Publish server as docker container

How viable is it, has the topic come up at some point? As far as I know, it is not supported officially to run Unity (either the editor or player) from a docker container.

I understand that the server part is coupled to Unity and it is not possible to deploy a pure .NET solution no?

Using a docker image for your server is supported.
The binary can be a linux build of your unity server or something 100% custom.
You can also upload your linux server directly if you don’t wish to use docker.
