Making media files accessible from host

[eduherminio]

Thanks a lot for the detailed article @mjhea0.

I was able to follow it from start to end and the only part that didn't work for me was STATIC_ROOT = BASE_DIR / "staticfiles", where I'm getting TypeError: unsupported operand type(s) for /: 'str' and 'str', but replacing it with STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') made it work without major inconvenience.

Other than that, here's my main question: how can I make the media dir accessible from the host?

I tried in the same fashion as I was doing with my database (making sure the directory was created beforehand), but no luck.
Here's the relevant change: lynx-chess/OpenBench@cc99ad4

And here the sad result of the attempt.

You need to create a media dir in Dockerfile.
