Can you confirm it @vrapolinario ?
Yes. In the Docker docs, it is stated that as long as Microsoft supports the OS, Docker will support Docker Desktop on it. Please note that in any case, Docker Desktop is not supported on Server - neither 2019 or 2022. On Server, you run Docker CE/Moby or containerd. I recently suggested an update to the Docker docs to make that clear: Install Docker Desktop on Windows | Docker Docs
Docker only supports Docker Desktop on Windows for those versions of Windows that are still within Microsoft’s servicing timeline. Docker Desktop is not supported on server versions of Windows, such as Windows Server 2019 or Windows Server 2022. For more information on how to run containers on Windows Server, see Microsoft’s official documentation.
So, from a Docker Desktop standpoint this point is moot. You can run containers on Windows Server with - as mentioned - Docker CE/Moby or containerd. If you can upgrade to 2022, great. If you can’t, you can still run containers on Windows Server 2019 in a secure way, but you won’t benefit from new features.
