Afternoon!
I am attempting to set up an Ansible Docker container for managing both
other containers running in Docker, as well as my host machine (Running
Windows 10).
Using Ansible 2.8, I'm attempting to get the SSH connection to my host
machine to work, as using WinRM isn't ideal for my scenario. I have set up
OpenSSH Server on my machine, and done all of the steps to allow SSH
tunneling from my container to my host machine. I can even go so far as to
"docker exec -it ansible bash" into my container, then run an "ssh
dockerhost" command, and it successfully uses my SSH keys to authenticate
and SSH back into my host machine.
My problem comes when I attempt to use Ansible from inside the container to
ping my host machine. Whenever I try to run "ansible dockerhost -m ping",
I'm met with this error:

I've also attempted this same ping test using the win_ping module, but get
a different failed result. The command hangs for an extended period of
time, then eventually returns with this error:

So I'm at a bit of a loss. I can independently confirm that the SSH setup
works, since I can SSH into and out of the Ansible container at will. I
also believe I set everything up correctly in terms of using the
experimental SSH connection to a Windows host.
My questions are these:
1) Is the ping command supposed to work with the Windows SSH feature? Or am
I looking to just make the win_ping module work correctly?
2) Is there something I'm missing in my setup? Or is this possibly a bug I
should report on the GitHub?
Thanks! And let me know if I can provide any additional details.
