I use Visual Studio 2015 to publish a docker image to a Linux server. The similar step is on the link.
I get a failed message when you attempt to validate the connection to your Docker host in the Publish Web dialog box.
So I followed the help.
There is a command which is
--tls -H tcp://contoso.cloudapp.net:2376 info
I am not sure in which place to run this command. Because if I run it under
C:\Windows\system32. It can not be found
