Windows容器无法在Swarm中ping Ubuntu容器
我们正在尝试创build一个docker swarm，该docker swarm具有在Docker容器上运行的ASP.NET Docker服务，该容器通过运行在Ubuntu docker-machine上的Nginx服务提供服务。 问题是Windows容器没有正确响应群中的其他服务。 我们有Django应用程序使用相同的Nginx服务运行良好，但ASP.NET应用程序超时。我们进入Nginx容器，并成功地触及ASP.NET容器，但当我们进入ASP.NET容器请求正在发送到正确的IP但所有请求超时。
这里是我们所知道的这一点：
- Docker版本17.04.0-ce，构build4845c56
- 运行Windows Server 2016 – KB3150513
- 禁用防火墙来确认它不是端口的问题
- Windows容器在Docker实例上直接在Windows Server上运行
- Ubuntu容器在Ubuntu Docker机器上
