docker-maven-plugin是spotify出品的一款针对spring boot项目的docker插件,可将spring boot项目打包到docker镜像中。

如果在编译docker镜像时需要设置build arg,只需要在maven的配置文件pom.xml中,configuration下增加buildArgs。标签的key和值对应build arg的key和值,如下所示,docker镜像编译过程中,会有一个build arg名为ARG_TIME_ZONE,而其值则为OS的环境变量TIME_ZONE。

  <build>
    <plugins>
      <plugin>
        <groupId>com.spotify</groupId>
        <artifactId>docker-maven-plugin</artifactId>
        <version>0.4.13</version>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>build</goal>
            </goals>
          </execution>
        </executions>
        <configuration>
          <imageName>${docker.registry.name}/${project.artifactId}:latest</imageName>
          <dockerDirectory>src/main/docker</dockerDirectory>
          <buildArgs>
            <ARG_TIME_ZONE>${env.TIME_ZONE}</ARG_TIME_ZONE>
          </buildArgs>
          <resources>
            <resource>
              <targetPath>/</targetPath>
              <directory>${project.build.directory}</directory>
              <include>${project.build.finalName}.jar</include>
            </resource>
          </resources>
        </configuration>
      </plugin>
    </plugins>
  </build>
