java - 在 docker 中为 docker-client for java 设置容器端口

Question

我无法在docker中为容器设置publicPort和privatePort。我使用 java 库 docker-client for java 创建 docker 容器 https://github.com/spotify/docker-client

我已经在本地创建了一个 Docker 镜像“mobillogix/selenium-chrome”。

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

    // Bind container ports to host ports
    final String[] ports = {"44444", "59004"};
    final String[] ports1 = {"4444", "5900"};

    final Map<String, List<PortBinding>> portBindings = new HashMap<String, List<PortBinding>>();
    for (String port : ports) {
        List<PortBinding> hostPorts = new ArrayList<PortBinding>();
        hostPorts.add(PortBinding.of("0.0.0.0", port));
        portBindings.put(port, hostPorts);
    }


    final HostConfig hostConfig = HostConfig.builder().portBindings(portBindings).build();

    final ContainerConfig containerConfig = ContainerConfig.builder()
            .hostConfig(hostConfig)
            .image("mobillogix/selenium-chrome").exposedPorts(ports1)
            .build();

    final ContainerCreation creation = docker.createContainer(containerConfig);
    final String id = creation.id();

    // Start container
    docker.startContainer(id);

    final List<Container> containers = docker.listContainers();

    webDriver();

    // Kill container
    docker.killContainer(id);

    // Remove container
    docker.removeContainer(id);

此代码创建容器:

CONTAINER ID        IMAGE                        COMMAND                  CREATED             STATUS              PORTS                NAMES
6beec961dfcf        mobillogix/selenium-chrome   "/opt/bin/entry_point"   4 seconds ago       Up 2 seconds        4444/tcp, 5900/tcp   elegant_kare

带端口

4444/tcp, 5900/tcp

但我想创建带有端口的容器:

0.0.0.0:44444->4444/tcp, 0.0.0.0:59004->5900/tc

根据documentation ，这里正确的语法是:

hostPorts.add(PortBinding.of("0.0.0.0", 44444));
portBindings.put(4444, hostPorts);

hostPorts.add(PortBinding.of("0.0.0.0", 59004));
portBindings.put(5900, hostPorts);

您在循环中执行的操作是:

hostPorts.add(PortBinding.of("0.0.0.0", 44444));
portBindings.put(44444, hostPorts);

hostPorts.add(PortBinding.of("0.0.0.0", 59004));
portBindings.put(50004, hostPorts);
