Question

我尝试使用spotify / docker-maven-plugin失败，

下面是我pom.xml文件的一部分

<plugin>
  <groupId>com.spotify</groupId>
  <artifactId>docker-maven-plugin</artifactId>
  <version>${dockerfile-maven-version}</version>
  <executions>
    <execution>
      <id>default</id>
      <goals>
        <goal>build</goal>
        <goal>push</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <repository>myrepo/maven-docker-spotify</repository>
    <tag>${project.version}</tag>
    <buildArgs>
      <JAR_FILE>${project.build.finalName}-jar-with-dependencies.jar</JAR_FILE>
    </buildArgs>
  </configuration>
</plugin>

Answer 1

您使用的spotify/docker-maven-plugin当前处于无效状态。建议改用spotify/dockerfile-maven-plugin。

因此，将pom.xml文件的plugin部分更改为类似于

<plugin>
  <groupId>com.spotify</groupId>
  <artifactId>dockerfile-maven-plugin</artifactId>
  <version>${dockerfile-maven-version}</version>
  <executions>
    <execution>
      <id>default</id>
      <goals>
        <goal>build</goal>
        <goal>push</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <repository>spotify/foobar</repository>
    <tag>${project.version}</tag>
    <buildArgs>
      <JAR_FILE>${project.build.finalName}.jar</JAR_FILE>
    </buildArgs>
  </configuration>
</plugin>

注意：您也可以尝试使用JIB maven插件，该插件不需要安装docker并且可以在最低配置下工作。对于JIB，在命令中运行下面的命令足以完成任务

mvn compile com.google.cloud.tools:jib-maven-plugin:0.9.2:dockerBuild
