Question

我正在尝试使用Spotify Docker Client在Docker容器中使用Docker for Mac自动管理我的应用程序。

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调用失败：

2091 [jersey-client-async-executor-0] DEBUG org.apache.http.impl.conn.PoolingHttpClientConnectionManager  - Connection request: [route: {}->unix://localhost:80][total kept alive: 0; route allocated: 0 of 100; total allocated: 0 of 100]

Due to some weirdness，其中stacktrace提到unix://localhost:80，它实际上是使用套接字网址unix:///var/run/docker.sock。我通过调试器逐步证实了这一点。

Docker的工作方式非常好;我可以通过＆＃39; curl＆＃39;连接到插座。我可以通过终端正常使用docker。

JUnit测试中的Java Docker客户端无法连接到守护进程
