I have installed the docker engine and successfully logged in, but I cannot successfully save the login data.
Let me show you what I did:

mystuff@mysuff:~/wolfram$ sudo docker run -it wolframresearch/wolframengine

I copied the info into the file ./Licensing/mathpass and then launched:

sudo docker run -it -v ./Licensing:/usr/share/Mathematica/Licensing wolframresearch/wolframengine

But it still asks for a email and password. I also tried to remove the first line (%(userregistered)) from the mathpass file and the last part (MyName MySurname), but nothing worked so far. Any idea? Thanks
