我使用 Java 构建 Docker 映像。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" ]

它是一个非常简单的 Dockerfile，仅用于测试。

但我无法通过 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： 码头工人环境 我的客户是：

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

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

错误信息是：

谁能帮我提供一些想法？提前谢谢。

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();
