2 - Upload git repository forked in Back3App or run docker build . minetest
3 - Wait for Back4App run docker image or run manually typing in terminal docker run -it minetest

From what I can see so far: Whatever you're using to invoke Minetest ("back3app"? "back4app"?) is just passing a wrong command line: Looking at your screenshot, apparently running something like minetestserver --config /etc/minetest/minetest.conf. Minetest is just appropriately complaining about you not telling it which game to run.

That's a misunderstanding, the command line comes from our Dockerfile:

minetest/Dockerfile

Lines 81 to 82 in 9ab4478

	ENTRYPOINT ["/usr/local/bin/minetestserver"]
	CMD ["--config", "/etc/minetest/minetest.conf"]

Our documentation on this is lacking but I think to successfully use the docker image it should suffice if you bind mount a game to the right location in /var/lib/minetest/.minetest/games/, for example:
-v /real/path/to/minetest_game:/var/lib/minetest/.minetest/games/minetest_game

I solved the problem by assigning a path to the volume, as it is apparently mandatory. Appreciate it
