我正面临这种情况,我的基于 Windows 的容器失去了解析 DNS 的能力。

这就是发生的事情

启动一个容器来测试 dns 解析 docker run -it microsoft/windowsservercore powershell

从容器内部

Test-NetConnection google.com -Port 443

失败

PS C:> Test-NetConnection google.com -Port 443 警告:google.com 的名称解析失败 -- 状态:这通常是主机名解析期间的临时错误,意味着本地服务器没有收到来自权威服务器的响应ComputerName:google.com RemoteAddress:InterfaceAlias:SourceAddress:PingSucceeded:False

但应该是这样的

PS C:\Users\asarafian> Test-NetConnection google.com -Port 443 ComputerName : google.com RemoteAddress : 216.58.204.14 RemotePort : 443 InterfaceAlias : vEthernet (External Virtual Switch) SourceAddress : 10.98.5.139 TcpTestSucceeded : True

我总是使工作站(Windows 10)休眠,并在其上运行 Hyper-V 实例和 Docker。工作站是 Windows 10,据我所知,当问题发生时,它使用 Windows 10 主机的 IP 作为 DNS。

从容器内

PS C:\> ipconfig /all

172.19.128.1是我的 Windows 10 主机 IP。

同时,当 Windows 10 主机容器卡住时,其他一切都正常解析 DNS。

  • Windows 10 上的任何进程。
  • Windows 10 上的 Hyper-V 实例。
  • 容器托管在 Windows 10 上的 Hyper-V 实例上。

重新启动机器并不能解决问题。这是第二次出现这种情况。以前我不得不重置整个 docker 安装来解决这个问题。我想避免这种情况并了解问题所在以及如何解决。

根据@chris-lawrence 评论的要求,以下内容ipconfig /all来自主机和容器内部。有趣的方面是 dns 解析在容器内部工作。

出于好奇,我检查了 hyper-v 实例的状态,它们已关闭。我的感觉是,当 hyper-v(s). 我最怀疑的是,当系统在 hyper-v 实例运行时从休眠状态恢复时会发生一些奇怪的事情。我去查一下......

我做了检查,一切都还好。但是 hyper-v(s) 是为有线网络适配器设置的,因此在 WIFI 上则没有网络。可能是在这种情况下他们不干涉。

更新 3 - 问题已修复

我刚刚升级到 Windows 10 创建者更新,突然问题就停止了。目前,我认为通过 Windows 更新解决了这个问题。但是对于遇到类似问题的人来说,我在更新方面只落后了一周,我不认为这是问题所在。是否会再次发生有待观察。

Docker 示例之一告诉您运行此命令:

  RUN Set-ItemProperty -path 'HKLM:\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters' -Name ServerPriorityTimeLimit -Value 0 -Type DWord

这应该解决 Windows 容器内的 DNS 的一些问题。不确定它会帮助你,但值得一试。
