Docker-java API在windows 10中的Eclipse中连接virtualbox ubuntu docker
我在Windows 10上安装了virtualbox，并为docker主机创build了一个Ubuntu实例。 然后在Ubuntu上安装docker。 我想使用docker-java API（我使用docker-java 3.0.12）连接docker，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(); 我有以下信息：

我无法下载该DLL。 你能告诉我如何解决这个问题吗？
非常感谢！
我find了使用另一个Java API的解决scheme。 那是spotify / docker-client 。 我使用这样的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(); } }
它完美的作品。 现在我build议你可以使用下面的代码来访问docker。
干杯!
