写一段java docker client_Java 操作 Docker 使用 java 执行 Docker run 内部命令的代码

以下是一段Java Docker Client代码，可以使用Java操作Docker并执行Docker run内部命令：

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.HostConfig;
import com.github.dockerjava.api.model.PortBinding;
import com.github.dockerjava.core.DockerClientBuilder;
import com.github.dockerjava.core.command.ExecStartResultCallback;

public class DockerClientExample {

    public static void main(String[] args) {

        // 创建DockerClient
        DockerClient dockerClient = DockerClientBuilder.getInstance().build();

        // 配置端口映射
        ExposedPort tcp80 = ExposedPort.tcp(80);
        PortBinding portBinding = new PortBinding(PortBinding.parse("80"), ExposedPort.parse("80"));
        HostConfig hostConfig = HostConfig.newHostConfig().withPortBindings(portBinding);

        // 创建容器
        CreateContainerResponse container = dockerClient.createContainerCmd("nginx:latest")
                .withHostConfig(hostConfig)
                .withExposedPorts(tcp80)
                .withName("my-nginx")
                .exec();

        // 启动容器
        dockerClient.startContainerCmd(container.getId()).exec();

        // 执行Docker run内部命令
        dockerClient.execCreateCmd(container.getId())
                .withCmd("echo", "Hello World")
                .exec(new ExecStartResultCallback());

        // 停止容器
        dockerClient.stopContainerCmd(container.getId()).exec();

        // 删除容器
        dockerClient.removeContainerCmd(container.getId()).exec();
    }
}
