Editing Grafana Front End on QNAP


I’ve already managed to edit some parts of the front end of Grafana on a Windows 10 machine, where I could just build from source and then I could find the necessary files, which I had to edit, but now I wanted to host Grafana on a QNAP server. However I’ve only found one option to install Grafana on it - with Docker. After that I can’t seem to find the HTML and CSS files that I’d like to edit and even if I do find them eventually I’m not sure if I’d be able to build the frontend, since that is also an obligatory step (at least on a Windows machine).

So has anyone tried something like that? Is it even possible?
