我在nodejs-jenkins pod上运行了一个Karma测试，npm超时连接到Chrome实例(在selenium hub上(
直到昨天，这一切都很好，没有对任何配置文件进行任何更改，所以我怀疑是底层基础设施连接故障
请注意，使用我的本地Chrome实例，测试在本地运行得非常好
我的配置看起来像：
browsers: ['RemoteChrome'],
singleRun: true,
autoWatch: false,
hostname: getIpAddress('eth0', 'IPv4'), // On Kubernetes, the container's network is on eth0
port: getRandomPort(), // Random port is enough for now
browserNoActivityTimeout: 600000,
browserDisconnectTolerance: 5,
customLaunchers: {
'RemoteChrome': {
base: 'WebDriver',
config: {
hostname: 'selenium-hub.MY_COMPANY_DOMAIN.com',
port: 80,
},
browserName: 'chrome'
}
}
成功构建的日志如下所示：

我已经尝试过这里提出的解决方案，但它不起作用
请注意，我的selenium集线器运行得很好，我可以ping它并在浏览器上显示它的集线器输出
有人有这个问题的经验吗？
我修复了这个问题，它确实是因为连接问题
我手动删除了selenium-hub pod，kubernetes部署重新创建了一个pod，该pod显然没有很好地连接到其服务
无论如何，在重新部署所有组件(部署、服务和Ingress(后，一切都重新同步，问题消失了
