我已经在windows 10上安装了virtualbox，并为docker主机创建了一个Ubuntu示例。然后在Ubuntu上安装了docker。我想使用docker-java API连接docker（我使用的是docker-java 3.0.12），代码如下：

DockerClientConfig config = DefaultDockerClientConfig.createDefaultConfigBuilder()
                    .withDockerHost("tcp://192.168.5.31:2375").build();
DockerClient dockerClient = DockerClientBuilder.getInstance(config).build();

CreateContainerResponse container1 =
dockerClient.createContainerCmd("tomcat:latest").withCmd("sleep", "9999") .withName("mytomcat3").exec();

dockerClient = DockerClientBuilder.getInstance().build();
dockerClient.startContainerCmd(container1.getId()).exec();

我得到了以下信息：

我无法下载dll。你能告诉我如何解决这个问题吗？
非常感谢！

我已经找到了一个使用另一个Java API的解决方案，即spotify/docker-client。我使用的API如下：

import java.net.URI;
import java.util.Arrays;

import com.google.common.collect.ImmutableMap;
import com.spotify.docker.client.DefaultDockerClient;
import com.spotify.docker.client.DockerClient;
import com.spotify.docker.client.LogStream;
import com.spotify.docker.client.messages.ContainerConfig;
import com.spotify.docker.client.messages.ContainerCreation;
import com.spotify.docker.client.messages.ExecCreation;
import com.spotify.docker.client.messages.HostConfig;
import com.spotify.docker.client.messages.HostConfig.Bind;
import com.spotify.docker.client.messages.PortBinding;

public class MyDocker {

public static void main(String[] args) {
    try {
        DockerClient dockerClient = DefaultDockerClient.builder()
                    .uri(URI.create("http://192.168.5.31:2375"))
                    .build();
        // Pull an image
        //docker.pull("tomcat");

        String p = PortBinding.randomPort("192.168.5.31").hostPort();

        final HostConfig hostConfig = HostConfig.builder()
                .appendBinds(Bind.from("/home/cdh/test")
                           .to("/usr/local/tomcat/webapps/test").readOnly(false)
                           .build())
                .portBindings(ImmutableMap.of("8080/tcp", Arrays.asList(PortBinding.of("0.0.0.0", p)))).build();    

        final ContainerConfig containerConfig = ContainerConfig.builder()
                .hostConfig(hostConfig)
                .image("tomcat:latest").exposedPorts("8080/tcp")
                .build();

        final ContainerCreation creation = dockerClient.createContainer(containerConfig);
        final String id = creation.id();

        // Start container
        dockerClient.startContainer(id);
        // Exec command inside running container with attached STDOUT and STDERR
        final String[] command = {"bash", "-c", "ls"};
        final ExecCreation execCreation = dockerClient.execCreate(
            id, command, DockerClient.ExecCreateParam.attachStdout(),
            DockerClient.ExecCreateParam.attachStderr());
        final LogStream output = dockerClient.execStart(execCreation.id());
        final String execOutput = output.readFully();

        // Kill container
        dockerClient.killContainer(id);

        // Remove container
        dockerClient.removeContainer(id);

        // Close the docker client
        dockerClient.close();

    } catch (Exception e) {
        e.printStackTrace();
    }
}

现在我建议你可以使用下面的代码来访问Docker。

junixsocket版本2.0.4不支持Windows。您需要升级到更高版本。
尝试将junixsocket依赖项更改为

<dependency>
  <groupId>com.kohlschutter.junixsocket</groupId>
  <artifactId>junixsocket-core</artifactId>
  <version>2.5.2</version>
  <type>pom</type>
</dependency>
