Docker compose 网络不绑定 IP 地址

Question

我正在尝试从 docker compose 文件运行 selenium 网格。在这个 docker compose 中，我设置了一个 Ip 地址，因为我想在另一个 docker 镜像中的 jenkins 上运行测试。只有当我尝试使用设置 ip 地址运行测试时，才会出现以下错误

 org.openqa.selenium.remote.UnreachableBrowserException at RemoteWebDriver.java:573
        Caused by: java.net.UnknownHostException at InetAddress.java:800

这是我的 docker compose 文件

        config:

当我去 172.28.1.1:4444 时，我没有到达 selenium hub
