[SOLVED] "docker-machine ip" does not work on my Windows 10 Pro

Docker Desktop for Windows
1

I changed PC because my previous computer was too slow.
I installed Windows 10 Pro 64bit and updated everything on new hardware.
Later I installed “Docker for Windows Installer.exe”.
Finally I opened the Windows command prompt and created my image and its container. It seems that everything went well but when I type “docker-machine ip” to find the IP to which my container is listening I get this error message:

“Error: No machine name (s) specified and no” default “machine exists”

I’m sure it’s not a Docker problem or a problem of my code because everything worked perfectly on the previous PC.
How do I solve?
Thank you

Do I have to install the Docker Toolbox?
Do I need to install Kitematic-Windows?
Do I have Virtualbox installed on Windows?
Do I have to have a specific version of Virtualbox?
Why Kinematic-Windows does not install?

Why nobody answers me? has the docker support for windows 10 been deleted?
Can I have any sign of your presence?

Thank you

I tried to watch this video:


I can tell you with absolute certainty that “Docker Quickstart Terminal” does not provide the IP.

Maybe I solved it by myself. I will continue to test docker in the coming days. Maybe I even found the bug.
