java - 无法使用Java创建docker镜像。错误消息是 “…: Error processing tar file(exit status 1): unexpected EOF”

Question

我使用Java构建Docker镜像。 Dockerfile和代码已准备就绪。我可以通过CLI成功构建镜像，例如:

docker build -t imgetest:1.0 .

我的Dockerfile是:

FROM node:6.14.2
EXPOSE 8080
COPY server.js .
CMD [ "node", "server.js" ]

这是一个非常简单的Dockerfile，仅用于测试。

但是我无法通过Java API构建。我的Maven依赖项和Java代码是:

<dependency>
    <groupId>com.github.docker-java</groupId>
    <artifactId>docker-java</artifactId>
    <version>3.2.1</version>
</dependency>

public boolean createImages(String repository, String dockerfilePath)
{
    try {
        // Loading from a source
        final File imageFile = new File(dockerfilePath);
        try (InputStream imagePayload = new BufferedInputStream(new FileInputStream(imageFile))) {
            dockerClient.createImageCmd(repository, imagePayload).exec();
            dockerClient.close();
            logger.info("Build image successfully.");
            return Boolean.TRUE;
        }
        catch (Exception e)
        {
            e.printStackTrace();
            dockerClient.close();
        }
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

    return Boolean.FALSE;
}

我的 docker 环境是:

我的客户是:

    public static DockerClient getClient()
    {
        DockerClientConfig config = DefaultDockerClientConfig.createDefaultConfigBuilder().build();

        DockerClient client = DockerClientBuilder
                .getInstance(config)
                .build();
        return client;
    }

错误消息是:

谁能帮助我提出一些想法？谢谢你

这是此问题的解决方案。这个对我有用。

BuildImageResultCallback callback = new BuildImageResultCallback() {
                    @Override
                    public void onNext(BuildResponseItem item) {
                        System.out.println("" + item);
                        super.onNext(item);
                        }
                    };
File baseDir = new File(dockerfilePath);
String imageId = dockerClient.buildImageCmd(baseDir).exec(callback).awaitImageId();
