Docker-java API在windows 10上的Eclipse中連接virtualbox ubuntu docker

Question

我在Windows 10上安裝了virtualbox併爲docker主機創建了一個Ubuntu實例。然後在Ubuntu上安裝docker。我想用碼頭工人的Java API連接泊塢窗（我用的碼頭工人的Java 3.0.12），代碼如下：

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(); 

我已經得到了如下信息：

我無法下載該DLL。你能告訴我如何解決這個問題嗎？

非常感謝！

我找到了使用其他Java API的解決方案。那是spotify/docker-client。我使用這樣的API：

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(); 
    } 
} 

它完美地工作。現在我建議你可以使用下面的代碼來訪問docker。

乾杯！
