

项目pom.xml文件信息

pom.xml文件基本内容：

在pom文件中添加docker-plugin相关信息：

此方式依赖Dockerfile

<plugin>
  <groupId>com.spotify</groupId>
  <artifactId>docker-maven-plugin</artifactId>
  <version>0.4.13</version>
  <configuration>
    <imageName>${project.build.finalName}</imageName>
    <dockerDirectory>./</dockerDirectory>
    <resources>
      <rescource>
        <targetPath>/</targetPath>
        <directory>${project.build.directory}</directory>
        <include>${project.build.finalName}.jar</include>
      </rescource>
    </resources>
  </configuration>
  <executions>
    <execution>
      <phase>install</phase>
      <goals>
        <goal>build</goal>
      </goals>
    </execution>
    <execution>
      <id>tag-image</id>
      <phase>install</phase>
      <goals>
        <goal>tag</goal>
      </goals>
      <configuration>
        <image>${project.build.finalName}</image>
        <newName>${repository.url}/${project.build.finalName}</newName>
      </configuration>
    </execution>
    <execution>
      <id>push-image</id>
      <phase>install</phase>
      <goals>
        <goal>push</goal>
      </goals>
      <configuration>
        <imageName>${repository.url}/${project.build.finalName}</imageName>
      </configuration>
    </execution>
    <execution>
      <id>push-image</id>
      <phase>install</phase>
      <goals>
        <goal>push</goal>
      </goals>
      <configuration>
        <imageName>${docker.repository}/${project.build.finalName}</imageName>
      </configuration>
    </execution>
  </executions>
</plugin>

在pom文件中配置Dockerfile相关信息(即可以不配置之前提到的Dockerfile)：

此方式不依赖Dockerfile

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <version>0.4.13</version>
    <configuration>
        <imageName>${project.build.finalName}</imageName>
        <dockerDirectory>./</dockerDirectory>
        <baseImage>java:8</baseImage>
        <cmd>["java", "-version"]</cmd>
        <entryPoint>["java", "-jar", "${project.build.finalName}.jar"]</entryPoint>
        <resources>
            <rescource>
                <targetPath>/</targetPath>
                <directory>${project.build.directory}</directory>
                <include>${project.build.finalName}.jar</include>
            </rescource>
        </resources>
    </configuration>
    <executions>
        <execution>
            <phase>install</phase>
            <goals>
                <goal>build</goal>
            </goals>
        </execution>
        <execution>
            <id>tag-image</id>
            <phase>install</phase>
            <goals>
                <goal>tag</goal>
            </goals>
            <configuration>
                <image>${project.build.finalName}</image>
                <newName>${repository.url}/${project.build.finalName}</newName>
            </configuration>
        </execution>
        <execution>
            <id>push-image</id>
            <phase>install</phase>
            <goals>
                <goal>push</goal>
            </goals>
            <configuration>
                <imageName>${repository.url}/${project.build.finalName}</imageName>
            </configuration>
        </execution>
    </executions>
</plugin>
