Hi! Since we do not provide Windows droplets we do not have any documentation on using docker for Windows. Docker themselves, however do provide a nice getting started guide here that should help you.

Hello all,

Unfortunately at this time, we do not have native support for Windows OSs on Droplets. You may be able to achieve this however by creating your own custom Windows ISO image and then using that when creating your Droplet.

Currently, DigitalOcean only allows the deployment of Linux based OS’s.

NOTE: This is not natively supported on the platform (choosing a Windows OS when you deploy your droplet).

We’d recommend that you add your vote to the Windows Server idea on our Product Ideas Board as well as comment on your use-case there so that our teams can better understand your needs.

I will also recommend checking the article that ryanpq shared

Hope that helps!
Regards,
Alex
