写一段java操作docker创建以及销毁的代码

好的，以下是一段Java代码，可以用来操作Docker创建和销毁容器：

import com.github.dockerjava.api.DockerClient;
import com.github.dockerjava.api.command.CreateContainerResponse;
import com.github.dockerjava.api.model.ExposedPort;
import com.github.dockerjava.api.model.PortBinding;
import com.github.dockerjava.core.DockerClientBuilder;
import com.github.dockerjava.core.command.PullImageResultCallback;

public class DockerManager {

    private DockerClient dockerClient;

    public DockerManager() {
        dockerClient = DockerClientBuilder.getInstance().build();
    }

    public void createContainer(String imageName, String containerName, int hostPort, int containerPort) {
        dockerClient.pullImageCmd(imageName).exec(new PullImageResultCallback()).awaitSuccess();
        ExposedPort tcp = ExposedPort.tcp(containerPort);
        PortBinding binding = new PortBinding(Ports.Binding.bindPort(hostPort), tcp);
        CreateContainerResponse container = dockerClient.createContainerCmd(imageName)
                .withName(containerName)
                .withExposedPorts(tcp)
                .withHostConfig(new HostConfig().withPortBindings(binding))
                .exec();
        dockerClient.startContainerCmd(container.getId()).exec();
    }

    public void destroyContainer(String containerName) {
        dockerClient.stopContainerCmd(containerName).exec();
        dockerClient.removeContainerCmd(containerName).exec();
    }
}

这段代码使用了Docker Java API来创建和销毁容器。在创建容器时，需要指定镜像名称、容器名称、主机端口和容器端口。在销毁容器时，只需要指定容器名称即可。
