java怎么实现docker容器技术

<dependency>
    <groupId>com.github.docker-java</groupId>
    <artifactId>docker-java</artifactId>
    <version>3.2.2</version>
</dependency>

compile 'com.github.docker-java:docker-java:3.2.2'

import com.github.dockerjava.api.DockerClient;
import com.github.dockerjava.core.DockerClientBuilder;
import com.github.dockerjava.core.DockerClientConfig;
DockerClientConfig config = DockerClientConfig.createDefaultConfigBuilder().build();
DockerClient dockerClient = DockerClientBuilder.getInstance(config).build();

import com.github.dockerjava.api.command.CreateContainerResponse;
import com.github.dockerjava.api.model.HostConfig;
import com.github.dockerjava.api.model.PortBinding;
import com.github.dockerjava.core.command.PullImageResultCallback;
// 先拉取一个镜像
dockerClient.pullImageCmd("nginx:latest").exec(new PullImageResultCallback()).awaitSuccess();
// 创建一个容器
CreateContainerResponse container = dockerClient.createContainerCmd("nginx:latest")
    .withName("my-nginx-container")
    .withPortBindings(PortBinding.parse("80:80"))
    .withHostConfig(HostConfig.newHostConfig().withAutoRemove(true))
    .exec();
// 启动容器
dockerClient.startContainerCmd(container.getId()).exec();
