How to get output of docker executed command in docker-java library

Question

I am trying to pull an alpine image using docker-java library. Image got pulled successfully but I am not seeing any docker output on console. How to enable logging in docker-java library.

public class DockerPull {
   
    public static void main(String[] args) throws InterruptedException {
        DockerClientConfig standard = DefaultDockerClientConfig.createDefaultConfigBuilder().build();

        DockerClient dockerClient = DockerClientBuilder.getInstance(standard).build();

        dockerClient.pullImageCmd("alpine:latest").exec(new PullImageResultCallback()).awaitCompletion(3600, TimeUnit.SECONDS);
    }
}

Output: Process finished with exit code 0
