从Ubuntu主机访问在来宾KVM上运行的Docker容器应用

时间：2018-09-17 21:25:30

标签： docker ubuntu-16.04 virtualization kvm windows-server-2016

我的设置是：

  1. 在无头设备（主机）上运行的Ubuntu 16.04服务器
  2. 在主机顶部运行的Windows Server 2016 KVM（来宾）。
  3. 主机和访客之间的网络类型是NAT。整个事情都在公司后面。代理。
  4. 主机正在从公司网关获取静态IP。

在KVM上，我正在运行docker容器应用程序，该应用程序从内部和外部在端口15417上侦听（docker ps：0.0.0.0:15417-> 15417 / tcp） 容器IP地址为192.168.122.35，而来自NAT的KVM IP地址为：192.168.122.82

在docker容器上运行的应用公开了一个API，该API应该从kvm_ip：15417 / api上的linux主机进行访问

事实：

  1. 在Windows固件上打开端口15417进行入站TCP连接。
  2. 从主机到kvm IP（192.168.122.82）的ping操作正常
  3. 可以在192.168.122.35:15417/api上访问应用程序api
  4. docker日志，显示日志，以便应用程序启动并运行。

问题：

  1. 无法从localhost：15417 / api或127.0.0.1:15417/api上的KVM访问API，我得到的curl localhost:15417/api响应是：
  

目标主机无法访问

  1. 无法从主机上的192.168.122.82:15417/api（KVM_IP）访问API，curl 192.168.122.82:15417/api上的响应与kvm powershell上的响应相同。
  2. 没有从主机到192.168.122.82 15417的telnet或从来宾到telnet 127.0.0.1 15417的telnet，而到RDP（3389）或vnc（5900）等其他端口的telnet工作正常，这意味着这些端口都已打开。

这是我的主机“ ifconfig”：

以及我的KVM（访客）网络默认配置：

<network>
  <name>default</name>
  <uuid>9f80b5ad-b4fa-4c7e-a559-d27c23328347</uuid>
  <forward mode='nat'/>
  <bridge name='virbr0' stp='on' delay='0'/>
  <mac address='52:54:00:17:94:ca'/>
  <ip address='192.168.122.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.122.2' end='192.168.122.254'/>
    </dhcp>
  </ip>
</network>

最后，KVM网络接口配置为：

<interface type='network'>
  <mac address='52:54:00:fc:b7:f1'/>
  <source network='default' bridge='virbr0'/>
  <target dev='vnet0'/>
  <model type='rtl8139'/>
  <alias name='net0'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>

在尝试找出导致我从主机访问KVM上的应用程序中断的原因时，我很挣扎。
