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： ```java 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(); ```
