Question

我在dcos上使用marathon-lb。当负载增加时，我得到一个错误＆＃39;达到最大连接数＆＃39;和马拉松-lb失败。

所以我试图让多个marathon-lb实例运行在同一个节点上，配置如下。但这不起作用，当我尝试健康检查时失败。另一方面，如果我给出hostport值（9090），则一个实例成功运行，第二个实例继续等待。所以无论我有什么工作都无法工作。

不是Brdige网络支持来帮助运行多个实例吗？任何帮助表示赞赏..

如果您使用内部网络通信进行应用，则至少有2个免费的公共代理或将其从“外部”更改为“内部”，当您向群集DCOS添加新节点时，您可以设置为公共代理，一次这个节点中的马拉松负载，所以你DNS将在这个ip中解析域

通过Bridge网络的Marathon-LB多个实例不起作用
