Docker alternative for web server tutorial

[Nitrogly]

Hi everyone,

I'm a big fan of the wordpress-nginx tutorial and really appreciate how much effort put into it.
The complete tutorial with a web server on Ubuntu was especially helpful to me.

However, I do have one follow-up question:
Many people use Docker for such setups instead of a vanilla installation.
Is there a specific reason why Docker wasn't used in these tutorials? What's the opinion on that?

Also, would it be possible to create a tutorial on how to set up the same environment using a Docker container?
Or is there maybe already a docker project to download?

Thanks!
