Question

我试图通过https://github.com/docker-java/docker-java

使用java client api列出docker镜像

这是我的代码段

import java.util.List;
import com.github.dockerjava.api.DockerClient;
import com.github.dockerjava.api.model.Image;
import com.github.dockerjava.core.DockerClientBuilder;
    public class StartContainers{
        DockerClient dockerClient ;
        public StartContainers() {
            startContainers();
        }

    public void startContainers() {

        dockerClient = DockerClientBuilder.getInstance("tcp://localhost:2375").build();
        List<Image> images = dockerClient.listImagesCmd().exec();

        for(int i=0; i < images.size(); i++){
            System.out.println(images.get(i));
        }

    }

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

我得到了这个例外

线程“main”中的异常java.lang.ExceptionInInitializerError at org.glassfish.jersey.client.JerseyWebTarget。（JerseyWebTarget.java:71）在 org.glassfish.jersey.client.JerseyClient.target（JerseyClient.java:290）在 org.glassfish.jersey.client.JerseyClient.target（JerseyClient.java:76）在 com.github.dockerjava.jaxrs.JerseyDockerCmdExecFactory.init（JerseyDockerCmdExecFactory.java:234）在 com.github.dockerjava.core.DockerClientImpl.withDockerCmdExecFactory（DockerClientImpl.java:161）在 com.github.dockerjava.core.DockerClientBuilder.build（DockerClientBuilder.java:47）在 com.cit.security.controllers.StartContainers.startContainers（StartContainers.java:18）在 com.cit.security.controllers.StartContainers。（StartContainers.java:13）在 com.cit.security.controllers.StartContainers.main（StartContainers.java:29）引起：java.lang.RuntimeException：无法创建jax-rs RuntimeDelegate at javax.ws.rs.ext.RuntimeDelegate.getInstance（RuntimeDelegate.java:149）在javax.ws.rs.core.UriBuilder。（UriBuilder.java：56）

您能描述运行该代码的环境吗？我设法在Debian主机上成功运行该代码（作为maven项目），以root（sudo nohup docker daemon -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock &）运行docker守护程序并启动虚拟容器。

列出docker images
