docker-java创建Swarm Service绑定Volume的实现方案

你正在使用docker-java库操作Docker Swarm服务，绑定Volume仅需在ContainerSpec配置中追加Mount规则即可，现有拉取镜像、创建服务的逻辑无需大幅改动。

完整修改后的代码示例

import com.github.dockerjava.api.model.Mount;
import com.github.dockerjava.api.model.MountType;

// 原有拉取镜像逻辑不变
dockerClient.pullImageCmd(image).withTag(tag)
        .exec(new PullImageResultCallback());

// 构建Mount规则，两种场景二选一即可
// 场景1：命名卷挂载，将名为app-data的卷挂载到容器内的/opt/app/data路径
Mount volumeMount = new Mount()
        .withType(MountType.VOLUME)
        .withSource("app-data")
        .withTarget("/opt/app/data");

// 场景2：本地目录绑定，将宿主机/host/data路径挂载到容器内的/opt/app/data路径
// Mount bindMount = new Mount()
//         .withType(MountType.BIND)
//         .withSource("/host/data")
//         .withTarget("/opt/app/data");

ServiceSpec serviceSpec = new ServiceSpec()
        .withMode(new ServiceModeConfig()
                .withReplicated(new ServiceReplicatedModeOptions()
                        .withReplicas(1)))
        .withName(trname)
        .withTaskTemplate(new TaskSpec()
                .withContainerSpec(new ContainerSpec()
                        .withImage(image)
                        // 追加Mount配置，支持传入多个Mount对象实现多路径挂载
                        .withMounts(volumeMount)
                ));
String serviceId = dockerClient.createServiceCmd(serviceSpec).exec().getId();
