Enhancement/Added Containerfile

[fldu]

Hello,

Just adding some Containerfile for lazy people who just want to spin up a container on their laptop.

Cheers

Thanks @fldu! Can you elaborate on what problem you're aiming to solve with this one?

Hello @swagitda, thanks for your answer! It is true that a Containerfile is not needed for now as you just have to clone the project and open the html file, however this commits stands more for people who wants to build a container image with the project and be able to push it directly on some container cluster. As well, depending on evolution of the project, it might be interesting to have a container image that makes the thing "just work".

I see this being useful for offline use. Some organizations are not fond of online diagramming apps for data leakage concerns.
