使用java客户端启动docker容器时连接被拒绝

Question

我是docker新手，我想使用java客户端启动docker容器，

我试过了https://github.com/docker-java/docker-java如下

package containers.launch_containers;

import com.github.dockerjava.api.DockerClient;
import com.github.dockerjava.core.DockerClientBuilder;

public class StartContainers{
     DockerClient dockerClient;

    public StartContainers() {
        startContainers();
    }

    public void startContainers() {
           try {

                dockerClient = DockerClientBuilder.getInstance("tcp://127.0.0.1:2375").build();
                //starting the container of hello-world 
                dockerClient.startContainerCmd("hello-world").exec();


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

    public static void main(String args[])
    {
        StartContainers startContainers=new StartContainers();
    }   
}

在bashrc中设置所需的配置

出口DOCKER_HOST=tcp://127.0.0.1:2375

导出DOCKER_OPTS=“-H”tcp://127.0.0.1:2375-Hunix:///var/run/docker.sock"

localhost中的Docker映像

我有这个例外

launch_containers处理异常：launch_containersHttpHostConnectException：连接到launch_containers[/rrors.process]失败：连接拒绝（连接拒绝）rrors.java:228ApacheCorg.glassfish.jersey.process.internal.（ApacheCcope.run）cope.java:444ClientRorg.glassfish.jersey.client.（ClientRnvocation.invoke）nvocation.java:681杰西调用$org.glassfish.jersey.client.（杰西uilder.method）org.glassfish.jersey.client.杰西调用$1.call（杰西nvocation.java:681）在org.glassfish.jersey.internal.Errors.process（Errors.java:315）在org.glassfish.jersey.internal.Ejavax.ws.rs.（Eorg.apache.http.conn.）在127.0.0.1:2375E127.0.0.1（Eorg.glassfish.jersey.apache.connector.）在onnector.apply请求onnector.java:481内窥镜（请求org.glassfish.jersey.client.）在untime.invoke杰西untime.java:252（杰西org.glassfish.jersey.client.）在1.call杰西调用$Bnvocation.java:684（杰西调用. java： 437）在org. glassfish. jersey. client。杰西调用$Builder. post（杰西调用. java： 343）在com. github. dockerjava. jaxrs。StartContainerCmdExec.执行（StartContainerCmdExec. java： 29）在

我解决了这个问题，我应该得到容器ID，如下所示

   dockerClient = DockerClientBuilder.getInstance().build();
    //starting the container    
   CreateContainerResponse container = dockerClient.createContainerCmd("hello-world")
           .withCmd()
           .exec();
   dockerClient.startContainerCmd(container.getId()).exec();
   //stop the container 
   dockerClient.stopContainerCmd(container.getId()).exec();
