我遇到一个问题，即无法从在Minikube的Kubernetes Pod中运行的应用程序访问在主机上运行的应用程序。
在这种情况下，在主机上运行的应用程序是Postgre DB，在pod中运行的应用程序是psql，实际上它是我开发的dotnet核心应用程序，但是我在这里使用psql进行仿真
Operating System : Windows 10 Pro
Minikube version : 0.30.0
Kubernetes version : 1.11.0
VM driver : HyperV
我的主机网络如下：
Ethernet adapter vEthernet (DockerNAT):
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::7970:dbd6:f9ab:b9b0%18
IPv4 Address. . . . . . . . . . . : 10.0.75.1
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . :
Ethernet adapter vEthernet (Primary Virtual Switch):
Connection-specific DNS Suffix . :
IPv4 Address. . . . . . . . . . . : 192.168.100.33
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.100.1
Ethernet adapter vEthernet (Default Switch):
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::241f:1091:ab14:ff1c%24
IPv4 Address. . . . . . . . . . . : 172.24.251.177
Subnet Mask . . . . . . . . . . . : 255.255.255.240
Default Gateway . . . . . . . . . :
在HyperV设置中，我已将Default Switch选择为minikube VM的Virtual Switch。我尝试使用Primary Virtual Switch，但它也无法正常工作。
Default Switch是内部网络连接类型。
Primary Virtual Switch是“外部网络连接”类型。
Minikube网络看起来像这样：

<I omitted the remaining veth interfaces>
我确信Postgre DB可以从任何地方访问，因为当我尝试从在Docker Swarm中部署的Docker容器中运行的应用程序访问它时，它能够成功连接，并且我还设置了pg_hba。对此：
# TYPE DATABASE USER ADDRESS METHOD
host all all 127.0.0.1/32 md5
host all all 0.0.0.0/0 md5
host all all ::1/128 md5
host replication all 127.0.0.1/32 md5
host replication all ::1/128 md5
我试图找到问题根源的其他一些事情
kubectl run -i --tty myalpine --image=alpine -- sh

Is the server running on host "172.24.251.177" and accepting
TCP/IP connections on port 5432?
你们中有些人也遇到过这个问题吗？还是我这里想念的东西？
谢谢。
