I am running a windows docker container on a Windows Server 2016 host, running default configuration.
When running the docker container using the command:
docker run -it microsoft/windowsservercore powershell
When I run the command:
It just says that the request times out. I have checked that I can ping 220.127.116.11 and google.com etc... and even other machines on the same subnet. The only one I cannot ping is the host.
I have added '--dns ' to the 'docker run' command but this only allows me to ping the host machine via hostname and not IP.
Has anyone else seen this problem and have a solution?
I found a workaround (I'm not willing to call it a solution):
Windows Container Network Drivers: create a 'transparent' network:
docker network create -d transparent trans
Attach container to this network
docker run --network=trans ...
Important: Please note, that with this network, your container needs to obtain an IP Adress from the Host Subnet and it is directly exposed to it.
According to https://github.com/Microsoft/Virtualization-Documentation/issues/253#issuecomment-217975932 (JMesser81):
This is a known limitation in our Windows NAT implementation (WinNAT) that you cannot access the external port in a static port mapping directly from the container (NAT) host.
