我正在尝试使用Spotify Docker 客户端在 Docker 容器中自动管理我的应用程序，以进行与 Docker for Mac 的集成测试。

DockerClient docker = new DefaultDockerClient.fromEnv().build();

HostConfig hostConfig = HostConfig.builder()
    .portBindings(new HashMap<String, List<PortBinding>>(){{
        put("8080", Arrays.asList(PortBinding.of("localhost", 8080)));
    }}).build();

ContainerConfig containerConfig = ContainerConfig.builder()
    .hostConfig(hostConfig)
    .exposedPorts("8080")
    .image("my-app")
    .portSpecs(Arrays.asList("8080:8080"))
    .build();

ContainerCreation createdContainer = docker.createContainer(containerConfig);

createContainer通话失败：

由于堆栈跟踪提到的一些奇怪之处，unix://localhost:80实际上它实际上是在使用套接字 url unix:///var/run/docker.sock。我已经通过调试器逐步确认了这一点。

否则 Docker 工作得很好；我可以通过“curl”连接到套接字，并且可以通过终端正常使用 docker。
